CONTROL OF HEAVY LOADS IN CRITICAL LIFTING ZONES - NUREG 0612 1.0 SCOPE This instruction provides requirements for the control of lifts greater than 2,000 pounds (1 ton), made in the auxiliary building (El. 734), or in the upper compartment of units 1 and 2 reactor buildings in the areas designated as the critical lifting zones (CLZ). The CLZ's are defined in this instruction as the following areas (see the attached
~
refuel floor sitdown drawing).
1.
The region, defined as the reactor building CLZ, inside the polar crane wall of the upper compartment when at least one of the I
horizontal reactor well missile shields has been removed.
2.
The region, defined as the spent fuel pit CLZ, within 15 feet of the spent fuel pit when spent fuel is in the pit.
3.
The region, defined as the auxiliary building CLZ, within 15 feet ~
of the RHR and containment spray heat exchanger hatches when the I
hatch plugs have been removed and the heat exchangers are in service.
I This instruction does not apply to lifting of new o'r spent fuel assemblies using the manipulator crane or spent fuel bridge.

(MI-9.1, 9.2; MSL-A37, A50; OTGL-A3) 3.0 PREREQUISITES I-NOTE: The following prerequisites shall be verified by review of appropriate documentation of required inspections, etc.,
before any lift in a CLZ greater than 2,000 pounds.
3.1 The reactor building polar crane must meet the requirements given in Reference 2.2.
The reactor building polar crane (35-and a
175-ton hooks) is the only handling device approved for lifts I-greater than 2,000 pounds inside primary containment in any active critical lifting zone.-
E..
The auxiliary building crane must meet the requirements given in 3.2 Reference 2.2.
The auxiliary building crane (10- and 125-ton hooks) is the only handling device approved for lifts greater than 2,000 pounds.inanyactiveCLZintheauxiliarybuilding(El.734).

?
3.3 The sling (s)~or special lifting device (s) to be used fbr' lifting in the CLZ's must satisfy the requirements given in Reference 2.2.

Standard Practice Page 2 SQM-56 7/21/81 3.4 The reactor building and auxiliary building cranc operators must meet the training and qualification requirements given in Reference 2.2.
~
The crane flapan must be trained in accordance with the signals 3.5 provided in Reference 2.2.
4.0 PRECAUTIONS 4.1 Maintain' a minimum' clearance between the load and the floor or object over which the load must pass.
4.2 Clearance over the steam generators from the #1 and #2 RCP area will not be sufficient in some control lifts. These lifts can I
only be performed over an open reactor head when shield head blocks are in place.
5.0 ALARA CONSIDERATIONS 5.1 Work closely with Health Physics to identify lifts which require special consideration to minimize personnel exposu're.
6.0 WORK INSTRUCTIONS 6.1 Verify that the lift to be made is an approved' lift by locating the
~
appropriate entry in Tables 1, 2, and 3.
Note the referenced pro-cedures and safe load path specified on Attachments A, B, and C.
6.2 Complete the prelift requirements on Data Sheet A.
6.3 Raise and transfer the load to its destination, following the safe I'
path given. A " standard" safe load path is the most direct path into and out of the critical zone which minimizes time and proxi-mity to the open vessel or fuel in racks.
~
6.4 Indicate satisfactory completion of the lift in a safe manner con-sistent with the given precautions, restrictions, and safe load path by initalling the appropriate column on Data Sheet A.
6.5 If this instruction is performed in conjunction with another ap-proved instruction (i.e., MI-1.2), submit the completed Data Sheet I'
A at the completion of that instruction as part of the data package.
Otherwise, the completed data sheet must be submitted no more than one week after completion of the lift.
NOTE: Several unrelated lifts may be documented on a single Data ^ '
Sheet A.
