MAJOR PLANT CRANE REVIEW Notes 1.

Impact allowances used in calculation are as follows. Designs were found to be acceptable based on these values:

Polar Crane

- 15% of rated capacity Turbine Bldg. Main Crane - 15% of rated capacity Turbine Bldg. Aux. Crane - 15% of rated capacity Intake Structure Crane

- 15% of rated capacity Spent Fuel Crane

- 15% of rated capacity 2.

Polar Crane short stiffener bearing stress exceeds CMAA requirement of 26.4 ksi. Further analysis indicates that this will not impair overall crane performance i.e., box girder is not adversely affected.

3.

In all cranes, longitudinal stiffeners are placed lower than CMAA requires.

In addition, the moment of inertia of these stiffners does not meet CMAA requirements in three cases. This reduces the allowable web plate compressive stress. Calculations indicate that stress values are within the limits of the reduced allowables. In addition, the ef fectiveness of the longitudinal stif feners is judged to be acceptable for continued operation.

4.

Drawing review indicates latches supplied on all hooks.

5.

Calculations indicate rope safety factors meet CMAA requirement.

6.

Insufficient data available on drawings to allow evaluation of this item. Vendor data not obtained -' reference Conference Notes 769.

7.

Calculations indicate all cranes meet CMAA.

8.

All cranes furnished by Whiting Corporation.

9.

This review was based solely on purchase documents, approved drawings, and various correspondence. Equipment condition was assumed to be as originally furnished. No physical inspections were performed to further verify existing conditions.

Review of Special Lifting Devices Against ANS1 N14.6 Notes:

1.

Evalustions were based on latest design drawings and original equipment condition.

2.

Under comments heading the following symbols are used:

  • S = Heets ANSI N14.6 Section 5.3.2.1.1 N = Does not meet ANSI N14.6 as underlined, but, satisfactory for continued use N/A = ANSI N14.6 Not applicable 3.

The following dynamic load factors are included in the tabulated results:

A.

Closure Head Lift Rig

- 0.5 B.

Upper Guide Structure Lift Rig - 0.3 C.

ICl Plate Hoist Assembly

- 0.3 D.

Filter Cask Lift Rig

- 0.3 E.

Seal Ring Lift Rig

- 0.3 F.

Core Support Barrel Lift Rig

- 0.3 4.

Stress design factor required is a minimum of 3 for yield and 5 for ultimate.

Evaluation criteria for all devices is based on normal design as the crane design is not based on single-failure-proof criteria.
