摘要： PROBLEM TO BE SOLVED: To provide a reflector controlling reactor of which the neutron reflector can smoothly move up and down in a moving region.
SOLUTION: A projection part 22 extending in horizontal direction along side 21a and 21b of the neutron reflector 21 moving up and down inside the moving region 8 is projected and a coolant flow path 23 between the inner wall of the moving region 8 and the neutron reflector 21 is narrowed. As fluid force such as fluid resistance, fluid pressure and viscosity force strongly work, the neutron reflector 21 smoothly moves up and down in the moving region 8 without vibrating to up and down direction, back and forth direction and left and right direction. Also, since the inclination of the neutron reflector 21 inside the moving region 8 can be made small, the neutron reflector 21 does not catch on the inner wall of the moving region 8 when guided by a slide on the end surface 22a of the projection part 22 and the inner wall surface, and can smoothly move up and down inside the moving region 8.

摘要翻译：要解决的问题：提供一种反射器控制电抗器，其中中子反射器可以在移动区域中上下平稳地移动。解决方案：在水平方向上延伸的中部反射体21的侧面21a和21b在移动区域8内上下移动的突出部分22突出，并且在移动区域8的内壁和中子反射体之间形成冷却剂流路23 21缩小。由于流体阻力，流体压力和粘度力等流体力强烈地作用，中子反射体21在移动区域8中平滑地上下移动，而不向上下方向，前后方向以及左右方向振动。此外，由于中子反射体21在移动区域8内的倾斜度可以较小，所以当由突出部分的端面22a上的滑块引导时，中子反射器21不会卡在移动区域8的内壁上 22和内壁面，能够平稳地在移动区域8内上下移动。

摘要： PROBLEM TO BE SOLVED: To provide a micromovement device capable of preventing reduction in moving characteristic resulted from the rigidity influence of a body to be driven even in an enlarged device such as fast reactor and ensuring a stable moving characteristic, and a reactor equipped with this device. SOLUTION: A movable body 3 moving along a guide wall 2 has a movable body main body 3a, an inertial body 5 movable in the moving direction of the movable body 3, a pair of electromagnetic repelling coils 6 and 7 for generating an instantaneous electromagnetic repelling force between the inertial body 5 and the movable body main body 3a, and electromagnets 11 and 12 for retaining the body to be driven 4 on the movable body main body 3a and attracting the inertial body 5 to the nearer or farther electromagnetic repelling coil 6 or 7. The inertial body 5 is made to selectively approach and moved to either one of the electromagnetic repelling coils 6 and 7 by the electromagnetic state change of the electromagnet 11 resulted from the presence or absence of the connecting state of the body to be driven 4 to the movable body 3, and an impact force is generated between the movable body main body 3a and the inertial body 4 by the electromagnetic repelling coil 6 or 7 to which the inertial body 5 is approached and moved to move the movable body 3.

摘要： PROBLEM TO BE SOLVED: To realize highly precise measurement excellent in reproducibility. SOLUTION: This device/method has a low-frequency superposed power source 4, a ZCT 7 having a secondary coil and a tertiary coil as a calibration signal input coil and attached to a cable way 1, and a calibration power source 12 for inputting a low-frequency of calibration current into the tertiary coil of the ZCT 7. The low-frequency of calibration current is input into the tertiary coil of the ZCT 7 by calibration measurement to find a gain Gcal (=¾Ig÷Ical¾) and a phase difference θcal (=Ig∠Lcal) as calibration information, and a zero phase current Ig acquired by the the ZCT 7 in the measurement is corrected using the calibration information to remove an influence of the phase shift in the ZCT 7.
