Tepco now admits that groundwater flowing into Fukushima reactors is radioactive

water-radiationFukushima plant operator reverses claim groundwater not contaminated (Reuters) Reporting by Risa Maeda; Writing by Aaron Sheldrick. 4 June 13- Tokyo Electric Power Co said on Tuesday it had detected radioactive caesium in groundwater flowing into its wrecked Fukushima Daiichi plant, reversing an earlier finding that any contamination was negligible.

The announcement is yet another example of Tokyo Electric initially downplaying a problem, only to revise its findings because of faulty procedures. It casts further doubt over its control over the cleanup of the worst nuclear disaster since Chernobyl in 1986.

“Once again, they’ve missed something they should be aware of,” said Atsushi Kasai, a former researcher of radiation protection at the Japan Atomic Energy Research Institute…… The discovery that groundwater is also being contaminated before it enters the damaged reactor buildings compounds the problems for the company known as Tepco. It has been trying to convince local authorities and fishermen that the groundwater has negligible levels of contamination and is safe enough to be dumped into the ocean.

About 400 tonnes of groundwater flow daily into the reactor buildings only to be mixed with highly contaminated water that comes from cooling the melted fuel.That water has to be stored in tanks and pits. Leaks in the latter in recent weeks have prompted it to scramble to build more tanks.

Tepco on May 30 told fishermen that radioactive caesium in the groundwater was at a level that could not be detected.But the results were false as they were skewed by using procedures that failed to take into account the background radiation at the damaged plant, Tepco told Reuters on Tuesday. The findings were earlier reported by local media.

“We’ll have to correct the way we analyse sample data,” said Mayumi Yoshida, a Tepco spokeswoman.The revised results still show the radiation level to be below what Tepco views as the upper limit for releasing groundwater — one becquerel of caesium 137 per litre. A becquerel is a measure of radioactivity.

Follow up analysis showed the groundwater had 0.22 becquerel of caesium-134 per litre and 0.39 becquerel of cesium-137 per litre rather than an undetectable amount, Yoshida said……http://uk.reuters.com/article/2013/06/04/uk-nuclear-japan-tokyo-electric-idUKBRE95309020130604
