i The Draft. Environmental Statement was prepared in accordance with the statement of general policy and procedure on implementation of the National Environmental Policy Act of 1969 as set out in Appendix D of the Commission's regulations, 10 CFR Part 50.

A notice of availability of the Draft Environmental Statement and the applicant's envirotunental report, and regr.ast for comuments from interested persons is being sent

- to the Office of the Federal Register for filing and publication.

A

. request for comments also is being sent to appropriate Federal, State and local agencies.

SUMMARY

-AND CONCLUSIONS

^

This Draf t Environmental Statement-was. prepared by the U. S. Atomic Energy Commis~sion,; Directorate of Licensing (staff).

1.

This action-is: administrative.

6 -

2.. Th'eL proposed: actions are the continuation of the provisional' construction permit.CPPR-51 and the issuance of an ' operating lJ license to the' Florida Power. Corporation 'for the startup and operation of ? Crystal River Plant, Unit No. 3, a nuclear-power-reactor located on 'a site already occupied by two operating.

oil-fueled ele.ctrical generating plants. The site.is on-the j-

- Gulf of Mexico _ in the State of Florida. and near the town of p

Crystal. River, Citrus County, (Docket No. 50-302).

Unit No. 3_will employ ~a pressurized water reactor to produce j

initially 2452 megawatts thermal (MWt). With the contribution from the' reactor coolant pumps added, a gross electrical output of 855 megawatts electric (MWe) will result. A design power '

level of 2544 MWt - (885 MWe) is anticipated at a future date and is con'sidered-in the assessments contained in this statement.

The exhaust steam 'will be cooled Lby once-through flow of water

~

I obt-.ned from' and discharged to the Gulf- ~of Mexico.

~

j.'

I 3._. Summary of ~ che cumulative ~ environmental impact and adverse effects of Units l', ~ 2 and 3:

l Land areas.d'.sturbed during construction of the station,

+

but not to be occupied by buildings or facilities, are l

.to be allowed!to-revert to a natural condition.

The annual ' loss of juve tile' and small finfish and shellfish

~

L

, on the:1ntake screens (now estimated at 36,000 lb for L

Units 1 and 2)-'will increase 'due to the increased. flow j

= volume.

0-Entrainment of passing drift organisms is anticipated and.

+

1100%' mortality of' these organisms during their passage '

i Lthrough th' condenser cooling system is assumed. 1 Total e

. plankton. populations in thel area are not expected to be -

appreciably affected.

At Jfull; power, ~ condenser -cooling water' heited to 14.5*F

~

(8.l*C) above inlet temperature will' be discharged 'at the-rate of 2940 cubic feet;per second 'at" thel shoreline of the Gulf of Mexico.:

-The heated wat'er will-be mixed with the Gulf water such L

that.the zone within which temperatures may exceed 4*F above ambient, while of greater extent.than that for Units 1 and 2 alone, is expected to be restricted to a

' volume having a surface extent of about 2300 acres; the corresponding ~ area within the 10*F isotherm would be about 500 acres.

Studies of the environment with Units 1 and 2 operating at historical-load factors, indicate a minor impact upon the benthic system due to thermal discharge.

If Units 1 and 2 operated at-full power, a major localized impact on the biota, including grasses. and benthic organisms, could I

be expected in an area of about 500 acres due to the thermal plume. ' With Unit 3, also in operation at full power, and l

with the discharge syr.iem proposed-by the applicant, the area of major localized impact would be expected to increase to' about 1500 acrec. These estimates are based on zones in which temperatures could exceed 95*F in most years.

' At times of high exit temperature, fish will probably find the discharge area unacceptable and avoid it.

I The impact of small amounts of chemicals upon living forms in the ecosystem should be negligible, either alone or in synergistic combination with ' thermal increases.

I l

A very low. risk of accidental radiation exposure to nearby i

residents wi:1 be created.

L No significant environmental impacts are anticipated from l

l normal operational releases of radioactive materials. The l

estimated dose to the population within 50_ miles from opera-l

' tion of the station'is 0.14, man-rem per year.

)

.4.

Principal alternatives considered:

Abandonment of the facility, including consideration of the I

use of 'an alternative : fuel as a' power source rather than nuclear fuel.

Extension of the discharge canal as a means for directing the plume away from the nearshore area.-

)

i

. Dilution as'an alternative heat dissipation scheme.

Supplementary cooling as a heat dissipation method.

~

Closed-cycle cooling systems as a heat dissipation method.

Mayor', Crystal River, Florida f

$his statement was' made available to the public, to the Council 6.

on Environmental Quality, and to the other specified agencies in l

September 1972..

7.

On the basis of the analysis and evaluation set forth in this statement, af ter-weighing the ~ environmental, economic, technical, and other benefits of' Crystal River Unit 3 against environmental cos ts. and ' considering available alternatives,' it is concluded

~

that the actions called for are:

a.

The continuation 'of. construction permit CPPR-51, and

)

Eb'.. The issuance : of an operating license for the facility subject

~to:the following conditions for protection of!the environment:

,i -

(1) Initiate ' action to alleviate the major Icen11 zed impact of the thermal plume by. extension of the discharge canal i

to deeper water :or other means wh'ich' might result in lesser; environmental icpact. :Such actio'n should-include necessary engineering design;and studies ' to' determine the

c'onfiguration and environmental impact' associated with-a modification. The results of this effort must be avail-able so that - appropriate reviews' and. implementation can l=

"be accomplished prior to full power' operation of Unit 3.
