> Steven,  you asked about reactors and cold weather.  I recall several years ago I was at a mid-winter Emergency Preparedness seminar (coincidentally) when a call came in that a midwest nuclear plant declared a Site Area Emergency (I think) due to the freezing of an essential cooling reservoir.  If I remember, the plant had trouble drawing water due to ice buildup at the intake.  They worked through the problem in a few hours and got out of the emergency but I suppose they might have begun a downpower if they were unable to provide adequate cooling.  All commercial nuclear plants are designed to either operate or safely shutdown with whatever their particular extreme conditions are - hurricanes, tornados, earthquakes, freezing, etc.  For example, Florida plants have either operated through or shutdown in advance of hurricanes and then started back up after evaluation proved there was no damage to equipment important to safety.  The joke out here in California is that if the "big one" ever hits, the nuclear plants will be ready to provide power but there won't be anything left standing to send the power to.
