Mr. A. C. Thies, Vice President Production and Operation Power Building h22 South Church Street Charlotte, North Carolina 20201 Gentlemen:
This letter relates to the discussion Messrs. C. E. Murphy and C. M. Upright of this office held with Messrs. J. E. Smith, J. W. Hampton, J. C. Rogers, D. H. Beam, and G. L. Hunnicutt of your staff at the conclusion of the inspection conducted on February 2h through 26, 1971, regarding the construc-tion activities authorized by AEC Construction Permit No. CPPR-33.
As noted during the discussion, an item was identified which apparently was not in conformance with statements in the Final Safety Analysis Report and your cleaning procedure as identified below, or which may otherwise raise questions concerning the adequacy of the construction. This item is as follows:
The Final Safety Analysis Report, Sections 4.h.2 and 13.51, specifies the cleaning requirements and procedures for the reactor coolant piping and equipment.
Section h.h.2 requires the reactor coolant piping and equipment to be cleaned both before and after erection. Section 13.5.1 r* quires that detailed written procedures be provided to verify that all quality control requirements for Oconee are met.
The Peactor Coolant System Cleaning Procedure, TP 200 16, states in part, ".
. all necessary precautions shall be taken to prevent contaminants from entering the clean area with the personnel. Examples of contaminants are oil, metal chips, wire, scale, savdust, grease,
sand, organic materials, chemicals, paint, and any other foreign materials."

Contrary to these requirements, the clean area established in the i
reactor vessel after cleaning was not properly protected or ade-quately inspected to prevent the vessel internals from being recon-taminated by vood splinters from the access ladder rungs. In addition, a strip of polyethylene was trapped between the :nating flanges of the core support shield and the core barrel and was not removed.
Pleaso provide us, within 30 days, with your co ents concerning this item and any steps which have been or vill be taken to correct it and to mini-nize recurrence including any appropriate changes that have been or vill be made to your quality assurance program.
Should you have any questions concerning this =atter, you may conmunicate directly with this office.
