Abstract

Four series of ThO

samples in pellet form have been irradiated in high flux reactor under various conditions. After cooling and dissolution of each sample separately

the interrelations between

certain fission fragment nuclides and

have been determined. Based on these experimental results

the ranges of some physical parameters which might be useful to the design of Th-U nuclear reactor have been presented. Namely

1. Ratio of fast neutron flux to thermal neutron flux
