These research activities have been concentrated on the Feynman- α neutron correlation analysis on time domain and the power spectral analysis on frequency domain. At present, the latter power spectral analysis is of greater advantage than the former Feynman-α one, forperiodic and pulsed neutron source. While Feynman- α formula for pulsed neutron source is too complicated to be fitted directly to variance-to-mean ratio data, the power spectral analysis has a simpler formula based on the first-order reactor transfer function. The Feynman- α should be improved to consider spatial effect of deeply subcritical system and instability of accelerator operation. Further subject of reactor noise analyses is an improvement for high power operation., application/pdf}, pages = {19--30}, title = {<解説>加速器駆動未臨界炉に対する炉雑音解析研究の現状と課題}, volume = {50}, year = {2014}, yomi = {ハシモト, ケンゴ} }
