| titleOfInvention | Uniform guide tube with bleed hole retractable switch |
| abstract | The present invention relates to a guide tube, and more particularly, to a guide tube constituting the skeleton of the nuclear fuel assembly and absorbing the impact when the control rod falls.n n n The present invention includes a guide tube and the shock absorbing tube.n n n The guide tube is formed in a hollow hollow cylindrical shape of the inner and outer diameters throughout, and the cooling hole and the bleed hole are formed on the outer circumferential surface of each of the upper and lower sides in the longitudinal direction.n n n In addition, the shock absorbing tube is formed in a hollow cylindrical shape having an outer diameter that can be inserted into the guide tube with a small play, a cantilever-shaped switch moving in the transverse direction is formed by cutting one end portion is inserted into the guide tube, When the control rod is inserted during operation of the reactor, the switch blocks the bleed hole of the guide tube due to internal pressure, thereby delaying the falling speed of the control rod.n n n As described above, the present invention is provided with a shock absorbing unit separately to eliminate the possibility of heat deformation and local material changes that may occur by coupling to the guide tube by welding, to ensure structural stability.n n n In addition, the inner and outer diameters of the guide tube and the shock absorbing tube are uniform, which not only simplifies the manufacturing process but also increases the stiffness in the lateral direction by eliminating secondary moments and cross-sectional area changes.
