100 Area

During Hanford''s mission of plutonium production from 1943 through 1987, tons of plutonium were produced as a result of hundreds of thousands of tons of metal uranium fuel rods being subjected to the nuclear chain reactions in the reactors.

Uranium

Uranium trifluoride is most conveniently prepared by reduction of UF 4 with finely powdered uranium. Three methods of preparation of uranium fluoride have been investigated: (1) Palmer 67 reported the reduction of uranium tetrafluoride by hydrogen at 1000 C in molybdenum boats using stainless-steel tubes (UF 4 (s) + 1/2H 2 ↔ UF 3 (s) + HF), (2) treatment of uranium trichloride with hydrogen ...

Uranium Enrichment/Fuel Fabrication

The plant, which at one time processed uranium to use in fuel rods for nuclear power plants, was closed in 1993 due to contamination. John Ellis, the one-time president of Sequoyah Fuels and now the demolition contractor, said the dismantling and disposal of the plant is part of a Nuclear Regulatory Commission (NRC) approved plan.

Breeding in the Reactors at Hanford

The water then was passed directly through long, horizontal tubes in the reactors, where the solid, Al-Si-jacketed uranium fuel rods underwent active neutron bombardment. From there, the water was pumped out the back of the piles, left for a brief time (30 minutes to 6 hours) in retention basins to allow for short-term radioactive decay, and then returned to the Columbia River.
