Description
The design basis loss of coolant accident (LOCA) for light water nuclear reactors postulates a major break in a coolant line. Both the response of the reactor vessel and its mechanical system as well as the response of the pressure suppression containment system exterior to the pressure vessel are of primary interest following such an event. The ability to determine system response and the suitability of particular mechanical and structural design features in both cases is predicted on the completeness with which the dynamic environment created in the various compartments is treated. In January of 1976, the Lawrence Livermore Laboratory (LLL) began a program for the NRC (RSR) to provide a sample problem solution activity which treats by numerical analysis the air-steam-water system flow implied by a LOCA. As a basis and focal point for modeling, the program addressed itself to the pressure suppression pool dynamics representative of the Mark I BWR. Program activities to date are described.
