MIT presentation — Ken Buesseler, Woods Hole Oceanographic Institution, Oct 24, 2013 (at 38:15 in): I was quoted as saying it’s silly to think it’s not getting out of the harbor. It’s getting out of the harbor, it’s measurable […] Last month we were there, our highest number is 150 Bq/m³ [...] I have seen some of the highest numbers in the Tepco data in the last month at the coast recently of about 1,000 or 2,000 Bq/m³ for cesium.
Slide from Buesseler’s presentation: Highest Cs closest to shore, associated with locations of higher groundwater input — Even higher in September 2013
NHK, Jan. 28, 2014: [Tepco] is to begin work at the Fukushima Daiichi nuclear plant to stop radioactive wastewater from flowing into the sea. The task of creating underground frozen walls is due to start at the Number 2 and Number 3 reactors on Wednesday. Massive amounts of water are being poured into the reactors [...] and is leaking from the damaged reactor containment vessels. The water has accumulated in the reactor buildings, adjacent turbine buildings and underground tunnels. TEPCO believes the water is leaking from the tunnels, seeping into the ground and reaching the sea. [...] Engineers cannot go there because of the radioactive water [...] TEPCO is also digging wells in the compound to see whether water is leaking directly from the buildings.
