Master Power Connecting Rod
Dear Sir:
Cooper Bessemer Reciprocating Products Division has previously reported a
potential problem with the master power connecting rods utilized in
Cooper Bessemer "KSV" Emergency Diesel Generators in letter to the NRC.
These reports are identified as QCG-3364 dated January 12, 1987 and QCG-
9995 dated November 9, 1994.
The purpose of this letter is to provide information as to ongoing
activities. A review of-house records was conducted along with
representatives from Commonwealth Edison Company (CECO) and Arizona
Public Service in January 1995.
Four master connecting rods 7C0901, 7C0903, 7C0904, and 7C0905 were
identified in a letter to CECO on January 30, 1987, our reference QCG-
3419, as having some iron plating on the bail of the master connecting
rod. Although there was not a structural concern at that time, the
recommendation was to return the four master connecting rods to Cooper
for further inspection.
In April 1989, the four master connecting rods were returned to Cooper
from CECO and inspection with ammonium persulfate confirmed that iron
plating was present on the one side of the bails but not in the
articulated art rod bore. These four rods were evaluated at that time
(1989) as suitable for use by Cooper's Material Review Board and
subsequently returned to CECO in April 1990. These four rods were
reassembled in an EDG at CECO, Zion.
With the failure at CECO, Braidwood on November 3, 1994, and subsequent
discovery in January 1995 that these four master connecting rods were
returned in 1989 with iron plating still present, CECO, Zion Station has
removed these master connecting rods from their EDG. Cooper acknowledges
this action, and upon subsequent reinspection to determine the validity
of the 1989 Material Review Board evaluation, will issue a final report
on this matter.
