Nuclear reactor which produce delayed neutrons have half lives for their decay by neutron emission that range from milliseconds to as long as several minutes, and so considerable time is required to determine exactly when a reactor reaches the critical point. Keeping the reactor in the zone of chain-reactivity where delayed neutrons are "necessary" to achieve a critical mass state allows mechanical devices or human operators to control a chain reaction in "real time"; otherwise the time between achievement of criticality and nuclear meltdown as a result of an exponential power surge from the normal nuclear chain reaction, would be too short
Treaty on the Non-Proliferation of Nuclear Weapons Bush administration, although the latter disagreed to participate. The nuclear reactor was destroyed in the attack, which also killed about ten North Korean workers. The attack didn't cause an international outcry or any serious Syrian retaliatory moves as both parties tried to keep it secret: Despite a half century state of war declared by surrounding states Israel didn't want publicity as regards its breach of the ceasefire while Syria wasn't willing to acknowledge its clandestine nuclear program. Article X allows a state to leave the treaty if "extraordinary events, related to the subject matter of this Treaty, have jeopardized the
