', i REQUEST FOR ADDITIONAL INFORMATION RELATED TO PRESSURE-TEMPERATURE LIMITS IN TECHNICAL SPECIFICATIONS ENTERGY OPERATIONS. INC.

l GRAND GULF NUCLEAR STATION. UNIT 1 DOCKET NO. 50-416 The following request for additional informations is concerned with the licensee's letters dated May 2, 1996, (GNR0-96/00035) and October 22, 1996, (GNRO-96/00120), for an amendment to the pressure-temperature limit curves in I the Technical Specifications (TSs) for Grand Gulf Nuclear Station, Unit 1. i

1. General question: Provide the methodology used to generate pressure-temperature (P-T) limits for the bottom head and the feedwater nozzle. l 1

2. Page 2 of 8:. The detailed information needed to calculate the reported adjusted reference temperature (ART) of 57.57 DEG F can be found in your letter of Mgy 2,1996, from which the internal-diameter (ID) fluence of 2.5E18 n/cm at 32 EFPY was reported. The May 2, 1996, letter indicated that this fluence value was from General Electric (GE) Report EAS-35-0387 (April 1987). The ID fluence value at 2 EFPY in the NRC reactor vessel l integrity database (RVID), is 3.11 n/cml, which was reported to be the i

)

latest data in your letter dated May 5,1994, in response to the NRC close-out letter regarding GL 92-01. The latter value is in line with all your recent submittals. Resolve this discrepancy. ,{

3. Page 3.4-31 to 3.4-35 of the Technical Specifications: Change of fluence j should not affect the P-T limit curves which are controlled by the  !

feedwater nozzle, as evidenced in the five figures of Figures 3.4.11-1. i Explain the discrepancy between the current curves that are controlled by the feedwater nozzle for 10 EfPYs and the proposed curves that are controlled by the feedwater nozzle for various EFPY intervals.

4. Page 3.4-31 to 3.4-32 of the Technical Specifications: Change of fluence should not affect the P-T limit curves for the bottom head; however, the i curves vary among the current Figure 3.4.11-1 and the first two figures  !

of the proposed Figure 3.4.11-1. Provide an explanation for this variation.
