Subject:

Oyster Creek Nuclear Generating Station Docket No. 50-219 Response to Generic Letter 84-24 In accordance with your letter of December 27, 1984, GPUN has in place and is implementing an Environmental Qualification Program which to our knowledge satisfies the requirements of 10CFR50.49. In a recent submittal dated February 22, 1985, GPUN provided qualification status for each of the components on Oyster Creek Environmental Qualification Equipment Master List (EQEML) and Justifications for Continued Operation for those components requiring further qualification efforts. The February 22, 1985 letter also requested schedular extensions for certain pieces of equipment. The EQEML identifies components which are needed in order to provide a qualified path to safe shutdown as well as equipment required to be qualified for post accident monitoring (RG 1.97) and other plant specific requirements.

Further, GPUN has reviewed the I&E Bulletins and Notices listed in your letter of December 27, 1984. Sunnary information on relevance is provided in ATTACHMENT 1. Additional infonnation concerning the relevant Bulletin / Notices is contained in the respective EQ file.
