Japan Times (Abridged translated article from Sentaku Magazine), Nov. 17, 2013: [Toshio Kimura, a former Tepco plant engineer who worked at Fukushima Daiichi for 12 years] is strongly of the view that pipes in the plant were damaged seriously by the quake before a subsequent tsunami [...] “So I demanded that Tepco release the relevant data [...] it was found later that the data did not represent the whole data. [...] Analysis of the data showed [...] the core flow [of coolant] fluctuated and eventually became less than zero [...] before the nuclear power plant was struck by the tsunami. Kimura believes that piping rupture was the very cause of the loss [...] a pump designed to draw up water from the bottom of the containment vessel seems to have been activated frequently, indicating that damage to piping caused coolant to leak and accumulate at the bottom of the vessel. [...] radioactive contamination was taking place at a much faster rate than was estimated by Tepco. [...] a plant operator tried to enter into the reactor building at 5:19 p.m.[but] the dose of radioactivity was too high [Tepco has claimed the reactor water level was at the top of nuclear fuel at 5:46p]. This shows that the meltdown was taking place earlier than Tepco estimated. This corroborates Kimura’s inference that immediately after the earthquake, piping was damaged and coolant started leaking, thus rapidly lowering the reactor water level and igniting the meltdown. [...] It likely will not be long before “lies” by Tepco are brought to light.
WERU News Report, August 7, 2013 — Dean Wilkie, nuclear reactor operations, management, construction and plant engineering at a U.S. Department of Energy test reactor (at 12:00 in): I think all the units sustained damage from the earthquake. I do believe that all the units suffered by having equipment failures, perhaps pipe breaking — different things off of the reactor vessels. Each one of those makes the situation worse from an accident standpoint.
