Dear Mr. Eisenhut:

Re: St. Lucie Unit 82 Docket No. 50-389 Turtle Barrier Cost"Estimate Attached please find cost estimates and related backup information for installing turtle barriers on the ocean intake velocity caps at the St. Lucie Plant. The information is being provided in response to your recent inquiries in connection with the Final Environmental Statement.

We understand that the estimates are required only to provide an order of magnitude indication of the costs associated with installing turtle barriers. Additionally, it has been determined that the most signifi-cant cost item will result from plant outages required for installation and maintenance of a barrier system. Therefore, the attached estimates have been developed considering only outage costs and do no include any capital cost for materials, installation and maintenance.

Very truly yours, Robert E. Uhrig Vice President Advanced Systems 8 Technology REU/RAK/ga Attachment qgoI S cc: J. P. O'Rei lly, Region II Harold F. Reis, Esquire eSOS lt0+yl PEOPLE... SERVING PEOPLE Q

L-82-196 ATTACHMENT ST. LUCIE UNIT 2 TURTLE BARRIER COST ESTIMATES Two cost estimates have been developed for the installation of turtle barriers on the ocean intake velocity caps at the St. Lucie Plant as fol ows:

1 I) Cost estimate for installing a test turtle barrier.

panel on one side of any one of the three velocity caps.

2) Cost estimate for installing a full set of turtle barriers on .each of the three velocity caps.

Due to time restrictions, the cost estimates have been developed con-sidering only the costs associated with plant outages that will be required for the installation and maintenance of the barriers. It has been. determined that the items not considered (such as capital costs for materials, installation, maintenance, etc.) would have little effect on the total estimated cost of the barriers.

It should be noted that the cost estimates are extremely sensitive to the basic assumptions and variable parameters used. An attempt has been made to use the most reasonable assumptions and parameters in the development of these cost estimates. Some of the variables that were considered relate to:

1) Escalation of replacement power costs over the life of the plant.

2) Discount rates used to calculate present values.

3) Length and frequencies of plant outages.

Based on the above, the following are the present value estimated costs of the turtle barriers:

1) Test barrier panel: $ 8,650,000.

2) Full set of barriers on each of the three velocity caps: $ 62,400,000.
