Characterization of minor actinide mixed oxide fuel

Minor Actinide Transmutation

Characteristics of Minor Actinide Transmutation in Minor Actinide Burner Reactors and Power Reactor

One of the techniques of minor actinides transmutation is to recycle these nuclides into fission reactors. Two concepts of a minor actinides burner reactor with very hard neutron energy spectrum as well as very high neutronjlux me discussed. The fuel cycle facilities for these burner reactors am assessed to discuss the technical feasibili~ of these reactors. Transmutation of minor actinide in b...

Present Status of Minor Actinide Data

Minor Actinide Destruction in Dedicated Reactors

The neutronic performance of small size critical dedicated burners is investigated here according to the type of recycling performed (MA supply alone or together with some fissile element), the nature of the possible fissile supply (Pu, enriched U, U bred from Th), the coolant type (sodium or lead). The main neutronic parameters are given, such as reactivity coefficients, together with mass bal...

In Vivo Calibration Measurements for Mixed Oxide Nuclear Fuel

Mixed oxide (MOX) nuclear fuel containing enriched uranium and isotopes of plutonium presents a challenge for monitoring occupational exposure using direct in vivo measurements because photons from U and Am will confound evaluation of plutonium in the lungs. MOX is a unique blend of enriched uranium and plutonium that can be used in place of traditional enriched uranium fuel in commercial press...
