title: Dihydrogen gas emission of a 250kW(th) research reactor.
abstract: The Vienna TRIGA pool-type reactor emits tiny gas bubbles at 250kW. They add up to a total volume of ∼2.4L in 7h of daily operation. The bubbles consist of nitrogen (72.5vol%), hydrogen (17.2%), oxygen plus argon (12.0%) and carbon dioxide (0.23%). The emission of constituents of air is caused by degassing of dissolved air in the hot regions of the reactor. Hydrogen results from neutron-induced radiolysis of the cooling water. This emission should be kept in mind for reasons of fire protection even for low-power reactors.
