Lower layer's ring cavity 17 between 1 cylinder 11 and hanging basket 141 is heated by bottom reactor core lower plate 142 into reactor core.
Since hanging basket 141 is stainless steel, 1 cylinder 11 of pressure vessel is low-alloy steel, and inner wall overlaying stainless steel layer is stainless
Steel is bigger than the thermal walking of low-alloy steel, therefore hanging basket 141 can be outwardly against the first water proof ring 3', the second water proof ring when hot
3 ", allow the upper and lower sides of the first water proof ring 3', the second water proof ring 3 " to be distributed to form mutually isolated ring cavity.
It flows through the primary Ioops coolant that reactor core is heated and enters upper layer ring cavity 15 from 141 the second recirculation hole of upper end 143 of hanging basket,
And the second outlet channel 131 through outlet nozzle 13 enters steam generator.
Second entrance of the primary Ioops coolant after heat exchange from 1 outlet nozzle 13 of pressure vessel in a vapor generator
Channel 132 is back to middle level ring cavity 16, then returns to main pump by the first outlet channel 121 of 1 entrance sleeve of pressure vessel, to
Complete the cycle of primary Ioops coolant.
In other embodiments, according to the difference of main equipment internal structure, also can only in main equipment only setting one every
Water ring 3 allows two extensions 312 of 3 liang of relative edges of water proof ring to coordinate respectively with the pipe nozzle of respective side, respectively by two pipe nozzles
Exit passageway, access road isolation, and allow two ring cavities respectively with exit passageway, inlet passage.It also can be only in water proof ring 3
One extension 312 of upper only setting will take over mouth and be separated into two channels with one of pipe nozzle corresponding matching.
Further, in other embodiments, water proof ring 3 is equally applicable on steam generator, is installed to steam generation
Isolation forms channel in steam generator after in device, allows coolant by specific path flows.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
