SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REGARDING ENRICHMENT VALUES FOR NEW FUEL STORAGE*, SALEM NUCLEAR GENERATING STATION, UNIT NOS. 1 & 2 (TAC NOS. MA4691 AND MA4692)
Dear Mr. Keiser:
In a letter dated February 2, 1999, the Public Service Electric and Gas Company (PSE&G, the licensee) submitted an application for an amendment to the Technical Specifications (TSs) for Salem Nuclear Generating Station, Units 1 and 2. The proposed amendment would modify TS 5.6, "Fuel Storage, Criticality."
The U.S. Nuclear Regulatory Commission (NRC) staff is reviewing your submittal and has determined that additional information is required to complete its review. The specific information requested is addressed in the enclosure. In a telephone conversation with representatives of your staff, the NRC staff discussed this information and obtained agreement that PSE&G would provide the additional information requested within 45 days of receipt of this letter.
If you have any questions regarding this matter, please contact me at (301) 415-1457.
Docket Nos. 50-272 and 50-311

REQUEST FOR ADDITIONAL INFORMATION ENRICHMENT VALUES FOR NEW FUEL STORAGE SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2
- 1)
Two analytical techniques are used to determine the acceptability of storage of fuel assemblies with nominal enrichments greater than 4.65 wt% U-235. The first method is based on the reactivity decrease associated with the addition of Integral Fuel Burnable Absorbers (IFBAs). The second method uses the fuel assembly infinite multiplication factor (k-infinity) to establish a reference reactivity. The first method is incorporated into the technical specifications by specifying the number of IFBA rods required for fuel assembly storage. Since k-infinity will be used as an alternative method for determining the acceptability of fuel storage in the fresh fuel racks, why is there no k-infinity technical specification?
- 2)
The fresh fuel racks have been analyzed for both full density water flooding, where k-effective does not exceed 0.95, and for optimum low-density moderation conditions, where k-effective does not exceed 0.98. This is consistent with the NRC Standard Review Plan 9.1.1 and with the Improved Technical Specifications. The first criterion requiring k-eff to be less than or equal to 0.95 if fully flooded with unborated water has been incorporated in the technical specifications. Why is there no technical specification requiring k-eff to be less than or equal to 0.98 under the low-density optimum moderation accident conditions?
- 3)
The k-infinity of 1.480 was based on a 17x17 V5H assembly enriched to 4.65 wt%
U-235. Since the IFBA pin numbers have been changed to be consistent with the spent fuel pool storage requirements (i.e., 4.25 wt%), is this k-infinity value still valid or should it be modified to be consistent with a 4.25 wt% enriched assembly?
- 4)
Should the word "of' in technical specification 5.6.1.1.a be "or?
