AUG 0 41980 Docket No. 50-409 Mr. Frank Linder General Manager Dairyland Pcwer Cooperative 2615 East Avenue South Lacrosse, Wisconsin 54601 Gentlemen:
RE: LACROSSE Our letter to you dated January 15, 1979 requested that you initiate as part of the Systematic Evaluation Program (SEP) a program to demonstrate the seismic design adequacy of your f acility.
In relation to this request, we are aware of your efforts to develop a site specific ground response spectrum for your site; however, active structural / mechanical evaluations have not specifically been initiated.
You are requested to submit, by September 15, 1980, details of your plans for proceeding with a seismic evaluation program and provide justification for why you conclude that continued operation is justified in the interim until the program is complete.
Your submittal should address the secpe of review and evaluation criteria and pro-vide a schedule for completion.
The analytical portion of your progrsa should be conpleted no later than January 1,1982. Any modifications to the facility that may be necessary as a result of your evaluations should be installed by the following refueling outage, but no later than January 1,1983.
Any proposed changes to the facility as described in the safety analysis report shall be l
made in accordance with 10 CFR 50.59 of the Commission Regulations.
As a minimum, your program should provide for an evaluation of:
1-The integrity of the reactor coolant pressure boundary, 2.
The integrity of fluid and electrical distribution systems related to safe shutdown and engineered safety features, 3.
The integrity and functionability of mechanical and electrical equipment and engineered safety feature systems (including containment).
Although we have delayed until the and of 1980 a final decision relative to seismic input to maximize the potential benefits to be derived from use of site specific ground response spectra, we expect you to proceed with ycur seismic evaluation program.
Based upon input that we have received from the Lawrence Livermore Laboratory / TERA Corporation Site Specific Spectra Project, the I
Systematic Evaluation Program licensees, NRC consultants and other sources, we have concluded that the ground response spectra shown in the Attachment 1 is an f
appropriate level at which to initiate your evaluations.
Between now and the end of 1980 we olan to conplete add' tional work that will allow us to finali:e our dec'st on.
It does not.=aaa - l'kely that the ground response spectra shewn 80081100 Q
e..
4 ceb, Mr. Frank Linder in Attachment I will be modified to a large degree. Therefcre, we strongly recomend that ycu use this ground response spectrum in your evaluations.
The bases for our decision are docurented in At*.ach:aent 2.
Ycu are free to make an alternative proposal for use in the interim until the final NRC staff decisicn is rade.
We.ust e chasi:e that taking such an approach involves increased risk en ycur part because certain evaluatiens may have to be radene at a later ti:ne.
Fur.her:cre, limitaticns of NRC staff resources make review of alternative prepcsals imossible in the near term.
In accordance with 10 CFR 50.54(f) of the Cemissien's regulations ycu are requested to cub =it the information described above en the cates indicated above in order to enable the Co. mission to determine whether or not ycur license shcuid be cdified, suspended er reycked.
Sincerely, Darrell G. Qisennue, Director Divisica cf Licensing Office cf Nuclear Reacter Regulaticn
