Application of Homotopy Analysis Method and Adomian Decomposition Method for the Solution of Neutron Diffusion Equation in the Hemisphere and Cylindrical Reactors
Abstract: In the present paper, Homotopy Analysis Method and Adomian Decomposition Method are applied to obtain the analytical approximate solutions of neutron diffusion equation for both finite cylinders and bare hemisphere. Numerical results are provided by considering zero flux boundary (ZF) as well as extrapolated boundary conditions (EBCs). The explicit solution for critical radius and flux distributions are represented graphically. Keywords: Homotopy analysis method, Adomian decomposition method, ZF boundary conditions, neutron …

Recurrent Neural Network Model for Signal Prediction in a LOCA Event
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 In this study, an artificial neural network (ANN) model with the Elman recurrent structure is developed to predict thermo-hydraulic signals in a loss of coolant accident (LOCA). In the prediction procedure, a few previous samples of a signal at the time of the accident are fed to the ANN and the output value of next time steps are estimated by the network output. The …

Regulatory Approach for Safe Long-term Storage –Human Intrusion Scenario
Abstract: Storage is a necessary step in the management of radioactive waste. In recent years, storage step is extended; serious consideration has been given, in some countries to the use of storage as a long-term management option. This option, in particular is considered for spent fuels, high-level, and long-lived wastes. Reactor production of Mo-99 generated high and lived radioactive wastes. These wastes require complex and expensive facilities for extensive handling, separation, …
