SUBJECT:

Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Beaver Valley Power Station P.O. Box 4 Shippingport, PA 15077 724-682-5234 Fax: 724-643-8069 10 CFR 50.54(f) Addendum to the Beaver Valley Power Station, Unit No. 1, Near-Term Task Force Recommendation 2.3 Seismic Walkdown Report On March 12, 2012, the Nuclear Regulatory Commission (NRG) issued a letter titled, "Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3 of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident," to all power reactor licensees and holders of construction permits in active or deferred status. Enclosure 3 of the 10 CFR 50.54(f) letter contains specific Requested Actions, Requested Information, and Required Responses associated with Recommendation 2.3 for Seismic Walkdowns. By letter dated November 27, 2012, FirstEnergy Nuclear Operating Company (FENOC) submitted the 180-day response to the 10 CFR 50.54(f) letter. The required seismic walkdown reports were provided for Beaver Valley Power Station, Unit No. 1; Beaver Valley Power Station, Unit No. 2; Davis-Besse Nuclear Power Station; and Perry Nuclear Power Plant. During the seismic walkdowns, certain plant areas were inaccessible due to conditions expected during normal power operation. FENOC committed to submit a supplemental report documenting the results of the additional seismic walkdowns performed during a specified refueling outage. As committed for Beaver Valley Power Station, Unit No. 1, the additional seismic walkdowns were completed during the fall 2013 refueling outage. FENOC hereby submits the enclosed addendum to the Beaver Valley Power Station, Unit No. 1, Near-Term Task Force Recommendation 2.3 Seismic Walkdown Report.

Beaver Valley Power Station, Unit No. 1 L-13-376 Page 2 There are no regulatory commitments contained in this letter.

Addendum to Beaver Valley Power $tation Unit 1 Near-Terun Task Force Hec$mffiendation 2'3 Seismic Walkdown Repsrto Rev 1 Dated $eptember 4,201 3 November 1, 2013 Prepared by: Reviewed by: Approved by: FirstEnergy Nuclear Operating Gompany (FHNOC)

Purpose:

In response to the NRC Letter 50.54(0 Section 2.3, FirstEnergy Nuclear Operating Company (FENOC) submitted its response to the Nuclear Regulatory Commission (NRC) in Novemb er 2012 for its Beaver Valley Power Station (BVPS) Unit 1. Additionally, the Revision 0 repofi was revised in September2Ol3 based on the feedback received from NRC audit at BVPS conducted in July 2013. Pages 248 & 291 of the submittal report Table 6-3 identified 13 components that were not accessible during the time initial walkdowns were performed while the plant was in operation. A commitment was added in the report stating that these 13 items will be walked down during the next refueling outage. The purpose of this addendum to the report is to document the findings of those 13 components that were walked down during the September/October 2013 (IR22) refueling outage. Attachments: Revised page 284, Section 6.1 to identify the 13 inaccessible components that were walked down during the September/October 2013 refueling outage and also to indicate three additional components that were walked down. Also adds reference to additional Table 6-5 mentioned in item 3 below. Revised page 291 and292Table 6-3 and TabIe6-4 to include the additional 3 components walked down during the September/October 2013 refueling outage. Added page 292A to include an additional Table 6-5 to identify areas walked by inside the Containment Building during the September/October 2013 refueling outage. Seismic Walkdown Checklists for l3 components that were identified as inaccessible in the original submittal report and also for 3 additional components walked down. Area Walk-By Checklists associated with the components stated in item 4 above. Findings: No potentially adverse findings were identified for these components and in the associated rooms. The findings are documented in the attached Seismic Walkdown Checklists (SWC) and the associated Area Walk-By Checklists (AWC). 1. 2. 3. 4. 5.

6-5 and Table 6-6. The tables document "potential" issues that would be adverse to quality. In general, they are a documentation of varying degrees of experience and use of engineering judgments. The basis for excluding an issue from being a condition report is documented in the walkdown checklist to ensure retrievability. 6.0

SUMMARY

OF THE WALKDOWN RESULTS Wam DowN Irnus AND Wllr-Bv Anpa,s 6.1 The SWEL 1 included a total of I 13 components, and SWEL 2 included a total of 8 components. From this totalof 12I components, 108 components were walked down and 13 components were inaccessible and will require walkdown during the next plant's refueling outage. Notification No. 600788346 was generated to have these walkdowns performed during the next refueling outage. (These 13 components were walked down during the September/October 2013 refueling outage as indicated in the footnote to Table 6-3 on page 291.) Three additional components (PCV-IIA-117, PT-IRC-402, and MOV-1CH-310) were walked down during the September/October 2013 Refueling Outage as they were located in the same vicinity of the area of scheduled walk downs. Table 6-1 and Table 6-2 rdentify the walkdown items and walk-by areas, respectively, and Table 6-3 presents a list of items on the SWEL which are inaccessible while the plant is in operation. Three motor operated valves MOV-1QS-1018, MOV-15I-8608, and MOVE-15I-862A were part of the SEL components to be walked down. As noted on their respective checklists, the valves themselves were inaccessible, but the operators were accessible. The operators were walked down, but the in line valves were not. The areas walk-by and the walkdown items are cross correlated on the respective SWCs and AWCs. TabLe 6-4 provides the list of equipment that was walked down, by EPRI equipment class. Table 6-5 identifies the walk-by areas in the Containment Building which are inaccessible while the plant is in operation.

Anchorage

l. Is the anchorage configuration verification required (i.e., is the item one of the 50o/o of SWEL items requiring such verification)?

The distance from the top of the actuator to the pipe center line is -3 ft This MOV has a Limitorque actuator and is laterally supported to an adjacent wall by a steel brace member.

2. Is the anchorage free of bent, broken, missing or loose hardware?

3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Valvefound in good condition.

4. Is the anchorase free of visible cracks in the concrete near the anchors?

5. Is the anchorage configuration consistent with plant documentation?

(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)
