摘要: An empirical core model construction procedure for pressurized water reactor (PWR) in-core fuel management problems is presented that (a) incorporates the effect of composition changes in all control zones a given assembly, (b) valid at times during cycle range variables, (c) allows determining optimal beginning (BOC) kappainfinity distribution as single linear programming problem,and (d) provides flexibility choice material to describe composition. Although modeling assumes zero BOC burnup, predicted profiles are also applicable reload cores. In construction, assembly power fractions and burnup increments regarded state (i.e., dependent) variables. Zone enrichments independent) The validated implemented initial PWR determine two three-zone scatter loading schemes. agree with results other investigators obtained by different techniques.
