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
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
Section XI Update
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
Section 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
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
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 2015 Edition
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)
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
