Development and validation of gamma-heating calculational methods for plutonium-burning fast reactors

2005
The need for accurate calculational tools for the determination of gamma heating in fast reactors has increased considerably in recent years following the planned modification of certain existing fast breeders into plutonium-burning configurations. The latter are characterized by a steel/sodium reflector (replacing the fertile blanket) and a large number of core diluting sodium/steel sub-assemblies, i.e. regions in which gammas account for about 90 % of total heating. In the current doctoral
