Dear Mr. Zwolinski:
As part of the Systematic Evaluation Program, Dairyland Power Cooperative conducted a review of the seismic stability of the high pressure core spray (HPCS) piping system and the containment building overhead storage tank (OHST).

ew Mr. Jchn Zw211nski, Chisf Juna 3, 1985 Op2 rating Rtacters Branch #5 LAC-10933 The seismic analysis of the HPCS piping system was submitted as part of Reference No. 1.
Since that time, some pipe model discrepancies have been discovered. The HPCS piping system has been re-analyzed to incorporate these piping discrepancies. Enclosures No. 1 and 2 contain the revised HPCS suction and discharge piping system seismic analysis. The existing HPCS piping system remains capable of withstanding the SSE.
To comply with the commitments made in Reference No. 2, the OHST has been seismically analyzed. Enclosure No. 3 contains the summary of the OHST seismic analysis. This analysis concludes that the OHST is capable of withstanding the SSE.
If you have any further questions regarding these topics, feel free to contact us.
