Ok. That makes sense.
Do they use the diesel for anything other than auxillary power if the reactor is down? I assume you would have to be on the surface to vent the exhaust so it would be for a really extreme situation? |
Whenever we would rig ship for reduced electrical we would always snorkel. Definitely is done if the reactor scrams. Often times it is done until shore power is connected when pierside. The diesel engine produces enough back pressure to run at snorkel depth. The snorkel must must be raised in order to accomplish this while being submerged. |
Thanks for the info.
