2 - Section 2.3.2 - Procedures Duke will include the requirements for safe load paths in both new and existing procedures pertaining to heavy load lifts.
'3 - Section 2.3.3 - Crane Operator Training Duke will maintain suitable records of crane operator training.

A subsequent report will be provided by August 15, 1983.
5 - Section 2.3.5 - Lifting Devices (Not Specially Designed)
Cranes and hoists purchased for use at the Catawba Nuclear Station have maximum full load speeds of the hoist of 20 feet per minute.
6 - Section 2.3.6 - Cranes (Inspection, Testing, and Maintenance)
Duke will comply with the requirements of ANSI B30.2, Chapter 2-2 pertaining to inspection, testing, and maintenance requirements. Records will be developed to show that each crane or hoist is in compliance.

Mr. Harold-R. Denton, Director
-June 28, 1983-Page 2 7 - Section 2.3.7 - Crane Design A comparison of.the Westinghouse Specification for the manipulator cranes with CMAA-70 and ANSI.B30.2 reveals that these devices meet both specifica-tions with the following exception:
Welding is.'done in conformance with ASW D14.1 " Specification for Welding ' Industrial and Mill Cranes and not AWS D2.0-66 " Specification for Welded Highway and Railway Bridges" as required by ANSI B30.2.
We are still investigating the Codes and Standards that apply to R0ll and R012. _Since these cranes are designed in accordance with EOCI-61, further study will be necessary to compare'this with CMAA-70. A followup response will be provided by August 15, 1983.
Very truly yours,.
