SUMMARY
OF TELEPHONE CALL HELD ON NOVEMBER 9, 2009, BETWEEN THE U.S. NUCLEAR REGULATORY COMMISSION AND ENTERGY NUCLEAR OPERATIONS, INC., CONCERNING METEOROLOGICAL DATA USED FOR THE SEVERE ACCIDENT MITIGATION ALTERNATIVE ANALYSES Representatives of the U.S. Nuclear Regulatory Commission (NRC or the staff) and Entergy Nuclear Operations, Inc., (Entergy or the applicant) held a telephone call on November 9, 2009, to clarify how the meteorological data that were used in the severe accident mitigation alternatives (SAMA) were averaged. This call was a follow-up call to the call held on November 3, 2009.
During the call, Entergy informed the staff that based on a review of the meteorological data used for the SAMA analysis it discovered an error in how the wind direction data were averaged. Entergy stated that it has issued a condition report. It further stated that it will document the discovery of the error and that corrective action is being taken in a letter to the NRC.
Entergy plans to submit the results of a reanalysis of the MACCS2 calculations using corrected data. The staff asked Entergy to also include the following information in its submittal:
identification of the wind data used and its justification (e.g., if a single year is used or an average of several years),
revised estimates of the offsite population dose and offsite economic costs, identify which meteorological tower locations and heights were used for wind data and why they were selected, an assessment of the impact on the SAMA analysis results, specifically for the analysis case discussed in response to RAI 4e, dated February 5, 2008, and the complete MACCS2 input file used for the reanalysis (in electronic format).
The enclosure provides a listing of the participants.
The applicant had an opportunity to comment on this summary.
