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 hold meetings and report on activities at STG 41 and at TEG 465X future
TG 404 5

TG 404 –Nuclear Buried Piping

 To produce a report on the corrosion “and protection” of 

buried pipes in nuclear power plants. This report will focus on 

evaluating corrosion management systems designed to protect 

buried pipes within nuclear power plant facilities from external 

corrosion. 

TEG 465X–Nuclear Buried and Underground Piping

 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.

Task Groups
TG 404 6

TG 467–Materials Selection for Buried Piping in the 

Nuclear Industry

 To write a standard material requirements (MR) for materials 

selection for nuclear buried piping.

TG 471–Nondestructive Evaluation (NDE) Technologies to 

Evaluate Buried Pipe on Nuclear Sites

 To write a standard on nondestructive evaluation (NDE) 

technologies to evaluate buried pipe at nuclear generation 

sites.

New Task Groups
TG 404 7

TEG 473X–Power Generation and Delivery Education 

Roadmap 

 To identify and qualify industry needs for training and 

certification of engineering, maintenance and construction 

personnel in system design, mitigation of degradation 

mechanisms and remediation of preexisting component 

degradation

TG 491–External Cathodic Protection for Nuclear Power 

Plant Piping Systems.

 To write a standard practice that defines design, construction, 

maintenance, and operation of cathodic protection systems in 

nuclear power plants.

New Task Groups (continued)
TG 404 8

TG 481–Nuclear Power Plant Buried Pipe Coatings 

Condition Assessment

 To develop a standard practice for characterization of buried 

pipe coating condition during direct (bellhole) examination.

TG 485–Identification of Existing Buried Pipe Coatings in 

Nuclear Power Plants.

 To develop a standard practice for determining the type of an 

existing buried pipe coating system.

New Task Groups (continued)
TG 404 9

 Corrosion Technology Week, September 22-26, 2013, Vancouver, 

Canada

 Symposium Corrosion 2014

Title: Corrosion and Corrosion Control of Buried Piping in Nuclear 

Power Plants”. 

This symposium is seeking technical papers...On complex congested 

buried and underground piping systems in Nuclear Power Plants 

addressing coating, cathodic protection, and non-destructive examination 

issues considering copper grounding, bimetallic contacts, material 

selection, acceptance criteria. The deadline for doing so is MAY 1, 2013.
