Research output: Chapter in Book/Report/Conference proceedingChapter or book articleProfessional


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.
