CONTEMPT-LT/028; CONTEMPT-LT/026; pressure-temperature response. [CDC7600,CYBER176; IBM360; FORTRAN IV and COMPASS (CDC7600), FORTRAN IV and BAL (IBM360)]
CONTEMPT-LT was developed to predict the long-term behavior of water-cooled nuclear reactor containment systems subjected to postulated loss-of-coolant accident (LOCA) conditions. CONTEMPT-LT calculates the time variation of compartment pressures, temperatures, mass and energy inventories, heat structure temperature distributions, and energy exchange with adjacent compartments. The program is capable of describing the effects of leakage on containment response. Models are provided for fan cooler and cooling spray engineered safety systems. One to four compartments can be modeled, and any compartment except the reactor system may have both a liquid pool region and an air-vapor atmosphere region above the pool. Each region is assumed to have a uniform temperature, but the temperatures of the two regions may be different. The user determines the compartments to be used, specifies input mass and energy additions, defines heat structure and leakage systems, and prescribes the time advancement and output control.CDC7600,CYBER176;IBM360; FORTRAN IV and COMPASS (CDC7600), FORTRAN IV and BAL (IBM360); SCOPE 2.1 (CDC7600), OS/MVT (IBM360); 58K (octal) bytes and a CalComp or microfilm plotter (CONTEMPT-LT/028); 430K bytes and a CalComp or SC4060 plotter for graphical output (CONTEMPT-LT/026).
