.- , Enclosure 1 JWC to HRD Serial 22008 HEAVY LOAD HAhTLING DEVICE DESIGN INFORMATION

1. The heavy load TER requested more information on the design of some of the handling systems capable of lifting heavy loads (greater than 1700 lbs).

These systems are:

a. Filter Plug Hoist

b. Portable Crane

c. Rigging Beam - Snubbers

d. Rigging Beam - Reactor Vessel Head Studs

e. Rigging Beam - Miscellaneous Equipment (Unit 2 Containment)

f. Rigging Beam - Letdown Coolers

g. Rigging Beam - Shield Plugs The filter plug hoist has a 1 ton capacity and is used to lift a shield plug weighing 1050 lbs. The plug is not a heavy load and therefore not a NUREG-0612 concern. The hoist is designed to the requirements of ANSI B30.16-1973.

The portable crane listed in Table 4 of the Midland Part I heavy load response does not exist.

The snubber rigging beams are installed in Unit 1 containment and the plans to install them in Unit 2 containment have been changed. They have not and will not be used.

The remainder of the handling devices listed above are designed to withstand the loads and forces imposed as specified in ANSI B.30.2-1976, Section 2.1.3.2.a.1. The materials used conform to the requirements of CMAA Specification 70-1975, Section 3.1. The general construction of the rigging beams is also in conformance with the applicable portions of Section 11-1.3 of ANSI B30.11-1980 and Section 1.3 of the AISC Manual of Steel Construction, Seventh Edition.
