2) the hold-up tank suspender breaks off relations loose jar and operates
After hold-up tank lifting elevator unit 24 driving hold-up tank suspenders 3 winched to assigned address with spent fuel storage tank 5, the electric pushrod 310 of operation hold-up tank suspender 3 promoted shift fork 314; Drive in the U type groove 38 of turning set connecting rod 315 on slip cap 4 and slide, circumferentially rotate, its 4 inner slidiing pins 39 are changed in the vertical slot in 4 U type grooves 38 of slip cap 34 thereby drive turning set 33; Slip cap 34 is under action of gravity; Relatively adapter sleeve 32 moves down, and makes 4 slidiing pins 39 of turning set 33 move to the last translot position of 4 U type grooves 38 of slip cap 34, operates the electric pushrod 310 of hold-up tank suspender 3 then; Promote shift fork 314 and drive slip in the U type groove 38 of turning set connecting rod 315 on slip cap 34; Circumferentially rotate thereby drive turning set 33, make its 4 inner slidiing pins 39 in 4 U type grooves 38 of slip cap 34, change the translot position over to, carry hold-up tank suspender 3 on the hold-up tank lifting elevator unit 24; Suspension hook 35 is thrown off; Unclamp spent fuel storage tank lifting mouth, and keep the unhook state, until the operation of next cage.
According to complete device of spent fuel storage tank and shielding cover of nuclear power plant of the present invention; Can be with the spentnuclear fuel of pebble bed high temperature reactor discharge; Through the conveyance conduit spent fuel storage tank 5 of packing into, the spent fuel storage tank 5 that will fill spentnuclear fuel is then packed into through ground car 13 and hanging device and is stored in the irradiated fuel store storehouse.When needs move away spent fuel storage tank 5 in depots, can spent fuel storage tank 5 be taken out in depots, transport through the hanging device spentnuclear fuel shielding transfer container of packing into then.The operating process of radome complete equipment is following:
1) charging of spent fuel storage tank 5 and in-stockroom operation
2) outbound of spent fuel storage tank 5 operation
When needs took out spent fuel storage tank 5 in storage vertical shaft, ground car 13 drove the radome complete equipment, well lid overcoat 9 is navigated to the center of storage vertical shaft; Well lid lifting mechanism 6 grasps shielding well lid 8 through well lid gripping apparatus 7, will shield well lid 8 and rise in the well lid overcoat 9, and car 13 drives the radome complete equipment then; Radome cylindrical shell 2 is navigated to the center of storage vertical shaft; Pull base plate 10 is opened, and hold-up tank lifting elevator unit 24 drives hold-up tank suspender 3, and it is transferred in the storage vertical shaft; After grasping the spent fuel storage tank of placing in the vertical shaft 5; Hold-up tank lifting elevator unit 24 drives hold-up tank suspenders 3 and is recovered in the radome cylindrical shell 2 with spent fuel storage tank 5, pull base plate 10 is closed, with spent fuel storage tank 5 let-downs to pull base plate 10; Car 13 drives the radome complete equipment then, and well lid overcoat 9 is navigated to the center of storage vertical shaft, and well lid lifting mechanism 6 resets to the shielding well lid 8 that grasps on the well head of storage vertical shaft through well lid gripping apparatus 7, accomplishes the outbound operation of spent fuel storage tank 5.
3) transfer operation of spent fuel storage tank
Needs with spent fuel storage tank 5 in the depots during to the transhipment of other site; Spent fuel storage tank 5 is taken out in storage vertical shaft, and car 13 drives the radome complete equipment then, navigates on the hold-up tank lifting mouth of operation room; Pull base plate 10 is opened; Hold-up tank lifting elevator unit 24 drives hold-up tank suspenders 3, and hold-up tank 5 is transferred in the spentnuclear fuel shielding transhipment jar under the hold-up tank lifting mouthful, and hold-up tank lifting elevator unit 24 drives hold-up tank suspenders 3 and is recovered in the radome cylindrical shell 2 then; Pull base plate 10 is closed; Accomplish spent fuel storage tank 5 from pack into the operation of spentnuclear fuel shielding transhipment jar of depots, spent fuel storage tank 5 is packed into after the shielding transhipment jar, can transport other site to through automobile.
In charging and transfer process, spent fuel storage tank 5 places in the radome 2, whole spentnuclear fuel feed process and spent fuel storage tank moves and hoisting process in, operating personnel can make an inspection tour and carry out overhaul of the equipments near radome.The wall thickness design of radome has been taken all factors into consideration the radiation dose of spent fuel storage tank, and the radiation subregion requirement in the factory building.
Spent fuel storage tank 5 adopts the spent fuel storage tank 5 in 15 pairs of radomes of blower fan to carry out forced air cooling in charging and transport process, and hot-air passes through the outer smoke stack emission of spentnuclear fuel factory building to outside atmosphere.
In ground car 13 operational processs, shielding lifting mechanism 12 is mentioned bar shaped shielding 11, and after ground car 13 stopped, in the time of need carrying out other operation, shielding lifting mechanism 12 was put bar shaped shielding 11 and fallen to the ground the radioactivity that shielding possibly spill.
Complete device of spent fuel storage tank and shielding cover of nuclear power plant of the present invention is except having the radiation shield function; Also have the lifting of lifting, the storage vertical shaft well lid of spent fuel storage tank, to types of functionality such as spent fuel storage tank cool off; This device also can be used to operate the spent fuel storage tank in pressurized-water reactor nuclear power plant and other types of nuclear power station through suitably revising.
Above embodiment only is used to explain the present invention; And be not limitation of the present invention; The those of ordinary skill in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
