General Guidance INTRODUCTION This chapter of the Standard Review Plan (SRP) identifies the roles and responsibilities of organizations in the U.S. Nuclear Regulatory Commission (NRC) that participatein risk-informed reviews of licensees' proposals for changes to the licensing basis (LB)1 of nu•lear power plants. The SRP identifies the types of information that may be used in fulfilling an organization's responsibilities and provides general guidance on how the information from a probabilistic risk assessment (PRA) can be combined with other pertinent information in the process of making a regulatory decision. The guidance in this document is a logical extension of current NRC policy on the use of PRA in regulatory activities which is documented in the Commission's PRA policy statement and implementation plan (Refs. 1-3). In developing this SRP chapter, the staff considered the NRC's guidance on the use of PRA in risk-informed regulatory applications as documented in Regulatory Guide (RG) 1.174 (Ref. 4) as well as the relevant ind ustry guidance documented by the Electric Power Research Institute (EPRI) in its "Probabilistic Safety Assessment (PSA) Applications Guide" 1 These are modifications to a plant's design, operations or other activities that require NRC approval. These modifications could include items surh as exemption requests under 10 CFR 50.11 and license amendments under 10 CFR 50.90. Standard Review plans are prepared for i the guidace of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclme ower ,pants. These documents are made available to the public, as sections of NUREG-0800, as part of the NRC's policy to inform the nuclear industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guidesiothe NRC's regulations, and compliance with them is not required. The standard review plan sections are keyed to the
