Abstract

PURPOSE: To prevent from the contact of neutron measuring tube to the fuel assembly by the vibration of core flow, by means of so installing the widths of middle supporting rings which are positioned near at the supporting plate of the core of a neutron measuring tube as that the inherent frequency of the neutron measuring tube may become enlarged.
CONSTITUTION: A middle supporting ring 21 is set up near at a core supporting plate positioned location in a neutron measuring tube 20, a middle supporting ring 9' is set up at the location corresponding to the middle supporting ring, and sub- middle supporting rings 22, 23 are set up at both sides of the middle supporting ring 9'. The inherent frequency of the measuring tube 20 becomes high by making the width of the middle supporting ring 21 beyond the double (namely 30 mm.) compared with that of the conventional ring. A TIP tube 25 into which is inserted by an outer tube 24 of the measuring tube 20, is composed of a tube body 26 and a plurality of reinhold plates 27 (may be waved thin plates) fixed at the outer circumferent surface
