REVIEW RESPONSIBILITIES Primary - Chemical Engineering Branch (CMEB) Secondary - None 1. AREAS OF REVIEW The condensate cleanup system (CCS) removes dissolved and suspended impurities due to corrosion from condenser or steam generator leaks that could be introduced into the CCS by carryover from the main steam system. The CCS is not required for safe shutdown or mitigation of postulated accidents, but is important in maintaining the primary coolant quality in direct cycle plants or the secondary coolant quality in indirect cycle plants. The CMEB reviews the CCS from the supply point downstream of the condensate pumps to the discharge point upstream of the feedwater heaters, and also to the interfaces with the effluent treatment systems. 1. The CMEB assures that the CCS is reviewed to verify that the system provides feedwater to the reactor for direct cycle plants or to steam generators for indirect cycle plants that meets water purity requirements. Condensers are reviewed to determine that proper design measures are taken to assure that the chloride concentration and other contaminant concentrations are limited to allowable values until the condensate and feedwater systems can be isolated in the event of condenser tube leaks. 2. A review is performed by CMEB to determine that the quality of the water supplied to the reactor for direct cycle plants (SRP Section 5.4.8), and to the steam generators for indirect cycle plants (BTP MTEB 5-3), meets water purity requirements. CMEB reviews are performed to verify the compatibility of the materials of construction with the service conditions. CMEB will coordinate the evaluations of other branches that interface with the overall review of the condensate cleanup system as follows: 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.
