Abstract
Description
−炉心要素及びRP構成要素の製造工程の不確定性;
−基本的機能(有効倍率、制御・保護システム棒の「重量」、電力密度場)の計算誤差;
−定誤差;
−組織的誤差;
−系統的誤差
であり、炉心の中性子の物理的特性及び熱液圧特性の開発及び証明の際に考慮すべきものである。
−保守性の増大により、シム棒バンク(SR、shim rod bank)の吸収材要素(AE、absorber element)がよりストレスの多い動作条件となることをなくし;
−シム棒の行程を増大させる必要性をなくして、製造中の制御工程を簡略化し;
−各特定の原子炉に対するAEを開発する必要性をなくし、全キャンペーンを通じて必要な未臨界の許容範囲、及び炉心のライフ・サイクル全体に必要な動作性を保証し;
−反応炉の安全制御アルゴリズムを簡略化する。
