Higher order polynomial expansion nodal method for hexagonal core neutronics analysis

Annals of Nuclear Energy, 1998
Abstract A higher-order polynomial expansion nodal(PEN) method is newly formulated as a means to improve the accuracy of the conventional PEN method solutions to multi-group diffusion equations in hexagonal core geometry. The new method is applied to solving various hexagonal core neutronics benchmark problems.

The Green’s Function Nodal Expansion Method for Light Water Reactor Diffusion Calculations

Nuclear Science and Engineering, 1995
Green`s function nodal expansion method (GNEM) is developed for the efficient numerical solution of the multidimensional neutron diffusion equation. It is an improved version of the nodal expansion method (NEM) and the nodal Green`s function method (NGFM). The node interior fluxes are approximated by a high-order polynomial expansion as in NEM.

An application of the nodal expansion method to the determination of the radial temperature distribution in a nuclear fuel rod

Annals of Nuclear Energy, 2018
Abstract Within nuclear reactor simulation codes, the temperature distribution inside the fuel rod is computed with a mono-dimensional cylindrical heat conduction model. The main discretization methods applied to reduce the differential equation into an algebraic system are the finite difference or the finite volume method.
