Abstract
Apparatus has a vessel fitting (2) and a retainer (10) that connect a core spray pipe system (4) to an opening (14) in a wall (8) in a vessel (9) in a boiling water nuclear reactor. The vessel fitting (2) has a plurality of resilient beams (76a), (766b), (76c), (76d), 76(e) and 76(f) arranged to extend into the opening (14) and lock the vessel fitting (2) in place on the vessel. The retainer (10) is installed on the vessel fitting (2) by inserting it through a passage (79) in the vessel fitting (2). The retainer (10) bears against the beams to maintain them in locking engagement with the vessel.
