Dear Mr. Johnson:
Reference (a) requested Rochester Gas-and-Electric (RG&E) to submit an ECCS evaluation that included the effects of Upper Plenum Injection (UPI).
The evaluation has been completed using Reference (b) methodology.
The attached report summarizes the evaluation and will be used to update section 15.6.4.2 of the Ginna UFSAR.
It is requested that this evaluation become the analysis of record with the startup of Cycle 23,. currently scheduled for May 3, 1993.
In order to use the methodology of reference (b), exemptions from two specific sections of 10CFR50 Appendix K are necessary because of the hardware configuration of upper plenum injection.
Those exemption requests are being submitted under separate cover.
Ver ruly yours, 13004'P
