![]() "Bill Daniels" bildan@comcast-dot-net wrote in message . .. I've slept on a nuclear powered Navy ship and felt very comfortable about it. I am an ex-Navy nuclear power plant operator, so I have also slept a night or two on a Navy nuke ship (submarine actually). I am not nearly as down on the civilian plants as you are. In ways, their operations are safer (or at least easier) than those the of the Navy because they tend to operate at a constant power for months at a time. They have (for example) no such thing as a fast scram recovery procedure, and, being attached firmly to the ground, don't have to deal with the pitch, roll and vibration of operating at sea. Furthermore, they use injected fission poisons so that they can operate with the rods pulled out, resulting in safer core power distributions and giving them a tremendous shutdown margin for emergencies. The Navy has the tradition of Adm. Rickover's obsession with safety. Yes, they do. The nuke Nave has roving squads of examiners that descend on ships without notice and, after a white glove inspection, will drill the crew beyond mercy. Failing an inspection can be a career-ending event, especially for the Captain, XO, and Engineering Officer. A publically held utility run by executives compensated with stock options just has too much incentive to cut costs. That is a concern, and not just for the nuclear power industry. We threw out some canned goods today that my wife found on the government recall list. Vaughn |

Cool, maybe you can answer my question. If one of the Navy Nukes were set up and run at a continuous power how much electricity could the plant provide. |

On a nuclear submarine the turbines that drive the generators are small compared to the turbines that drive the prop. Vaughn |

I've also heard that aircraft carriers are the ones that can really generate the electric power--and even there, the electric power is probably small compared to the porpeller drive power. Peter |

Peter I guess I could have asked my question better. How's this? How big of a generator (KW or MW per hour)could a nuclear reactor, such as one used on the newest generation of carrier, power. |

How big of a generator (KW or MW per hour)could a nuclear reactor, such as one used on the newest generation of carrier, power. I _think_ that the Gerald R Ford Class carriers are to be equipped with two (2) each 100 MWe reactors. The Perry, Ohio BWR reactor was planned to be about 350 MWE, if I recall correctly. USN reactor designs are quite different from civilian reactor designs for a number of reasons. In Particular, the former use more highly enriched-fuel to minimize their size. That is unnecessary for a baseline US utility, and also undesirable from a proliferation perspective. -- FF |

In ways, their operations are safer (or at least easier) than those the of the Navy because they tend to operate at a constant power for months at a time. It also seems that a lot of the executives and the operating personnel at US nuclear facilities are ex Navy bubbleheads as well. I believe the first Nuclear plant on the grid was a Navy sub that was connected to the Philadelphia grid and run for some time, but I can't find a reference for that now. Another factoid, the US Navy is the fifteenth largest utility in the US, although they buy most of their power rather than generate it themselves. Charles |
