低放射性废液输送管网系统改造工程设计研究

Study on Engineering Design for Reconstruction of Low-Level Liquid Radwaste Draining Systems

我国早期建设的核设施低放射性废液输送管网系统普遍存在安全隐患,需进行更新改造。本文通过系统现状分析,论述了更新改造设计原则与研究重点,结合工程实例,对老厂区低放射性管网系统更新改造的技术难点进行了研究和分析,确定了设计方案。

Potential safety hazards occur on the low-level liquid radwaste draining systems of nuclear facilities constructed during 60~70 s of the last century and reconstruction is demanded.By analyzing the present situation of the draining systems,the design principle and important factors for the design of the reconstruction engineering are discussed.Taking the reconstruction of the low-level radwaste draining system in the old building area as an example,the technical difficulties are studied and analyzed,and a design scheme is developed.
