OCT 1 1987 Docket No.:
50-206 LICENSEE: Southern California Edison Company FACILITY: San Onofre 1 SUBJECT
SUMMARY
OF MEETING HELD SEPTEMBER 25, 1987 REGARDING THE RELOCATION OF SPENT FUEL FROM SAN ONOFRE, UNIT 1 TO UNITS 2 AND 3 In the afternoon of 25 September 1987, representatives of Southern California Edison Company (SCE) met with members of the NRC staff to present and discuss their general concepts regarding the transport of spent fuel from the fuel storage pool at Unit 1 to the pools at Units 2 and 3.
The meeting was held in Room 110 of the Phillips Building in Bethesda. is the list of attendees.
Jack Rainsberry of SCE presented a description of the equipment and procedures used in the past for moving spent fuel from the spent fuel pool at Unit 1 to the railroad loading area. The procedure involved moving one assembly at a time in a small shipping cask set vertically on an air supported device (like a hovercraft) that moved on a concrete pad, propelled by a motor driven donkey engine and guided by a rail set into the concrete.
The device preforms well for the movement of small quantities of fuel but will be too slow for the movement of large numbers of fuel assemblies as is planned during the reload outage scheduled for June of 1988. The Unit 1 pool is nearly full and its capacity is insufficient for the fuel that will be removed from the reactor next June. SCE's desire is to use a larger shipping cask that will hold a minimum of seven assemblies and be transported by a gantry crane-from which it will be supported and to which it will be attached for increased stability during transit. Enclosure 2 is a copy of their presentation viewgraphs.
Units 2 and 3 are already licensed to store fuel from Unit 1 but the procedures for moving and handling fuel have not yet been approved by the NRC. Some safety related equipment and cables will be put in jeopardy during portions of the transport operation.

-2 On the surface, SCE's proposed facilities, equipment and procedures appeared to be appropriate and adequate, however, the licensee was encouraged to submit for staff approval a formal request to amend their license.
Subsequent to the actual meeting, the staff developed the position that, because a postulated drop of the cask can endanger safety related equipment, the licensee should commit to cask movement only in the cold shutdown/
refueling modes unless a strong argument can be made to justify cask movement during operation at power.
