About

The Health & Safety Executive awarded a contract to Checkendon Hill Ltd for research support on the study of local heat transfer co-efficient on peripheral PWR assembly fuel in the event of touching spacer grids.

The work involved identifying base phenomena defining the CHF limit for flow reduction and overpower fault conditions in the PWR core, considering the potential for TSG and the limitations of CHF test rigs in representing core cross-flow and assembly-periphery conditions.

It included reviewing options for CHF prediction and their development status across leading PWR vendors, operators, fuel providers, and independent research establishments, and recommending a strategy for ONR to assess the adequacy of safety margins in set points for CHF mitigation arrangements.

The contract value was AUD 26,650.
