‘Nuclear Fuel in a Reactor Accident’ — Peter Burns, Rodney Ewing, Alexandra Navrotsky, 2012: […] The long-lived fission products and transuranium elements [Plutonium, etc.] within damaged fuel remain a concern for millennia. […] [Conditions after a nuclear accident] are often unanticipated […] the movement and redistribution of fuel and moderators create the added concern of continued or sporadic criticality […] years may pass before remotely controlled instruments can reveal the final condition and configuration of the fuel. […]
AAAS Science Podcast Interview with Peter Burns: In terms of the damaged fuel […] what has not really been studied is the longer-term fate of that material [after] everything has melted into a big blob. We know very little […] about how water, or even just the air will interact with that over time. […] We need to take very seriously the development of knowledge about how […] melted nuclear fuel moves in a reactor containment vessel [...] >> Full interview available here
NHK World, May 21, 2014 (at 2:00 in):
- NHK: Engineers face their hardest challenge at the nuclear plant, they have to deal with the inside of the reactor containment vessels. […] The cleanup process will not be complete until all of the debris is removed.
- Naohiro Masuda, Tepco Decommissioning Chief: We certainly have a difficult path ahead. I think we’ll be able to move forward if we can find out where the debris is and what the current conditions are.
