针对我国国产反应堆严重事故分析程序的发展需要,西安交通大学开发了一体化严重事故分析程序(modular severe accident analysis program,MOSAP).为了验证 MOSAP程序在再淹没期间相关模型的合理性和准确性,以QUENCH-06实验为例,利用MOSAP程序对实验进行建模,并将MOSAP程序的计算结果与实验结果以及国际通用程序的计算结果进行了对比.结果表明,对于包壳轴向温度、包壳氧化层厚度和氢气产量,MOSAP程序计算结果与实验值和国际通用程序计算结果符合良好.在计算包壳轴向温度和氧化层厚度方面,MOSAP程序计算结果优于国际通用程序计算结果.文中结论对MOSAP程序堆内模块验证和整个模块的验证具有一定的参考意义.
Verification and analysis of modular severe accident analysis program
For the development of the domestic reactor severe accident analysis program,Xi'an Jiaotong University developed an integrated severe accident analysis program called MOSAP(modular severe accident analysis program).In order to verify the rationality and accuracy of the MOSAP program model during reflooding process,taking the QUENCH-06 experiment as an example,we used MOSAP program to model the experiment,and compared the calculation result of MOSAP program with the experimental and calculation results of international standard program.The results show that the result calculated by MOSAP are in good agreement with the experimental results and international standard program output results for the axial temperature of cladding,the thickness of cladding oxide layer and the hydrogen production.The results calculated by MOSAP are better than those calculated by international standard program in the calculation of the axial temperature and the thickness of cladding oxide layer.The conclusions in this study are of certain reference significance to the verification of both the internal module and the entire module of the MOSAP program.
