n traditional power engineering hydrogenmay be one of the
first primary source of equipment damage. This problem
has high actuality for both nuclear and thermonuclear power
engineering. Study of radiation hydrogen embrittlement of
the steel raises the question concerning the unknown source
of hydrogen in reactors. Later unexpectedly high hydrogen
concentrations were detected in irradiated graphite. So,
alloying of steel and graphite by hydrogen in nuclear
reactor takes place. It is necessary to look for this source of
hydrogen especially because hydrogen flakes were detected
in reactor vessels of Belgian NPPs. As a possible initial
hypothesis about the enigmatical source of hydrogen one
can propose protons generation during beta-decay of free
neutrons in as much as protons detected by researchers at
nuclear reactors as witness of beta-decay of free neutrons.
