氟盐冷却球床堆是当前国际上一种新的研究堆型,尚无已经建造完成的反应堆,因此,选择相似且具有运行经验的反应堆作为基准题有助于堆芯核设计软件适用性分析。利用国际上常采用的相似性分析软件,可对熔盐实验堆(Molten Salt Reactor Experiment,MSRE)及10 MW高温气冷堆(10 MW high-temperature gas-cooled test reactor,HTR-10)与氟盐冷却球床堆的相似性进行分析,定量判断它们作为基准题的合理性。分析结果表明,MSRE和氟盐冷却球床堆的能谱峰位能量接近且堆内元素种类相近,二者相似程度较高;常温临界HTR-10和氟盐冷却球床堆冷却剂不同,且能谱峰位能量差异较大,二者相似程度较低。因此,MSRE是氟盐冷却球床堆中子物理设计软件较理想的基准题。
Fluoride salt cooling bed reactor is currently a new type of research reactor in the world, there is no reactor has been completed, so the choice of similar operating experience with the reactor as a benchmark to help core design software applicability analysis . The similarity analysis software commonly used in the world can simulate the Molten Salt Reactor Experiment (MSRE) and 10 MW high-temperature gas-cooled test reactor (HTR-10) with fluorine The similarity of salt-cooled ball beds is analyzed and its rationality is quantitatively judged. The results show that the MSE and the fluoride salt cooling ball bed reactor energy peak energy is close to the same type of elements within the reactor, the two similarities are higher; room temperature critical HTR-10 and fluoride salt cooling ball bed reactor coolant and The energy difference of the peak of the energy spectrum is quite big, the two are less similar. Therefore, MSRE is a better benchmarks for fluoride salt-cooled ball bed reactor neutron physics design software.
