Task 3.2. Irradiation transport modeling (Energorisk lead)
Both VVER 440 and 1000 model including fuel, internals and RPP completed. To be extended to the CBS using empirical flux decay. Need to provide Energorisk data on the water content, and the pre-heating protocol of the concrete shield (possibly comparable to the protocole described in Elleuch, L.F. and Dubois, F. and Rappeneau, J. (1972). Effects of Neutron Radiation on Special Concretes and Their Components, Special Publication of The American Concrete Institute, 43:1071-108. The scope of this task is limited to providing neutron, gamma and heat source fields. The coupled moisture transport-heat transfer in the CBS is to be addressed in task 3.1. Operation data to be exchanged from Fortum/CTU to Energorisk
