摘要

建立了基于WIMS和MCNP的临界-燃耗耦合计算方法，并对此方法进行了验算。通过栅元和组件问题的分析计算以及西安脉冲堆燃耗实验对比，验证了此耦合程序的可靠性和正确性。最后应用此耦合程序对医院中子照射器I型堆的燃耗进行了计算和分析。

Abstract

The paper set up the coupled calculation methods of criticality and burnup based on WIMS code and MCNP code, and validated the method. Through the calculation results of cells and the comparison of burnup experiments of Xi’an pulsed reactor, the validity and rationality of the coupled code were proved. The article utilized the coupled code to compute and analyze the burnup of in hospital neutron irradiator mark 1(IHNI-1) reactor at last.
