SUBJECT:
Suf!!ARY OF ttARCH 23, 1982, CONCRETE FILL DESIGN TO MITICATE HYDRODYNAMIC LOADS ON CONTAINMENT INTERNAL EQUIPMENT PIPE SUPPORTS repres ntatives of the Gulf States Utilities Company On March 23, 1982, e
and their consultants met with raembers of the NRC staff to present information on a proposed concrete fill design to mitigate hydrodynamic loads on the containment internal equipment pipe supports. A list of attendees is provided as attachment 1.
A copy of the GSU presentation is provided as attachment 2.
Following the presentation, concerns were raised by the NRC staff in accounting for tangential loads at the shield building / concrete fill interface and the use of the maxi-bolts in an application which was not previously addressed to the staff and the factor of safety to be applied in their use. The staff will evaluate this proposal after it is formally submitted by the applicant. This proposal will be addressed in a future amendment to the FSAR.
