That approach might make it harder to release steam from the reactors as part of the "feed-and-bleed" process that was being used to cool them, but that was a risk worth taking, he said.

Steam catapults aren't good for launching small aircraft like unmanned drones that are rapidly taking up a larger share of the military's aerial Arsenal.

Taking a heat-supply system in Jinan City for investigated subject, the heat loss rate of steam heat-supply network and hot water heat-supply network is analyzed and calculated.
