UNITED STATES NUCLEAR REGULATORY COMMISSION Docket Nos. 50-272 and 50-311 WASHINGTON, D.C. 20555 March 9, 1993 LICENSEE:
Public Service Electric and Gas Company FACILITY:
Salem Nuclear Generating Station, Units 1 and 2
SUBJECT:
MEETING
SUMMARY
, RERACKING SPENT FUEL POOLS AT SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2 (TAC NOS. M85797 AND M85798)
On March 4, 1993, a meeting was held between Public Service Electric and Gas Company (the licensee) and the NRC staff to discuss the content of the application to rerack the spent fuel pools (SFP) at Salem 1 and 2.
Background
The current SFP at Salem have 1170 cells each for storing fresh or spent fuel.
At the current rate of spent fuel discharge and maintaining the ability to discharge one full core, the SFP will be filled by 1998 and 2002 for Salem 1 and 2, respectively.
The reracking will expand the existing SFP capacity to 1632 cells each.
This will provide storage, while maintaining the ability to discharge one full core,.until 2007.and 2011 for Salem 1 and 2, respectively.
Summary The current SFP have racks that were designed by Exxon and installed in the early 1980s.
The racks were designed such that fresh fuel up to 4.55 wt. % U-235, with abso~bers installed, could be stored in any array within the SFP.
This configuration is referred to as a one region SFP.
The individual cells have an inner shroud of stainless steel, a center sheet of aluminum clad boron carbide, boral (used for criticality control), and an outer shroud of stainless steel.
Some cells have experienced swelling of the inner shroud caused by the hydrogen gas buildup from the corrosion of the aluminum in the boral poison plates.
Before deciding to rerack the SFP, the licensee studied other options available for the storage of spent fuel, including: fuel pin consolidation, dry cask storage and the use of Hope Creek 2 facility. The results confirmed that, for the near term, reracking the two Salem SFP was the most economical and risk free option.
The new SFP configuration will have two regions.
Region 1 will consist of 3 of the existirig racks (300 cells) that will be used to store fresh fuel as well as spent fuel.
In this region, any array of fresh fuel will be acceptable.
Region 2 will consist of 9 new racks (1332 cells) that will be limited to the storage of spent fuel with a burnup of at least 38,000 Mwd/mt.

I The additional space is achieved by changing the pitch of the cells. The old racks had a pitch of 10.5 inches while the new racks will have a pitch of 9.05 inches.
Baral is still used for criticality control between the cells, however, the cells are of the vented design, essentially eliminating the swelling problem experienced in the current racks.
The application will use existing analytical tools to develop the licensing package.
The most significant points of the reanalysis to be included in the licensing package are:
- 1.
The decay heat calculations will use the decay times specified in the technical specifications before fuel movement, or a change to the technical specifications will be requested to incorporate the times used in the analysis.
- 2.
The effects of placing the new racks close to the SFP walls will be analyzed from a dose stand point (on the other side of the wall) and a criticality stand point.
- 3.
The racks will be designed for twice the mass of the existing*fuel elements in each cell. This will allow for consideration of storing consolidated fuel in the new racks without any further modification.
- 4.
A complete criticality and thermal hydraulic analysis.
It is expected that the SFP cooling system will not have to be modified to accommodate the additional heat load.
- 5.
The fuel handling crane, which has a 5-ton limit will be upgraded or replaced.
The old racks weigh 17 tons each and the new racks weigh 10.5 tons each.
The fuel handling crane will be used to remove the old racks and install the new racks in the SFP.
The licensee and their contractor (Holtec) is evaluating the approach to be taken.
- 6.
A complete seismic analysis, static and dynamic, of the new racks in the SFP.
The licensee has selected Holtec as the primary contractor for the licensing package development.
The racks will be constructed by UST&D in Pittsburgh, PA.
The licensee expects to submit the licensing package by the end of April 1993.
Approval from the NRC will be requested by April 1994.
