ASTM C1751-21 Standard Guide for Sampling Radioactive Tank Waste Active 发布日期 :  1970-01-01 实施日期 : 

4.1 Obtaining samples of high-level waste created during the reprocessing of spent nuclear fuels presents unique challenges. Generally, high-level waste is stored in tanks with limited access to decrease the potential for radiation exposure to personnel. Samples must be obtained remotely because of the high radiation dose from the bulk material and the samples, samples require shielding for handling, transport, and storage. The quantity of sample that can be obtained and transported is small due to the hazardous nature of the samples as well as their high radiation dose.4.2 Many high-level wastes have been treated to remove strontium (Sr) or cesium (Cs), or both, have undergone liquid volume reductions through pumping and forced evaporation or have been pH modified, or both, to decrease corrosion of the tanks. These processes, as well as waste streams added from multiple process plant operations, often resulted in precipitation, and produced multiphase wastes that are heterogeneous. Evaporation of water from waste with significant dissolved salts concentrations has occurred in some tanks due to the high heat load associated with the high-level waste and by pumping and intentional evaporative processing, resulting in the formation of a saltcake or crusts, or both. Organic layers exist in some waste tanks, creating additional heterogeneity in the wastes.4.3 Many of the sampling systems have limitations including the ability to sample varying depths in the tank and the depth of sampling. Sampling in Hanford tanks is constrained by riser diameter, riser location and riser availability.4.4 Due to these extraordinary challenges, substantial effort in research and development has been expended to develop techniques to provide grab samples of the contents of the high-level waste tanks. A summary of the primary techniques used to obtain samples from high-level waste tanks is provided in Table 1. These techniques will be summarized in this guideline with the assumption that the tank headspace is adequately ventilated during sampling.1.1 This guide addresses techniques used to obtain samples from tanks containing high-level radioactive waste created during the reprocessing of spent nuclear fuels. Guidance on selecting appropriate sampling devices for waste covered by the Resource Conservation and Recovery Act (RCRA) is also provided by the United States Environmental Protection Agency (EPA) (1).2 Vapor sampling of the head-space is not included in this guide because it does not significantly affect slurry retrieval, pipeline transport, plugging, or mixing.1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 This guide is used to distinguish soak tank metal cleaners that are excessively corrosive to metals (other than aluminum and its alloys which are covered by Method D930). The users will define the degree of corrosion considered excessive, in terms of weight loss per unit of surface area or in terms of changes in appearance, or both.1.1 This guide covers determination of the corrosive effects of soak tank metal cleaners on all metals other than aluminum and its alloys, under conditions of total immersion, by quantitative measurement of weight change or by qualitative visual determination of change. The test determines the effects of the cleaner on metals being cleaned, and does not determine the life of the cleaner or of the containing equipment.1.2 When the test is used to assist in the choice of material for a specific use, the test conditions should simulate the conditions of use as closely as practicable.1.3 Where no further processing subsequent to cleaning is indicated, a test for the effect of residual cleaner on the corrosion behavior of the material may be required.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.1 Extensional viscosity is a measure of the resistance of a liquid to stretching forces, such as those occurring during the disruption of liquid films and the formation of sprays used in agriculture and other purposes including painting operations or metal working. This method for measurement of a Screen Factor, gives a relative value for extensional viscosity, which may be used:4.1.1 To compare the potential for drift control of different polymers.4.1.2 To compare the relative extensional viscosity component of different spray tank mixtures.4.1.3 To determine the extent of breakdown of polymer solutions used as drift control additives during the recirculation of the solutions through pumps and screens.4.1.4 To use as a parameter in the Spray Drift Task Force Models for droplet size prediction.4.2 It should also be noted that many drift control polymers are irreversibly destroyed during the recirculation of spray mixes by pumping with high shear pumps such as gear or centrifugal pumps. It is advisable to subject the test mixture to similar pumping regimes to simulate practical conditions before carrying out the extensional viscosity test. Measurements of extensional viscosity are the only presently known method of determining the extent of this breakdown properties of dilute polymer solutions.4.3 This method is intended to produce a relative value for extensional viscosity. The purpose of the method is to compare the extensional viscosity produced by different polymer types or concentrations of polymer in spray tank mixes.1.1 This test method covers the determination of the relative extensional viscosity or Screen Factor (SF) of dilute agricultural spray mixes.1.2 The test can be used for tank mixes containing dissolved, emulsified or dispersed materials, or mixtures.1.3 Results may be affected by the quality of the water used. Make-up water quality should therefore be specified in the presentation of results.1.4 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination. Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice.NOTE 1: References to the development of extensional viscosity from dissolved polymers, extensional viscosity effects on the droplet size distribution of sprays, and measurements of screen factor on recirculated spray mixes containing polymers are available.2,31.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide may be used in the investigation of underground storage tank systems for equipment problems in a wide variety of applications. Use of this guide is voluntary. It is intended to assist users who want to investigate equipment failures, malfunctions, and other potential causes of suspected releases.4.2 The following groups of users may find the guide particularly helpful:4.2.1 Storage tank system designers and manufacturers;4.2.2 Storage tank installers, testers, and inspectors;4.2.3 Storage tank maintenance contractors;4.2.4 Storage tank removal contractors;4.2.5 Federal, state, tribal or local regulators, including departments of health, departments of environmental protection, and fire departments;4.2.6 Petroleum release remediation professionals;4.2.7 Insurance adjusters;4.2.8 Storage tank owners and operators;4.2.9 Consultants, auditors, and compliance assistance personnel.4.3 This guide is intended to assist in the development of protocols for determination of source and cause of a release and the investigation of a malfunction or failure of any component of a UST system and the implementation of said protocols. This guide outlines steps that may be necessary and include, but are not limited to initial evaluation of the UST system to determine if there has been a component failure preparation of samples of failed or compromised equipment for laboratory analysis; visual; and analytical evaluation of release indications; and documentation of the investigation. The guide provides a series of investigation options from which the user may design failure investigation protocols. The guide describes common investigation techniques in the order in which they might be employed in an investigation.4.4 A user may elect to utilize this guide for a number of reasons, which include, but are not limited to:4.4.1 To differentiate new releases from new discovery of old releases;4.4.2 To establish malfunction and failure rates of various UST system components;4.4.3 To determine expected life spans of various UST components;4.4.4 To identify opportunities for improving the performance and reliability of storage tank equipment;4.4.5 To focus inspection and maintenance efforts on those component of the UST system that are most prone to compromise, malfunction and failure;4.4.6 To identify those components of the UST system that require more frequent maintenance;4.4.7 To reduce equipment replacement costs;4.4.8 To prevent petroleum releases;4.4.9 To identify those conditions that may cause or contribute to equipment or component compromise, deterioration or other cause of malfunction or failure of the UST system;4.4.10 To comply with environmental regulations that require the investigation of suspected releases and determine the source and cause of releases; and4.4.11 To identify conditions that may cause or contribute to nonsudden releases that may not be detected by other leak detection methods.4.5 This guide may be used to establish a framework that pulls together the common approaches to investigation. The framework will allow the user to establish an investigation protocol to meet the user’s specific requirements. Specific user requirements will vary depending upon the purposes of the data collection and the decisions that the investigation is intended to support. This guide does not provide methods to establish specific user investigation requirements nor does it establish minimum levels of documentation.4.6 This guide will acquaint users with methods and tools that may be used in investigations of equipment problems associated with USTs. The user may include a subset of the methods described in this guide in their investigation. The user may consider a variety of factors in determining which combination of the methods to employ.4.7 This guide is not intended to require the user to conduct a failure investigation.4.8 This guide is focused on the identification, documentation, and preservation of compromised UST system equipment. It does not provide guidance on establishing root causes of compromise, malfunction or failure. The identification of root causes of compromise, malfunction or failure may require further expert analysis of the data and equipment collected during the failure investigation.4.9 Determination of equipment failures and evidence of the source and cause of a release are often unavailable due to the loss of critical information necessary to pinpoint equipment failures and conduct an investigation. Adjustment, repair or removal of failed equipment before determining and documenting the cause of the failure may interfere with the failure investigation. Failures may be caused by compatibility issues, manufacturer defects, corrosion, degradation, improper installation, damage, age, misuse, use or other causes. This guide may be used to identify techniques and procedures applicable to maintenance personnel and equipment vendors that will allow an investigator to evaluate possible equipment failures before equipment is adjusted, repaired, replaced or destroyed.4.10 This guide does not address all the safety measures that must be taken when removing and disassembling UST systems. Because most UST systems have contained flammable or combustible liquids special precautions should be taken to prevent fire, explosions and exposure to toxic vapors. API standard STD 2015 and RP 2016 address some of the safety considerations as do many of the procedures available from fire departments.1.1 Overview—This guide is an organized collection of information and series of options for industry, regulators, consultants and the public, intended to assist with the development of investigation protocols for underground storage tank facilities in the United States. While the guide does not recommend a specific course of action, it establishes an investigation framework, and it provides a series of techniques that may be employed to: identify equipment problems; in some cases collect and preserve failed equipment for forensic evaluation or laboratory analysis; identify the source of a release; and document the investigation. The guide includes information on methods of investigation, documentation, collecting and preserving samples; chain of custody; storage; shipping; working with equipment manufacturers; and notification of regulators and listing laboratories. The goal in using the guide is to identify the appropriate level of investigation and to gather and preserve information, in an organized manner, which could be used in the future to improve system design or performance. While this guide may act as a starting point for users with limited experience in failure investigation, the user is encouraged to consult with failure analysis experts for specific investigation procedures that may be needed for certain equipment and the investigation should be conducted by a qualified professional. As users develop their specific investigation protocols, they may find that the investigations can be streamlined for certain types of facilities.1.2 Limitations of This Guide: 1.2.1 Given the variability of the different investigators that may wish to use this guide and the different types of facilities and failures that will be investigated, it is not possible to address all the relevant standards that might apply to a particular investigation. This guide uses generalized language and examples to guide the user. If it is not clear to the user how to apply standards to their specific circumstances, it is recommended that users seek assistance from qualified professionals.1.2.2 This guide does not address safety issues associated with the investigation, taking samples and storing equipment. Users are cautioned to exercise proper care in handling equipment that was in contact with flammable and combustible liquids and vapors. Some of the activities described in this guide may be subject to OSHA (Occupational Safety and Health Administration) regulations or may only be conducted by individuals with appropriate HAZWOPER (Hazardous Waste Operations and Emergency Response) training certifications recognized by federal and state regulatory authorities, such as HAZWOPER training.1.2.3 This guide does not address laboratory investigations of material properties and detailed failure analysis.1.2.4 This guide does not cover underground storage tank systems storing liquefied petroleum gas (LPG).1.2.5 This guide does not replace state-required closure assessments and investigations. Requirements vary from state to state and often include specific sampling requirements. The user should comply with the requirement of the authority having jurisdiction.1.2.6 Prior to implementing the steps described in Section 5, users of this guide must determine if the authority having jurisdiction has any qualification requirements for the individual performing the investigation.1.2.7 Investigations addressed by this guide may involve knowledge, skills, and abilities generally attributed to individuals certified as tank systems installers, inspectors, or removers, or those who are trained in soil and groundwater sampling protocols (for example, geologists, groundwater professionals, or engineers).1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Environmentally sound management of underground storage tank systems involves a broad range of preventative maintenance activities directed toward preventing accidental releases of regulated substances, and effectively detecting and responding to such releases when, and if, they do occur. Numerous technical guidelines are presently available addressing specific procedures for release prevention and response for underground tank systems, including guidelines for tank system design, installation, operation and maintenance, leak detection, spill control, periodic equipment inspections, corrective action for affected environmental media, tank system closure, and operator training. This guide presents an overview, identifying key management considerations and referring the user to other related ASTM standards and industry guidelines for more detailed information.4.2 Tank System Design and Installation—The first step in environmentally sound management of tank systems is to design and install the tank system so as to minimize the potential for release of regulated substances to the environment. This guide addresses key considerations related to the types of tank systems to be used, compatibility of regulated substances to construction materials, types of spill containment and overfill prevention devices, corrosion protection, leak detection proper installation practices, and system operation.4.3 Preventative Maintenance—Even for properly designed and installed tank systems, practical measures are needed to detect and terminate leaks and respond to releases in a timely manner so as to minimize regulated substance losses and associated environmental effects. This guide reviews general considerations including release detection measures, possible indicators of a release, appropriate record-keeping procedures, tank system inspection, equipment testing, response planning and release control measures. Some preventative maintenance activities are recommended while others are mandated by state or federal regulations. This guide addresses federally mandated activities4.4 Inspections—Inspections are a critical component of a sound UST management plan. Both third-party professional and operator inspections can identify potential risks associated with component compromise and operational issues that may increase the risk of an uncontained release. Some inspections are required by regulatory requirements. The scope, frequency and necessary qualifications to perform required inspections vary by jurisdiction. This guide outlines the scope and schedule of federally required walkthrough inspections.4.5 Equipment Testing—Testing can confirm the functional status of various UST components. Some UST equipment and components must be tested in accordance with federal regulations. Spill prevention equipment and containment sumps used for interstitial monitoring of piping must be tested at least once every three years. Electronic and mechanical release detection components must be tested annually. Cathodic protection systems must be tested within six months of installation, then at least every three years and within six months of any repair activity. This guide outlines the scope and schedule of federally required equipment testing.4.6 Fueling Procedure—Careful loading, unloading, and dispensing of liquids to and from underground storage tanks is the most important day-to-day activity to ensure proper handling of liquids and prevention of releases. This guide is developed to addresses UST system management. Dispensers and dispensing activities may be sources of releases but are not considered a component of the UST system and are not include in the regulatory requirements addressed by this guide.4.7 Corrective Action for Affected Environmental Media—Following discovery and control of a release regulated substance from an underground tank system, corrective actions may be required for affected soil and groundwater as needed to protect human health, safety, and environmental resources. This guide reviews a risk-based process for investigation, evaluation, and remediation of affected environmental media consistent with the guidelines provided in Guide E2081.4.8 Tank System Closure—If it is determined that an underground tank system will no longer be used to store regulated substances, the system must be taken out of service, either temporarily or permanently, and, when appropriate, decommissioned and removed in a manner that minimizes the potential for future releases or safety hazards. This guide reviews the general procedures for properly removing tank systems from service, as well as the options for tank system closure by means of tank excavation and backfill placement or in-place closure methods.4.9 Tank Management Practice Education, and Operator Training—Personnel training is a key element of successful environmental management of UST systems. It is important that persons involved in the installation, operation, or maintenance of tank systems understand the release prevention, appropriate leak detection, and response procedures. This guide outlines the scope and schedule of several key training areas that may be appropriate depending on individual job assignments, including: tank system installation and maintenance; general measures for release prevention; leak detection equipment operation and maintenance; release control and emergency response measures; and regulated substance and waste handling measures. This guide outlines the scope of federally mandated operator training.4.10 Recognized Practice—Some federally mandated testing and inspection requirements can be satisfied by following a practice developed by a nationally recognized association or independent testing laboratory such as provided in 40 CFR §280.35(a)(1)(ii)(B) and 40 CFR §280.40(a)(3). Many such practices are referenced in this guide. Not all practices developed by nationally recognized associations or independent testing laboratories are accepted by the USEPA or the implementing agency. To determine if a practice satisfies the federal requirements, the owner or operator should consult with the implementing agency.1.1 The framework discussed in this guide is limited to facilities with underground storage tanks (USTs) storing regulated substances at ambient temperature and atmospheric pressure. This guide is not intended to provide detailed technical specifications for implementation of the approaches described in this document, nor to be used as an enforcement tool, but rather to identify the important information used for environmental management of underground tank systems. The term “must” is used where United States federal requirements apply. References to ASTM standards and other industry guidelines have been provided to address implementation of the approaches discussed in this guide. Many states and some local agencies have adopted rules that place additional responsibilities on the owners/operators of UST systems. Refer to state and local regulations that may contain additional requirements. It is not possible to identify all considerations or combinations of conditions pertinent to a unique underground storage tank system.1.2 This guide addresses principal considerations related to the prevention of, and response to environmental releases from tank systems and is organized in the sections listed below:    Section 1:  Section 2: Lists relevant ASTM Standards and other industry or regulatory guidance documents Section 3: Defines the key terminology used in this guide Section 4: Describes the significance and use of this guide Section 5: Tank System Design and Installation Section 6: Preventive Maintenance and Inspection Plan Section 7: Fueling Procedure Section 8: Dispensing Activities Section 9: Release Response Plan Section 10: Corrective Action for Affected Environmental Media Section 11: Tank System Closure Section 12: UST Management Practice and Operator Training Appendix X1: Recurring Release Detection and Cathodic Protection Requirements (Quick Glance) is intended to be a quick reference guide for monitoring information Related Material: Documents related to environmental management of underground storage tanks1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This specification covers commercial multiple-tank dishwashing machines of the continuous type, oval shaped, with horizontal table conveyor systems. According to direction of rotation, the dishwashing machines can be classified into two types: Type I-CW (clockwise) rotation is designed and supplied to accept the feeding of soiled tableware from the right side, when viewed from above and Type II-CCW (counterclockwise) rotation is designed and supplied to accept the feeding of soiled tableware from the left side, when viewed from above. These dishwashing machines can also be classified into three styles: Style 1 is a steam heated machine, with two classes namely Class A which uses injectors and Class B which uses heat exchange coils. Style 2 is an electrically heated dishwashing machine. Style 3 on the other hand is gas heated with two classes namely Class C which uses natural gas and Class D which uses LP gas. Furthermore, four types of arrangements for these machines can be made: Arrangement A is with tray rail and table-mounted garbage disposal machine; Arrangement B is with food waste trough instead of tray rail and garbage disposal machine in center of trough; Arrangement C is the same as Arrangement A, except disposal unit is not available; and Arrangement D is the same as Arrangement B, except that there is no disposal unit.
