MELCOR

MELCOR is a fully integrated, engineering-level computer code developed by Sandia National Laboratories for the U.S. Nuclear Regulatory Commission to model the progression of severe accidents in nuclear power plants. A broad spectrum of severe accident phenomena in both boiling and pressurized water reactors is treated in MELCOR in a unified framework. MELCOR applications include estimation of severe accident source terms, and their sensitivities and uncertainties in a variety of applications.

Register for 2021 VIRTUAL CSARP & MCAP Meetings

Mon, Jun 7, 2021, 4:00 AM –Fri, Jun 11, 2021, 8:00 AM MDT

The next Cooperative Severe Accident Research Program (CSARP) technical review and MELCOR Code Assessment Program (MCAP) meetings will be held virtually on June 7-11, 2021. There will be no MELCOR workshop.

The purpose of the CSARP/MCAP meetings is to exchange technical information on severe accident research including experiments and analytical models to address regulatory and safety issues. The meetings are open only to CSARP members.

• Platform: Microsoft Teams

• Start time: 6:00 AM US EDT (UTC-4; 12:00 PM Paris; 7:00 PM Tokyo)
