Nuclear reactor safety

severe nuclear reactor accident that results in core damage from overheating

nuclear reactor component

substance with a large neutron absorption cross-section, which degrade nuclear fission chain reactions in reactors

reinforced steel or lead structure enclosing a nuclear reactor

lava-like material created in the core of a nuclear reactor during a meltdown accident

heat released as a result of radioactive decay

pressure vessel containing the nuclear reactor coolant, core shroud, and the reactor core

the change in the reactivity of a nuclear reactor when voids form in moderator or coolant fluids

set of subsystems that ensure security of a nuclear reactor (against technical failures) and minimize the damage during an incident or accident

mode of failure for a nuclear reactor

safety device in a nuclear reactor to contain the core in case of a meltdown
