Description
Technical field
The present invention relates to a kind of passive safety injection system, in particular to a kind of passive safety injection system for nuclear power station.
Background technology
The nuclear power of safety is the clean energy resource of a kind of high-energy source density, to preserving the ecological environment, readjust the energy structure and ensure that energy security has important effect.But once safety problem occurs in nuclear power station, then staff, nearby residents and ecological environment etc. can be brought huge threat.For this nuclear plant safety problem be people apply nuclear power time must the problem that considers of emphasis.Nuclear power station tends to use non-passive safety technical finesse accident at present.So-called non-passive safety technology refers to utilize natural agent to complete various refrigerating function in the case of having an accident, and the driving force etc. that wherein natural agent can be produced by gravity, pressure accumulation gas pressure, Natural Circulation produces, it is not necessary to pump and external power source.Therefore, while improve nuclear plant safety reliability, it is greatly simplified the security system of nuclear power station of knowing clearly.
The nuclear power station of prior art includes the reactor core waste heat that primary heat transport system and the reactor core emergency cooling system reactor core emergency cooling system communicated therewith produce for taking away reactor core remnants in primary heat transport system to fission when having an accident.
Fig. 1 shows the primary heat transport system of current passive nuclear power station.nullAs shown in Figure 1，The primary heat transport system of current passive nuclear power station includes steam generator 6、U-tube 5、Primary heat transport system cold section 3、Primary heat transport system hot arc 4、Main pump 9、Reactor pressure vessel 2、It is positioned at the reactor core 1 of reactor pressure vessel 2、Surge line piping 10 and manostat 11，During wherein U-tube 5 is arranged on steam generator 6，The U-tube port of export is pooled to the cold chamber compartment 7 of steam generator bottom，Cold chamber compartment 7 is connected for cold with primary heat transport system section 3 by main pump 9，Primary heat transport system connects with reactor pressure vessel 2 for cold section 3，Reactor pressure vessel 2 also connects with primary heat transport system hot arc 4，Primary heat transport system hot arc 4 is connected with manostat 11 by Surge line piping 10 and passes through the hot chamber compartment 8 of steam generator bottom and connects with the arrival end of U-tube 5，Coolant enters reactor pressure vessel 2 for cold section 3 by primary heat transport system，Arrive the entrance of reactor core 1，The Q-value that reactor core produces is taken away when flowing through reactor core 1，Heated coolant (such as temperature is of about 321 DEG C) flows through primary heat transport system hot arc 4，Arrive the hot chamber compartment 8 of steam generator bottom and enter the arrival end of U-tube 5，Coolant in transferring heat to steam generator 6 by U-tube 5 and outside U-tube 5，Coolant temperature in U-tube 5 reduces (such as coolant temperature is 280 DEG C) and collects in steam generator bottom cold chamber compartment 7 by the port of export of U-tube，In cold chamber compartment, the coolant of 7 pumps into primary heat transport system cold section 3 by main pump 9，Turn again to reactor pressure vessel 2，Form the enclosed cooling circulation of primary heat transport system.In Fig. 1, arrow F1 is the coolant flow direction that temperature is relatively low, and arrow F2 is that the coolant that temperature is higher flows to.
For the pressure of stable primary heat transport system, primary heat transport system hot arc 4 is connected with manostat 11 by Surge line piping 10, is saturated solution and saturated vapor (for example, cooling water saturation liquid and saturated vapor), meets the voltage stabilizing requirement of primary heat transport system in manostat 11.Manostat 11 for maintaining properly functioning high pressure conditions (such as about 15.5MPa) by the pressure of primary heat transport system so that during reactor core 1 reaction in normal operation, the coolant in reactor pressure vessel 2 does not haves boiling.The cooling water of reacted heap reactor core 1 heating is when flowing through U-tube 5, cooling water in transferring heat to steam generator 6 and outside U-tube 5, the cooling water evaporation in steam generator 6 is made to form steam, in steam generator 6, steam passes through main steam pipe 12, it is fed to steam wheel pump (not shown in figure 1) by normally opened main steam isolation valve 13, drive the generating of steam wheel pump, thus the heat that reactor core produces is changed into electric energy.
In the case of nuclear power station generation is fully powered-off, owing to main steam isolation valve 13 is closed, the steam that saturation water evaporation in the secondary side of steam generator (space in steam generator 6 and outside U-tube 5) produces cannot flow to steam wheel pump (not shown in figure 1), and the secondary side of steam generator cannot utilize normal operation mode to take away reactor core remnants and fission the reactor core waste heat produced.Now, first passive nuclear power station relies on the Natural Circulation of primary heat transport system, a part of reactor core waste heat is passed to steam generator secondary side by the U-shaped heat-transfer pipe in steam generator, the saturated cooling water having in making steam generator secondary side constantly absorbs heat evaporation, in causing steam generator secondary side, pressure raises, when pressure is increased to the unlatching pressure of steam generator secondary side relief valve setting (such as 7.8MPa), steam generator secondary side relief valve is opened, high steam is discharged in containment, to steam generator secondary side pressure release, when pressure drop is as little as when the closing presure that steam generator secondary side relief valve sets (such as 7.6MPa), steam generator secondary side relief valve cuts out.After steam generator secondary side relief valve cuts out, steam generator secondary side raises again owing to the lasting heat exchange of U-tube absorbs its internal pressure of reactor core waste heat, the open and close and so forth of steam generator secondary side relief valve, discharge steam, until steam generator secondary side liquid level is reduced to the low liquid level that steam generator secondary side sets.Now, if reactor core waste heat cannot be continued to take away, then will have an accident.
Thus, need to provide a kind of passive safety injection system for nuclear power station, when steam generator secondary side liquid level is reduced to low liquid level, it is carried out reliable passive moisturizing, steam generator secondary side is made persistently to set out reactor core waste heat, reduce the risk that reactor core is exposed, response time after prolongation accident, improve the safety allowance of nuclear power station.
