Another one is >"Because it's a fast reactor, the HPM doesn't consume vast amounts of water, making it attractive for areas where water is scarce or unavailable." There's no reason a fast reactor should be different from an ordinary LWR in water use. A thermal power plant uses river or ocean water as a heat sink; nothing about a fast reactor changes the thermodynamic need for a heat engine to have a cold reservoir. Of course there's no longer water in the closed loop that cools the reactor core (which is what confuses them?).
