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 decrease thermal stress by biasing a slit position outwardly from a bottom plate center. CONSTITUTION:A control rod element 1 consists of a neutron absorber 11, an inner barrel 6 and an outer barrel 7 of a double cylinder vessel which houses the absorber 11, and an upper lid 16 and a bottom plate 8 which close the upper end thereof. A male screw is formed at an outer circumstance of the bottom plate 8, that is, at an outer side part of the plate 8, and the male screw is screwed into a female screw which is formed at an inner side of lower end part of the outer barrel 7. In this situation, each screw is placed at loosely engaging condition and thereby conbination gap thereof becomes a slit 9a of the bottom plate 8 and thermal stress can be diminished. In the case that rapid temperature change, that is, quick heating up of the outside of the element 1, occurs, the maximum thermal stress is generated at an upper inner part 10 of the bottom plate 8 due to inside and outside temperature difference in a distance d range between an outer surface of the outer barrel 7 and the slit 9a. In this occasion, the larger the inside and outside temperature difference in a distance d range is, the more the thermal stress at the upper part 10 is. Accordingly, by providing the slit 9a position at an outwardly eccentric position d, the distance d can be shortened and the thermal stress can be diminished due to reduced inside and outside temperature difference.

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.
