  1. SA12-PE-04Feedwater System Multidiscipline Review (Deep Dive) January 24, 2013

  2. SA12-PE-04 Purpose and Scope • The purpose of this self assessment is to conduct a multi-discipline team review (deep dive) of the Feedwater System following Recommendation #8 from INPO IER Level 2 11-2, 2009-2010 Scram Analysis . This evaluation will be performed to validate the effectiveness of station processes to identify, track, and resolve off-normal or low margin conditions in the Feedwater System using the attributes listed below.

  3. INPO Event Report, Level 2, 2009-2010 Scram AnalysisRecommendation #8 • Conduct a multidiscipline team review (deep dive) of at least two systems or components that have been identified as significant contributors to plant scrams in this scram analysis or by station-specific analyses. Attachment 5, Technical Data Analysis, provides a list of scram-significant systems for each NSSS type to assist in determining scram-risk-significant systems. These evaluations will be performed to validate the effectiveness of station processes to identify, track, and resolve off-normal or low margin conditions.

  4. SA12-PE-04 Team • Host Manager: Kirk Weir • Team Leader: Tod Welsh • Team Members: • James Alston, STP FW System Engineer, External Peer • John Waters, Engineering Specialist III, PSE

  5. Performance Objective 1 • Determine whether or not the Feedwater system is or is not being operated as designed. Include current configurations, operator workarounds and burdens, disabled annunciators/alarms, and controls being operated in manual (vs. automatic).

  6. Performance Objective 2 • Determine if deficiencies exist in the Feedwater equipment, to include corrective and deficient critical and noncritical backlogs, which lower system reliability.

  7. Performance Objective 3 • Verify relevant internal and industry OE and vendor recommendations are reviewed for applicability for the FW system.

  8. Performance Objective 4 • Verify FW design changes applicable to off-normal or low margin conditions are addressed.

  9. Performance Objective 5 • Verify preventive maintenance work not excessively deferred for FW.

  10. Performance Objective 6 • Verify previous corrective actions to resolve Feedwater system and component vulnerabilities to scrams and transients have been effective.

  11. Performance Objective 7 • Verify that identified Feedwater issues are appropriately captured in system and component health reports and in the corrective action program
