The safety concept is taking advantage from the intrinsic safety characteristics of integral reactor and pursuing passive safety principles common to most small and medium reactors. The fundamental safety characteristics are:

— Low ratio of power density to heat capacity resulting in a slow rise of fuel element temperature under accident conditions;

— A substantially negative moderator temperature coefficient resulting from no soluble boron usage generates beneficial effects on self-stabilization and limitation of reactor power;

— Integral Reactor Vessel eliminates large primary coolant pipes and thus large break loss of coolant accidents;

— Large Passive pressurizer significantly reduces pressure increase for decreased heat removal events;

— Large volume of primary coolant provides more thermal inertia and makes plant more forgiving;

— No RCP seals eliminates potential for seal failures, a concern during station blackout;

— The use of passive safety systems leads to directly to simplification in design since it eliminates the need for multiple redundant safety systems with their redundant safety grade power supplies.
