The U.S. Navy has had tens of thousands of sailors living within feet of a nuclear reactor for over fifty years. None glow in the dark and as far as I know, we have never had a nuclear accident among them.

Cooling the reactor is the key to safety and reliability. The Navy reactors are surrounded by unlimited water but is must be desalinized and purified before use as a coolant so there is opportunity for failure however remote.

In terms of power availability, many years ago (30 or more?) a single U.S. submarine powered critical systems in the city of Manila by plugging into the grid after a natural disaster knocked out electrical power.
