Reactivity estimation of KUCA subcritical cores, 2; Estimation based on power profile in quasi-steady state

Yamane, Yuichi  ; Araki, Shohei   ; Kitamura, Yasunori*; Misawa, Tsuyoshi*

A new reactivity estimation method has been developed based on the power profile in quasi-steady state. Several subcritical cores were set up in KUCA A-core and neutron count rate was measured to apply estimation methods for comparison. The values obtained by new method, E, in an near-critical core and calculated value by using MVP code, C, show C/E in the range between 0.9 and 1.5.
