The ocean is still considered as a trash can. Radioactive releases by Japan are increased by a decrease of vigilance. What is occurring in the Pacific Ocean is probably inevitable. However it is not excusable nor should it be viewed as routine as many scientific experts in dispersion and farfetched comparison are currently stating. This type of practice would be impossible in the North East Atlantic. Contracting Parties to the OSPAR Convention follow carefully step by step the slow progression of iodine 131, of cesium 137 and of plutonium released by nuclear installations along the Channel and the North Sea to the Arctic Ocean.

Thanks to the technological help from France, in 1970 in Tokaï-Mura, south of Fukushima, Japan opened a pilot irradiated fuel-reprocessing factory.

In 1987, Cogema (COmpanie GEnérale des MAtières nucléaires) signed a contract for 1.4 billion francs, equivalent to 213 million Euros, to help construct a new reprocessing factory in Rokkasho-Mura, north of Fukushima – a replica of la Hague’s inland factory near Cherbourg. It should have started service in 2005, but today we are still waiting. As a result, the Fukushima-Daiichi accident site also houses a pool of irradiated fuel, common to the six reactors. The pool is supersaturated and serves as buffer storage pending the start of the Rokkasho-Mura factory. The vice president of Tepco, Tokyo Electric Power Company, declared in 2002 while the local and hostile nuclear referenda were multiplying that “the extraction of plutonium was vital.” The Rokkasho factory must then serve to extract the irradiated plutonium fuel and to re-inject the new fuel associated with the enriched, mixed oxide uranium plutonium fuel. In waiting for the eventual opening of the Rokkasho-Mura factory, France furnished the Japanese reactors with MOX. On March 10th 2011, the day before the earthquake, Areva, the leading French nuclear company, announced to the French High Committee for the Transparence of Information on Nuclear Safety the imminent departure of a new sea transport of MOX between Cherbourg and Japan, which would include fuel for the 3rd reactor at Fukushima-Daiichi.

The extravagant iodine-131 content around the area of the Fukushima Daiichi Nuclear Power Plant is a result of leaching of emergency cooling waters used by firefighters and emergency workers. At Fukushima and at French nuclear facilities, there is no collection device for these cooling waters whereas all warehouses storing chemical products are legally bound to be equipped with a collection basin of polluted water used to extinguish fires. The iodine-131 content is also a result of the consequent radioactive dust deposits of the explosions in the heights of the nuclear islets, namely the buildings, the reactors, and the pools. The iodine-131 is one of the indicators of pollution. Other measures will later show similar deviations from standards for cesium-137 and plutonium.

Press release n°11

Several species of large and small cetaceans frequent the coastal waters of eastern Japan and are in the area affected by the liquid and atmospheric radioactive effluent discharged by the Fukushima-Daiichi nuclear power plant.

In particular, this concerns sperm whales, Bryde’s whales, Minke whales, Dall’s porpoises and dolphins. Their lifespan, diet and position at the top of the marine food chain expose them all to the bioaccumulation of chemical and radioactive pollutants.
