摘要： PURPOSE:To maintain the soundness of the control rod by coupling control rod elements by a spine at their center part, connecting the upper end of the spine to the titled device suspended by a wire rope, and providing a buffer mechanism between the wire rope and spine. CONSTITUTION:The control rod elements 1... are coupled by the spine 2 in a longitudinal axis direction and the upper end of the spine 2 is suspended by the wire rope 4 through a metallic coupler 3 and a spring 18. Then when a nuclear reactor is stopped urgently, the rope 4 is fed out to fall the elements 1... in a reactor core and the feeding of the rope 4 is stopped when the elements 1... reach a specific position. At this time, an impact force of about 5kg is applied to the rope 4, spine 2, etc., but reduced by the spring 18, so the safety of the nuclear reactor is increased.

摘要： PURPOSE:To improve the reliability and safety of a shock absorber by constituting the shock absorber of bellows and guide sleeves which slide in the elongation and contraction direction of the bellows. CONSTITUTION:The shock absorber 15 is constituted of the bellows 16a, 16b and the guide sleeves 17a to 17d which slide in the elongation and expansion direction of the bellows 16a, 16b. The shock absorber 15 collides against a reactor floor part and is thereby deformed if a wire rope 10 is broken and a control rod falls into a control rod insertion hole 5. The shock absorber 15 is constituted of the bellows 16a, 16b and the guide sleeves 17a to 17d in such a case, then the large deflection of the bellows 16a, 16b in the insertion hole 5 is prevented by the guide sleeves 17a to 17d. Even if, therefore, the control rod falls into the insertion hole 5 by the breakage accident of the wire rope 10, the arresting of the shock absorber 15 in the insertion hole 5 is obviated and the control rod can be pulled up from the hole 5.

摘要： PURPOSE:To enable shifted coupling of a control rod guide tube from a control rod insertion hole by forming a step between a control column upper neutron shielding body and a core column upper shielding body and making the upper end part of a control guide tube movable. CONSTITUTION:A stepped part 25 having a taper 26 is formed between a control rod column upper neutron shielding body 22 and a fuel column upper neutron shielding body 23. A fitting member 28 fitted in a hexagonal recess 27 formed by the stepped part 25 is provided to bundle a plurality of guide tubes 21 on the lower part of a control rod guide tube 21. A circular support plate 29 which also serves as a spacer is provided on the upper end of the guide tube 21. The support plate 29 is housed and held in a cylinder frame 30 provided on the lower part of a guide tube support member 24 and thereby the guide tube 21 is held movably upward and downward, horizontally. Thereby, even if there is a little shift between the axes of the guide tube 21 and the control rod insertion hole 20, they can be connected each other and excess stress doe snot occur in the guide tube 21.

摘要： PURPOSE:To prevent the degradation in the life of the control rods by an excess stress and plastic strain by integrally forming spacer pads having a regular polygonal shape on the outer peripheral surface of an outer cladding pipe by chipping the outer cladding pipe. CONSTITUTION:The spacer pads 11 constituting the regular polygonal shape for maintaining control rod elements 1 at the center of a control rod insertion hole are integrally formed on the outer peripheral surface of the outer cladding pipe 6 by chipping the outer cladding pipe 6. Although the control rods causes swelling (volumetric expansion) when subjected to the irradiation of high-flux neutrons in a reactor, the spacer pads 11 for maintaining the control rod elements 1 at the center of the control rod insertion hole are integrally formed to the outer cladding pipe 6 by chipping the pipe and, therefore, even if the control rods are subjected to the irradiation of the neutrons of the high flux, the generation of the stresses by a difference in the swelling rate in the periphery of the spacer pads 11 is obviated. Even if the control rods receive the severe heat excess of a large difference in temp., the material strength is stable and, therefore, the generation of the plastic strains in the periphery of the spacer pads 11 is obviated. The life of the control rods is, therefore, improved.
