United States Nuclear Regulatory Commission - Protecting People and the Environment

T5  Severe Accident Progression and Consequence Analysis in Support of Regulatory Decisionmaking in Light of the Fukushima Accident

The NRC’s MELCOR and MACCS codes model severe accident scenarios at nuclear power plants.  They work in conjunction to postulate severe accident releases to the environment and the potential consequences of the releases.  The session includes discussions of containment protection and release reduction (CPRR) for boiling-water reactors from NRC and industry perspectives and a post-Fukushima analysis.
