REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB) Secondary - None I. AREAS OF REVIEW The main condenser (MC) system is designed to condense and deaerate the exhaust steam from the main turbine and provide a heat sink for the turbine bypass system. 1. The PSB reviews the performance requirements of the main condenser for both direct and indirect cycle plants during all operating conditions. Emphasis will be placed on the review of direct cycle facilities with regard to the prevention of loss of vacuum, corrosion and/or erosion, and hydrogen buildup. 2. The PSB reviews the design of the MC system with respect to the following: a. The means to detect, control and facilitate correction of the leakage of cooling water into the condensate; to detect radioactive leakage into or out of the system; and to preclude accidental releases of radioactive materials to the environment in amounts in excess of established limits. b. Instrumentation and control features that determine and verify that the MC is operating in a correct mode. C. The means provided to deal with flooding from a complete failure of the MC and to preclude damage to safety-related equipment from the flooding. d. The capability of the MC to withstand the blowdown effects of steam from the turbine bypass system. In the review of the Main Condenser, the PSB will coordinate other branch evalua- tions that interface with the overall review of the system as follows. The 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 Commssions policy to Inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission's regulations and compliance with them Is not
