SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTIriG AMENDMENT NO. 2 5 TO FACILITY OPERATING LICENSE NO. DPR-72 FLORIDA POWER CORPORATION, ET AL CRYSTAL RIVER UNIT 3 NUCLEAR GENERATING PLANT DOCKET NO. 50-302 Introduction By letter dated May 23, 1979, Florida Power Corporation (FPC) proposed changes to the Technical Specifications (TS) for Crystal River Unit No. 3 (CR-3). These changes would revise the FPC offsite organization and the unit in which maximum rate of chan;e of power is specified. Also by letter dated July 21, 1977, the licensee proposed to modify the format of a portion of the Environmental TS for clarity. We have evaluated the proposed changes.
Evaluation The revised offsite organization will establish a management position at the corporate offices of FPC which deals solely with operation of nuclear plants.
This position is the Manager-Nuclear Operations.
Previously the Nuclear Plant Manager and the fianager-Huclear Support Services reported to the Director-Power Production whose office was also responsible for non-nuclear related power pmduction operations.
In the modified organization, the Nuclear Plant Manager and the Manager-Nuclear Support Services report to the Manager-Nuclear Operations.
The revised offsite organization should enhance corporate level management attention to the operation of CR-3 and is acceptable.
By letter dated July 21, 1977, the licensee proposed a change to the format of the Environmental TS to more clearly define the functions and responsibilities of the Nuclear General Review Comittee in environmental matters. This change clarifies the Environmental TS and is acceptable.
Currently FPC is required to provide prompt notification to NRC of short term reactivity increases corresponding to a reactor period of less than 5 seconds.
Reactor period is the time required for neutron density (flux) to change by a factor of about 2.7.

()((,
. FPC has proposed to change the units for rate of change of power from seconds (reactor period) to decades per minute (startup rate) since startup rate meters, instead of reactor period meters, are used at the plant. The revised TS would require reporting a startup rate greater than 5.2 decades per minute.
Reactor period (T) and startup rate (SUR) are directly related by the formula:
SUR = 26.06 T
We have determined that the proposed change does not alter the rate of change of power required to be reported and is therefore acceptable.
Environmental Consideration We have determined that the amend at does not authorize a change in effluent types'or total amounts nor an increase in power level and will not result in any significant environmental impact. Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and, pursuant to 10 CFR 151.5(d)(4), that an environmental. impact statement, or negative declaration and environ-mental impact appraisal need not be prepared in connection with the issuance of this amendment.
Conclusion We have concluded, based on tb considerations discussed above, that:
(1) because the amendment does not involve a significant increase in the probability or consequences of accidents previously considered and does not involve a significant decrease in a safety margin, the amendment does not involve a significant hazards consideration, (2) there is reasorable assurance that the health and safety of the public will not be encangered by operation in the proposed manner, and (3) such activities will be conducted in compliance with the Commission's regulation:. and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
