The government has started soliciting candidates in and outside Japan for projects to help it separate tritium from the contaminated water building up at the Fukushima No. 1 nuclear plant.
Accepting candidates until July 17, the government will pay up to ¥1 billion per project to build a facility and conduct an experiment by using tainted water from the plant.
Tokyo Electric Power Co. is test-running a trouble-plagued system that is reputed to remove 62 different types of radioactive substances from the contaminated water except tritium.
