About

The Health & Safety Executive awarded a contract to Checkendon Hill Ltd for research support on the review of established good practices in the development of clad ballooning and embrittlement models for higher burnup PWR fuel.

The work involved collecting and analysing experimental data on ballooning behaviour and flow area blockage under LBLOCA refill, LBLOCA reflood, and SBLOCA boildown conditions, including consideration of the PAKS event and the influence of bundle size and radial constraint.

The contract also required identifying modelling methods and computer codes for predicting flow area blockage and heat transfer effects at 50–80 GWd/tU burnup, selecting three representative sets of methods and codes, estimating their accessibility and implementation costs, and providing conclusions and recommendations.

The contract value was AUD 23,300.
