Dear Mr. Goldberg:

Su5 ject: Licensino Require 1ents for Pending Construction Permit and Manufacturing License Applications - Application of the Final Rule to Allens Creek Huclear Generating Station, Unit 1 The Comission issued its Final ilule on Licensing Requirements for Pending Construction Permit and Manufacturing License Applications on January 12

-1982 (Federal Register at pages 2286-2305 on Friday, January 15,1982).

The rule will be effective on February 16, 1982 and applicable to construction peraf t and manufacturing license appitcations pending on that date. The Final Pule includes some changes to the proposed requirenents contained in NUREG-0718, " Licensing Requirements for Pending Applications for Construction -

Pemits and Manufacturing License," dated March 1981 and NUREG-0718, Revision 1 dated June 1931.

The NRC Staff re/iew of Ilouston Lighting & Power Comnany's (HL&P) apDlica-tion for a pomit to construct Allens Creek Nuclear. Generating Station, Unit 1 was completed by issuance of the Safety Evaluation Report, Supplementi Ho. 4, NUREG-0515 in October 1931. The staff's analysis of infomation

(

submitted by llL&P to show compliance with the requironents of NUREG-0718, Revision I was contained in the Safety Evaluation Report, Supplement No. 3 issued in July 1981.

In Section 1.1 of Safety Evaluation Report, Supplement i

No. 4, the staff provided additional discussion pertaining to 'your continuing N.

studies on hydrogen source term criteria, systen actuation criteria L(including inadvertent actuation), contaiment pressurization and equipment survivability.

X The staff also delineated conditions that it recomended for issuance of a construction pemit to ensure periodic sutnittal of status reports and N

natntenance of the capability of incorporating any of the alternative systems N.

in the final design.

y We have cr*apared the results of our review as reported in the Safety Evaluation Report, Supplements 3 and 4, with portions of the Final Rule that have been changed from the proposed requirements of MUREG-0718..He have concluded that your cocMitments and plans, together with our reconnended construction '\\

permit conditions are in accordance witu the requireuents of the final rule.

Those conditions include specified periodic reporting requirements and ualn-tenance of capability of incorporating alternative inydrogen control systems in the final design until the staft has reviewed and accepted your final report. On that basis we conclude that the requirecents of 50.34 (f)(1)(xii) for perforcing an evaluation of alternative hydrogen control systens have been ux:t.

As indicated in Section 1.1 of the Safety E. valuation Report, Supplement No.4, equipment survivapility is an issue to be addressed in your progran on the hjorogen control systems. On this basis we concluae that the requirements of 50.34 (f)(2)(1x)C have Deen n.et.

These requirebents are for providing reasonable assurance that equipment necessary for achieving and maintaining safe shutdown of the plant and maintaining containment integrity will perform its safety function during and af ter being exposed to the environmental concitions attendant with the release of hydrogen generated by the equivalent of a 100t fuel clad oetal water reaction including the environmental conditions created Dy the activation of the hydrogen control system. Other changes in the final rule either do not apply to Allens Creek or do not represent substantive issues with respect to Allens Creek.

Enclosed for your information are copies of the referenced Federal Register notice and ubkEG-0718, hevision 2.

Please advise us by February 19, 1982, if.your review results in identification of a need for any clarifying changes in your application.

Sincerely, S
