压水堆核电厂辐射控制技术的研究与应用

Abstract

Abstract: This paper introduces the general idea of reducing the radiation field in pressurized water reactor nuclear power plant. Based on a number of field practice experience at home and abroad, some specific optimization and improvement measures are put forward, from radiation source term control for reactor unit, the development and application of various radioactive decontamination technology, radiation shielding design and installation, as well as radiation hot spot removal and management. Reducing radiation field is a kind of system engineering, because each kind of radiation field reduction technology has its unique advantages but also has certain limitations. Therefore it is necessary to combine all kinds of technology strategically according to the characteristics of reactor unit, in order to achieve continuous control and comprehensive treatment of radiation field.

Key words: Radiation, Source term, pH value, Zinc injection, Shielding, Decontamination, Hot spot
