ASME Section XI
• Division 1: Rules for Inspection and
Testing of Components of LightWater-Cooled Plants (2010 Edition
with the 2011 Addenda)
• Division 2: Rules for Inspection and
Testing of Components of Gas-Cooled
Plants (1992 Edition with the 1993
Addenda)
• Division 3: Rules for Inspection and
Testing of Components of LiquidMetal-Cooled Plants (2001 Edition
with the 2002 Addenda)
 Change
of publication cycle
 No longer on a three year Edition cycle with yearly Addenda
 Two year Edition cycle, 2013, 2015, 2017, etc.
 Code Cases published four times per year
 Documents that clarify the intent of existing Code requirements or provide
alternative requirements
 Interpretations will be posted online
 Formal written responses to written inquiries
 New

Working Groups and Task Groups
Working Group Non-Metals Repair/Replacement Activities
Task Group on Repair by Carbon Fiber Composites
Task Group on HDPE repair/replacement
Task Group Buried Components Inspection and Testing
Task Group on High Strength Nickel Alloys Issues
 Regulatory
◦ Separation of regulatory requirements
 Numerous places where Section XI contains requirements for
submitting documents to the regulatory or enforcement
authority or identifies documents that are subject to review by
those authorities
 BNCS has asked BPV XI to separate those requirements
 Remove them completely
 Move them to an Appendix
 Both the NRC and BPV XI will be working on a mutual
solution
 BPV XI will survey international communities to see how they
might view these regulatory requirements

Industry
◦ BPV XI Top Ten List
 It has an iterative list of the top 10 changes/issues for the
committee’s consideration
 Reviewed each meeting and revised based on industry
needs and input
 Keeps committees focused
 Coordination with NRC list and the concept is gaining
more attention
 Potentially develop a Joint Operational Plan
 Industry needs and the work provided by the members
make this plan a success

Industry (cont’d)
◦ Actions Completed
 Code Case N-770-2 was revised to incorporate optimized weld
overlay and inspection of a large diameter cold leg temperature
locations
 Code Case N-754 – optimized dissimilar metal weld overlay
used for mitigation
 Code Case N-749 – Flaw Evaluation Acceptance Criteria for
Ferritic Components based on Elastic Plastic Fracture Methods
 Code Case N-771, “On-line rules” for inservice examination
during power operation
 Still need to address Successive Examination
 Code Case N-788, Third Party NDE Certification Organization
 Third party in lieu of employer-based certification

Industry (cont’d)
◦ Develop Rules for Operational Leakage
 Phase 1 is completed which was to incorporate existing
code cases into Section XI
 Phase 2 is to define requirements to address leakage
acceptance
 Phase 3 is to look into new items, techniques, and
approaches
 Phase 2 and 3 are currently being worked in parallel

Industry (cont’d)
◦ New Working Group for Nonmetals R/R Activities
 Developing a Code Case for HDPE R/R Activities
 First issuance expected in 2013; repair by electrofusion is
targeted for 2014
 Developing a Code Case for Repair of Moderate Energy
Class 2 and Class 3 Piping using Carbon Fiber Composites
 Grass roots effort - will not use Code Case N-589, but will
apply lessons learned
 First issuance targeted for 2015
 New
Code
◦ Revision to Division 2
 A significant change was made during the year
 The change was to be able to include all reactor types
 Requirements will pertain to all reactor types
 Specific requirements for each reactor type will be
included in appendices
 Small Modular Reactors
 Implement a Reliability Integrity Management (RIM)
system
 The new Division 2 is expected to be published in the
2015 Edition

Revision of Division 2 (cont.)
◦ RIM (Reliability and Integrity Management)
 Plant design, inservice inspection, online monitoring
 Appropriate level of reliability of systems, structures and
components (SSC)
 Continuing assurance over the life of the plant that such
reliability is maintained
 Design and inspection or monitoring features important to
reliability




Design margins
Material selection
Maintenance, repair, replacement
Testing, monitoring, inservice inspection (ISI)

Revision of Division 2 (cont.)
◦ RIM (Reliability and Integrity Management)
 Determine Scope of SSCs for RIM Program
 Evaluate SSC Damage Mechanisms
 Determine Plant and SSC Level Reliability and Capability
Requirements (including beyond-design-basis events, if desired)
 Evaluate RIM Strategies to Achieve Reliability Targets
 Evaluate Uncertainties in Reliability Performance
 Determine Scope and Parameters of RIM Program
 Monitor SSC Reliability Performance and Update RIM Program
