LICENSEE:
Florida Power and Light Company (FPL) i FACILITY: Turkey Point, Unit 3
SUBJECT:
SUPMARY OF MEETING HELD ON OCTOBER 2,1978 TO DISCUSS 4
AN EXTENSION OF THE OPERATING INTERVAL FOR FOUR MORE MONTHS q
Background
i Turkey Point 3 was granted an extension of two equivalent months to the operating interval of six equivalent months from February 1,1978 1
by Amendment 36 on June 2, 1978. The purpose was to avoid having Unit 3 shutdown for a steam generator inspection at the same time Unit 4 was shutdown for reload and steam generator inspection.
On July 19, 1978 a small leak was detected in steam generator 3c.
The leak was plugged the first week in August.
On September 26, 1978, I
l Florida Power and Light Co. (FPL) submitted a proposed amendment request which would extend the operating interval for Unit 3 an additional four equivalent months.
In addition to a technical basis, dollar and man-rem costs were cited. This meeting was called to discuss the amendment request in more detail.
See Attachment 1 aj for a list of attendees.
1 Meeting Sumary O
Mr. George Liebler presented the following impact related information:
1.
An estimated 200 man-rem of exposure can be expected to I
result from a shutdown and full steam generator inspection.
(
1 2.
Six to seven million dollars would be expended by FPL for l
replacement power costs.
3.
And the loss of economic benefit due to an inspection shut-down would last for approximately 21 days.
4.
The last tube leak report was in August 1978.
I I
5.
A small detectable but non-changing leak now exists.
l l
l 6.
If the requested extension is granted, the Unit 3 full steam i
l generator inspection would be accomplished at the next refueling i
outage, expected to occur on January 1979.
I
- . r Florida Power and Light Company,
4 A technical basis in support of the requested extension was presented a
by the Westinghouse personnel.
This was an elaboration of the data i
presented in the September 26, 1978 proposed amendment request.
The techniques of. the analyses performed were reviewed with an explanation of the conservatism employed.
We indicated that we would need additional supporting bases to complete our review of FPL!s request for extension.
k The bases should include assurances that, should substantial leakage
'}
resulting in shutdown occur during the extension period requested, positive corrective steps will be taken on tubes that exceed the tube
([)
plugging criteria.
Also, there should be assurances at this time that a full inspection of all three steam generators will be performed j
in the event that the extent of tube degradation is found to exceed the presently projected low rate of degradation.
The licensee agreed to respond to these areas of concern as soon as possible.
We stated that with a timely FPL response, we would expect to make a licensing decision prior to October 17, 1978, the time Unit 3 will otherwise be required to shutdown if the requested extension is not granted.
