Talk:Core meltdown

Question about the article. In it, it says: "During normal operation of a Light water reactor, meltdown is not possible...". My question is why is "Light" capitalized? It seems like it might be a proper noun (like a specific form of reactor), but then it seems like the whole phrase should be capitalized. And if it isn't a proper noun, then shouldn't "Light" be de-capitalized?--Just relax, and stay funny (talk) 21:23, 1 January 2013 (UTC)
