NRC Standards Forum:
NRC Endorsement of ASME BPVC Section III, Division 5 Andrew Yeshnik September 11, 2018
Background - FY16-17 Implementation Action Plans (July 2017) to support NRC Vision and Strategy (December 2016)
- 1. Acquire/develop sufficient staff knowledge, tech. skills, capacity to perform non LWR regulatory reviews
- 2. Acquire/develop sufficient computer codes/tools to perform non LWR regulatory reviews
- 3. Establish a more flexible, RIPB nonLWR review process within the bounds of existing regulations, incl. CDAs, staged reviews
- 4. Facilitate industry codes & standards development needed to support the nonLWR lifecycle, including fuels & materials
- 5. Identify & resolve techinclusive nonLWR policy issues
- 6. Develop a structured, integrated communications strategy for internal and external stakeholders with nonLWR interests)
NRC Endorsement of ASME BPVC Section III, Division 5
- Current nuclear power designs operate within a thermal range of 275°C to 315°C.
- Advanced reactor designs have operating thermal ranges that vary widely between 480°C and 1000°C.
- There is no NRCendorsed code of construction for nuclear reactors operating above 425°C (800°F).
- American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME BPVC)Section III, Division 5 provides design, construction, certification, and quality assurance rules for metallic components operating in excess of 800°F, graphite core structures, and ceramiccomposite components.
- A letter dated June 21, 2018 from ASME (ML18184A065) requested that the NRC review and endorse the 2017 Edition of ASME BPVC Section III, Division 5 (NRC Response Letter: ML18211A571)
Review and Endorsement Process
- NROLead with support from RES/DE and NRR/DE
- Anticipated Product (August 2020): A draft regulatory guide for public comment that includes the 2017 ASME BPV Code Section III, Division 5 as an endorsed method of constructing Advanced Reactor Designs, subject to any conditions the staff deems necessary.
- The NRC is participating on two ASME/NRC task groups:
- Metallic Materials
- Graphite and Ceramics
- Stakeholder engagement throughout the review
Review and Endorsement Process Current Status:
- The endorsement team has started Task A, Project Planning
- Establishing the scope, schedule, and NRC points of contact
- Process: Review of Low Temperature and General Requirements (QA) Rules (Task B)
Project Planning Review of High Temperature Metal Rules (Task C)
(Task A) Review of Graphite Rules (Task D) Draft RG Review of Code Cases (Task E) (Task F)
