摘要

The fusion neutron source based on Gas Dynamic Trap (GDT) device has the advantages of high neutron flux, large testing space and low construction cost, so it is an ideal solution for high flux fusion volumetric neutron source As a new type of radioactive facility, how to carry out radiation safety management under the current nuclear safety regulatory laws and regulations in China is an important issue that must be addressed before the construction of this facility In this paper, the radiation safety characteristics of GDT fusion neutron source were analyzed and the main radiation terms of GDT fusion neutron source were explored Combined with the existing nuclear safety regulatory laws and regulations in China, the key points of radiation protection and safety management in the process of construction and application of GDT fusion neutron source were put forward It is recommended that the GDT neutron source should be managed as a class I radiological device Prior to operation, radiation safety permit and nuclear material permit should be observed, and special attention should be paid to the safety protection of radiological criteria This study will pay the way for the radiation safety management of the international high flux fusion neutron source ALIANCE project, and also provide the reference for the related nucleus and radiation safety management departments in China Abstract: As fusion energy research enters the engineering stage, there is an urgent need for high-throughput polymer neutron sources to conduct irradiation testing of materials and components. The fusion neutron source based on Gas Dynamic Trap (GDT) device has the advantages of high neutron flux, large testing space, and low construction cost, making it an ideal solution for high-throughput fusion neutron sources. As a new type of radioactive device, under the current legal and regulatory system of nuclear safety in China, how to carry out radiation safety management is a problem that must be clarified before the construction of the device. This article analyzes the radiation safety characteristics of the GDT fusion neutron source, clarifies the main radiation source terms of the GDT fusion neutron source, and combines the existing nuclear safety regulatory laws and regulations in China to propose the key points of radiation protection and safety management during the construction and application process of the GDT fusion neutron source. It is recommended that the GDT neutron source be managed as a Class I radiation device and obtain a radiation safety permit and nuclear material permit before operation, Special attention should be paid to the safety protection of radioactive tritium. This article provides guidance for the radiation safety management of the international high-throughput polymer neutron source ALIANCE, and can also serve as a reference for China's nuclear and radiation safety management departments.

Preliminary study on radiation safety management of Gas Dynamic Trap based D-T fusion volumetric neutron source

The fusion neutron source based on Gas Dynamic Trap (GDT) device has the advantages of high neutron flux, large testing space and low construction cost, so it is an ideal solution for high-flux fusion volumetric neutron source. As a new type of radioactive facility, how to carry out radiation safety management under the current nuclear safety regulatory laws and regulations in China is an important issue that must be addressed before the construction of this facility. In this paper, the radiation safety characteristics of GDT fusion neutron source was analyzed and the main radiation terms of GDT fusion neutron source were expounded. Combined with the existing nuclear safety regulatory laws and regulations in China, the key points of radiation protection and safety management in the process of construction and application of GDT fusion neutron source were put forward. It is recommended that the GDT neutron source should be managed as a class I radiological device. Prior to operation, radiation safety permit and nuclear material permit should be obtained, and special attention should be paid to the safety protection of radioactive tritium. This study will pay the way for the radiation safety management of the international high flux fusion neutron source ALIANCE project, and also provide the reference for the related nuclear and radiation safety management departments in China. 摘要：随着聚变能研宄进入工程化阶段, 迫切需要高通量聚变体中子源开展材料和部件的辐照测试。基于气动磁镜 (Gas Dynamic Trap, GDT) 装置的聚变中子源具有中子通量高、测试空间大、建造成本低等优点, 是高通量聚变体中子源的理想方案。作为一种新型的放射性装置, 在我国现行核安全监管法律法规体系下, 如何对其开展辐射安全管理是在该装置建造之前必须要理清的问题。本文分析了 GDT 聚变体中子源的辐射安全特性, 阐明了 GDT 聚变体中子源的主要辐射源项, 并结合我国现有核安全监管法律法规要求, 提出 GDT 聚变体中子源在建造及应用过程中的辐射防护与安全管理要点, 建议 GDT 中子源作为I类射线装置管理, 运行之前应取得辐射安全许可证和核材料许可证, 特别需要注意对放射性氚的安全防护。本文为国际高通量聚变体中子源 ALIANCE 的辐射安全管理工作提供指导, 同时可供我国的核与辐射安全管理部门参考。
