NRC Perspective on Experimental Needs Dr. Mirela Gavrilas Director, Division of Safety Systems Office of Nuclear Reactor Regulation 1
Outline
- NRC needs and priorities
- New fuel technical basis development
- Engagement with industry
- Loss of the Halden Reactor
- Moving forward 2
NRCs Needs and Priorities
- NRC is committed to continued participation in fuel safety research
- Developing staff knowledge and expertise
- Maintaining awareness of potential safety issues
- NRCs irradiated materials research needs support safety during continued plant operation
- Priorities
- ATF concepts transient and DBA behavior
- Fuel performance beyond current burnup limits
- Highly irradiated stainless steels welds 3
New Fuel Technical Basis Development 4
Engagement with Industry
- Industry responsibility to develop fuel qualification plan and testing matrix for ATF
- NRC encouraging early, robust engagement through ATF project plan
- Experimental testing requirements/timing can vary:
- Departure from current technology/knowledge base
- Operational envelope (e.g., burnup, crediting additional ATF coping time)
- Strategy for licensing
- Use of advanced modeling and simulation capabilities 5
Loss of Halden Reactor
- NRC confidence in Halden data
- Halden Reactor Project community
- Technical expertise and knowledge base
- Funding model
- Potential gaps
- Irradiation of fuel segments in BWR conditions
- On-line, in-pile data collection
Moving Forward
- NRC is committed to participation in a Halden Reactor Project successor program
- Priority is research related to safety of currently licensed fuel, testing to support future licensing actions (e.g., ATF), and irradiated materials testing
- Contribution commensurate to pertinence to NRC mission
- Engaging vendors to understand testing and licensing strategies
- Open to consider innovative approaches 7
