Gentlemen:

SUBJECT:

INSPECTION REPORT NOS. 50-269/86-11

This refers to the Nuclear Regulatory Commission (NRC)

inspection conducted by

N. E. Economos on March 20 -

21,

1986.

The inspection included a review of

activities authorized for your Oconee facility.

At the conclusion of the

inspection, the findings were discussed with those members of your staff identi

fied in the enclosed inspection report.

Areas examined during the inspection are identified in the report. Within these

areas,

the inspection consisted of selective examinations of procedures and

representative records, interviews with personnel, and observation of activities

in progress.

Within the scope of the inspection, no violations or deviations were identified.

On May 2, 1986,

NRR issued a Safety Evaluation Report entitled Oconee Unit 1,

Duke Power Company,

Safety Evaluation of the Ultrasonic Flaw Indication Detected

in the Reactor Pressure Vessel.

Your attention is directed to the provisions

delineated in the conclusion of the SER which requires that the following infdr

mation be submitted before June 16, 1986.

1.

Submit the additional information requested by the staff during the

April 21, 1986 meeting and contained in the summary section of this report.

2.

Submit a technical report summarizing your on-going ultrasonic testing

program on the vessel mockup at the Mt. Vernon facility.

In addition, the staff considers several ultrasonic reflectors, which are pre

sumed to be flaw indications, to be conditionally acceptable in accordance with

Subparagraph IWB-3122.4 of Section XI of the ASME Code and, therefore, requires

augmented inservice inspections based on 10 CFR 50.55a(g)(4).

Also the staff

requires that the best available techniques and instrumentation be used during

the next scheduled refueling outage inspection to evaluate these indications.

The staff requires that you provide a report at least six months before the next

scheduled refueling outage describing detailed plans for this inspection.
