Deuterium Oxide?

post #1 of 4
Thread Starter 
(Heavy Water) What are the benefits of using Deuterium Oxide over regular water? If there are any. I thought of this like 5 minutes ago, and if it's good enough to cool nueclear reactors then its damn sure good enough to use in liquid cooling.

Any thoughts/ideas?

The only reason they were used in Nuclear Reactors was because it acted as a natural moderator for the free neutrons, replacing graphite moderators.

I assume that the only way it would help a loop is because of it's higher density, but the dangers and precautions necessary to implement it's use would be prohibitive. Anyways, most nuclear reactors use normal water now to cool the plant and they used enriched uranium.

Actually, there are no dangers to implement heavy water. It is completely stable. The only concern would be possible ingestion, as it can cause cell damage when present in high concentration in the body.

Heavy water will cool better, because it has a higher specific heat than light water (http://en.wikipedia.org/wiki/Heavy_water#Physical_properties_.28with_comparison_to_light_water.29). But the difference is minor, and it probably wouldn't be worth the extra cost.

That's what I meant. Should have been more clear. redface.gif
