Summary:A computer program package has been developed, which supports the in-core fuel management activities for pressurized water reactors. The package generates and recommends an optimum-loading pattern to ensure safe and efficient reactor operation. The search for an optimum fuel-loading pattern has been conducted by predicting several core parameters such as the power distribution by means of an artificial neural network. This reduces the calculation time and makes it possible to analyse more loading patterns in the same time interval by increasing the probability of finding a desired optimum. A genetic algorithm method has been implemented and used to automate the loading pattern generation. The code has been tested using the data from the PWR Almaraz Nuclear Power Station in Spain.
