摘要

钍基熔盐堆（Thorium-based Molten Salt Reactor，TMSR）作为一种新的堆型，具有独特的安全与运行特性。研究其热工水力特性，对其进行瞬态分析，将有助于深刻理解该反应堆。本文介绍了1 GW固态熔盐堆的堆芯设计方案，并描述了用于瞬态分析的详细程序结构。其中，利用RELAP5对其热工水力模型进行模拟；利用Simulink对其控制系统模型进行模拟。通过预期运行瞬态，例如功率降低、堆芯反应性引入、二回路温度变化等工况显示了其运行特性，并验证了控制系统可以使反应堆达到安全稳定状态，而不触发保护系统动作。

Abstract

Background

As a new type of reactor

thorium-based molten salt reactor (TMSR) has unique safety and operation characteristics. Its thermal-hydraulic features are enormously different from other reactors

thus worth doing transient analysis.

Purpose

This study aims at disturbed transient analysis of TMSR for fundamental comprehension of its safety and operation characteristics.

Methods

The structure and design scheme of the core of 1-GW solid fuel thorium-based molten salt reactor (TMSR-SF) have been presented. Structural emulation platform for transient analysis is proposed with the thermo-hydraulic model being developed on the basis of RELAP5

and the control system model being constructed by using the MATLAB/Simulink software.

Results

The results of emulation test for operational transient

such as rapid power reduction

step load reducing

linear load reducing and temperature of secondary loop inlet reducing show that the reactor control system is effective to bring the reactor into a safe and steady state without actuation of reactor protection system.

Conclusion

Analysis results show that the design satisfied the requirements of 1-GW TMSR-SF operational transient. It also indicates that the platform can perfectly simulate the variable power transient conditions.
