基于蒙特卡罗程序的AP1000反应堆堆芯布置方案的模拟

AP1000是美国西屋公司研发的大型压水反应堆，采用先进的非能动安全系统。AP1000反应堆有两种堆芯燃料布置方案：D19和Adv。结合两种设计方案的优点提出了一种新的堆芯燃料布置方案。利用MCNP6（Monte Carlo N—particle6）程序对D19堆芯和新方案堆芯的首循环进行建模，并主要计算了新堆芯的核设计参数随燃耗的变化。结果表明，新堆芯在首循环寿期内满足AP1000的主要核设计准则。通过大规模并行计算表明，带燃耗计算功能的蒙特卡罗程序MCNP6能够在堆芯设计工作中发挥很好的参考作用。...

Bibliography:Background： AP1000, developed by the Westinghouse, is a pressurized water reactor with advanced passive safety systems. Two core fuel configuration schemes, D19 and Adv, are available for the AP1000. Purpose： This study aims to design a new core configuration scheme for AP1000, and compare it with D19 scheme by using Monte Carlo code Methods： First of all, a new core configuration scheme that combines the advantages of the D19 and Adv schemes was put forwarded. Then the D19 core scheme and the new core scheme were modeled by using the MCNP6 code. Finally, main nuclear design parameters of the new core scheme were calculated according to the varied fuel burnup. Results： The results indicate that the main physical parameters of the new scheme agree well with the AP1000 nuclear design criterion over the lifetime period of the first cycle. Conclusion： With the function of burnup calculation, Monte Carlo code MCNP6 play a good role in the reference process of core physical design by massively parallel computing.
