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
