Condensate polishing at Surry Nuclear Power Station
Condensate polisher system design and operation at the Surry Nuclear Power Station of Virginia Electric and Power Company were evaluated relative to the ability of the polishers to achieve effluent water quality consistent with PWR Steam Generator Owners Group chemistry guidelines. Polishers regenerated employing a conventional process were evaluated during normal plant operation and during periods of simulated condenser inleakage. Polisher effluent quality was consistent with requirements for PWR steam generator corrosion minimization with minor exceptions, i.e., sodium and sulfate leakage immediately following initiation of most service cycles. Resin aging and incomplete separation of anion and cation resin during the regeneration process were the major reasons for non-optimum polisher performance.
