Description
We have performed two experiments in the fast critical assembly BFS to measure the effective delayed neutron fraction βeff values and compared the results to validate the βeff computation code, BETAK. Measurements of βeff were carried out in a metallic plutonium core and a metallic uranium core with Cf252 source pseudo-reactivity method. Fission integrals and correction factors, which were used to obtain the experimental βeff values, were calculated by using the LMR core design computation code system of KAERI. BETA-K has been developed consistently with the hexagonal Nodal Expansion Method (NEM) and it used delayed neutron dat of ENDF/B-VI. By comparing the computed βeff values with the measured ones, we found that the results from BETA-K agreed with the experimental values within the experimental error bound.
