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
