This meeting was a follow-up of previous meetings between NRC and TVA held on Decembr 18, 1989 (Meeting SuIIIIary dated December 22, 1989),

and January 18,,

1990 (Meeting Summary dated January 29, 1990).

At the meeting, TVA presented a revised test program incorporating the staff comments resulting from the January 18, 1990 meeting.

TVA provided a review of the ranking procedure by which conduits are selected for-testing and a

review of the confirmatory test program.

TVA stated that the conduit walkdown will note the actual conduit installation details and these details will be reflected in the calculation of the sidewall bearing pressure.

The staff concurred, with the test program proposed in Enclosure 2, subject to the following conditions:

1.

TVA will obtain NRC approval for any test which cannot be conducted on a flooded conduit.

NRC will reserve the right to substitute or require additional conduits to be tested if a wet test cannot be conducted on all conduits in the initial sample.
