I wonder if nuclear power plant safety analyses have considered magnetic storms and backup electrical power for reactors around the world.
I would bet they do not consider seismic events caused by strong magnetic storms coincident with the need for backup power during a world wide accident scenario. I hope continued operations of those backup systems use chips unaffected by strong magnetic fields. Magnetic shielding for those systems is probably a farce, given the uncertainty of conditions that may occur, for example, high shock and vibration mechanical loads, magnetic forces on ferro magnetic materials, the influence of water, etc., etc., etc. Fukushima considered a sumami and an earth quake as isolated (separate) events. Look what happened. Its like the FAA allowing continued operations of 737 max aircraft to operate in the US, somehow ignoring the fact that there has been TWO fatal chrashes of this type of aircraft in the last 6 months, both chashes having the same take off and nose down scenario. These design- basis- justified decisions, ignoring common sense failure modes, shows how fraudlent they are IMHO. Beware of stistical based risk assessment. The devil is in the details—the design basis assumptions.
