ENENews: Officials now say Fukushima reactor with MOX fuel “leaked directly from containment”


Officials now say Fukushima reactor with MOX fuel “leaked directly from containment” — TV: Contamination of environment was due to “failure of vessel” — Experts: This has caused additional worries because MOX is more “radioactively aggressive” due to plutonium content (VIDEO)

NHK, Dec 17, 2015 (emphasis added): [TEPCO] says radioactive fallout that polluted the environment in mid-March of 2011 was likely caused by a leak directly from a containment vessel of the facility’s No.3 reactor. Officials… on Thursday reported their latest findings on what happened at the plant… They concluded that radioactive contamination of the environment between the night of March 14th and the 16th was likely caused not by the vent operations but failure of the vessel. They said the vessel likely lost airtightness due to heat from nuclear fuel, leading to the direct release of radioactive substances into the environment.


NHK transcript, Dec 17, 2015: [TEPCO] said the substances in one of the reactors probably leaked directly from the containment vessel… They suspect the heat of fuel caused the containment vessel to lose airtightness.

TEPCO, Dec 17, 2015: A significant release of steam from the night of March 14 to March 16, 2011 is believed to have been responsible for contamination to the surrounding environment of Fukushima Daiichi. The investigation reports that the primary containment vessels in Units 2 and 3 did likely lose leakage resistant properties by March 15 and had been in a condition where radioactive materials could leak directly from them. It is therefore presumed the environmental contamination outside Fukushima Daiichi during that period was caused by steam leakage directly from the primary containment vessels and not from the vent.

TEPCO, Dec 17, 2015: Leakage and release of a large amount of steam from the Unit 3 Reactor Building — The PCVs of Units 2 & 3 lost the airtightness in the end, which is confirmed by the fact that steam escaped from the Reactor Buildings. Analysis of the behavior of the pressure in the PCVs and the situation at the time of the accident has revealed that the environmental contamination from the night of March 14 to March 16 occurred by steam leakage together with radioactive materials directly from the PCVs not from the vent.

UBS Investment Research (via WikiLeaks), Apr 2011: Of particular concern was Unit 3, because, since September 2010, the plant had been fueled with mixed oxide, or MOx… Use of MOx heightened fuel risk — Fukushima Daiichi Unit 3 was fuelled with mixed oxide (MOx), which is about 93% uranium and 7% plutonium. This has caused additional worries for TEPCO and the government, because MOx is more radioactively aggressive. We think national nuclear safety reviews might consider restrictions on its use.

NHK, Apr. 10, 2015 (emphasis added): About 160 dolphins washed ashore on a beach in Ibaraki [50 miles south of Fukushima border]… A local aquarium says this type of dolphin… is usually found in deeper waters. It says it is unusual for so many to be washed ashore.

Japan Times, Apr 11, 2015: 149 melon-headed whales [washed up] in Hokota. Seven more were stranded in nearby municipality of Kashima.

AFP, Apr 10, 2015: Television footage showed several animals from the large pod had been badly cut, and many had deep gashes… “We see one or two whales washing ashore a year, but this may be the first time we have found over 100 of them on a beach,” a coastguard official told AFP… Several animals were writhing in a futile effort to move.

Inquisitr, Apr 10, 2015: A Japanese coast guard official has said that he is witnessing this phenomenon for the first time in his life… According to BBC News, these species of dolphins are usually only found in the deep waters of the ocean. It is extremely rare for them to show themselves up on the beach… this might be the biggest single case of mass beaching of dolphins that have been reported from Japan… This case of dolphins beaching themselves is eerily similar to another phenomenon that has been noted recently… young sea lion pups ending up on the beach – starving and dazed.

Mainichi, Apr 11, 2015: Kashima Coast Guard station transported and released three of the melon-headed whales… but most of the dolphins died and were buried on the beach… According to Toshiya Kishiro, head of the whale resources group at the National Research Institute of Far Seas Fisheries… a possible reason for this most recent beaching is that the dolphins had parasites in their inner ears.

AP, Apr 10, 2015: Tadasu Yamada, a cetacean expert at the National Museum of Nature and Science [said] the dolphins may have had a physiological or psychological problem and faced an unknown threat and panicked…

Yamada: “We don’t see any immediate signs of diseases on their bodies, such as cancer. We want to figure out what killed these animals.”

Slate, Apr 10, 2015: Many animals that become stranded are later found to be ill.

AFP, Apr 11, 2015: The mass beaching… has fuelled fears of a repeat of [the 2011] earthquake… a flurry of online commentators pointed to the appearance of around 50 melon-headed whales… six days prior to the monster quake… More than 100 pilot whales died in a mass stranding on a remote New Zealand beach on February 20, 2011, two days before a large quake… Japanese officials nevertheless tried to calm fears and insisted there was no scientific data to prove the link.
