  • Method for processing spent nuclear reactor fuel
    Patent number: 4278559
    Abstract: A method and apparatus for processing spent nuclear reactor fuel wherein plutonium is continuously contaminated with radioactive fission products and diluted with uranium. Plutonium of sufficient purity to fabricate nuclear weapons cannot be produced by the process or in the disclosed reprocessing plant. Diversion of plutonium is prevented by radiation hazards and ease of detection.

  • Method and apparatus for reducing the power level in a nuclear reactor during temperature transient
    Patent number: 4227967
    Abstract: Apparatus for reducing the power level in a nuclear reactor during a transient increase in temperature of the primary coolant. The apparatus includes a neutron absorber and a thermally elongatable member adapted for moving the absorber into closer proximity with the core. The elongatable member is sensitive to the temperature of the primary coolant and moves the absorber by its thermal elongation. The elongatable member includes means for amplifying its thermal elongation so that the motion of the absorber member is amplified.
