Equipped with inflatable seals, these gates are designed to ensure bubble-tight sealing, even in large sizes. They are a proven design, used successfully in several installations. Depending on the requirements, gates can be supplied with single or double seals, or as a two gate assembly with a monitoring chamber between the gates.

QualTech NP fuel pool gates are furnished in either hinged or lift-out style, complete with matching frame. Installation requires only welding of the frame to the spent fuel pool liner.
