Subject:

Revision to Post-Restart CAL Commitment for Containment Internal Structure Beam 22A and Beam 22B

Reference:

Letter from OPPD (L. P. Cortopassi) to NRC (M. L. Dapas), "Integrated Report to Support Restart of Fort Calhoun Station and Post-Restart Commitments for Sustained Improvement," dated December 2, 2013 (LIC-13-0164)

(ML13336A785)

Dear Mr. Dapas:

In the Reference letter containing the post-restart commitments for Fort Calhoun Station, Omaha Public Power District (OPPD) in Enclosure 2, Section 4.b. stated:

"Regarding Beam 22A and Beam 22B in the containment internal structures, prior to resuming power operation following the first refueling outage after restart, OPPD will restore full structural design margin as described in the Fort Calhoun Station licensing basis."

Due to complexity of design and the ability to obtain the necessary pre-engineered components in sufficient time to complete the activities for this commitment in the time allotted, OPPD is deferring completion of this commitment from Fort Calhoun Unit 1 Refueling Outage 27 (FC1 R

27) to Refueling Outage 28 (FC1 R 28), which is currently scheduled for the fall of 2016. The revised commitment is:

Mr. Marc L. Dapas LI C-15-0042 Page2 Commitment: OPPD will implement the following commitment regarding structures inside the containment building:

1. Regarding Beam 22A and Beam 22B in the containment internal structures, prior to resuming power operation following Fort Calhoun Station Unit 1 Refueling Outage 28, OPPD will restore full structural design margin as described in the Fort Calhoun Station licensing basis.

If you should have any questions, please contact Terrence W. Simpkin, Manager, Site Regulatory Assurance, at (402) 533-6263.
