摘要

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。

Abstract

Background

The fluoride salt-cooled pebble bed re

actor which has not yet been built so far is a new international research reactor

so the selection of similar reactors with operation experience as benchmark is one important part of the applicability analysis for its reactor core nuclear design software.

Purpose:

This study aims to determine quantitatively the rationality of the 10 MW high-temperature gas-cooled test reactor (HTR-10) and the Molten Salt Reactor Experiment (MSRE) to be the benchmarks for the fluoride salt-cooled pebble bed reactor.

Methods:

The similarities of the fluoride salt-cooled pebble bed reactor with HTR-10 and MSRE were analyzed with the adoption of the similarity analysis software that is often used.

Results:

The results show that the fluoride salt-cooled pebble bed reactor and MSRE have a high similarity because they have the close spectrum peak energies and almost the same elements in core. The fluoride salt-cooled pebble bed reactor and HTR-10 have the different coolant and more differences in spectrum peak energies

hence the low similarity.

Conclusion:

MSRE is an ideal benchmark of the reactor core nuclear design software for the fluoride salt-cooled pebble bed reactor.
