This is welcome news. it means that all the necessary agencies are thinking about the risk and planing risk abatement. I posted on this problem several years ago when there was zero awareness at any level and have tracked a slowly enlarging pool of awareness.
Humanity will never be fully protected until we build sub surface Refugio world wide and that should be our real objective. It combines nicely with the protocols that end poverty and also Terra form the planet generally.
In the meantime we need to actually harden our whole electrical and electronic infrastructure. This is technically difficult enough but not actually impossible as a Faraday cage nails most of it. Even conductive dust in our plastics may be an option. you get the idea.
This also protects us against an actual nuclear blast as well which will produce an EMP event...
