Licensee Event Report No. 98-010-00 and
10CFR, Part 21 Report No. 21-97-060
Dear Madam or Sir:
Enclosed is Licensee Event Report (LER) No. 98-010-00 and 10CFR,
Part 21 Report No. 21-97-060: Inoperable Divisions 1 and 2 Hydrogen and
Oxygen Analyzers Due To Inadequate Commercial Grade Dedication of Safety-
Related Replacement Parts By Supplier. This report is being submitted in
accordance with the requirements of 10CFR50.73 and 10 CFR, Part 21.
The enclosed report contains the following commitments:
o Indeterminate safety-related material supplied by Sentry
Equipment Corporation and installed in the Hydrogen and Oxygen
Analyzers will be evaluated and any unqualified material will
be replaced or qualified.
o Safety-related material in warehouse inventory supplied by
Sentry after June 1992 was placed on hold. This material will
be evaluated under the Illinois Power (IP) commercial grade
dedication program prior to installation.

o To prevent the future receipt of inadequately dedicated
material from Sentry, one of the following restrictions will be
added to the Qualified Supplier List (QSL) for Sentry Equipment
Corporation: a requirement for Sentry to submit commercial
grade dedication plans to IP for review and approval prior to
Sentry purchasing and/or manufacturing safety-related parts; or
a requirement for a 100 percent source surveillance on all
procurements from Sentry; or Sentry will be removed from the
QSL, whereby IP would procure material as commercial grade
items and dedicate them for safety-related application.
o The process used to qualify suppliers of safety-related
material for use at CPS will be reviewed. The review will
emphasize improvements that could minimize the potential for
recurrence of a similar event.
Sincerely yours,
Walter G. MacFarland, IV
Senior Vice President and
Chief Nuclear Officer
