Plant Types of degradation Response

CS

Austenitic (TP304)welds were found IGSCC in recirculation piping system.

Replace 10 riser pipes (SS TP316)

Austenitic (TP304)welds were found IGSCC in non-replaced recirculation piping system after 2nd interval.

Weld Overlaid

Condenser Cu-Ni tube with corrosion Replace all tubes w/Ti

KS

Austenitic (TP304)welds were found IGSCC in recirculation piping system.

Weld Overlaid

Condenser Cu-Ni tube with corrosion Plugged & Replace some tubes

MS AVB Wear, scale blockage, loose parts wear, tube end SCC in SG Plugged, Chemical cleaning

Business Need• Need for migration to PC software

• Old legacy HPUX hardware• Obsolete systems not supporting new inspection products and technologies

• Increase in Productivity• Reduction in process costs• Compatibility with other PC products

8

• Needs in selection process• Widely accepted and commercially available software

• Familiarity for existing operators• Presenting best technologies• Validation of transition

Migration Plan

Migration Plan

• Replace Eddynet CDS with RevospECT• Incorporate RevospECT Basic• Customized version of RevospECT PRO• Tuned to specific requirements and specification• Effective Transition Plan

10

Implementation Plan

• Eddynet AQ/AN/DM Implementation• Full PC Based Networked System Integration

• Retired aging HPUX Hardware

• Phased in over several Years• AQ & DM (2013)• AN & DQV (2014)• RevospECT Basic – Current Configuration (2015)

13

• RevospECT Commercial Software• Basic Vs. Pro Version

• Customized for Customer Needs• Noise Measurement not required• Final Acceptance logic not implemented• HDC (Historic Data Compare) not included

Implementation Plan

14

• RevospECT Basic• Replicated Previous CDS Parameters• Simple User Adjustable Parameters• Increased User Capabilities over CDS

• Productivity – Multiple Cal Groups Simultaneously• Landmarking improvements• Regions Of Interest – no missed overlap• Enhanced Calibration/Validation• Expanded Analyzer Methodology• Simultaneous Reporting of Results (flaws, sludge, dent)

Implementation Plan

Taiwan Power Quote• “With the implementation of Zetec PC products and RevospECT Basic, Taiwan Power was able to smoothly transition from legacy Unix products to state‐of‐the‐art PC products and technology. Realizing this new potential, this technology was also applied to our RCCA and Condenser inspections with great success. We will look for other opportunities to apply Zetec advanced technology.”
