U.S. Nuclear Regulatory Commission Page 2 June 7, 2012 In developing a response to questions raised by the NRC in the Reference 2 request for additional information, TVA prepared a revised mission dose calculation for the dedicated individuals assigned to close the penetration hatch. The results of the revised calculation indicate that shielding will be required for protection of the dedicated individuals. After further review of the cost to obtain and install the shielding, and the reduced benefits considering the time remaining before the start of the SGRP refueling outage in October 2012, TVA has elected to withdraw the Reference 1 license amendment request.
There are no regulatory commitments associated with this submittal. If you have any questions, please contact Clyde Mackaman at (423) 751-2834.
