Either way it's done, a nuclear plant is a large, centralized power source, and having it be taken out while heavily relying on the power it supplies to the grid might not be all that great, not to mention the economical issues with fixing mirrions of dorras worth of equipment that is bound to be damaged should some meanie get their hands on the controls.
