Study on calculation methods for the effective delayed neutron fraction

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

It is rather difficult to measure the effective delayed neutron fraction with experiments, so it becomes important to obtain their accurate calculation values. We study calculation methods for the effective delayed neutron fraction by analyzing various fast neutron systems including the bare spherical systems (Godiva, Jezebel, Skidoo, Jezebel-240), the reflective spherical systems (Popsy, Topsy, Flattop-23), MASURCA-R2 and MASURCA-ZONA2, and FCA XIX-1, XIX-2 and XIX-3. These analyses are performed by using SLAROM-UF and CBG for the deterministic method and MVP-II for the Monte Carlo method. We calculate the effective delayed neutron fraction with various definitions such as the fundamental value, the standard definition, Nauchi's definition and Meulekamp's definition, and compare these results with each other.
