Study on calculation methods for effective delayed neutron fraction

Irwanto, D.*; Chiba, Go; Nagaya, Yasunobu  ; Obara, Toru*

To calculate the effective delayed neutron fraction $$beta_{eff}$$ with a Monte Carlo code, Nauchi's method and van der Marck's method have been proposed. The errors due to these methods are quantified by using a deterministic code. It is found that van der Marck's method always results in larger values of $$beta_{eff}$$ than Nauchi's method and that a multi-generation effect, which is neglected in both the methods, has a significant impact on $$beta_{eff}$$ for reflected systems.
