Regarding Tepco’s recent statement that the fuel assemblies in the Unit 3 pool could have been damaged by shock when the steel beams or 30-ton fuel exchanger fell, Fairewind’s chief engineer Arnie Gundersen writes in to ENENews:
Another possible reason for damaged U3 racks could be a prompt, moderated criticality. What does TEPCO know about the U3 racks that they have not yet shown photos of? The photos I have seen are very murky, very blurry. I wonder if TEPCO has better quality pictures?
