I NTRODUCTION 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, " Control of Heavy Loads at Nuclear Power Plants".
Scope This report is divided into two (2) parts. "Part A" addresses specific requirements set forth in Section 2.1 of Enclosure 3 to the NRC's letter as they pertain to the Reactor Buildings at McGui re Nuclear Station.
"Part B" addresses specific re-quirements set forth in Section 2.3 of the same enclosure.
PART A Initial Review Crane / Load List A list containing all load handling systems and their respective loads was compiled and compared to the Reactor Building General Arrangement drawings by station personnel in order to verify that the drawings correctly represented "as-built conditions".
Conditiens of Operation For the purpose of our review we broke the operating conditions in the Reactor Buildings down into four conditions.
Condi tion 1 (Full or Reduced Power)
During th!s condition the reactor is in operation.
All
, vi tal systems are requi red.
Condition 2 (Hot Shutdown)
In this condition the reactor has been shut down but the reactor coolant system is pressurized above 300 psig and its temperature remains above 200*F.
During this condition
~
all vital systems arc requiied.
Condition 3 (Cold-Shutdown, Fuel Loaded)
In this condition the reactor is completely shut down and the reactor coolant system depressurized allowing removal of the reactor head.
Fuel is present in the core.
During this condi tion only decay heat removal systems are needed.
9 y
n.---._. _.. -
7 Condition 4
( Cold Shutdown, Fuel Unloaded)
This condition is identical to Condition 3 except no fuel is present in the vessel.
No vital systems are required.
Review of Load Handling Systems Used During Different Conditions Of Operation Condition 1 & Condi tion 2 During these conditions miscellaneous hoists are used for minor repai r work or for obtaining cold-shutdo vn but do not handle heavy loads.
Operation of the Polar Crane is restricted as specified in Station Directive 3.3.6,
" Reactor Building Polar Crane and Auxiliary Hoist Operation".
Underdrce conditions a heavy load drop can not occur precluding the need to investigate further the load handling systems or operations during these conditions.
Condition 3 During this condition all load handling systems are subject to use.
All load handling systems will be reviewed.
Condition 4 A heavy load drop during this condition would have no impact on the station since the Unit is down with the fuel unloaded and out of the building.
For this reason it will not be necessary to review load handling systems and op-erations during this condition.
Based on this review, only load handling operations during Condition 3 requi re further investigation.
Development of Load Drop Areas Load drop areas were developed for each load handling system used during Condi tion 3 as shown on the attached General Arrangement drawings.
The load drop area of all cranes was defined as the area over which the hook may pass if trolley and bridge travel were unrestricted.
All load drop areas include an allowance for load shape and are projected to the. basement.
Locating Vital Systems in the Load Drop Areas
" Vital Systems" defined as those systems necessary for safe shutdown and/or decay heat removal, located within the load drop areas were identi fied and superimposed on the General Arrangement drawings.

Load Handlinq Systems to Receive Further Consideration The IIst of load handling systems with their respective loads was reviewed to determine which systems handle heavy loads (1500 lbs. or more).during Condition 3 The relevant drawings were then reviewed to determine which cranes or hoists handling heavy loads also contained vital systems and/or the reactor vessel in their load drop areas. These systems received further evaluation.
The renaining systems were eliminated from consideration as insignficant.
Summary of Initial Review Table i summarizes the results of the initial review of load handling systems in the Reactor Buildings.
This Table identifies cranes and hoists handling heavy loads during cold shutdown and indicates i f vital systems and/or the reactor vessel is located within thei r load drop areas.
Final Review
~
Scope The load handling systems identified'in Table I as handling heavy loads over vital systems and/or the reactor vessel at cold shutdown were rev;cwed for compliance with Section 2.1.3 of Enclosure 3 to the NRC's letter dated December 22, 1980 concerni ng NUREG-0612.
The results of that review are described in the following sections and summarized in Table ll.
l Safe Load Paths Safe Load Paths are explained in Table 11.
Station Directive 3.3 7, Handling of Heavy Loads,- has been impicmented to explain the purpose of these paths.
l i
Establishment of Load Handlino Operations Table 11 was prepared for each load handling system which is j
located over vital systems and/or the reactor vessel and summarizes l
the information requested in Sections 2.1-3c through 2.1-39 The l
table is self-explanatory.
Conclusion The initial review of load handling systems in the Reactor Buildings revealed a total of 31 cranes which handle heavy loads over vi tal systems and/or the reactor vessel.
Further investi-ation of these systems showed that they comply fully with all parts of Section 2.1-3 of Enclosure 3
'All information requested under Section '2.1 of Enclosure 3 for i
the Reactor Buildings is included in this report.

PART B Crane / Load Combinations Considered Cranes considered for this review are those operational during Condition 3 of the plant and identi fied in Table i of this report under the heading " Handles Heavy Loads and has Reactor Vessel in Load Drop Area".
The associated loads are found in Table ll of this same report.
Postulated Load Drops Only two (2) of the crane / load canbinations possible while the Unit is at cold shutdown will be considered because they envelope the others.
1.
The first accident consists of dropping the reactor head onto the vessel flange.
This accident could cause structural damage to the vessel and attached piping resulting in loss of cooling pater. (Criteria lil) 2.
The second accident consistsof an oblique drop of the reactor head onto the upper' internals.
This accident I
could damage fuel, releasing radioactive gases (Criteria
- 1) and result in increased gap activity above acceptable limits. (Criteria ll)
These analyses are scheduled to be completed in September of thi s yea r'.
The results will be forwarded to you at that time.

(1) These specifications do not apply to the design of monorails or jib cranes.
Our monorails and jib crancs are designed in accordance with the applicable AISC code and/or OSHA Code of Federal Regulations, Part 1910.179.
(2) The safe load path of a monorail can only be the vertical projection of the monorail on the underlying floor.
For this reason, it is unnecessary to perform this work.
(3) The safe load paths for these jib cranes can only be the vertical projec-tion of the radius of curvature on the underlying floor since the radius
' of curvature produces only one set path for egiupment that is being lifted.
For this reason, it is unnecessary to perform this work.
(4) There will be no safe load paths for this crane due to it requiring access to all parts of the Ice Condensers. For this reason, it is unnecessary to perform this work.
(5) The lifting device used in handling these loads consist of the appropriate size and number of chain-falls, chokers, and slings as determined by the rigger.
In making his selection, the rigger draws on his experience and the Ele-mentary and Advanced Rigger Training provided at the Duke Power Company Training Center.
Choker and sling sizing is determined by the estimated weight of the load.
If additional information is needed, the Riggers Hand-book is used. All lifts are made by qualified people who, by experience
. and/or training are cognizant in the movement of loads.
-(6) Each equipment load listed for the polar crane has a specific storage point.
The polar crane will lower the equipment to the same point each time.
For this reason, it is unnecessary to perform this work.
(7) The investigation of these special lifting devices is proceeding. The
_ results will be forwarded to you when the investigation is complete.
