Development of Burnup Program Based on Chebyshev Rational Approximation Method
-
摘要: 基于切比雪夫有理近似法(CRAM)对燃耗方程进行求解,采用EAF数据库,开发了燃耗程序ABURN。计算了聚变堆第一壁活化例题和UO2燃料燃耗例题,并将ABURN程序的计算结果与欧洲活化程序FISPACT进行对比。结果表明,ABURN程序可达到FISPACT程序同等精度,并且由于采用了CRAM,程序在燃耗步设置方面具有高度的灵活性,初步验证了ABURN程序的可用性与准确性。

Abstract: A burnup code ABURN was developed based on Chebyshev rational approximation method(CRAM) and EAF database. This paper calculates the fusion reactor first wall and UO2 burnup problems. Compared with the European FISPACT, ABURN can achieve the same accuracy as FISPACT. Due to the CRAM method, this program has a high flexibility in terms of burnup steps, which verifies the feasibility and accuracy of ABURN program. -
