For short-lived components an expert panel approach was taken to optimising the preventive maintenance programme, see Figure 12. Current maintenance task lists were compared against external best practice and gaps identified.

111.2.2. LCM ANNUAL REVIEW

At most of the multi-unit CANDU NPPs, the life cycle plans and condition assessments for all critical equipment in the safe operating envelope (SOE) systems are reviewed annually. Input from system health reports and system health monitoring plans (SHMP), as shown in Figure 1, ensures that the condition assessments remain current.
