 Discussed extensively at the meeting held March 13 during Corrosion 2012.

 Disposition of TG members’ comments completed 

 Report undergoing “internal” review (i.e., within selected members of TG 404)

 “Final” comments to be reviewed before forwarding to NACE HQs

 NACE HQs will format report and send out for ballot

 Dates TBD

Status of Report
TG 404 8

 Release of report “completes” the scope of TG 404

 New Task Groups (TGs) and Technology Exchange Group 

(TEG) will carry-forward the gaps itemized in the report

 Chairs have signed up to actualize the requirements

Subsequent Work
TG 404 9

NEW TEG

 Name: TEG 465X “Nuclear Buried and Underground Piping”

 Task: To liaise between the sponsoring committees and the specific task 

groups which will develop standards, training, inspection, and assessment 

of buried/underground piping in nuclear power plants while focusing on 

discussions for the application of cathodic protection and coating systems.

 Chair: Gabriel Ogundele (Kinectrics Inc.)

 Vice-Chair: Hank Kleinfelder (Mears Group)

 Administering STG: STG 41

 Sponsoring STGs: STG 03, STG 05, and STG 35
TG 404 10

Path Forward

 Develop Standard for Cathodic Protection for Buried Piping in 

Nuclear Power Plants

 Develop Standard for Coatings for Buried Piping in Nuclear Power 

 Develop Standard for Materials Selection for Buried Piping in 

Nuclear Power Plants

 Develop Standard for NDE of Buried Piping in Nuclear Power Plants

 Review Training for Nuclear Buried Piping

All new TGs will report at the Corrosion Technology Week 2012 with first draft
