This application guide applies to ac high-voltage (> 1000 V) circuit breakers rated for shunt reactor switching. This application guide provides the theoretical background of shunt reactor switching and how information obtained from test results should be used to predict overvoltages in the field, and gives suggestions how to mitigate these overvoltages.

This standard defines, for various types of instrumentation, the essential performance parameters, and general placement for monitoring the release of radionuclides associated with a postulated serious accident at a reactor facility. This standard does not specify which of the instruments or systems are required nor does it consider the number or specific locations of such instruments. This standard also does not address single failure criteria associated with nuclear safety instrumentation.… read more For the purpose of this standard, the predominant consideration in the assessment of radiation emergencies is the measurement of fission products promptly enough to permit timely emergency decisions to be made. Where instruments utilized for routine operations fulfilll the criteria herein, they need not be duplicated in order to have separate emergency instrumentation. Dual purpose instrumentation must meet the requirements of this standard. read less

This technical report covers results of a survey of the petroleum refining industry concerning the use of duplex stainless steel (DSS) in hydroprocessing reactor effluent air cooler (REAC) systems. The API Committee on Refining Equipment Subcommittee on Corrosion and Materials (SCCM) commissioned this survey after several industry reports of weldment cracking failures with DSS REAC system components, including REAC header boxes, tube-to-tubesheet welds, and associated piping. REAC component weldment cracking has been addressed in SCCM documents, including API Recommended Practice 932-B and API Technical Report 938-C, in published conference papers, and in a report issued by the Materials Technology Institute (MTI).
