MARVEL team shares lessons learned through microreactor development
On June 1 at the American Nuclear Society’s Annual Conference in Denver, Colo., a team from Idaho National Laboratory presented a session titled “Lessons Learned from MARVEL Reactor Fabrication.” The presentation highlighted challenges that arose as they moved from design to manufacturing and assembly, with a focus on reactor part fabrication, Stirling engine implementation, and reactivity control system development.

The accident at Three Mile Island Unit 2 left the reactor core in a severely degraded condition. Core removal methods and equipment designed for an undamaged reactor refueling required extensive modification. Fuel debris containments, tooling, contamination control, and water processing methods were tailored to known and postulated core conditions using primarily manual rather than robotic methods. Flexibility was a key element in the equipment design since little definitive data on reactor physical conditions were available.
