Abstract

See full text

The measurement device includes a means (18) for leaktight passage of a measurement conduit (20), produced in the form of a thimble, and an element (25) for connecting the end of the measurement conduit (20) to a smooth cylindrical extension element. The connection element (25) is produced in the form of a sleeve (26), the internal bore of which includes a first part (35) for receiving the measurement conduit (20) and a second part (36) for receiving the smooth cylindrical extension element. The connection element (25) includes, at the ends of the sleeve (26), a first removable means (28) for fastening and leaktight passage of the measurement conduit (20), and a second removable means (30) for fastening and leaktight passage of the smooth cylindrical extension element. The invention applies both to mobile-probe devices for measuring in the core of the reactor and to fixed-probe measurement devices.
