Heating method and system of surface pool water of pool type reactor

Abstract

The invention discloses a heating method and a system of surface pool water of a pool type reactor, and the method comprises the steps of taking surface water, increasing the pressure, heating, carrying out impurity filtration, water quality purification, monitoring and sampling after taking the surface water and increasing the pressure, heating, increasing the temperature, and injecting into the surface pool water. The system for realizing the heating method comprises a circulating pump (1) and a heating device (5), as well as a mechanical filter (2), an ion exchanger (3), a resin catcher (4) and a monitoring and sampling device, wherein the circulating pump (1), the mechanical filter (2), the ion exchanger (3), the resin catcher (4), the monitoring and sampling device and the heating device (5) are sequentially connected through a pipeline. The invention provides the heating method and the system of the surface pool water of the pool type reactor, which can realize impurity filtration, water quality purification, on-line monitoring and adjustable power.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor engineering, in particular to a method and system for heating surface pool water of a pool reactor. Background technique [0002] In a pool reactor, the core is immersed in the reactor pool. Due to the heating of the core, the highly radioactive water in the lower part of the reactor pool reaches the surface of the pool water through convection, resulting in a higher radioactive dose in the reactor hall. For this problem, the general processing method is to cover the cover plate on the pool water. With the development trend of advanced research reactors, it not only protects the operating environment, but also prevents the highly radioactive pool water from reaching the surface of the reactor pool, reduces the dose in the hall, and limits the exposure dose of operators. The more advanced technology in the prior art is to use the reactor The surface water of the pool is subjected to circul...
