Calculation of the neutron noise using the Analytical Nodal Method

• In this study, the neutron noise, i.e. the stationary fluctuations of the neutron flux around its mean value, iscalculated in 2-group diffusion theory for a 2-dimensional reactor using the Analytical Nodal Method. Abrief description of the calculation of the static flux is also included. The same calculational scheme for theneutron noise as for the static flux is used. As a benchmark, the calculated neutron noise for a 2-dimensionalfully homogeneous reactor is compared with the analytical solution which can easily be determined for homogeneousreactors. The result of the benchmark is that the numerically calculated neutron noise accuratelymatches the analytically calculated neutron noise.
