The reactor core design

mechanical design of cobalt adjuster rod assembly and safety analysis have been performed after the 21 stainless steel adjuster rod assemblies were replaced by cobalt adjuster rod assemblies in the reactivity control system of CANDU-6 reactor.The analysis results show that the grouping

distribution in reactor

and operation mode of the cobalt adjuster rod assemblies are the same as the stainless steel adjuster rod assemblies.During the operation of the cobalt adjuster rod assemblies for producing 60Co

the reactor core nuclear property

the reactor safety operation

and the radioprotection safety can be preserved.
