Abstract
The invention, which belongs to the technology field of the safety equipment of the nuclear power station, discloses a non-passive water level control and residual heat removal device of a spent fuel storage pool. The device provided in the invention comprises two loops that include a float filling and drainage loop and a natural circulating and cooling loop. a water level of a spent fuel pool is controlled by a float; simultaneously, a cooling function of water in a spent fuel storage pool can be realized by depending on non-passive natural circulation. The two loops complement each other, so that a water level and a cooling process of the spent fuel pool can be guaranteed together. According to the invention, natural circulation, gravity action, and pressure action and the like simultaneously exist in the device and are in non-passive modes; the implementation and the control are easy; besides, the device has advantages of high reliability, security and stability.
Description
Technical field
The invention belongs to the nuclear plant safety equipment technical field, be specifically related to a kind of non-active irradiated fuel store pool water level control and residual heat removal facility.
Background technology
Accident appears at nuclear power station, station service when forfeiture particularly, cause under the too high or too low situation of the water level in irradiated fuel store pond, and might cause the radioactive water in irradiated fuel store pond excessive or spentnuclear fuel exposed.Thus, spentnuclear fuel pond temperature is too high, and spentnuclear fuel melts.If deal with improperly, might cause the radioactivity diffusion, accident will be worsened.In nuclear power station, the main processing mode of spentnuclear fuel is irradiated fuel store just to be entered the last handling process of spentnuclear fuel in the irradiated fuel store pond at least after 300 days at present.The draining loop of filling in traditional irradiated fuel store pond is made up of A, B two row.Each shows a pump, a heat exchanger, an ion-exchanger and a filtrator.The two shared import and export house stewards of row.Spentnuclear fuel pond after the improvement has kept original design loop, added second kind of non-active draining loop and residual heat removal facility of filling on basis, loop in this design, make it to meet more the nuclear plant safety principle, the irradiated fuel store cell system also just improves more and is reliable.
Summary of the invention
The purpose of this invention is to provide a kind of non-active irradiated fuel store pool water level control and residual heat removal facility.
A kind of non-active irradiated fuel store pool water level control and residual heat removal facility, comprise A, B two row, whenever show a pump, a heat exchanger, an ion-exchanger and a filtrator, the two shared import and export house stewards of row comprise that also float fills draining loop and Natural Circulation cooling circuit.
Described float fills the draining loop and is made of boracic pond 1, rubber valve 2, hinge 3, lever 4, retaining valve 5, float 6, irradiated fuel store pond 9, filling valve 11, vent valve 12; Boracic pond 1 places 9 tops, irradiated fuel store pond, float 6 places irradiated fuel store pond 9, float 6 tops are provided with rubber valve 2 and communicate with 1 below, boracic pond, retaining valve 5 links to each other with float 6 by lever 4, lever 4 supports by hinge 3, and filling valve 11 and vent valve 12 are separately positioned on 1 above and below, boracic pond.
Described Natural Circulation cooling circuit is made of heat interchanger 7, tedge 8, irradiated fuel store pond 9, water aspirator 10; Water aspirator 10 tops connect tedge 8, place the liquid in irradiated fuel store pond 9, and heat interchanger 7 places outside the irradiated fuel store pond 9, and an end connects tedge 8, and the external pipe of the other end communicates with liquid in the irradiated fuel store pond 9.
Beneficial effect of the present invention: the present invention has realized the control of Nuclear Power Station's Exhausted Fuels water level in water pool, finish the refrigerating function in spentnuclear fuel pond simultaneously, it is excessive or spentnuclear fuel pond temperature is too high to have reduced the irradiated fuel store pond radioactive water that may cause, the danger that spentnuclear fuel melts.
Description of drawings
Fig. 1 fills draining loop and Natural Circulation cooling circuit synoptic diagram for float of the present invention;
Among the figure, 1-boracic pond, 2-rubber valve, 3-hinge, 4-lever, 5-retaining valve, 6-float, 7-heat interchanger, 8-tedge, 9-irradiated fuel store pond, 10-water aspirator, 11-filling valve, 12-vent valve.
Embodiment
The present invention will be further described below by the drawings and specific embodiments.
A kind of non-active irradiated fuel store pool water level control and residual heat removal facility, comprise A, B two row, whenever show a pump, a heat exchanger, an ion-exchanger and a filtrator, the two shared import and export house stewards of row comprise that also float fills draining loop and Natural Circulation cooling circuit.
The present embodiment float fills draining loop and Natural Circulation cooling circuit synoptic diagram as shown in Figure 1, and float fills the draining loop and is made of boracic pond 1, rubber valve 2, hinge 3, lever 4, retaining valve 5, float 6, irradiated fuel store pond 9, filling valve 11, vent valve 12; Boracic pond 1 places 9 tops, irradiated fuel store pond, float 6 places irradiated fuel store pond 9, float 6 tops are provided with rubber valve 2 and communicate with 1 below, boracic pond, retaining valve 5 links to each other with float 6 by lever 4, lever 4 supports by hinge 3, and filling valve 11 and vent valve 12 are separately positioned on 1 above and below, boracic pond; The Natural Circulation cooling circuit is made of heat interchanger 7, tedge 8, irradiated fuel store pond 9, water aspirator 10; Water aspirator 10 tops connect tedge 8, place the liquid in irradiated fuel store pond 9, and heat interchanger 7 places outside the irradiated fuel store pond 9, and an end connects tedge 8, and the external pipe of the other end communicates with liquid in the irradiated fuel store pond 9.
Float 6 is walked downwards when water level is low, and can drive rubber valve 2 and walk downwards this moment, and the water in the boracic pond 1 is flowed in the irradiated fuel store pond 9; When water level was higher, float 6 can move up, and blocked the outlet in boracic pond thereby drive rubber valve 2 moves up.Meanwhile, retaining valve 5 can be opened under the effect of lever 4, thereby realizes the draining in irradiated fuel store pond 9.Lever 4 supports by hinge 3.Can realize the level that the water level in irradiated fuel store pond 9 remains on to be needed by above process.
Under the normal operating condition, water in the irradiated fuel store pond 9 still relies on original cooling system to cool off, in case break down, when the normal cooling system in irradiated fuel store pond 9 can not be worked, particularly when heat is very big, can rely on non-active single-phase Natural Circulation to finish the refrigerating function in irradiated fuel store pond 9, its mechanism is, under the water-filled situation in whole loop, the ascent stage 8 on water aspirator 10 tops is that the density of the interior water of hot arc of Natural Circulation reduces, make progress away and finished cooling procedure through heat interchange behind the arrival heat interchanger 7, the density of water increases, and flows back to irradiated fuel store pond 9 downwards.
