Mainichi Shimbun, Feb 27, 2017 (emphasis added): Search for melted nuclear fuel at Fukushima plant’s No. 2 reactor faces obstacles… so far, they have been unable to identify the location of the melted nuclear fuel… a number of unexpected problems emerged… Heavy machinery giant IHI Corp.’s Keizo Imahori, 38, who oversaw the mechanical boring of the containment vessel in December 2016, explains that, “A number of unexpected dents were found on the floor of the nuclear reactor building.” This was a surprising discovery for Imahori and his team… As an emergency measure, 1-meter by 1-meter iron sheets were used to cover the dents… [T]he Fukushima No. 1 Nuclear Power Plant [is] somewhat like a “burning house” Yasuo Hirose, of IHI Corp., states…

IEEE, Feb 14, 2017: Will Davis, a former U.S. Navy reactor operator, and a communications consultant to the American Nuclear Society [said] “Not only is the presence of localized [radiation] point-sources possible, but there is also the possibility that streaming of radiation is taking place. In other words, we cannot say that all of the radiation in the containment vessel is coming from one unified lump of damaged fuel in the reactor vessel, and perhaps from a second unified lump sitting under it.”

Asahi Shimbun, Feb 19, 2017: Radiation levels at Fukushima reactor puzzle nuclear experts… [The robot’s] short-lived mission raised puzzling questions that could derail existing decommissioning plans… [It found] radiation measurements that indicate [TEPCO] was too optimistic about the state and location of the melted fuel… [It] may be spread out all over the reactor’s containment vesselthe situation within the reactor is much worse than expected. And a fresh investigation into the reactor is now nowhere in sight… [A]n official close to TEPCO said, “I had great expectations for [the robot] Sasori, so I was shocked by how it turned out.”… “Instead of directly landing on the rail, the melted nuclear fuel may have flown off after it reacted violently with the concrete, which had a high moisture content, at the bottom of the containment vessel, just like what happens when lava pours into the sea,” [Hiroaki Abe, professor of nuclear materials at the University of Tokyo who has studied TEPCO’s footage] said…
