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...
