Idaho National Labs Deep Burn Pebble Plans

This is a follow up to the Idaho National Labs achieving 19% burn of pebble fuel

Pebble bed fuel could theoretically achieve 65% burn, but would require highly enriched fuel.

Currently our plans to do include going to those ultra high burnups which would require high enriched uranium levels.

We are now focusing on two major activites:
(a) characerizing the performance of the fuel at higher temperatures that simulate off-normal conditions and
(b) demonstrating that this fuel can be fabricated at industrial scale and still perform successfully.
