A method of computing hydraulic jet reaction force at a 100% steamline break is presented. The steamline break analysis is performed by the use of the NOTRUMP code. Formation of supersonic flow at the converging-diverging flow restrictor is computed with a homogeneous equilibrium model. Consideration is given, however, to the slip ratio of the liquid and steam phases, thermal nonequilibrium effects, and normal and oblique shocks.
