Reactor vessel
Steam generators passive heat
removal system
is intended for implementation
of residual heat removal and reactor
shutdown cooling when there
is complete loss of power
or feedwater supply
Core catcher
is a cone shaped metal double
walled structure. Its function is
to retain liquid and solid corium
components in case of melt-
down accident and to maintain
the corium in sub-critical state,
preventing radioactive substances
from release
Containment passive heat
removal system
is intended to reduce and maintain
pressure within design limits inside
the containment during beyond design
basis accidents, including those accom-
panied by severe core damage
