Dynamic valve and non-return valve.
The outlet line of two Reactor cavity flooding cooling pumps 3 respectively through after containment isolating valve run through containment 5, Ran Houhe
And be connected with the main pipe of described passive injection pipeline for a main pipe.When material-changing water tank connects low pressure safety injection pump, heap
The inlet tube of chamber water filling cooling pump is connected respectively with the inlet tube of two row low pressure safety injection pumps, to reduce the number of containment penetration
Amount, from built-in（Or it is external）Material-changing water tank is fetched water.The inlet tube of Reactor cavity flooding cooling pump 3 simultaneously with the outer fire water supply of containment
System 6 is connected.
Described passive Reactor cavity flooding case is the reinforced concrete structure of closing, and is provided with stainless steel lining.System
The material of pipeline and pipe fitting is austenitic stainless steel.
After it there is reactor core damage accident, core exit temperature receives the report for police service when reaching 650 DEG C, needs CIS systems to put into
When, first start CIS system active parts, start in two Reactor cavity flooding cooling pumps, from the built-in of bottom（Or it is external）
Material-changing water tank is fetched water, and forms lasting heap chamber injection cooling.Built-in（Or it is external）When material-changing water tank water level is temporarily unavailable, then
It is connected with the fire water pipeline in containment building by temporary takeover, as the cooling water source of CIS systems.When the built-in water that reloads
When case recovers to use, can will disconnect with the connection of fire protection pipeline, then recover to use the water source in material-changing water tank.

Wear pressure vessel.As the time progress for alleviating accident, fused mass heat release are gradually lowered, required cooling water inflow is also gradually reduced,
Passive high water tank constantly declines, using the teaching of the invention it is possible to provide cooling water flow be also gradually lowered, be to meet cooling water flow and heap
The requirement of Coolant-Level in chamber, it may be necessary to provide extra moisturizing for water tank.After due to there is major accident, the non-energy of containment
Dynamic heat derives system（PCS）Also will start and heat derives containment is passed to into ultimate heat sink air, carry out decrease temperature and pressure, PCS
The structure of system can be found in Chinese patent application 201210090809.9.At the same time, pcs system is by the steaming in containment air
After vapour condensation, by gravity it is passive flow downward collection to passive along the wall of pcs system containment inside heat exchanger
Reactor cavity flooding case, can be the passive offer moisturizing of water tank in the case of station blackout.Simultaneously maintenance personal should recover CIS
System active part and spray system, so as to formed the long-term cooling of reactor core fused mass and the long-term step-down of environment in containment and
Cooling.After the active part of CIS systems recovers, continued by cooling water injection heap chamber, even if by electric power storage by Reactor cavity flooding cooling pump
Battery-powered motor-driven valve cannot be closed, but non-return valve can ensure that passive Reactor cavity flooding case will not be contaminated.
When major accident is eased, operations staff judge can not occur again lower head of pressure vessel failure it is dangerous when,
By operations staff the said equipment is closed and stopped transport.
Embodiment 2
