Application of Burnup Credit Technology in the Spent Fuel Reprocessing Plant
The construction of plant with a large processing capacity is the only way for the economic development of power reactors spent fuel reprocessing,spent fuel reprocessed by the plant has the characteristics of high initial enrichment of 235U and deep burnup,and the processing capacity of a single equipment is extraordinary large,which brings great challenges to the critical safety design and economy of the plant.Based on learn the design concept of international advanced reprocessing plant,combined with the characteristics of continuous dissolver and target spent fuel processed,this paper puts forward the application of actinide only burn up credit with 10 nuclides,and gives some key data such as burnup limit of fuel processed by dissolver and acceptance criteria of critical safety analysis through calculation.The results of this work show that the application of burnup credit technology in commercial spent fuel reprocessing plant can not only fundamentally solve the important nuclear safety problems of the plant,but also bring many benefits to the economic operation of the plant.
