Abstract

One of the primary challenges in negotiating treaties related to the control of Nuclear Materials (NM) is the verification process, particularly when dealing with sensitive information. Normally, in this process, the inspector utilizes a suitable measuring system to verify the declared information. The difficulty may arise whenever sensitive information related to the NM should not be released to an inspector. Simultaneously, the NM owner (operator) should remain unaware of the measuring system employed by the inspector to prevent any probable manipulation. To address this issue, a neutral third party is assumed to act as an intermediary, who matches the data declared by the operator with the results obtained by the inspector, without exchanging any information between them. In this work, a Non-Intrusive System (NIS) is proposed and tested to play this role. The system receives data and information from both the operator and the inspector in the form of CAD or Monte Carlo (MC) input files, in addition to the results of measurements performed by the inspector. Then the system performs calculations and combines the results of these calculations with the inspector's measurement result to estimate the mass of the NM. The only information automatically conveyed to the inspector is the final conclusion regarding whether the declared and the estimated masses of NM are matched or not. The proposed NIS concept is tested using samples of NMs, and the results are presented.

用于核查敏感核材料的拟议非侵入式系统
与核材料(NM)管制有关的条约谈判的主要挑战之一是核查过程,特别是在处理敏感信息时。通常情况下,在这一过程中,检查员利用适当的测量系统对申报的信息进行核查。当与核材料有关的敏感信息不应透露给检查员时,就会出现困难。同时,核磁共振所有者(操作者)应不知道检查员使用的测量系统,以防止任何可能的操纵。为解决这一问题,假定由中立的第三方充当中间人,将操作员申报的数据与检查员获得的结果进行比对,但两者之间不交换任何信息。在这项工作中,提出并测试了一种非侵入式系统(NIS)来扮演这一角色。该系统以 CAD 或蒙特卡洛(MC)输入文件的形式接收来自操作员和检测员的数据和信息,此外还接收检测员的测量结果。然后,系统进行计算,并将计算结果与检查员的测量结果相结合,估算出非金属的质量。自动传达给检验员的唯一信息是关于申报质量和估计质量是否匹配的最终结论。我们使用非金属矿物样本对所提出的非金属矿物检测系统概念进行了测试,并展示了测试结果。

期刊介绍: Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
