Dear Mr. Denton:
Please find attached Duke Power Company's response to Section 2.1 of of the December 22, 1980 generic letter concerning NUREG-0612, Control of Ileavy Loads at Nuclear Power Plants. Wock in assimilating the response to Sections 2.2 and 2.3 is still in progress.
A final response containing the rest of the necessary information will be pro-vided by June 4, 1982. Please excuse this delay as there were some problems involved in processing this information.

SPENT FUEL POOL AREA CONTROL OF HEAVY LOADS (NUREG 0612)

INTRODUCTION The information presented in this report is the result of a detailed evaluation of load handling systems as. requested by the NRC in their letter dated December 22, 1980 concerning NUREG 0612 "The Control of Heavy Loads at Nuclear Power Plants."
SCOPE This report addresses the requirements set forth in Section 2.1 of Enclosure 3 of the NRC's letter as they pertain to the Auxiliary Buildings and Spent Fuel Pool Areas at the McGuire Nuclear Station.
INITIAL REVIEW Crane / Load List A list containing all load handling systems ar.d their respective loads was compiled and compared to the Auxiliary Building and Spent Fuel Pool Area General Arrangement drawings by Station personnel in order to verify that the drawings correctly represented "as-built" conditions.
Development of Load Drop Areas Load drop areas were developed for each load handling system as shown on the attached General Arrangement drawings.
For cranes, the load drop area was defined as the area over which the hook may pass if trolley and bridge travel is unrestricted. The load drop area for monorails was taken to be the vertical projection bf the monorail on the floor. All load drop areas include an allowance for load shape and are projected to the basement.
Load Handling Systems to Receive Further Consideration The list of load handling systems with their respective loads was reviewed to determine which systems handle heavy loads (1500 lbs. or more).
Systems handling heavy loads received further evaluation. The remaining systems were eliminated from consideration as insignificant.
Locating " Vital Systems" and Spent Fuel in the Load Drop Areas
" Vital Systems," defined as those systems necessary for safe shutdown or decay heat removal, lying in the load drop areas of heavy load handling systems were identified and superimposed on the General Arrangement drawings.
For evaluation purposes, it was assumed that spent fuel could be located anywhere in the Spent Fuel Pool, eliminating the need to detail the exact location of the fuel on the drawings.
Any load handling system operating over the Spent Fuel Pool was assumed to be operating over spent fuel.
Summary of Initial Review Ta ele I summarizes the results of the initial review of load handling systems in the Auxiliary Buildings and Spent Fuel Pool Areas.
This Table identifies heavy load handling systems having vital systems or spent fuel in their load drop areas which will require further consideration.
1 I
FItlAL REVIEW Scope The load handling systems identified in Table 1 as handling heavy loads ove vital systems or spent fuel will be reviewed for compliance with Section 2.1-3 of Enclosure 3 to the flRC's letter dated December 22, 1980 concerning NUREG 0612.
Work is in progress on this review.
