F2. Nuclear fuels fabrication and characterization

(Lecture: 12h, Practicals: 8h), S. Dubois (CEA)

Lecture:

  • Fabrication and properties of oxide powders.
  • Fabrication of UO2 and MOX pellets:
    • sintering process,
    • role of oxygen potential.
  • Fabrication of rods and subassemblies.
  • Fabrication of fuel particles for HTR.
  • Characteristics and fabrication process of alternative fuels:
    • Carbide,
    • Nitride,
    • Metal alloys.
  • Characterization methods and measured properties of fresh nuclear fuel (structure, density, porosity, chemical composition, O/M ...).

Practicals, including a short visit of the LEFCA laboratory (choice to be made by groups of 4 to 5 students):

  • Characterization methods in the UO2 Laboratory,
  • Thermo-mechanical and micro-structural characterizations,
  • Fabrication control measurements,
  • Chemical analyses of fuels.
