MONTE CARLO SIMULATION OF A BURNUP-AVERAGED 78-ELEMENT CANADIAN SCWR AND SIMILARITY STUDY WITH THE ZED-2 TEST REACTOR

摘要

Properties of the 78-element Canadian SCWR with (Th, Pu)O2 fuel are calculated for a burnupaveragedcore. The similarity between the SCWR and existing ZED-2 test reactor experiments isanalyzed and possible ZED-2 experiments are proposed. The modeling codes DRAGON andDONJON are used to develop an equilibrium core and the SCALE 6.0 package is used toperform similarity studies. The CVR for the SCWR is found to be close to zero, an improvementto the CANDU6. The similarity between the SCWR and existing ZED-2 experiments is low. Toachieve a high similarity a test fuel with 13% PuO2 is proposed.
