Embodiment Construction

[0013] Taking a shell-type low-temperature heating reactor with a thermal power of 245MW for seawater desalination as an example, and referring to the accompanying drawing 1, the passive multifunctional pool-type voltage stabilizing system for a nuclear reactor of the present invention will be described in detail.

[0014] Reactor 1 is a shell-type structure that uses stainless steel containers to contain and seal the core, related components and coolant. The whole reactor 1 is placed below the ground level, and is supported on the steps of the pile pit by a support ring welded on the cylinder in the middle of the reactor vessel. The elevation of the upper surface of the reactor core is -9.0m, and the elevation of the refueling operation platform of the reactor building is +4.5m. The reactor coolant runs in a forced circulation mode through the main pump 4, the heat of the reactor core is exported from the reactor coolant system, and the heat is transferred to the secondary ci...

Abstract

The invention discloses a non-active multi-functional ponded stabilivolt system of atomic reactor, which comprises the following parts: high-pressure pond, air cavity on the interior of high-pressure pond, level measuring channel made of concrete structure in the air cavity, wherein the injecting pipe is set on the bottom of high-pressure pond to connect the reacting pile inlet cavity with stop valve on the injecting pipe; the fluctuating pipe is set on the bottom of the high-pressure pond to connect the main pump inlet; the rising pipe is set in the middle of the high-pressure pond to connect the reacting pile output cavity with pneumatic separating valve on the rising pipe; the small-flow circulating pipeline is set on the rising pipe between pneumatic separating valve and reacting pile output cavity, which connects the main pump inlet pipe. The invention improves the safety of reacting pile, which reduces the building and operating cost greatly with wide applying prospect.

Description

technical field [0001] The invention relates to a voltage stabilizing system of a light water reactor, in particular to a passive multifunctional pool type voltage stabilizing system of a nuclear reactor. Background technique [0002] Common nuclear reactor coolant pressure stabilization systems are high-temperature and high-pressure systems. The principle of voltage stabilization is to rely on active electric heaters to boost the pressure and multi-stage safety valves and pressure relief valves to release the pressure to the pressure relief box. Voltage function, must rely on 1E level power supply. In the event of a loss of reactor coolant (LOAC) accident, the water in the pressurizer will vaporize rapidly due to the loss of pressure in the main system, making it impossible to replenish the amount of coolant to the reactor. The special safety injection system must be quickly activated within the specified time. [0003] The coolant system of the low-temperature pool-shell ...
