neered safeguards features actuation systems, and plant instrumentation systems. It reviews environmental qualification of electrical equipment important to safety. • Technical Specifications Branch (RTSB) develops, maintains, and updates standard technical specifications. It provides NRR interpretation of specific technical specification requirements and provides assistance in screening incoming change requests. • Operator Licensing, Human Performance, and Plant Support (IOLB) holds the responsibility for issues related to operator licensing, in-plant radiation protection, effluent release control, and emergency preparedness. It reviews issues related to emergency operating procedures, human factors engineering design, in-plant radiation protection, and effluent release control. • Office of Nuclear Regulatory Research (RES) assists the primary and secondary review branch, as requested, by providing necessary technical support. I. AREAS OF REVIEW Section 50.67, Accident source term, of 10 CFR Part 50 allows a holder of an operating license issued prior to January 10, 1997, and holders of renewed licenses under Part 54 of this chapter whose initial operating license was issued prior to January 10, 1997, to voluntarily revise the accident source term used in design basis radiological consequence analyses. Paragraph 50.67(b) requires that applications under this section contain an evaluation of the consequences of applicable DBAs previously analyzed in the plant’s FSAR. Potential changes in consequences could be due to the impact of the characteristics of the AST itself or from the proposed plant modifications. Regulatory Guide 1.183, Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors (Ref. 1), provides guidance to licensees on performing evaluations and reanalyses in support of the implementation of an AST. Although, this SRP section is written primarily for the review of the application for the initial
