4. ASME Section XI
Division 1: Rules for Inspection and Testing of Components of Light-Water-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 Liquid-Metal-Cooled Plants (2001 Edition with the 2002 Addenda)

5. Section XI Update 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

6. Section XI Update 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

7. Section XI Update 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

8. Section XI Update Industry (cont’d) Actions Completed
Code Case N 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

9. BPV XI Update 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

10. BPV XI Update 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

11. BPV XI Update 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 Edition

12. BPV XI Update 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)

13. BPV XI Update 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
