  • Production of radioisotopes with a high specific activity by isotopic conversion
    Patent number: 6208704
    Abstract: An apparatus, and method, are disclosed for producing a high specific activity of a radioisotope in a single increment of target material, or sequentially within in-series increments of target material, by exposing a targeted isotope in the target material to a high energy photon beam to isotopically convert the targeted isotope. In particular, this invention is used to produce a high specific activity of Mo99, of at least 1.0 Ci/gm or preferably at least about 10.0 Ci/gm, from Mo100.
    Type: Grant
    Filed: July 15, 1999
    Date of Patent: March 27, 2001
    Assignee: Massachusetts Institute of Technology
    Inventors: Lawrence M. Lidsky, Richard Lanza

  • Dual brayton-cycle gas turbine power plant utilizing a circulating pressurized fluidized bed combustor
    Patent number: 5544479
    Abstract: A gas turbine power plant operating on a dual Brayton cycle and utilizing a circulating pressurized fluidized bed combustor is disclosed. An open Brayton cycle is provided in which the hot flue gas from the fluidized bed combustor is expanded to extract work to drive compressors to supply combustion air for the fluidized bed combustor and to drive an electric generator to produce electricity. The residual heat of the flue gas exhausted from the open Brayton cycle can be utilized for heat cogeneration at high power-to-heat ratios. A closed Brayton cycle is also provided, the working medium of which is heated in an indirect heater of the circulating pressurized fluidized bed combustor and expanded to extract work to drive another electric generator. The air supplied by the open Brayton cycle is also used to fluidize the heated particles in the indirect heater.
