UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 2, 2014 The Licensees of Operating Power Reactors on the Enclosed List
SUBJECT:
ACKNOWLEDGEMENT OF LICENSEE DOSE ASSESSMENT SUBMITTALS ASSOCIATED WITH NEAR-TERM TASK FORCE RECOMMENDATION 9.3 RELATED TO THE FUKUSHIMA DAI-ICHI NUCLEAR POWER PLANT ACCIDENT: USE OF MANUAL CALCULATIONS In the U.S. Nuclear Regulatory Commission's (NRC's) Near-Term Task Force (NTTF) Report, "Recommendations for Enhancing Reactor Safety in the 21st Century," issued July 12, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML111861807), the NTTF recommended that an order be issued requiring licensees to develop and add guidance to their emergency plan regarding how to perform multi-unit dose assessments. The Fukushima Dai-ichi accident highlighted the importance of the availability of a multi-unit dose assessment capability in responding to a similar event. By letter dated February 27, 2013 (ADAMS Accession No. ML13029A632), NRC staff requested that the Nuclear Energy Institute (NEI) provide additional information on the number of sites that currently have multi-unit dose assessment capabilities, and the date by which all sites will have these capabilities. By letter dated March 14, 2013 (ADAMS Accession No. ML13073A522), NEI informed the staff that each licensee would provide, to the NRC, their multi-unit and/or multi-source dose assessment capabilities no later than June 30, 2013.
By letters dated in June 2013, you provided a submittal to the NRC regarding multi-unit and/or multi-source dose assessment capabilities. On September 5, 2013, the NRC staff conducted a teleconference with you regarding a generic technical issue (ADAMS Accession No. ML13266A407) contained in your initial submittal. The NRC staff identified that manual calculations appeared to be the interim and permanent multi-unit/multi-source dose assessment capability, rather than a fully automated permanent capability. The NRC staff communicated the expectation that licensees should have a fully automated multi-unit/multi-source dose assessment process rather than relying on manual calculation. By letters dated in October 2013, you supplemented your submittal to implement new/modified software that will ensure automated multi-unit/multi-source dose assessment capability by December 31, 2014 without a reliance on the use of manual calculations.
The NRC staff reviewed the supplemented information, and noted that the combined initial and supplemental responses provided: a summary of your current capabilities to perform multi-unit and/or multi-source dose assessments; and the anticipated schedule with due dates to establish it on an interim and/or permanent basis (if these are not current capabilities), with a final implementation date for permanent multi-unit and/or multi-source dose assessment capabilities that did not exceed December 31, 2014. In reviewing these capabilities, the NRC staff considered whether your automated computer program would demonstrate the ability to model offsite dose assessment conducive to developing Protective Action Recommendations.
The NRC staff expects that, as part of the implementation of these new dose assessment capabilities, an appropriate level of site procedures and training will be provided to ensure adequate integration and licensee staff familiarity. NRC staff will verify the implementation of these dose assessment capabilities through the inspection program.
Should you have any questions regarding this letter, please contact Brian Harris at (301) 415-2277.
