Evaluation of hydrogen recombination characteristics of a PAR using SPARC PAR experimental results

open access: yesNuclear Engineering and Technology, 2023
Passive auto-catalytic recombiners (PARs) are widely used to mitigate a hydrogen hazard. The first step to evaluate the hydrogen safety by PARs is to obtain qualified test data of the PARs for validation of their analytical model. SPARC PAR tests SP8 and
