If a designator is closed what they will often do is the program manager will reject it for that designator and it will never be sent to the board, or it will be held until a board for that designator is scheduled, it just depends on the directions the PM's have been given.
Not to burst bubbles on waivers but they are essentially rubber stamped, the fact it included Intel doesn't mean anything as NRC in nearly every case defers to the board on if they will actually accept the waiver or not. The boards are also limited in how many with waivers they accept, IWC has been one of those communities that in the past has been tough on TIS waivers due to past issues with their community health, so how far past the max TIS you have will be a factor.
