Yomiuri ShinbunThe government will likely go ahead with a plan to spray resin inside the troubled Fukushima No. 1 nuclear power plant, which it hopes will contain the spread of radioactive substances, sources said Wednesday.
The government has begun full-fledged discussions on different plans to stop the spread of radioactive substances that have been leaking continuously from damaged reactors at the plant run by Tokyo Electric Power Co
...
The plan involves using a remote-controlled robot to spray resin over about 80,000 square meters inside the 120,000-square-meter facility. The areas to be sprayed were contaminated by radiation from
debris scattered by several hydrogen gas explosions in the days after the March 11 earthquake.
Synthetic resin would likely be used, possibly Kurita Water Industries Ltd.'s Kuricoat C-720 Green. The product is usually used to prevent dust and sand from being blown off reclaimed and developed land. Coating the debris with resin is expected to prevent the radioactive materials from spreading into the air.

The government is now considering building temporary facilities for storing the contaminated water inside the plant and other options.
These plans are being devised by a radiation control team comprised of senior officials from the Japanese and U.S. governments, nuclear experts, and personnel from the SDF and the U.S. military. The team is led by Sumio Mabuchi, a special adviser for the prime minister. The sources said the team decided to go ahead with the resin spraying at its meeting Tuesday.
The measures, however, are only stopgap, and the government said it would come up with more permanent solutions to contain the radioactive materials after temperatures in the nuclear fuel rod pools fall and the reactors stabilize.
