摘要

本研究旨在利用材料吸引力（attraction）提供一种新的合理的物理保护（PP）设计方法，并利用该方法为具有加速器驱动系统（ads循环）的超铀燃料循环场地设计合理的PP系统。以混合氧化物（MOX）燃料的普通沸水堆（BWR）场址PP系统为例，对新方法进行了验证。因此，澄清了ADS循环场地内项目的最高总体吸引力低于沸水堆场地内的MOX燃料组件，后者被确定为需要内部区域的第一类。ADS循环场地的PP设计要求等级被确定为第二类，不需要内部面积，而ADS循环场地如果采用常规方法进行PP设计，则被划分为第一类。

Rational physical protection design of transuranium fuel cycle site with accelerator-driven system by using material attractiveness

This study aims to provide a new rational physical protection (PP) design method by using material attractiveness (Attractiveness) and to design a rational PP system for a site of the transuranium fuel cycle with accelerator-drive systems (ADSs cycle) using the new method. The PP system of the general boiling water reactor (BWR) site with mixed oxide (MOX) fuel was designed as a reference to validate the new method. As the result, it was clarified that the highest overall Attractiveness of the items within the ADS cycle site was lower than that of the MOX fuel assembly within the BWR site which was determined to be Category I requiring the inner area. The PP design requirement level of the ADS cycle site was determined to be Category II, which does not require the inner area, while the ADS cycle site would have been classified as Category I if the PP design had been conducted using the conventional method.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
