DEC 7 1931 Docket Hos: 50-369 and 50-370 i
LICENSEE:
DUKE POWER COMPANY j
FACILITY:
McGuire Huclear Station, Units 1 and 2
SUBJECT:
SUMMRY OF HEETING HELD ON NOVEMBER 20, 1981 i
j A meeting was held with the licensee on Noverber 20, 1981, to discuss preheater-
]
type stean generator tube problems in foreign reactors as ralated to the operation of McGuire Unit No.1.
A list of attendees is shown on Enclosure 1.
The major briefing presentation was nade by Westinghouse and included the results to date of testing of the Model D steam generator at two foreign reactors. These steam generators are of sinilar design (Model D) to those in the McGuire Unit 1 pl a nt.
Eddy Current testing has revealed that there are indications in the outer rows of tubes in essentially all steam generators so tested. Westinghouse has l
initiated a program of testing and tube examination along with analytical evalu-ations to determine the initiator of this tube degradation phenomena. Westinghouse believes at this time that tube degradation can be attributed to excitation of the tubes from high fluid velocities and/or non-uniforn velocity distribution.
I The licensee stated that McGuire Unit I was shut &.n on November 16, 1981 and that j
an operating plan for Unit 1 had been developed (see Enclosure 2). Rows 47, 48 and 49 in "A" Steam Generator (S/G) were Eddy Current tested. The results were negative J
with possibly one sif ht indication. The licensee has installed external vibration 9
nonitors (3 transducers per S/G) on each S/G. Upon completion of this inspection effort, the unit will be restarted and a power level of 75% established, approx.
Hovember 23. Upon completion of the traditional 75% plateau power ascension testing
( 2 weeks), the unit will be shutdown and S/G Eddy Current testing repeated on S/G "A".
During unit operation, nonitor instrumentation will be evaluated.
Interim operation on the above basis appears appropriate at this time.
t The licensee indicated that further operation at 90% power is contenplated to con-plete some ascension testing ( 1 week) provided no indications above 20% are dis-4 i
covered in S/G "A".
Following this week of testing, evaluation of the monitoring, and evaluation of 50-90% power data, they wculd decide on escalation to 100% power for one day. Data evaluaticn at this time would determine whether or not the licensee would plan to continue operation at an acceptable power level or shut down at that tine for further EC testing.
