troduced into the data as a result of scaling the experimental facility. Scenario Time sequence of events. Sensitivity Studies The term is generic to several types of analyses; however, the definition of most interest here relates to those studies associated 19 with the PIRT process and used to determine the relative importance of phenomena/ processes. This may also involve analysis of experimental data that are a source of information used in the PIRT process. Separate Effects An experiment in which the primary focus is on a single parameter or Test process. SER Safety Evaluation Report - A report by the NRC that evaluates a submittal and either accepts or rejects the proposals in the submittal. SRP Standard Review Plan - Acceptable plan for NRC reviewers in NUREG-0800. Transients In this SRP, accidents and transients refer to those events that are defined in NUREG-0800 to be analyzed to meet the requirements of the General Design Criteria (GDC), except for the fuel assembly misloading event and all radiological consequence analyses. Uncertainty There are two separate but related definitions of primary interest: a. The inaccuracy in experimentally derived data typically generated by the inaccuracy of measurement systems. b. The inaccuracy of calculating primary safety criteria or related figures of merit typically originating in the experimental data and/or assumptions used to develop the analytical tools. The analytical inaccuracies are related to approximations in solving the equations and constitutive relations. User Manual A document that includes modeling guidelines for the accident under consideration, procedures for selecting code inputs, and procedures for transferring information between different pieces of the evaluation model. 1 Copies are available at current rates from the U.S. Government Printing Office, P.O.
