拡張炉定数調整法; 設計対象炉心核特性を考慮した炉定数調整法

Extended cross-section adjustment method; A Cross-section adjustment method considering the target core characteristics

横山 賢治

Yokoyama, Kenji

原子炉の核設計手法として、炉定数調整の段階であらかじめ設定した設計対象炉心核特性を考慮して断面積データを調整する新しい炉定数調整法を導出した。最新の高速炉積分実験データベースに適用した。この結果から、拡張炉定数調整法では従来炉定数調整法に比べてさらに設計精度が向上することが確認できた。

As a nuclear design method, a new cross-section adjustment method has been derived to take into account the target design core parameters which are selected before the cross section adjustment. The new method was applied to the latest integral experiment database for fast reactors. As a result, it is confirmed that the new method achieves further improvement for the design accuracy compared with the conventional cross-section adjustment method.
