Pipe for supporting and positioning measuring devices in the core of a nuclear reactor

Image Number 4 for United States Patent #4917853.

The outer tubular shroud (14) of the measuring pipe (10) comprises a plurality of internally machined spacers (30), each intended to receive a set of measuring devices (32). The spacers (30) are connected by successive lengths of flexible tubing. The outer shroud (14) is open at its end part which emerges into the reactor core and comprises openings (27) in its side wall. This shroud is thus placed under equal pressure and the measuring devices (32) are in direct contact with the reactor coolant fluid.
