This has always been one of my biggest pet peeves regarding the pronunciation of this word. It's so simple. Nu = New Clear = clee-r . Not much of a stretch as Nuc = Nuke lear = you-lar. Please note that I am usually forgiving of most infractions of the English language, but there are a handful of them, including this one, that just drives me nuts. Especially when they are simple one or two syllable words.
BTW, library, February, and the misuse of the word all's, are among the list. Do you know how many people who I encounter that constantly say "All's I know is that blah...blah...blah" It makes me wonder how they made it through school. Or does the blame lie there, with the educational institutions?
Still wondering....

P.S. Some people take the opposite stance when it comes to "all's". They state that there is no such word. Rubbish! Shakespeare used it properly when he wrote: "All's well that ends well." It's just a contraction for all is. <Rant mode off>
