Metcalfe, L J

CONTEMPT4/MOD2 describes the long-term behavior of multicompartment pressurized water reactor (PWR) containment systems and experimental containment systems subjected to postulated loss-of-coolant accident (LOCA) conditions. The program calculates the time variation of compartment pressures, temperatures, mass and energy inventories, heat structure temperature distributions, and intercompartment mass and energy exchange based on user-supplied values for compartment descriptions, time-step and edit controls, and selected problem features. Analytical models available to describe containment systems include models for containment fans and pumps, cooling sprays, fan coolers, heat conducting structures, sump drain, and PWR ice condensers. Optional automatic time-step control allows the code to determine time-step sizes within limits dictated by the user.CDC7600; FORTRAN IV (96%) and COMPASS (4%); SCOPE 2.1; 160,000 (octal) small core memory (SCM) and 100,000 (octal) large core memory (LCM) are required for CONTEMPT4 compilation. CalComp or FR80 plotting devices are needed for graphical output.
