Stop stop stop! I have had no trouble saying nuc-le-ar for years...until now. I've read it so many times here that now I have to stop and think before I say it. So stop it I say! Lest you think it's not a word in everyday conversations - well you must not live within 10 miles of a Nuclear Power Plant, as I do - Seabrook Station- actually about 5 miles as the crow flies from my house, across the marsh to the plant.
Ya not gonna baleeve it BUT - at an NRC meeting I attended years ago as a reporter one of the Commissioners actually used The Other Pronunciation!
