Note (General): It is thought to improve the prediction accuracy for burnup characteristics using many burnup data of "Joyo" effectively. It is thought the best way to adjust cross-sections using sensitivity coefficients of burnup characteristics to utilize burnup data of "Joyo". Therefore in this work computer codes for analyzing sensitivity coefficients of burnup characteristics had been prepared since 1992. The results are as follows: (1) The computer codes which could analyze sensitivity coefficients of burnup characteristics taking into consideration plural cycles and refueling were prepared, therefore it came to be able to adjust cross-sections using burnup data and to estimate the accuracy for design of large LMFBR cores. (2) The adequacy of prepared codes was made sure by comparing with direct calculations. (NB: This document is a translation of PNC TJ9124 94-007 Vol.2 published in March 1997.)
「常陽」等の実機燃焼データを設計で有効に活用するためには、燃焼核特性に対する核データ感度係数を解析し、これを用いて炉定数調整を実施する方法が最も有力である。そこで本研究では平成4年から燃焼核特性に対する核データの感度係数を解析するシステムの整備を実施してきた。2年間のシステム整備の成果は次の通りである。(1)燃焼核特性の感度係数を、複数サイクル及び燃料交換を考慮して解析可能なシステムを整備したことにより、実機燃焼データを用いた炉定数調整及び設計対象である大型炉の予測精度評価が可能となった。(2)直接計算との比較により、整備したシステムの妥当性を確認した。(注: 本報告書は1994年3月に発行された報告書(PNC TJ 9124 94-007 Vol.2)の翻訳である。)
