Dear Mr. Giambusso:
This is to inform you of Florida Power Corporation's current position on the re-evaluation of the p.obable maximum hurricane (PMH) surge height at the Crystal River Unit 3 Nuclear Plant. Meetings were held in Washington on February 2 and 15,1973, with members of your staff and consultants from the U.S. Army Corps of Engineers - Coastal Engineering Research Center. At the February 15 meeting, our con-sultants, Dames and Moore, presented new information regarding their analysis and also submitted their (heretofore proprietary) computer program for AEC/CERC verification and results of actual program runs to the AEC.
At meeting's end on February 15, we were advised by the AEC repre-sentative that four (alternative) courses of action were possible for resolution of the differences in predicted PMH surge height between the AEC and Florida Power Corporation:
1.
Florida Power Corporation accept the AEC position of 33.4 feet.
2.
AEC accept the Florida Power Corporation position of 29.6 feet.
3.
Based on the February 15 meeting input by Dames and Moore, Florida Power docket a position of 32.1 feet with proposed AEC acceptance.
4.
Delay the decision on surge height for six (6) months before AEC-CERC can complete review and assessment of Dames and Moore work - with no indication to what the final design surge height would reach.

Mr. A. Giambusso February 22, 1973 We wish to inform you of our decision to remain with 29.6 feet (original design height was 24.5 feet) as a conservative PMH surge height and feel that such a position is justifiably conservative based on the Dames and Moore work. We accept the alternative to have AEC-CERC evaluate the Dames and Moore efforts, but feel strongly that your six (6) month review schedule is inconsistent with the "overall licensing' schedule, possible backfitting of design and con-struction, and the high priority of AEC concern to resolve such issues.
Our consultants, Dames and Moore, advise us that they can, in approximately sixty (60) days, both confirm computer program differences relating to surge height prediction as compared to the AEC-CERC program e
and calibrate their analysis based on actual hurricane data. We feel that resolution of the surge be resolved within sixty (60) problem based on these facts can certainly to ninety (90) days. We would request that AEC-CERC agree to this same schedule.
We are most anxious to resolve this matter at the earliest possible date so that risk to the licensing and overall project schedule for Crystal River Unit 3 is minimized. We trust that the appropriate action and schedule can and will be imposed by all for final resolution of this matter in sixty (60) to ninety (90) days.
Very truly yours,
