State-Of-The-Art Reactor Consequence Analyses (SOARCA)

The SOARCA project is a combined effort of the Offices of Nuclear Regulatory Research
(RES), Nuclear Reactor Regulation (NRR), and Nuclear Security and Incident Response (NSIR)
to: (1) evaluate and update, as appropriate, analytical methods and models for realistic
evaluation of severe accident progression and offsite consequences; (2) develop
state-of-the-art reactor consequence assessments of severe accidents and replace such
analyses as NUREG CR-2239, "Technical Guidance for Siting Criteria Development," dated
December 1982; and (3) identify mitigative measures that have the potential to significantly reduce risk of offsite consequences.

To conduct the analyses, staff will use an improved understanding of source terms and severe accident phenomenology, and credit the use of severe accident mitigation strategies and procedures, that were not in place when the 1982 study was performed. In addition, staff will use updated emergency preparedness modeling assumptions, and account for plant improvements.
