Nur mit Bolzen genietet und nicht geschweißt

“Only riveted together and not welded,” reporter Johannes Hano’s description of many of the ~1000 containers in the leaky tank farm behind the “nuclear ruin” of Fukushima out of which tons of radioactive water have been seeping every day. On 01 Sep 2013 the Guardian.co.uk reported remeasuring had found the water in at least one of these tanks was radioactive enough to kill you within four hours. Also, employees helping clean up the mess for the past two and a half years have not been equipped with dosimetric gear showing them this danger.

A local fisherman based 40 kilometers south of the plant said, “We were just getting ready to steam out when suddenly the news was announced that the ocean had been poisoned with radioactivity, again. First they tried to verarsch us about it. They said only 120 liters had leaked out! Then suddenly it was 300,000 liters. I want to puke.”

On 02 Sep 2013 Tepco was forced to admit they’ve been actively piping some radioactive water into the Pacific Ocean rather than capturing all of it and passively letting some leak out into the sea (or capturing all of it and storing it securely, which is what they were claiming to do). They don’t have enough holding capacity for the site’s contaminated water.

Spiegel.de reported Tepco has been producing ~400 tons of new radioactive water daily that’s pumped each day through the still-seething three reactors that experienced partial meltdowns. A lot of that water just flows down through the buildings, becoming contaminated with cesium, strontium and tritium. They reuse some of it after running it through “ion exchangers” that remove some cesium, but still an extra 400 new tons of water are contaminated each day that way. There’s also an “underground river” flowing beneath the plant from the inland mountains to the sea, exposing about a thousand new metric tons of groundwater to radiation each day. Tepco wants to artificially freeze the earth around the plant into an underground ice wall but doubts have been expressed about that plan, especially after one rat was said to have caused a power outage at Fukushima Daiichi this summer.

As we searched the media for relevant science information immediately after the tsunami and explosions at Fukushima Daiichi, the Rachel Maddow Show’s reporting seemed relatively good in the first fortnight after the disaster. TRMS interviewees said the partial meltdowns at the reactor cores could create a caustic and radioactive chemical brew that could eat through the reactor and building floors and on down into the ground an unknown distance, pulled by gravity and presumably whatever more easily dissolved or traversed materials the soup encounters.
