Dear Dr. Uhri9:
Me have reviewed your January 8, 1981 (L-81-8) proposed change to the St. Lucie Unit 1 Alternate Heat Sink Technical Specificatfons.
He have determined that the information'dentifiedwe.'he enclosure is necessary to complete our review.
Please provide this information by June 25, 1982.
The reporting and/or recordkeeping requirements contained in this re request affect fewer than ten respondents; therefore, OI1B clearance is not required under P.L.96-511.
Sincerely, Or)glnal signed by:
Robert A. Clark, Chief Operating Reactors Branch 03 Division of Licensing

RE UEST FOR ADDITIONAL INFORMATION We find unacceptable the licensee's deletion of the limitations on maximum water temperature in Technical Specification 3.4.7.5.
Furthermore we believe the limit should be 95 F instead of 96 F.
More certainty might be attached to the licensee's assertion of the low likelihood of intake canal temperatures exceeding 95oF if results from the ongoing temperature monitoring in the intake canal are presented.
The presentation of this data might also show the relative effect of additional heating of intake water due to recirculation.
The potential for recirculation may have been one of the primary reasons for imposing this Technical Specification.
We are also concerned about the potential for high ambient temperatures in Big Mud Creek (the alternate source of emergency cooling water),
although this was not directly addressed in the subject Technical Specification.
Unless it can be demonstrated otherwise, we must assume that ambient temperatures of 95 F or greater in Big Mud Creek may occur during the life of the plant.
We are assuming that water with an ambient temperature greater then the design inlet temperature of 95oF would not provide adequate cooling to get the plant into a safe shutdown condition.
We request that the licensee do one of the following:
(I) demonstrate that an ambient water temperature high enough to compromise safe shutdown is not a credible event in both alternate water sources during the life of the plant; or (2) revise the proposed Technical Specification to include temperature monitoring of both water sources with appropriate action identified when a specific temperature is exceeded; or (3) demonstrate that ambient water temperature, in one water source, high enough to compromise safe shutdown is not a credible event during the life of the plant and provide a revision of the Technical Specifications as indicated in (2) above for the other water source.
