Hanford Project • Part of Manhattan Project • Hanford (plutonium). • Oak Ridge (uranium). • Commissioned by U.S. • Gen. Leslie Groves • Hanford Engineer Works (Army Corps) • Expanded during Cold War • Plutonium ~60,000 nuclear weapons.
B Reactor (1944) • World’s 2nd Nuclear Reactor. • Designed by E. Fermi • Built by DuPont Corporation.
Nuclear Fission U-238 + n ⇒ U-239 (β) Np-239 (β) Pu-239
GE Company: 1945-1977 • Processing plutonium for U.S. nuclear arms. • In addition to B Reactor: • 221-T Plant (1944) • D Reactor (1944) • F Reactor (1945) • H Reactor (1949) • C Reactor (1952) • N Reactor (1963) + 4 others …
DOE (since 1977) • Reactor lifespan ~22 years.
DOE (since 1977) • Reactor lifespan ~22 years. • 22 Years??????
Environmental Hazards • 55 million gal of radioactive waste from fuel rods. • 1 million gallons in groundwater. • Unknown amount in Columbia River.
Concerns • Increased radioactivity in Columbia. • Asthma in Tri-Cities area. • Different types of cancer.
Nuclear Glass Solution • Certain isotopes are mobile in water. • Need solidified process. • Amorphous borosilicates (glass).
How to Make Glass • Obtain silica (sand) • Add sodium carbonate and calcium oxide • Add lead and sulfur (to color the glass) • Put in crucible and heat to liquid (2,300 F) • Remove bubbles • Shape and cool
Nuclear Glass-Making • Vitrification : • Combine waste with soil (silicon-base) • Heat to 2,100 F. • Cool in steel canisters and store underground.
Not In My Back Yard • Burial at Yucca Mountain has been cancelled. • YM could only hold 77,000 tonnes. • Safety concerns.
A Difficult Problem • Not cost-effective. • No one wants the storage near them. • Radioactive material does not decay quickly. • No single company wants responsibility.
