NSPM Letter to NRC, "MNGP Final Response to NRC Request for Information Pursuant to 10 CFR 50.54(f) Regarding the Flooding Aspects of Recommendation 2.3 of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident," dated November 27,2012, ADAMS Accession No. ML12333A348.

In Reference 1, the Northern States Power Company, a Minnesota corporation (NSPM),
d/b/a Xcel Energy, provided the results of the external flooding walkdowns performed at the Monticello Nuclear Generating Plant (MNGP). These results were provided to the NRC as a result of information requested per 10 CFR 50.54(f) in a letter dated March 12,2012 (Reference 2). During subsequent reviews of the flooding walkdown report, NSPM identified two items in the Reference 1 report that require correction.
They do not impact the original conclusion of the Reference 1 report that the external flooding program is effective.
The purpose of this letter is to provide replacement pages to correct the original report.
The enclosure to this letter provides a description of the corrections needed. The attachment to the enclosure contains the replacement pages for the report.
Document Control Desk Page 2 If there are any questions on these corrections, or if additional information is needed, please contact Ms. Jennie Eckholt, Licensing Engineer, at 612-330-5788.
Summary of Commitments This letter proposes the following new commitment and no revisions to existing commitments.
Regulatory Commitments Due Date NSPM will submit an updated external flooding walkdown November 20, 2013 report with a summary of the results of the restricted access walkdowns.
I declare under penalty of perjury that the foregoing is true and correct.
Executed on March 29, 2013.

ENCLOSURE Description of Corrections and Attachment with Replacement Pages for MNGP's External Flooding Walkdown Report On March 12,2012, the NRC Staff issued Reference 2 to all NRC power reactor licensees and holders of construction permits in active or deferred status. Enclosure 4 of the March 12, 2012 letter contains specific Requested Actions, Requested Information, and Required Responses associated with Near-Term Task Force (NTTF)
Recommendation 2.3, Flooding. In Enclosure 4 of Reference 2, the NRC requested licensees to perform flooding walkdowns to verify that plant features credited in the current licensing basis (CLB) for protection and mitigation from external flood events are available, functional, and properly maintained. Northern States Power Company, a Minnesota corporation (NSPM), d/b/a Xcel Energy, provided the results of Monticello Nuclear Generating Plant's (MNGP) external flooding walkdowns in a letter with an enclosed report dated November 27,2012 (Reference 1).
During subsequent reviews of the Reference 1 flooding walkdown report, NSPM identified two items requiring correction.
- Procedure Step Incorrectly Referenced
- Building Incorrectly Classified as Locked High Radiation These corrections are described in more detail in the following sections. Two replacement pages are provided in the Attachment to this enclosure to correct the flooding walkdown report.
1.0 Procedure Step Incorrectly Referenced Item 3 in Table 3.6-1, "Deficiency List," of Reference 1 incorrectly references the procedure step 5.2.11.H of the MNGP procedure A.6, "Acts of Nature." The table should reference step 5.2.11.W. One replacement page (page 23) is provided in the attachment to this enclosure to correct the flooding walkdown report.
2.0 Building Incorrectly Classified as Locked High Radiation Areas or buildings which were not readily accessible during the flooding walkdowns were provided in Table 3.6-3, "Restricted Access," of Reference 1. Item number 25 of this table identified the Compressed Gas Storage Building as a locked high radiation area. However, it was identified during the work order planning process that the areas requiring inspection are not locked high radiation areas and are accessible during normal plant operations. NSPM has entered this issue into the Corrective Action Program, and will complete the walkdown of the Compressed Gas Storage Building by October 31, 2013 per the commitment in Reference 1. One replacement page (page 28) is provided in the attachment to this enclosure to correct the flooding walkdown report.

ENCLOSURE Description of Corrections and Replacement Pages for Monticello Nuclea'r Generating Plant's External Flooding Walkdown Report 3.0 Updated External Flooding Walkdown Report NSPM originally committed to complete the inspection of flood protection features identified in Table 3.6-3, "Restricted Access," of Reference 1 by October 31,2013. Any deficiencies identified as a result of the completion of these inspections will be provided to the NRC in an updated external flooding walkdown report. NSPM will submit an updated external flooding walkdown report with a summary of the results of the restricted access walkdowns by November 20, 2013.
