REGIONAL ACT10:4 Catawba 1 & 2 Licensee 9/9 CDR - ljnsuitable Rubber Application to Diesel Followup per DNS:50-413 Gjgterator Coupling - Per the 6/23 letter from MC 2512. 414 DeLaval Co. to NRC reporting a Part 21 item, Region IV Notified.
Catawba was listed as one of the plants that Cat I received an unacceptable governor drive coupling manufactured by Koppers Co., Inc.,
Baltinore, MD.
The cancern is that Isoprene rubber material was used in the coupling.
This rubber tends to deteriorateg under oil and high temperature conditions which creates the potential of metal to metal contact between flanges in the coupler while the diesel generator is running.
Metal to metal contact can give false indication of generator frequency and trip out the running DG.
For corrective action the licensee will remove couplers having Isoprene material and replace w.n c.pty> rpan then whicr wou d have m.20prene material, liritten report due 10/ 8.
