Mechanical Seal Failure Report LER 89-008 by Saeed Ahmed is a document available to read on EtoBox.

- At a nuclear power plant, a low pressure safety injection pump was removed from service for maintenance. During testing after maintenance, excessive seal leakage was found, requiring seal replacement. - Since seal replacement would take longer than allowed by technical specifications, the plant initiated an orderly shutdown. The reactor safely reached minimum power conditions within the required timeframes. - The seal failure was determined to be caused by oil contamination introduced during maintenance.
