Atomic energy power plant system

Abstract

The present invention disclosed an atomic power plant system and operational gaming, which comprises a atomic reactor; a steam turbine, using the steam generated in the atomic reactor pressure vessel; a separating removing device for separating and removing the radioactive substance, set in the pressure vessel or the steam passage between the pressure vessel and the steam turbine inlet. Adopting a drier, which is on the surface of tcorrugated plates with an inorganic ion-exchange material stable under a condition in which high-temperature water exist, such as TiO2, for suppressing the radioactive substance transferred from the pressure vessel of the atomic power plant to the steam system.

Description

technical field [0001] The invention relates to a method, equipment and device for reducing radioactive substances transferred to cooling water or separating and removing these substances in radioactive systems such as atomic energy and thermonuclear power plants. Background technique [0002] In nuclear power plants, it is very important to reduce nuclear radiation during operation and periodic inspection. So far, there have been reductions mainly containing Co -60 The concentration of radioactive substances in the reactor water, or the corresponding measures to reduce the radioactivity transferred to the nuclear reactor water system, and the corresponding measures for various materials, water quality control measures, and improvement measures for purifiers. However, until now, no countermeasures have been taken to reduce the radioactivity transferred to the main steam and turbine systems. [0003] Refer below figure 1 and figure 2 , to describe the radiation transfer ...

AI Technical Summary

Problems solved by technology

However, any device cannot avoid the shortcoming of short life, the increase in pressure difference due to the capture of corrosion products or the contamination of organic matter in the turbine system, the filter agent caused by the hydrochemical instability of high temperature water, or the following small hole shape Poor performance due to changes, the change in the shape of the pores is caused by the precipitation of the filter material or the volume expansion caused by corrosion and oxidation

In addition, the current situation is that there is also a problem that the capture capacity is small, and the purification performance decreases with the passage of time, so it cannot be put into practical use (refer to the document "Guidelines for Filters for Power Generation", page 8, Japan Po-ru Co., Ltd., 1997 issued)
