'UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 October 22, 1984 Docket No. 50-244 MEMORANDUM FOR:
Harry Kister, Chief Projects Branch ¹2 Division of Project and Resident
- Programs, Region I FROM:
SUBJECT:
Re:
Walter A. Paulson, Acting Chief Operating Reactors Branch ¹5 Division of Licensing, Office of Nuclear Reactor Regulation INTERPRETATION OF TECHNICAL SPECIFICATIONS, MOYEMENT OF AUXILIARYBUILDING CRANE OYER FUEL STORAGE RACKS (SECTION 3.11.3)
R.
E. Ginna Nuclear Power Plant This memorandum documents discussions between G. Dick (ORPM), S. Collins (Chief., Section
¹2C) and W.
Cook (Ginna RI) regarding the interpretation of Section 3. 11.3 of the Ginna Technical Specifications (TS).
Section 3.11.3 states that:
The trolley of the auxiliary building crane shall never be stationed or permitted to pass over storage racks containing spent fuel.
There are two aspects to the interpretation which were discussed:
1)
The TS applies only to the lifting and movement of heavy loads (loads in excess of 1500 pounds).
When the crane is used for loads less than 1500 pounds, the loads and/or trolley may pass over spent fuel.
2)
In the submittal requesting approval of modifications to the spent fuel pool racks, the licensee noted that during lifting and movement of the westmost racks of the spent fuel pool, there was a possibility that the load could swing slightly so as to be suspended above part of a rack containing spent fuel:
While the load would be above the rack, it would not be above the fuel in the rack, and the licensee would make every effort to prevent the s'uspended rack from passing over an inplace rack.
.However, the distances between adjacent racks are very small and during the lifting the rack could swing slightly, which would bring it over an adjacent rack.
As a compensatory action, the licensee proposed to empty the three rows in the racks on either side of the rack being moved.
Then if the suspended rack were dropped, it would not fall on any fuel assemblies.
The licensee also noted that with three empty rows in adjacent
- racks, the outermost edge of the trolley would pass over a row containina snI nt fuel.

Ha'rry Kister, October 22, 1984 It was concluded that removal of fuel from the three rows on either side of the moving rack was sufficient protection in the event that the moving rack (a) swung over an adjacent rack and, (b) fell. It was "also noted that TS Section 3.11.3 applies to the heavy loads themselves
'nd movement of the trolley over spent fuel while lifting heavy loads is not in it self a violation of the TS.
In addition to the discussions with your staff, these interpretations were also discussed with members of the cognizant review branch in NRR (Auxiliary Systems Branch) and the licensee.
The licensee will be requesting a change to the TS to make them consistent with the interpretation discussed earlier in this memo.
