Study on advanced in-core fuel management strategy for PWR and CANDU nuclear power plants

A preliminary study on improving the in-core fuel management strategy of Qinshan PWR Nuclear Power Plant was summarized, which includes the extended cycle length, higher discharge burnup, application of advanced burnable poisons and low-leakage loading pattern, improvement of assembly design and raising the thermal power. The possible benefit and efficiency in economics were discussed. The feasibility study of using the spent PWR fuel in CANDU and forming an advanced fuel cycle of PWR/CANDU Synergism were proposed, which is of great economical and practical significance for the countries possessing both of the PWR and CANDU nuclear power plants.
