COOLING FACILITY FOR AIR RECIRCULATION SYSTEM OF REACTOR CONTAINMENT VESSEL
原子炉格納容器空気再循環系冷却設備
要約
子炉の格納容器空気再循環系(CAC)とサービス建屋換気系(SBV)の各冷却設備において、冷凍機の総設備容量と台数を低減する。
【構成】CAC側として格納容器9内の雰囲気温度を一定にするために熱除去を行う冷却器への冷水を供給する循環ポンプ1aの1台と冷却器3a~3dにて熱交換された冷水の熱除去を行う冷凍機2aの1台、SBV側として、建屋換気系の熱負荷、及びSBVの熱負荷、更に格納容器内の熱負荷を除去するための冷凍機4a~4cの3台、及び各負荷に冷水を供給する冷水循環ポンプ15a~15cの3台の機器と共通予備としてのCAC冷水循環ポンプ1b、冷凍機2b各1台、通常運転時のCAC内の熱負荷を除去するための流量調節弁17,遮断弁19、戻り弁16と建屋換気系へ冷水を供給するための流量調節弁13、及びCACとSBVの連絡用配管14から構成される。
Abstract:
PURPOSE: To reduce the entire facility capacity and the number of refrigerators in each cooling facility of a containment vessel air recirculation system (CAC) and a service building ventilation system in a reactor.
CONSTITUTION: In order to make atmosphere temperature of the inside of a containment vessel 9 constant, a recirculation pump 1a for supplying cooling water to coolers for performing heat removal and a refrigerator 2d for performing the heat removal of the heat-exchanged cooling water in the coolers 3a-3d are equipped. Three refrigerators 4a-4c for removing heat load of a building ventilation system, SBV, and the inside of the containment vessel as the side of SBV, a CAC cooling water circulation pump 1b and refrigerator 2b as common spare, a flow control valve 17, cutoff valves 19a, 19b and a return valve 16 for removing the heat load of the inside of CAC at the time of normal operation, a flow control valve 13 for supplying the cooling water to a building ventilation system 13 and tubing 14 for connecting CAC and SBV are constituted.
