Date: Thursday, Feb 3rd
Presenter: Alexei Soldatov and Anh Mai, Nuclear Engineering, Oregon State University
The presentation on the seminar will be focused on the actual issues related with nuclear fuel martial studies. The presentation will provide basic information about nuclear fuel, nuclear, chemical and structural changes in the nuclear fuel resulted from nuclear fission and irradiation of the nuclear fuel. The current limiting parameters and factors will be discussed, and options for a nuclear fuel will be presented.
1) Nuclear Reactors and Nuclear Fuel Functions, general safety and performance requirements.
2) Nuclear reactions, Slow and Fast neutrons, Effect of the minor actinides and fission products in nuclear fuel on to fuel properties. Multiplication Factor, Burnable absorbers
3) Depletion / Burn-up terminology.
4) Nuclear Fuel Materials:
Metallic Fuel (Uranium metal, Uranium alloys)
Ceramic Oxide Fuel (UO2)
Main properties, technology, meta-states.
Mixed Oxide Fuel (Mixture of Uranium and Plutonium oxides)
Uranium Carbide Fuel and Uranium Nitride Fuel
5) Fuel assembly Design. Fuel assembly materials (Zirconium Alloys).
6) Reactor control mechanism, options, problems (Materials of a control Rods, Soluble boron)
7) Known effects in the Oxide Fuel (radiation growth, swelling, form-shape transformation, fission gas migration inside uranium oxide fuel pellet, fuel thermal conductivity, pellet-cladding interaction, filler gas pressure effects).
8) Nuclear fuel failure mechanisms.
9) Current status of commercial reactors fuel.
10) Major challenges and areas for studies of the commercial reactor fuel
(Increase of fuel burnup, MOX fuel, New burnable absorbers, Fuel for Fast and High Temperature reactors).
11) Codes and methods for a fuel performance simulation (Presented by Anh Mai)
