When a large negative reactivity is inserted into such a loosely coupled core system consisting of two-core and one-large-core reactors, spatial higher-harmonic modes are probably significantly excited. Consequently, the excitation leads to the failure of the one-point kinetics model, and the LSIKM based on the model infers spatially dependent reactivity and source strength. In this paper, we present a reduction technique for the apparent spatial dependence and a demonstration of the applicability of such a technique to rod drop experiments carried out in both the subcritical and critical states of the two-core reactor., この論文は日本原子力学会和文論文誌, Vol.9 No.3 (2010) 296に発表されたものを, 日本原子力学会の許可を得て転載するものである。 Ohsawa, Takaaki, application/pdf}, pages = {37--45}, title = {〈再録〉最小自乗逆動特性解析における空間依存性の低減}, volume = {47}, year = {2011}, yomi = {タニナカ, ヒロシ and ハシモト, ケンゴ and オオサワ, タカアキ} }
