Rotor Cascade Assessment at Off-Design Condition: An Aerodynamic Investigation on Platform Cooling
International Journal of Turbomachinery, Propulsion and Power, 2023 Off-design condition of a rotor blade cascade with and without platform cooling was experimentally investigated. The ability of the gas turbine to operate down to 50% to 20% of its nominal intake air flow rate has an important consequence in the change ...

Analysis of Loss-of-Coolant Accidents in the NBSR [PDF]
, 2014 This report documents calculations of the fuel cladding temperature during loss-of-coolant accidents in the NBSR. The probability of a pipe failure is small and procedures exist to minimize the loss of water and assure emergency cooling water flows into the reactor core during such an event.
