2014 Summary • Two AFIs; Four Performance Deficiencies
– Two – underground piping – Four – cathodic protection
• Improvement needed – Degraded coatings and cathodic protection not
properly maintained – Cathodic protection equipment work
prioritization and completion – Cathodic protection site knowledge weaknesses – Leaks occurring and the source is not
determined

Good Underground Piping Program Attributes
• ICES reporting quality improvement • Zero leak tolerance – especially in piping
containing radioactive fluids • Cathodic protection installed and maintained • Failure causes identified • Effective station and corporate oversight • Effective use of corrective action program
