This would be a review of all engineering design and operational documents, past test data including regular scans with on-line test methods. New oil tests would be undertaken. This should identify the common problems and prioritize which offline tests are more important in second phase for detail review Activities: External inspection, IR/UHF surveys, and oil tests for main tank and LTC including DGA and FURAN,
Focus on those that indicate risk from Sage 1. Undertake a range of outage tests to investigate issues, and correlate with assessment from stage 1. Activities: Off line tests- PF/Cap, Winding and insulation resistance, SFRA, Turns Ratio , Leakage Reactance,
