The proposed relief requests the use of alternatives to certain American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI requirements.

The U.S. Nuclear Regulatory Commission (NRC) staff has determined that the additional information below is needed to complete its review of the application.

The fluence value used in the June 26, 2015, request is based on the December 18, 2013, license amendment request.

NRC staff noted that the fluence at the clad-to-base metal interface in Table 3 of the June 26, 2015, submittal does not match that from Table B-5 of the December 18, 2013, license amendment request.

Clarify the above inconsistency and revise the June 26, 2015, letter (as needed) to accurately reflect the fluence on the beltline, circumferential (girth) weld.
