Re: Diesel-Electric Submarines vis-a-vis Nuclear

Robert:

The S5G reactor used on the USS NARWHAL (SSN-671) was a
natural circulatioon type, meaning that it used no noisy main coolant pumps.

The scoop seawater injection was used for cooling the main condenser for speeds over 5 to 7 knots. Not used for backing down or while stopped.

There was still a main condenser circulation pump for seawater
injection at slow speeds, etc. and its hull and backup seawater injection valves were motorized. I believe these were DC motors powered by the sub's battery, and so was the pump.

Many of today's non- nuclear surface ships, combatant and commercial, use the seawater scoop injection system to cool their main condensers.

I believe that the OHIO-cass "boomers" use this method also.

Hope this helps,

ROBERT M.
