Burnup Measurement using Bent Crystal Diffraction Spectrometers for Pebble Bed Reactors
Ian Kolaja, Lee Bernstein, Ludovic Jantzen +3
Burnup measurement is essential for monitoring and controlling pebble bed reactors (PBRs), where fuel pebbles circulate rapidly through the core. However, conventional gamma spectr…

Predicting and forecasting reactivity and flux using long short-term memory models in pebble bed reactors during run-in
Ian Kolaja, Ludovic Jantzen, Tatiana Siaraferas +1
Pebble bed reactor (PBR) operation presents unique advantages and challenges due to the ability to continuously change the fuel mixture and excess reactivity. Each operation parame…
