Abstract:
1. A method of calculating rod peak criteria, comprising: calculating pin nodal exposures and pin nodal powers of a plurality of rods in a plurality of fuel assemblies using a pre-defined process; calculating, for each of the plurality of rods, a rod average exposure using a weight factor associated with the rod, each weight factor based on one of a nodal weight and a pin weight of the rod; calculating a plurality of rod average powers of the plurality of rods in all of the fuel assemblies of the plurality of fuel assemblies; inputting a rod average exposure limit and a power limit for an alternative source term; developing core maps from the plurality of calculated rod average exposures and powers using the inputted rod average exposure limit and the inputted power limit; outputting the developed maps; and editing the developed maps.
