Title: Nuclear reactor fuel-assembly duct-tube-to-handling-socket attachment system. [LMFBR]

Patent ·
OSTI ID:5558722

A reusable system is described for removably attaching the upper end of a nuclear reactor duct tube to the lower end of a nuclear reactor fuel assembly handling socket. A transition ring, fixed to the duct tube's upper end, has an interior-threaded section with a first locking hole segment. An adaptor ring, fixed to the handling socket's lower end has an outside-threaded section with a second locking hole segment. The inside and outside threaded sections match and can be joined so that the first and second locking hole segments can be aligned to form a locking hole. A locking ring, with a locking pin, slides over the adaptor ring so that the locking pin fits in the locking hole. A swage lock or a cantilever finger lock is formed from the locking cup collar to fit in a matching groove in the locking ring to prevent the locking ring's locking pin from backing out of the locking hole.
