Study of Estimating Method for Residual Radioactive on Decommissioning Nuclear Establishment

Deptment of Nuclear Science & System Engineering, Shanghai Jiaotong University, 200030, China

摘要: 源项调查是核设施退役的一个重要环节。本文运用辐射探测技术获得的反应堆控制棒辐射场实测数据,结合照射量率计算的基本公式,建立了一种简捷、实用、可靠的放射性存留量估算方法；并以一组控制棒照射量率的实测数据为例,对其放射性存留量进行了估算,对该方法的主要误差来源及应注意的问题进行了探讨。

Abstract: The source term investigation is one of the important processes during decommissioning. This paper presents a general method of estimating the residual radioactivity doses of components or structures in nuclear reactors based on the radiation doses data. Taking the measured radiation dose of control rods as an example, the residual radioactivity dose is calculated. The limits regarding the method and some issues were discussed also.
