Hybrid method for ex-core detector response
Year: 1997
Type: conference-paper
Abstract: Calculations have been completed to predict currents for ion chambers located in a shield tank exterior to a reactor vessel. The detector response is best described using a Monte Carlo transport theory calculation showing the detailed detector region geometry. To save computer time, a hybrid method has been used, whereby neutron attenuation between the core and the shield tank is calculated by deterministic methods and the results are spliced to the Monte Carlo detector calculation. The approach used has the effect of separating the detailed description of the neutron source distribution in the core from the detailed Monte Carlo description of the neutron detector environment. Comparisons have been made to measurements and to calculations using a purely Monte Carlo approach.
