Heater Design

Heater Design

• Test heater-rod built and confirmed to meter out correctly.

• Cladding ID = 0.305 in• Cladding OD = 0.375 in

Questions for discussion

• TRTL bounds (known and present) pre-conceptual capabilities of TRTL.• What transients (RIAs) does the INL believe the TREAT can run• How do these tie into the experiment• What are the most impactful power ramp-rates for us to consider?• What are the most impactful fluid temperature conditions to consider?• What are the most impactful system pressure conditions to consider?

• Heater• What timelines are associated with AREVA’s ability to provide sleeves?• What are the limitations on dimensionality?
