Title: Fuse and application of said fuse to the construction of an emergency shutdown system for a nuclear reactor. [LMFBR]

Patent ·
OSTI ID:7140469

A fuse device for an automatic emergency shutdown system in fast reactors provides a coupling between a casing tube placed within a fuel can and a series of neutron-absorbing masses held together above the reactor core under normal operating conditions. They are released in free fall to the lower portion of the casing tube at the level of the reactor core as a result of melting of the fuse when operating characteristics such as temperature or neutron flux attain a level which exceeds a predetermined threshold.
