A Japanese Foreign Ministry spokesman said the plant will reprocess between 5,000 and 7,000 tons of radioactive waste a year.
The building costs will be drawn from a $100 million aid package Japan set up last November with Russia to help dismantle nuclear weapons held in the former Soviet Union.
The spokesman said Japan did not expect building costs to exceed the fund and hoped to have the results of the bid by the end of next month or early December.
The storage and treatment plant will be placed on a barge and will be moored at a shipyard used for decommissioning nuclear-powered submarines near the Far Eastern port of Vladivostok, the foreign ministry said in a statement.
Russia dumped about 800 tons of low-level nuclear waste in the Sea of Japan last October provoking an outcry in Japan and South Korea.
The move prompted Japan to provide assistance to nations of the former Soviet Union to dismantle unnecessary nuclear weapons.
A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
