To operate yes... but to keep safe when the grid goes out? Only NPPs require a permanent grid connection to not blow up. That is the key issue with the Zaporizhzhia NPP - it has been shut down for months, but still the rods need to be cooled, and it's a massive logistical challenge and an absurd amount of risk involved in keeping the grid connection alive and the backup generators supplied with diesel fuel.

This is untrue, and in the next sentence you contradict this statement when you mention the backup to the power grid: diesel generators which are substantially more portable, and less powerful than an entire energy grid.
