RELAP5 application to integral experiments. [PWR]
RELAP5 is a one-dimensional light water reactor (LWR) transient analysis code. The outstanding features of the code are its versatility, fast running, and ease of use. The released version of the code, RELAP5/MOD1, is available from the National Energy Software Center and is being maintained. Error corrections and minor improvements are added to the code periodically as updates (cycle 18 contains the latest updates to the code). The RELAP5/MOD1 code contains the necessary models for simulation of LWR depressurization and operational transients. This version of the code is particularly well suited to simulation of small break loss-of-coolant accidents (LOCAs) and has been used extensively at the Idaho National Engineering Laboratory (INEL) in support of the Semiscale and LOFT testing programs. The major limitation of RELAP5/MOD1 is the lack of reflood modeling capability, specifically the nonequilibrium heat transfer process in the subcooled boiling and post-CHF regimes. During 1982 new modeling capabilities were completed in addition to the maintenance activities related to RELAP5/MOD1. An interim version of the code, RELAP5/MOD1.5, containing most of the new features was released to the NRC for use by NRC contractors in August of 1982.
