OECD Releases Report: Occupational Radiation Protection in Severe Accident Management
Posted on January 29th, 2015

The ISOE Expert Group on Occupational Radiation Protection in Severe Accident Management and Post-Accident Recovery (EG-SAM) of the OECD recently released the report “Occupational Radiation Protection in Severe Accident Management”. This working group of international experts drafted the report to apply lessons learned from the TMI, Chernobyl and Fukushima accidents along with industry best practices to severe accident management in conditions that are beyond design basis and involve significant core degradation.

The report provides in-depth information and guidance on the following topics:

  • Radiation protection management
  • Training for severe accident management
  • Plant design impacts on severe accident response strategies
  • Worker protection in severe accident environments
  • Monitoring and contamination control during initial response efforts

The document specifically addresses RP management approaches for mitigating a severe accident and the access controls needed for a highly damaged site, including guidelines on access to high radiation and highly contaminated areas, selection of proper RP protective tools, recommended instrumentation for use in severe accident conditions, means to fix and eliminate contamination, and emergency/accident individual dosimetry and assessment.

The ISOE provides a forum for radiation protection professionals from nuclear electricity utilities and national regulatory authorities worldwide to share dose reduction information and operational experience to optimize worker radiological protection at nuclear power plants. In addition, ISOE with its participating utilities and groups is a core group in developing safe, sustainable and societally acceptable strategies for emerging issues in the field of occupational radiation protection.

The ISOE EG-SAM was established by the ISOE board in 2011 in response to the accident at the Fukushima Daiichi Nuclear Facility to provide future guidance on methods to minimize the impact of severe accidents to workers and the public. Jay Tarzia of RSCS has been a member of ISOE EG-SAM workgroup since 2012.
