The 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.
It is believed spraying resin would minimize the spread of radioactive substances, which would allow repair work at the plant to proceed more smoothly, the sources said. Efforts to restore the reactors’ cooling functions have seesawed repeatedly, with the detection Wednesday of radioactive iodine-131 at levels 3,355 times the legal limit in seawater near the plant being the latest wrench in the works.
Spraying resin on debris inside the plant could begin as early as Thursday, the government sources said. The operation would last for about two weeks, they said.
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.
