SOUTH TEXAS PROJECTc VNIT 1 DOCKET NO.-50-498 NOTICE OF ENVIRONMENTAL ASSESSMENT AND q

FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Comission (the Commission) is considering

^

issuance of a one-time exemption from a portion of the requirements of Appendix J of 10 CFR Part 50 to the Houston Lighting & Power Company, acting for itself and for the City of San Antonio (acting by and through the City Public Service Board of San Antonio), Central Power and Light Company, and the City of Austin, Texas (thelicensee),fortheSouthTexasProject(STP) Unit 1locatedin 1

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

Section III.D.3 of Appendix J,10 CFR Part 50, states that " Type C tests shall be' performed during each reactor shutdown for refueling but in no case at intervals greater than 2 years". The licensee in its letter of Jan:w

  • D, 1990 requested that the Type C tests required to be performed durir.3 e.. second refueling outage be deferred until the third refueling outage.

Becau,e the

.second refueling outage-is scheduled to occur in April 1990, six months after

- first refueling outage, conducting the Type C tests during the third refueling outage (April-1991) would be a test interval of 18 months, which is within the

)

interval stated in Section III.D.3.

a Need for Proposed Action:

f The proposed one-time exemption is needed because of the brief time interval (six months) between completion of the first refueling. outage in October 1989 and the second refueling out69e scheduled for April 1990.

'Further, the results Of Type C testing conducted during the first refueling outage do not indicate that an increased testing frequency is required.

Literal compliance with the regulation would lead to increased occupational exposure.

Environmental Impact of the Proposed Action:

Tne proposed one-time exemption to 10 CFR Part 50, Appendix J.

i Section 111.D.3 will not-increase to greater than previously determined the prchability of accidents and post-accident radiological releases, nor otherwise l

affect radiological plant effluents. Type C tests were successfully conducted t -.

L six r.onths before the presently scheduled second refceling outage. Therefore.

-the Comission concludes that there are no significant radiological environ-nental impacts associated with this proposed one-time exemption.

With regard to potential non-radiological impacts, the proposed one-time exemption involves features located entirely within the restricted area as L

defined in 10 CFR Part 20. They would not affect non-radiological plant

. effluents and would have no other environmental impact. Therefore, the Comission concludes that there are no significant non-radiological environ-t mental impacts associated with the proposed one-time exemption.

L '

' Alternatives to the Proposed Actions:

The principal alternative to the proposed actions would be to deny the i<

requested one-time exemption. This would result in increased costs and occupational v

'~ exposure.

The NRC did not consult other agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT:

Based upon the environmental assessment, we conclude that this action will not have a significant effect on the quality of the human environment.
