Docket 50 285 Gentlemen:
SUBJECT:
Fort Calhoun Station Quality Assurance file Room in accordance with 10 CFR 50.54(a)(3) Omaha Public Power District (0 PPD) is submitting a citrification to a commitment concerninq the qualifications of the fort Calhoun Station Quality Assurance (QA) Recorcfs Storage f acility.
This clarification could be interpreted as a reduction in a commitment, therefore, OPPD requests NRC approval prior to implementation.
10f1(llfICAT IRM.. CME OPPD wishes to clarify a commitment to ANSI N45 3.9 - 1979 contained in Appendix A of the Updated Eafety Analysis Repot (USAR) related to the wind loading requirements for the Fcrt Calhoun St a lon Quality Assurance file Room. ANSI N45.2.9 - 1979 requires that the QA records facility be constructed in a manner which protects the QA records frcm " natural disasters such as winds."
OPPD is preposing to revise Append!x A to clearly state the aaximum wind velocity that the QA file Room is designed to withstand.
EfASEN FDR CHAfg The QA file Roota at fort Calhoun Station currently is located within a Class I structure (Auxiliary Building) designed to withstand a tornado with a maximum wind velocity of 300 miles per hour (USAR Section 5.11.3.1. A new QA File Room has been constructed in the Administration Building)at tne fort Calhoun Station which is not a Class I structure.
As ANSI N45.2.9 - 1979 does not statt the design requirements for natural disasters, OPPD is proposing to define the design maximum wind velocity for the QA file Room as 110 mph. Approval of the clarification will allow use of the new QA file Room in the Administration Building.

BMIS FOR CONCLUSION THAT THE CHANGE SAUSFIES PREVIQUS CDMMITHENTS The{,oposedchanetoAppendixAoftheUpdatedSafetyAnalysisReport (USA will clari that the QA file Room can withstand a maximum wind velocsty of 110 rap.
The maximum wind velocity of 110 miles 1er hour was calculated for the new QA File Room based upon the Steel Deck, nstitute and Uniform Building Code criteria.
As stated in USAR Section 5.4.6, the fastest wind at the site location for a 100 year period of murrence is a 90 moh basic wind at 30 feet above ground level.
Therefor, the new QA File R90m is well within the design basis wind velocity requirements for the site location.
A QA File Room does not fulfill a safety related function and does not meet the criteria of Regulatory Guide 1.117 Tornado Design Classification, File Room is located within a Class I structure capable of
" as a structure required to withstand a tornado. Although the current QA withstanding the effects of a tornado, it is OPPD's position that there-are no rcquirements in ANSI N45.2.9 - 1979 for a QA File Room to withstand tornados.
Therefore, OPPD has concluded that the QA File Room will continue to meet the requirements of 10 CFR Part 50, Appendix 8, Section XVil, on the storage of quality assurance records.
Attached is a proposed marked-up change to Appendix A of the USAR.
If you should have any questions, please contact me.
