摘要： The invention relates to nuclear technology, and specifically to systems for controlling and protecting nuclear reactors. A drive of an emergency safety rod of a nuclear reactor includes an electric drive, a reduction gear, and a rack-and-pinion gear. The electric drive contains a contactless electric motor based on permanent magnets, which is installed in the housing of the electric drive with a motor rotor position sensor, and a reduction gear for changing the rate of rotation of the electric drive. A toothed rack is installed along the axis of the rack-and-pinion gear in order to provide for the reciprocating motion of a system absorber rod connected thereto. A toothed electromagnetic clutch having a contactless current supply is installed on an inner shaft of the rack-and-pinion gear, enabling the rigid and simultaneous mechanical coupling of half-couplings, and the drive contains a reverse motion coupling, a rack-separation spring and toothed rack position sensors. The invention makes it possible to reduce the time necessary for adding negative reactivity to a nuclear reactor core.

摘要： The bayonet plate of the bayonet plate closure between control rod guide tube (1) and drive housing pipe (2) of a boiling water reactor is designed in two parts. It comprises a central bayonet ring (6) mounted rotatably about its longitudinal axis (3) with an outer ring (7) completely surrounding said bayonet ring. The outer ring (7) is mounted on the circumference of the bayonet ring (6) and reaches inwards under the bayonet ring circumference. Said ring is furthermore permanently supported in the axial direction on the drive housing pipe (2) by the spring pressure acting on the control rod guide tube (1), in order to produce a frictional connection. This spring pressure can be released unhindered from the reactor side by tools.

摘要： A latch and linkage arrangement (112) in a nuclear reactor control rod drive mechanism (32) includes a latch (114) having an elongated body (118) with opposite ends (118A,118B) and opposite side edges (118C,118D) and multiple latch teeth (116) defined along one of body side edges between the opposite ends. The arrangement also includes a plurality of links (126,128,130). A first link (126) pivotally connects with the latch body (118) adjacent one end (118A) and is pivotally connected to an electromagnetic armature (86,88) for applying a motive force to the latch body (118) through the first link (126). Second and third links (128,130) are pivotally connected to the latch body (118) and to a support tube (58) in parallel relationship to one another so as to define a parallelogram therewith such that when the motive force is applied to the body (118) via the first link (126) the latch body (118) and thereby the latch teeth (116) undergo curvilinear movement toward and away from a latching position.
