Abstract
Actinides decay heat was measured for fast neutron fissions in the fast neutron source reactor “YAYOI” of the University of Tokyo. Measured nuclides were U-235 and Np-237, using beta and gamma spectroscopic method. The latest results on beta-ray and gamma-ray decay heat are reviewed in this paper. Measurement results were compared with those measured for U-235 in 1983 by Akiyama using the same method, as well as with the summation calculation results using JNDC-V2, ENDF-B/VI and JEF-2.2.
