Available in PDF, EPUB and Kindle. Book excerpt: In this study, a computer program package has been developed which supports thein-core fuel management activities for pressurised water reactors, generates and recommends optimum loading patterns to ensure safe and efficient reactor operation.A search for an optimum fuel loading pattern must be conducted in the space ofseveral core parameters such as power distribution, which is an excessively timeconsuming computational process. Global core calculation codes take a relativelylong time to do the task. The time interval necessary for the iterative process was reduced by using an artificial neural network estimator for the calculations. In this way , it was possible to analyse more loading patterns in the same time interval and the probability of finding a desired optimum was increased.As a case study , the core of the Almaraz Nuclear Power Plant of Spain, a pressurised water reactor, was modelled for the core calculation code system. The 2-group cross sections for the fuel assembly types were calculated and stored for later usage with the diffusion code. The fuel depletion effects were omitted.2000 loading patterns were generated by placing fuel assemblies to random positions in the core, and for each pattern the power distribution and effective multiplication factor (keff) were calculated with the diffusion code. At the next stage, 500 of the loading patterns were introduced to the neural network as input data for the training process. The remaining 1500 patterns were used to validate the neural network implementation. It was shown that the neural network estimates the power distribution and the effective multiplication factor within acceptable error limits.To complete the system, a loading pattern generator was developed. This moduleconsists of a set of rules and an algorithm that places the fuel assemblies to core positions. The neural network estimated the power distribution and effective multiplication factor for the loading patterns that were generated. The patterns that have a maximum power fraction lower than, and a minimum effective multiplication factor higher than reference values were stored as candidate optimum patterns. At the last stage of the work, an alternative loading pattern generator based on genetic algorithm method was developed. in this method, an initial loading pattern is improved by applying the genetic operators to obtain the optimum. The loading patterns obtained from the simple rule-based and the genetic algorithm methods were compared, and the genetic algorithm was shown to be more successful.It was seen that, it is possible to automate in-core fuel management activities by applying artificial intelligence techniques.

This book was released on 1972 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel loading patterns which have a minimum power peak are economically desirable to allow power reactors to operate at the highest possible power density and to minimize the possibility of fuel failure. A computer code called SHUFLE was developed for pressurized water reactors which shuffles the fuel in search of the lowest possible power peaking factor. An iterative approach is used in this search routine. A radial power distribution is calculated from which the program logic Selects a movement of fuel elements in an attempt to lower the radial power peak. Another power calculation is made and the process repeated until a predetermined convergence is reached. The logic by which the code decides the fuel movement is presented, along with the criteria for accepting or rejecting the move after a power calculation of the new loading pattern is made. A 1.5 group course mesh diffusion theory method was used to obtain the power distribution for each SHUFLE iteration. Convergence to a final loading pattern varies from about 10 to 40 shuffling iterations depending on the initial loading presented to the code. Since the typical computer running time for a one-quarter core power distribution with this 1.5 group method is only one to a few seconds, depending on the loading, convergence to a good loading pattern takes on the order of one minute on a Univac 1108. The low computer cost plus ease of operation should make this code of considerable use in determining loading patterns with minimum power peaking for any given set of fuel elements. The program also has burnup capability which can be used to check power peaking throughout core life. A parametric analysis study of fuel cycle costs for a PWR is also presented. Cost parameters analyzed were variation in the cost of yellow cake, enrichment, money, fabrication, and reprocessing plus changes in burnup, load factors, power densities, and the effect of forced early discharge. Figures are presented to indicate total fuel costs as a function of burnup for these cost parameters. Linear relationships for minimum cost and optimum burnup are presented for each parameter.
