Description

The Maintenance Rule Monitoring System aides in implementing the requirements for the task of 10CFR 50.65, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants". It helps to ensure that safety-related systems, structures, and components (SSCs) are capable of performing their Maintenance Rule functions.

The Maintenance Rule Monitoring System allows the Maintenance Rule Coordinator to maintain the overall implementation and oversight of the maintenance rule program. Documentation is kept up to date within the application. The Application assists in the Data collection for availability, reliability, and condition monitoring is automated.

Unavailability Tracking

Key features pic
  • Set the allowed unavailability hours in a system at the Train or Subsystem level.
  • Monitor unavailability and availability over a 3-year rolling window for past and future
  • Unavailability is tracked against Plant Mode Changes.
  • Unavailability is tracked at the train level, and it rolls up to the System as a sum or average.
  • Can be configured to predict unavailability in the future based on scheduled work.

Functional Failure Tracking

  • Identify Repetitive Maintenance Preventable Functional Failures
  • Functions approaching their Failure limit are highlighted with a different color in the navigation screen.
  • Associate components with Maintenance Rule Functions to help determine the causes of recur-
