SUBJECT:

NRC REGION I INSPECTION

REPORT 50-244/95-11

Dear Dr. Mecredy:

This letter transmits

the findings of the announced

safety inspection

conducted

by Mr. Prakash

Patnaik of this office from May 1-3,

1995, at Ginna

Nuclear

Power Station, Ontario,

New York.

The inspection

was directed at areas

important to public health

and safety,

through reviews of the inservice inspection

program,

and the steam generator

eddy current examination

program during the spring

1995 outage of the unit.

The inspector also assessed

your evaluation of deficient conditions in some of

the steam generator

upper sleeve

welds found during eddy current examination

of sleeved

steam generator

tubes.

The inservice inspection

program

and the eddy current examination

program for

Ginna were found to be comprehensive

and in some instances

exceeded

the

requirements

of the applicable

ASME code,

Section

XI and the technical

specifications.

Your evaluation of the root cause

leading to defective sleeve

welds in the steam generator

is considered

to be acceptable,

based

on

inspector's

review of the pertinent records

and interviews with personnel.

The incomplete tube sleeve

weld and subsequent

failure of the ultrasonic

examination violate

a number of criteria, including Ginna

UFSAR paragraph

5.4.2.7.2,

(Rev.

10,

12/93)

and

10 CFR Part 50, Appendix

B Criteria IX,

"Control of Special

Processes."

Because

Rochester

Gas

and Electric identified

the incomplete weld, it could not be reasonably

expected

to have

been

prevented

by Ginna corrective action for a previous violation (because

there

weren't any); it was corrected

in a reasonable

time;

and it was not willful;

(10 CFR Part 2, Appendix C, B(2)) this is

a Noncited Level

IV Violation.

In accordance

with 10 CFR 2.790 of the

NRC's "Rules of Practice,"

a copy of

this letter

and its enclosures will be placed in the

NRC Public Document

Room.
