facility described in the application and the hearing record, in ac-cordance with the principal architectural and engineering criteria

4) as it applies to the postulation of longitudinal and circumferential pipe breaks in the Reactor Coolant System primary loop piping (hot leg, cold leg, and crossover leg piping).

In order that activities related to this issue (e.g. Class 1 piping functionality - SER Open Item #5) are not affected, we request written noti-fication, that our exemption request has been granted by July 31, 1985.

The application fee (150.00) required by 10CFR170.12(c) is remitted herein.
