Abstract
Passive Autocatalytic Recombiner (PAR) is of vital importance for hydrogen explosion prevention and mitigation at the nuclear power plants under severe accident conditions. From the early stage of PAR technology research and development in 1980-th the different types of recombiners have been proposed and tested at different scales. One of the mentioned recombiner type - namely self-intake PARs – now are widely used for hydrogen safety provision at the PWR, VVVR and CANDU nuclear power plants. Report goals are – 1) to briefly describe the history, motives for development of the different basic PAR types and their pros/cons for nuclear applications, 2) to argue - why the further PAR development can be valuable means outside of the nuclear applications, specifically, in the hydrogen energy and transport infrastructure safety? Joint (by engineering communities in the process industries and in the nuclear energy) development of the third generation of the inherently safe PARs and their appropriate technical standardization (in terms of performance and safety margins) by the international bodies can be valuable and effective step for global hydrogen energy and transport promotion and acceptance.
