The Water Reactor Analysis Package-Evaluation Model (WRAP-EM) is a modular system of computer codes designed to provide the safety analyst with the capability of performing complete loss-of-coolant calculations for both pressurized- and boiling-water reactor systems. The system provides a licensing-type calculation capability and thus contains most of the Nuclear Regulatory Commission-Approved EM options, as described in the Code of Federal Regulations, Title 10, Part 50, Appendix K. All phases of an accident (blowdown, refill, and reflood) are modeled. The WRAP consists of modified versions of five preexisting codes (RELAP4/MOD5, GAPCON, FRAP, MOXY, and NORCOOL), the necessary interfaces to permit automatic transition from one code to the next during the transient calculations, plus a host of user-convenience features to aid the analyst faced with a multitude of EM calculations. The WRAP has been verified against both calculated and experimental results.
