Description
Differences are discussed between RELAP-3and RELAP-UK computer codes developed for the LOCA analysis. RELAP-UK code is an advanced modification of RELAP-3 code. The former incorporates an improved mathematical model for the primary circulating loop processes including the space dependency of the flow rate, more adequate description of the two-phase flow through T-joints, a wider set of correlation dependencies for two-phase flow thermohydraulics at the cooling water sprinkling into a fuel rod bundle. A more efficient implicit technique for integration of the differential equations of the model has been applied. The details of the mentioned codes practical utilization on the computers available in ChSSR are discussed as well asthe encountered problems and the requirements to the computer base development
