摘要： PROBLEM TO BE SOLVED: To provide a neutron detector connection cable structure that securely functions as a neutron detector by preventing a short circuit between a core wire and a coating even if burrs are formed on a coating cut surface when the coating and an insulation material are cut leaving the core wire so as to interpose a ceramic terminal.SOLUTION: A neutron detector connection cable structure comprises a core wire, a coating covering the core wire, and a powdery insulation material interposed between the coating and core wire. For connecting an intermediate connection member by cutting the insulation material and coating leaving the core wire, the insulation material is raked from cut surfaces of the insulation material and coating leaving the coating, and a ceramic pipe is inserted into an insulation material part after raking the insulation material.

摘要： PROBLEM TO BE SOLVED: To provide a neutron detector support structure capable of securing smooth sliding of impurities by preventing the accumulation of the impurities while a furnace water smoothly flows in the gap (narrow part) between components even when impurities are contained in the furnace water.SOLUTION: An in-core detector guide pipe incorporates neutron detection for measuring a level of neutron flux in a reactor core by converting the level of neutron into an electric current. The outer pipe covers an outer peripheral wall of the in-core furnace detector guide pipe with a clearance left on the outer peripheral wall. A coil-like spring body is incorporated into the outer pipe and absorbs thermal expansion by winding on the outer peripheral wall of the in-core furnace detector guide pipe. A plunger is configured such that the lower end portion is located inside the outer pipe and supported by the spring body and an upper end head portion is elastically abutted against to a top guide which is a reactor core internal structure by the spring body. In the fitting portion between the plunger and the outer pipe, an outer pipe inner peripheral wall uses one end portion as a fitting portion fitted to the plunger, and the outer pipe inner peripheral wall except for this fitting portion is used as a furnace water circulation concave portion in which the furnace water circulates between the plunger and the outer pipe inner peripheral wall.
