FIELD: recombination off hydrogen and/or carbon monoxide by oxygen for nuclear power stations.
SUBSTANCE: catalytic element (1) has body (2) with catalytic surface (4). Measures are taken for reliable avoidance of spontaneous ignition of gas mixture. Catalyst is provided with throttling layer (10,10A-10D) applied on catalytic surface (4) or on catalyst body (2) for deceleration of diffusion of reaction gases.
EFFECT: enhanced reliability of excluding ignition of gas mixture in protective shell of nuclear station.
