IPC: G21D1/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for periodic checking by making on-line maintenance of a reactor auxiliary component sea water cooling system (RSW) and an emergency diesel generator(D/G) possible. SOLUTION: A high pressure core cooling system (HPCF8, RCIC6) is constituted of 3 divisions, a low pressure core cooling system (LPFL) 1 and a residual heat removal system (RHR) 2 are constituted of 4 divisions, the piping of a reactor auxiliary component cooling system (RCW) is constituted of 2 loops, and two or more reactor auxiliary component cooling system pumps are provided in one loop. A reactor auxiliary component sea water cooling system (RSW) is constituted with 2 or more loops for one loop, i.e., 4 loops in total, and an emergency power source (D/G5, etc.), for supplying electricity to them is constituted of 4 divisions. Owing to the increase of RHR from 2 systems to 4 systems by this constitution, the possibility of reactor cooling failure during plant operation is reduced.  Also owing to the increase of D/G5 from 3 to 4, the probability of core damage due to loss of power is reduced.
