plant a nuclear reactor including means for injecting additional coolant in the reactor coolant

摘要

a nuclear reactor in pressurized water takes his removal plant residual heat to supplement water in the reactor coolant circuit from a water supply to rifornimentor in the containment during depressurization and stages of emergency cooling by gravity feed passive reservoir storage of water filling and theagamento of the containment building.when depressurization start due to a loss of western or controllable.the system or installation to remove residual heat is activated manually and prevents flooding of the containment when such action is not necessary.the operation of the system or passive cooling system is not compromised.a tank for storage of water of high pressure is connected to the integration circuit reactor coolant and refrigerant of integration or backup to the pressure of funzionamento reactor. the system or installation of depressurization stage vent circuit of coolant to the containment, thus reducing the supply of coolant to integration.the level of coolant of integration can be detected to trigger the initiation of subsequent depressurization conduits.the residual heat removal pumps to move water from the storage tank to supply water in the refrigerant circuit when the circuit of the coolant is depressurizzator, by preventing to reach the stage of the final depressurization unless the level of coolant of integration does not continue to decrease.the residual heat removal system may be connected in a closed loop, or ring with the tank supply water supplies or reload a path removalauxiliary heat.
