为验证多温度连续能量点截面库 CENACE-1.0用于堆芯释热计算的可靠性,利用 NJOY99/HEATR模块及自主研发的检测程序chkACEheat对CENACE-1.0常温库中各种材料进行能量平衡检查。检查结果表明,CENACE-1.0库中的KERMA系数和释热截面合格率较其他比对ACE库的好,但不合理KERMA系数目前仍普遍存在于各评价库中,需要发展直接修订KERMA系数计算结果的方法和手段。
為驗證多溫度連續能量點截麵庫 CENACE-1.0用于堆芯釋熱計算的可靠性,利用 NJOY99/HEATR模塊及自主研髮的檢測程序chkACEheat對CENACE-1.0常溫庫中各種材料進行能量平衡檢查。檢查結果錶明,CENACE-1.0庫中的KERMA繫數和釋熱截麵閤格率較其他比對ACE庫的好,但不閤理KERMA繫數目前仍普遍存在于各評價庫中,需要髮展直接脩訂KERMA繫數計算結果的方法和手段。

In order to verify the reliability of the multiple-temperature continuous energy cross section library CENACE-1.0 when used for calculating nuclear heating in reactor core ,NJOY99/HEATR module and auxiliary code chkACEheat developed locally were used to perform energy-balance check for all materials in the library .The test results show that the pass rate of KERM A factors and heat production cross sections of the CENACE-1.0 library is better than that of the other ACE libraries used as comparison . However ,unreasonable KERMA factors still exist in various evaluation libraries ,and methods to directly revise the calculation results of KERM A factors need to be developed .
