August 23, 1993 Docket No. 50-382 Mr. Ross P. Barkhurst Vice President Operations Entergy Operations, Inc.
Post Office Box B Killona, Louisiana 70066
Dear Mr. Barkhurst:
SUBJECT:
REVISED BORAFLEX SURVEILLANCE PROGRAM OF THE SPENT FUEL POOL RACKS WATERFORD STEAM ELECTRIC STATION, UNIT 3 (TAC NO. M86006)
By letter dated December 31, 1992, the staff of Entergy, Ir.c. (the current licensee, formerly Louisiana Power and Light (LPL]), submitted a revised surveillance program for monitoring the Boraflex panels contained in the spent fuel racks at the Waterford Steam Electric Station, Unit No. 3 (Waterford 3).
It had been determined earlier that use of coupons might not be adequate to monitor the extent of gamma radiation induced gaps in spent fuel pool Boraflex panels. Consequently, in December 1987, LP&L proposed an alternative surveillance program for the Boralflex panels in lieu of the previous Boraflex coupon surveillance program.
The new surveillance program, as documented in Section D of the attachment to the December 31, 1992, letter, includes the following steps:
Gamma exposure tracking of the spent fuel pool Boraflex panels.
Periodic nondestructive testing, at a maximum 4-year interval time, of selected Boraflex panels. The testing uses neutron attenuation (blackness testing) as a means of detecting gaps -
(discontinuities) along the Boraflex panels. The licensee's nondestructive testing data of selected Boralflex panels in November 1992 will be used to provide a baseline for the trending of gap formation in the panels.
Sixteen spent fuel pool exposure cells with freshly discharged fuel in them to serve as samples for trending the effects of high gamma radiation exposure on Boraflex panels.
These 16 exposure cells will be tested as described above and are expected to lead the spent fuel storage racks in gap formation.
Periodic destructive testing on selected panels if engineering assessment determines it is necessary.
Monitoring and comparisons to industry developments to determine the latest methods for testing and monitoring Boraflex performance.

h Mr. Ross P. Barkhurst,
We have reviewed the alternative Boralflex surveillance program and find that the program provides an acceptable means of monitoring the integrity of the Boraflex panels used in the construction of the Waterford 3 spent fuel pool storage racks.
The baseline surveillance results in the submittal indicate that the Boraflex panels in the spent fuel pool storage racks are currently capable of performing their intended safety function.
The Entergy submittal of December 31, 1992, indicates that you have met your
)
prior commitments to (1) terminate the Boraflex coupon surveillance program, (2) establish and maintain a database of the calculated Boraflex panel gamma exposures in the spent fuel storage racks, (3) submit nondestructive test results on several Boraflex panels, and (4) establish a surveillance program as discussed above.
We agree that you have completed the first three commitments and that you will continue to have a surveillance program as necessary to meet the stated objectives.
i If you have any questions on this matter, please let me know. This completes the action under TAC No M86006.
Sincerely, ORIGINAL SIGNED BY:

The Entergy submittal of December 31, 1992, indicates that you have met your prior commitments to (1) terminate the Boraflex coupon surveillance piogram, (2) establish and maintain a database of the calculated Boraflex panel gamma exposures in the spent fuel storage racks, (3) submit nondestructive test j
results on several Boraflex panels, and (4) establish a surveillance program 4
as discussed above. We agree that you have completed the first three commitments and that you will continue to have a surveillance program as necessary to meet the stated objectives.
If you have any questions on this matter, please let me know.
This completes 1
the action under TAC No. M86006.
