Subject:

Application for Amendment to Facility Operating License, Revision to Reactor Coolant System PCS) Pressure and Temperature Limits Report (PTLR) Administrative Controls Requirements, September 29, 1997.

Dear Mr. Vissing,

l By the above reference, RG&E submitted a license amendment request (LAR) related to the Ginna Station Pressure and Temperature Limits Report (PTLR). During the performance of the NRC review, several errors and questions were identified. Therefore, attached please find the necessary corrections and clarifications to the September 29th LAR. These are provided in Enclosure 1 to this letter and summarized below:

Attachments II and III are revised to correct several typographical errors (i.e., ensure consistency between the two attachments) and to reference this document since minor errors within the low temperature overpressure protection (LTOP) methodology are also corrected by this letter.

Sections 2.2, 2.3.1, and 5.0 of Attachment IV are updated to: (a) reference the calculation which specifies the LTOP enable temperature; (b) correct a typographical error in Reference 3; and (c) reference this letter for reasons as described in 1 above.

Attachments V and VI are revised to delete the last paragraph of Section 3.3 and to modify the last paragraph of Section 3.4 to clarify the technical specification restrictions on reactor coolant pump starts.

These revised pages should be, substituted for those submitted in the referenced LAR 97i0150244 97i008 PDR ADQCK 05000244 P PDR II!Illllllllllllllllllllllllllllillllll

A questiqn was also raised with respect to whether the LTOP enable temperature was actually specified within Attachment VIIof the September 29th LAR and whether this temperature was also a limitation for reactor coolant pump (RCP) starts. RG8'cE had previously submitted a calculation which determined a LTOP enable temperature of a 306.3'F (see April 24, 1997 LAR, Attachment VII). This calculation remains valid since the heatup and cooldown curves from which the enable temperature is derived remain unchanged. A copy of this analysis is also being provided within this submittal. With respect to RCP starts, Ginna Station Technical Specifications LCO 3.4.6, Note 2 and LCO 3.4.7, Note 3 prohibit RCP starts below the LTOP enable temperature unless the secondary-to-primary temperature difference is < 50'F or the pressurizer water volume is < 324 cubic feet (38% level).

Very t y yours, Robert C. Mecredy Subscribed and sworn to before me on this 8th day of October 1997.
