United States Nuclear Regulatory Commission - Protecting People and the Environment

Updates to the MAACS Consequence Analysis Code

Sponsored by the Office of Nuclear Reactor Regulation

The U.S. Nuclear Regulatory Commission (NRC) developed MELCOR Accident Consequence Code System Version 2 (MACCS2) to evaluate the offsite consequences from a hypothetical release of radioactive material into the atmosphere. The code models atmospheric transport and deposition, emergency response actions, exposure pathways, health effects, and economic costs.

This poster presentation will show how MACCS2 is used to evaluate the consequences of severe radiological accidents as part of the environmental reports and environmental impact statements for early site permits, to support the plant-specific evaluation of severe accident mitigation alternatives required as part of the environmental assessment for license renewal, to assist in emergency planning, and to provide input to cost/benefit analyses.
