Subject:
Oconee Nuclear Station Docket Number 50-287 Supplement to License Amendment Request associated with New Reactor Building Emergency Sump (RBES)
Strainers, TSC Number 2004-08 This is a supplement to the License Amendment Request (LAR) submitted by Oconee Nuclear Station (ONS) on August 18, 2005.
In that submittal, ONS proposed to amend Appendix A, Technical Specifications (TS), for Renewed Facility Operating Licenses DPR-38, DPR-47 and DPR-55 for ONS Units 1, 2, and 3. The proposed change to Technical Specification (TS) Surveillance Requirement (SR) 3.5.2.6 and SR 3.5.3.6 removed reference to 1"trash racks and screens" and replaced this terminology with the word "strainers".
The intent of the request was to make the TS surveillance wording consistent with the as-built configuration which will exist after one or more replacement strainers are installed in response to Generic Letter 2004-02.
On November 1, 2005, NRC approved the request for Units 1 and 2, and issued amendments 348 and 350 to Renewed Facility Operating Licenses DPR-38 and DPR-47 respectively. NRC withheld approval for Unit 3 pending ONS' completion of (and NRC acceptance of) evaluation of the impact of pipe whip, jet impingement, and missile generation for Unit 3. The amended TS pages provided by the NRC along with the.approved amendments for Units 1 and 2 did not accurately reflect the status of Unit 3. Therefore, after conferring with the NRC, ONS made an administrative change to create two versions of the affected pages for implementation.
Thus the affected pages, 3.5.2-5 and 3.5.3-3, became 3.5.2-5a, 3.5.2-5b, 3.5.3-3a, and 3.5.3-3b. Pages 3.5.2-5a and 3.5.3-3a are applicable to Units 1 and 2, and pages 3.5.2-5b and 3.5.3-3b are applicable to Unit 3. These pages were provided to NRC by letter of January 5, 2006.

U. S. Nuclear Regulatory Commission April 6, 2006 Page 2 The evaluations requested in your November 1, 2005 letter are now completed and owner-approved.
The evaluations concluded that there are no adverse effects on the post-accident function of the new RBES strainers resulting from jel: impingement, pipe whip, or internally generated missiles.
Copies of the approved analyses were provided to NRC (Mr. Lenny Olshan) by email on March 27, 2006.
Th:is supplement to the August 18, 2005 LAR, requests approval of that amendment request for Unit 3. The Technical Specification retyped pages submitted with that request are applicable to this supplement as well.
These pages are provided in Attachment 1.
The following conclusions from the August 18, 2005 LAR remain unchanged:
- 1) Implementation of these changes will not result in an undue risk to the health and safety of the public.
- 2) There are no significant hazards associated with the supplement.
- 3) There are no adverse environmental effects associated with the supplement.
Pursuant to 10 CFR 50.91, a copy of this supplement is being sent to the South Carolina Department of Health and Environmental Control.
Approval of this LAR supplement is requested by April 28, 20016 to support the upcoming Unit 3 refueling outage. ONS requests an implementation period of 60 days.
If there are any additional questions, please contact Russell Oakley at (864) 885-3829.
Very truly yours,
