abstract = {In Light-Water-Reactors a zirconium-steam reaction and
additional metal corrosion during heavy accidents with core
meltdown can result in massive hydrogen release. According
to a safety study conducted by GRS an existing
Boiling-Water-Reactors (BWR) and studies an future designs
for BWR, this may cause a pressure built-up in the
containment. As a consequence depressurisation of the
containment atmosphere is required. Experiments were
conducted basing an these studies to remove hydrogen from
the containment with regard to maintaining its integrity. In
a literature study conducted before oxidation of hydrogen
with manganese dioxide and separation by means of metal
membranes were found as methods with highest potential.
Their feasibility in varying accident environments was
shown. The oxidation reaction proved to be fast without
additional hazards. However, the high amount of oxidant
needed is disadventageous. The hydrogen removal by means of
metal membranes is slower than in case of the oxidation
reaction, but there is no limitation of a fixed amount of
hydrogen. Their potential for an application in reactor
containments is higher especially if the permeability of the
membranes can be augmented. Harmful, however, is the
hydrogen pressure difference needed for matter transport.},
