MPWR) REVIEW RESPONSIBILITIES Primary - Accident Evaluation Branch (AEB) Secondary - Reactor Systems Branch (RSB) I. AREAS OF REVIEW This SRP section covers the review of the radiological consequences of a postulated steam generator tube failurf accident at a pressurized water reactor (PWR) facility and includes the following: (1) A review of the sequence of events and plant procedures for recovery from the accident, as described by the applicant, with and without offsite power available, to assure that the most severe case of radioactive releases has been considered. (2) A review of the models and assumptions used by the applicant for the calculation of the thyroid and whole-body doses for the postulated accident. (3) An independent calculation by the staff of the thyroid and whole-body doses for the accident (4) A comparison of the doses calculated by the applicant and by the staff with the appropriate exposure guidelines, as stated in subsection II below, and (5) An evaluation of the technical specifications on the primary and secondary coolant iodine activity concentration. The review includes two cases for the reactor coolant iodine concentration corresponding to (1) a preaccident iodine spike and (2) a concurrent iodine spike. The potential for fuel failures resulting from the postulated accident is routinely evaluated by the RSB and such information is provided to the AEB as an additional source of iodine activity in the reactor coolant for consideration in the evaluation of the radiological consequences. Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants. These documents are made available to the public as part of the Commission's policy to Inform the nuclear Industry and the general public of regulatory procedures and policies.
