ASME VVUQ 60.1 provides guidance to computational physics simulation software end users for evaluating and selecting simulation software appropriate for their intended application of interest. The selection should be guided by the level of risk associated with the application of interest. The software can be based on theoretical formulations or empirical data. Before selecting a particular simulation software (either commercial, open-source, or developed in-house), the end user must know its theoretical basis, dependability, and limitations relevant to the end userâ??s application of interest. This Guideline outlines some matters that the end user can take into consideration during the software selection process. A series of questions are also included to help the end user assess the suitability of the simulation software by weighing responses based on the risk associated with their application of interest. The scope of this Guideline is limited to computational physics simulation software. It does not offer guidance on other software. ASME VVUQ 60.1 has been developed to provide guidance to end users to evaluate simulation software based on its functionality. Other aspects such as cost are not considered. This Guideline is not limited to any physics or any specific engineering application.

This standard provides training requirements on the use of PRND instrumentation for the Response mission areas from Presidential Policy Directive 8 (PPD-8) that describes five preparedness capabilities: Response, Recovery, Mitigation, Prevention, and Protection. The PRND instrumentation addressed in this standard are described in the normative references in Clause 2. Training to use the same instrumentation for the Prevention and Protection mission areas is described in ANSI N42.37. Having ANSI… read more N42.37 training before ANSI N42.60 training may be helpful, but is not required. For non-PRND instrumentation, organizations may apply training requirements from this standard as needed and considered appropriate for their Response missions. read less

The requirements in this standard apply to all 50 Hz and 60 Hz, two-pole and four-pole, cylindrical-rotor synchronous generators driven by steam turbines and/or by combustion gas turbines. The drive may be direct or through a gearbox or other device that permits different speeds for the turbine and the generator. The generators covered by this standard are to have rated outputs of 10 MVA and above. Cylindrical-rotor, two-pole and four-pole generators below this rating are generally covered by NEMA MG 1.
