Deal reached to pump Hanford tank

A deal has been reached between officials for the Hanford Nuclear Reservation and the state of Washington to remove nuclear wastes from a leaking tank.

The deal was announced Monday between the Office of River Protection, Washington River Protection Solutions and state regulators.

Under the agreement, pumping of a double-walled tank known as AY-102 will begin no later than March 4, 2016.

Washington River Protection Solutions says it continues to monitor AY-102 and has found no evidence of waste leaking into the environment.

Hanford officials and the state have been in settlement talks since July.

The Energy Department discovered in 2012 that radioactive waste was leaking from the interior shell into the space between the shells. The waste is left from the past production of plutonium for nuclear weapons.
