s 7590-01 UNITED STATES NUCLEAR REGULATORY CCMMISSION FLORIDA POWER CORPORATION, ET AL.
DOCKET NO. 50-302 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from a requirement of 10 CFR 50.44(c)(3)(iii) to Florida Power Corporation (the licensee)., for the Crystal River Unit No. 3 Nuclear Generating Plant, located in Citrus Ccunty, Florida.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action: The exemption would permit the licensee not to install a reactor vessel head vent as required by 10 CFR 50.44(c)(3)
(iii).
The exemption is responsive to the licensee's applicatior for exemption dated October 22, 1984.
The Need for the Proposed Action: The licensee has performed tests using the Once-Through Integral System (OTIS) facility. The purpose of these tests was I
to determine if reactor core cooldown can be maintained in the absence of a vessel head vent to release noncondensible gases from the vessel during an i
accident. Based on results of the OTIS tests, the licensee concluded that a reactor vessel head vent is not needed since other high point vents can be used to release gases.
Furthermore, the licensee has committed to implement appropriate emergency procedures to assure reactor core cooling in the absence of a vessel head vent.

7590-01 Environmental Impacts of the Proposed Action: The proposed exemption, as supported by the licensee's test results and commitment, will provide assurance of reactor core cooling that is equivalent to that required by 10 CFR 50.44(c)(3)(iii) such that there is no increase in the risk of accidents at this facility. The probability of accidents will not be increased and the post-accident radiological releases will not be greater than previously determined, nor will the proposed exemption otherwise affect radiological plant effluents. Therefore, the Commission concludes that there are no significant radiciogical environmental imoacts associated with this proposed exemption.
With regard to potential nonradiological impacts, the proposed exemption involves feetures located entirely within the restricted area as defined in 10 CFR Part 20.
It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed exemption.
Alternative Use of Resources: This action involves no use of rescurces..not previously considered in the Final Environmental Statement (construction permit and operating license) for the Crystal River Unit No. 3 Nuclear Generating Plant.
Acencies and Persons Consulted: The Commission's staff reviewed.the licensee's recuest and did not consult other agencies or persons.
