Public Meeting for Abilene Christian University Fuel Qualification Methodology Whitepaper 1
NRC Staff Feedback May 28, 2025
Feedback Areas
- Fuel qualification testing timeline
- Technical areas
- Standards evaluation and applicability
- Thermophysical properties
- Fission product retention testing
- Range of testing
- Use and validation of Molten Salt Reactor Experiment (MSRE) data
- Quality Assurance 2
Fuel Qualification Testing Timeline
- NRC staff has not received confirmation that testing has been completed or a schedule with estimated completion dates.
- Fuel qualification testing is necessary to characterize fuel parameters used to support analysis in the Final Safety Analysis Report (FSAR).
- Incomplete testing has the potential to impact the Operating License Application (OLA) review.
3
Technical Areas (Part 1)
- Standards evaluation and applicability
- Demonstrate applicability of the ASTM standards to molten salt.
- Staff will evaluate application of the ASTM standards when reviewing qualification testing results.
- Many of the ASTM standards in the white paper do not reflect the current version of the standard.
4
Technical Areas (Part 2)
- Thermophysical properties
- Clear justification of the selection of fuel salt properties that support fundamental safety functions or what precision is needed for each property.
- Fission product retention testing
- Determine whether fission product retention testing is needed.
5
Technical Areas (Part 3)
- Range of testing
- Clarify which molten salt research reactor safety limits are being used for peak fuel salt temperature.
- Use and validation of MSRE data
- Provide and justify a comprehensive list of impurities and allowable concentrations 6
Quality Assurance
- The quality assurance program should be applied to the fuel salt testing program.
