摘要: 钍铀燃料循环核数据的精度和可靠性直接关系着钍基熔盐堆的安全性和经济性。目前大多数核数据都是基于铀钚燃料循环进行开发,若直接用在钍基熔盐堆上将会出现核设计不确定度较高的问题。为了提高钍基熔盐堆物理设计所需核数据的适用性,中国科学院上海应用物理研究所自行设计并建造了紧凑型的15 MeV电子加速器驱动的白光中子源(Photoneutron Source,PNS),用于开展钍铀燃料循环核数据的实验测量。该装置已通过技术验收,并进行了一系列关键核素的核数据测量,检验了现用核数据的可靠性,为相关核素的核数据评价与改进提供了基础实验数据。Abstract: The accuracy and reliability of Th-U fuel cycle nuclear data have an important impact on the safety and economy of thorium based molten salt reactor. However, the existing nuclear data, which are developed based on U-Pu fuel cycle, will arise high uncertainty in the nuclear design of thorium molten salt reactor. In order to improve the applicability of nuclear data for the physical design of thorium molten salt reactor, a compact photoneutron source (PNS) driven by a 15 MeV electron LINAC was designed and built up by Shanghai Institute of Applied Physics of CAS for the measurement of Th-U fuel cycle nuclear data. The PNS has passed the technical acceptance, and carried out a series of nuclear data measurement for key nuclides, which are used for verifying the reliability of existing nuclear data and providing the basic experimental data for the evaluation and improvement of nuclear data.

Abstract: The accuracy and reliability of Th-U fuel cycle nuclear data have an important impact on the safety and economy of thorium based molten salt reactor. However, the existing nuclear data, which are developed based on U-Pu fuel cycle, will arise high uncertainty in the nuclear design of thorium molten salt reactor. In order to improve the applicability of nuclear data for the physical design of thorium molten salt reactor, a compact photoneutron source (PNS) driven by a 15 MeV electron LINAC was designed and built up by Shanghai Institute of Applied Physics of CAS for the measurement of Th-U fuel cycle nuclear data. The PNS has passed the technical acceptance, and carried out a series of nuclear data measurement for key nuclides, which are used for verifying the reliability of existing nuclear data and providing the basic experimental data for the evaluation and improvement of nuclear data.
