COSINE软件包堆芯物理分析程序在AP1000堆芯核设计中的初步应用及分析

Preliminary Application and Analysis of Physics Analysis Code in COSINE Package in Nuclear Design of AP1000

堆芯物理分析计算程序CORE是COSINE项目的一部分,主要用于反应堆堆芯的核设计计算。本文以AP1000反应堆为例,应用CORE程序对该型反应堆进行了初步的核设计计算,计算内容包括燃耗计算、功率分布计算、硼降曲线、价值计算等。计算结果表明,CORE程序基本达到了工程精度的要求。

The CORE code used in nuclear analysis of the reactor is part of COSINE project. In this paper, the CORE is preliminarily used in the AP1000 reactor nuclear design calculation to verify the capability of the CORE. The calculation contents include burnup calculation, power distribution calculation, boron concentration calculation and the xenon worth calculation. The results show that the CORE can meet requirements of the nuclear design calcualtion.
