UPI, August 22, 2013: TEPCO said late Wednesday that radiation levels in groundwater are so high the most likely explanation is that radioactive water from the plant’s cooling system is leaking from the reactors into basements and mixing with water from local aquifers,The Japan Times reported.
World Nuclear Industry Status Report 2013: An expert reactor engineer estimated the amount of radioactivity that had seeped into the water that fills the basement of the reactor buildings [...] as of 20 November 2012 [is] Cesium-137: 276 PBq (i.e. 40 percent of the reactor core inventory) [...] about 2.5 to 3.3 times, depending on the estimate, the total amount released into the environment from the Chernobyl accident.
Bloomberg News, August 22, 2013 – (At 2:15 in) Host: Is there any risk that gets into the downstream water supply? Could this flow downstream to Tokyo and present a big risk? [...] Michael Friedlander, Nuclear Engineer: I’m not a hydrologist [...] But certainly anytime you have contamination in the aquifer by diffusion process and by the normal underground flows of water, who knows where it’s going to end up at.
