Description
An absolute measurement of 238U capture rate was made on FCA Assembly V-2, a physics mock-up of JOYO. The method is that 239Np activities were counted with a Ge(Li) detector which had been absolutely calibrated by using 238U foils irradiated in the standard thermal neutron facility. The absolute fission rate was also measured with an absolute fission counter of enriched uranium and we obtained 0.141 +-3% for 28σsub(c)/25σsub(f) at the core center. This value is larger than the calculated ones with the JAERI-FAST Version II, RCBN and ABBN set. (author)
