Radiation near Japan reactors too high for workers

TOKYO (AP) – A pair of thin robots on treads sent to explore buildings inside Japan’s crippled nuclear reactor came back Monday with disheartening news: Radiation levels are far too high for repair crews to go inside.
Nevertheless, officials remained hopeful they can stick to their freshly minted “roadmap” for cleaning up the radiation leak and stabilizing the Fukushima Dai-ichi plant by year’s end so they can begin returning tens of thousands of evacuees to their homes.
“Even I had expected high radioactivity in those areas. I’m sure (plant operator Tokyo Electric Power Co.) and other experts have factored in those figures when they compiled the roadmap,” Chief Cabinet Secretary Yukio Edano said.
Officials said Monday that radiation had spiked in a water tank in Unit 2 and contaminated water was discovered in other areas of the plant. They also described in detail for the first time the damage to fuel in three troubled reactors, saying pellets had melted.
That damage – sometimes referred to as a partial meltdown – had already been widely assumed, but the confirmation, along with the continued release of radiation from other areas, serves to underscore how difficult and how long the cleanup process will be. In fact, government officials themselves have acknowledged that there are still many setbacks that could crop up to slow down their timeline.
