摘要

建立一套放射性废物就地有效的测量办法是实现废物科学化和最小化管理的重要措施之一。核设施的运行及退役都会产生放射性废物，放射性废物中的不同核素给公众和环境会带来不同的危害。对不同的放射性核素加以区分测量可以对废物进行更为合理化的分类管理，就地γ分析测量技术和桶装α废物测量技术已日渐成熟，但是对放射性废物中纯β核素就地直接测量仍非常困难。以中国原子能科学研究院

Sr污染物料为研究对象，对中国原子能科学研究院现有固体废物处理示范设施设计的技术路线进行优化设计，提出在线测量废物中

Sr-

Y放射性的技术方法，尽可能将一部分放射性废物分开和优化管理，实现废物分类和豁免废物的进一步筛选。

Abstract

Background:

Operation and decommissioning of nuclear facilities will produce radioactive waste

and different radionuclides in the waste will bring different hazards to the public and the environment. The waste would be sorted more reasonably by distinguishing different radionuclides. Yet it is still very difficult to measure directly the pure β radioactive waste

in situ

though

in situ

γ-analytical-and α-waste-barrel measurement techniques have become more sophisticated.

Purpose:

The aim is to propose a scientific technique to sort the radioactive waste

in situ

Methods:

This study focused on the

Sr-contaminated material in China Institute of Atomic Energy and optimized the design of the existing solid waste disposal facilities.

Results:

A novel technique to measure the radioactive waste

Sr-

Y online was proposed

trying to sort the radioactive waste as optimally as possible to realize further separation of exemption waste.

Conclusion:

Theoretically

the exemption waste can be further sorted

and it can guide the design of radioactive waste disposal system.
