http://ThoriumRemix.com/ Hi my name is Grant Buster. I'm a graduate student here at the thermohydraulics laboratory at UC Berkeley. I work to develop a fundamental understanding of how pebble fuel moves through a reactor core. This is kind of the central column and this would be rotated around it's kind of an annulus- a doughnut-shaped core. Some will exit the reactor core quite quickly, while others will be held up for you know maybe months at a time. Every time we defuel a pebble we can assay these pebbles using gamma ray spectroscopy, to discern what the burn up is of this pebble. And whether it should be placed back into the core or whether it should be put in storage.
