HOTROD: a computer program for subchannel analysis of coolant flow in rod bundles

Technical Report ·
OSTI ID:4377696

A digital computer program is described for the steady-state thermal and hydraulic subchannel analysis of coolant flow in rod bundle reactor cores and heated-rod experimental test sections. The program allows for the transfer of two-phase fluid properties in three dimensions and predicts the local fluid conditions, fuel rod surface temperature and critical heat flux. The history of subchannel analysis in rod bundles is discussed. A detailed description is presented of the HOTROD analytical model, the numerical solution procedures and the program input formats.
