revision appliestonly to an optional configuration of item 16 (wedge).and is shcwn as ltem 32 (option 10). The wedge head of the lid retaining block'has.
been shortened but will still cover.both metal-to-metal' stops in the yJid seat
-j area and thus will prevent lid motion.- The purpose of this revision is;to' facilitate the installation of the wedge.by r' emote operat; ton sin order to reduce i
the radiation exposure to persconel. >
