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. U-602977 Page 2 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.
