STAFF SAFETY EVALUATION FOR EXTENSION OF THE LATEST CONSTRUCTION COMPLETION DATE FOR THE CALLAWAY PLANT, UNIT 1 Introduction The Nuclear Regulatory Commission (NRC) authorized the construction of the Callaway Plant, Unit 1 by issuing Construction Pernit No. CPPR-139 to Union Electric Company. The latest date for completion of the Callaway Plant, Unit 1 is December 31, 1983.

By letter dated October 28, 1983, Union Electric Company submitted an application for amendment of the construction permit to reflect the new " latest completion date" for Callaway Plant, Unit 1.

The applicant requested an additional time of 18 months for completion of construction.

This would extend the completion date to June 30, 1985.

In accordance with 10 CFR Section 50.55(b), the NRC staff, having found good cause shown, recommends that the latest completion date of June 30, 1985 be granted for reasons stated below.

Analysis Union Electric Company stated in the October 28, 1983 letter that the extension of time for completion of construction was needed because of the following:

1.

The exacting nature of the work during the latter stages of construction.

2.

Construction has not progressed as rapidly as projected, due in part to increasingly stringent quality requirements.

3.

Numerous changes and additional requirements for plant design and analysis have been incorporated, including those required by the Commission as a result of the Three Mile Islard accident and during the course of the NRC's regulatory review.

The NRC staff has reviewed the cause for delay stated in the October 28, 1983 letter and has concluded that the applicant has shown good cause for the delay in accordance with the requirements of 10 CFR Section 50.55(b).

The NRC staff recommends that the construction permit be extended an additional 18 months to provide for schedule delays as requested by the applicant.

. As a result of the review of the Final Safety Analysis Report to date and considering the nature of delays, the NRC staff has identified no area of significant safety consideration in connection with the extension of the con-struction permit completion date. This is the only change proposed by ohe applicant and the extension will not allow any work to be performed involving new safety information of a type not considered by previous Commission safety reviews of the facility and that is not already allowed by the existing con-struction permit. Therefore, the staff finds that (1) this action does not involve a significant hazards consideration, (2) prior public notice of this action is not required, (3) there is reasonable assurance that the health and safety of the public will not be endan construction completion dates, and (4)gered by the requested extension of the good cause exists for issuance of an Order extending the latest construction completion date.

C_coclusion Tne Commission's staff has reviewed the information provided in the applicant's submittal and has concluded that the factors discussed above are reasonable and constitute good cause for delay. Therefore, the NRC staff has concluded that the latest construction completion date for the Callaway Plant is reasonable and justifiable.

The NRC staff finds that this action does not involve a significant hazards con-sideration, and that good cause exists for the issuance of an Order extending the latest completion date for Construction Permit No. CPPR-139 from December 31, 1983 to June 30, 1985.

The NRC staff has determined that this action will not result in any significant environmental impact and, pursuant to 10 CFR 51.5(d)(4), an environmental impact statement, or negative declaration and environmental impact appraisal, need not be prepared in connection with this action.
