College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Discussed are the advantages of using fusion neutrons for breeding special nuclear materials and tritium. Monte Carlo calculations were used to identify both fissionable and nonfissionable materials that multiply neutrons and increase breeding ratios. Fissionable multipliers also greatly multiply the neutron energy. A generic blanket design that utilizes 238U as a neutron multiplier is decribed and compared to an ideal infinite-medium blanket. Time-dependent calculations show gradual improvement of performance during the lifetime of the blanket. The blanket analyzed here is compatible with a reaction chamber that uses high velocity lithium, held on the wall by centrifugal acceleration, to protect the wall from pellet explosions.
