The two-group point-kinetic component of neutron noise in a MSR
Paper in proceeding, 2014

The calculation of the point kinetic component of the neutron noise in two-group diffusion theory in Molten Salt Reactors (MSRs) using different techniques is discussed. First, the point kinetic component of the noise is calculated from the full space-frequency dependent solution analytically by a projection to the static adjoint. Then, the point-kinetic solution is derived by solving the simplified point kinetic equations. Both results are thereafter analyzed and compared quantitatively. This comparison shows that the solution of the simplified point kinetic equations significantly differs from the exact one and cannot reconstruct some important features of the true solution. The similar discrepancies between two methods were also observed and confirmed in earlier one-group MSR calculations.
