N2 - Advancements in updating, improving, and extending of
fuel performance codes in use at VTT have been
accomplished. Continuing effort to introduce a
probabilistic transient analysis tool has resulted in a
concept of core-wide assessment that will be used to
estimate the number failing rods in an accident.
Steady-state codes have been further validated. Selected
models have been critically reviewed. In addition to
uranium dioxide, doped pellets, inert matrix fuel and
thorium dioxide fuel have been studied. Development
efforts at VTT are being combined with similar programmes
through international collaboration. Vital training of
young experts urgently required to compensate personnel
turnover has continued.
