I was listening to a podcast of Public Radio International from Canada where a specialist was explaining why newer plants have passive systems where electomagnets keep control rods from dropping into the reactor and why even newer plants have electromagnets keeping valves closed that could flood areas with coolant. All of these systems are activated by the absence of electricity.
It seems like such a simple idea, I wonder why noone thought of it 20-30 years ago when some of these older plants were built.
