SUBJECT:

INTERIM 10 CFR PART 21 REPORT REGARDING SUBMODULE AND EMBEDMENT DEVIATIONS FOR V.C. SUMMER UNIT 2 AP1000 PROJECT The attachment to this letter provides an interim report in accordance with 10 CFR 21.21 pertaining to submodule and embedment deviations for the V.C. Summer Unit 2 AP1000 nuclear project. Based on information described in site quality control inspection reports, deviations were identified in the Unit 2 CA-01 and CA-05 structural submodules, and also in some safety-related embedments.

Evaluation of reportability in accordance with 10 CFR Part 21 was not able to be completed within the 60-day evaluation period due to the recent discovery that the initial evaluation of these conditions incorrectly determined that no additional evaluation was required. These conditions were discovered during reviews conducted due to discovery of other similar conditions. It is currently expected that the evaluation of these conditions will be completed by October 21, 2014.

If you have any questions pertaining to this information, please contact Curtis Castell, Licensing Manager, at 980-321-8314.

Sincerely, Don DePierro Senior Vice President, Nuclear cc:. Regional Administrator, USNRC, Region II Attachment
