specific Embodiment approach

[0014] Figure 4 shows a practical example of a multi-axis rotating gate. In experimental nuclear reactors, it is usually necessary to install several horizontal rotating channels in the shielding wall near the height of the core center. The key equipment of the horizontal rotating channels is the rotating gate. The overall size is about φ1000×1500-1800. Five turntables with different diameters are installed in the shell in turn, with the big head outside and the small head inside. The shell is a precision-machined cylindrical body with different diameters. Both ends are fixed by flat discs. A worm wheel hub is inserted on the outer side of one end of the large-end turntable, which is matched with the worm wheel, and a worm is installed in the casing. The worm is driven by the motor and the reducer to realize the rotation of the turntable. A total of 300 rotations. , One positive and one negative, to achieve the purpose of opening and closing.

Abstract

A multi-axle rotary gate for testing high-power high-flux nuclear reactor has 5 integral rotary disks. The main axle does not pass through the center. The small rollers outside rotary disks revolve along the intercal edge of shell. It can greatly increase the power of horizontal neutron channel to shield neutron and gamma ray.

Description

Technical field [0001] The invention belongs to the field of nuclear reactors, and particularly relates to a rotating gate used on a neutron channel of a test nuclear reactor. Background technique [0002] Rotary gates are usually installed in test nuclear reactors. The purpose is to draw out the thermal neutrons in the nuclear reactor to do a number of nuclear physics tests in the reactor hall. For the purpose of the test, it is required to increase the neutron flux and power of the nuclear test reactor. The revolving gate is to be able to extract the thermal neutrons in the reactor and apply it in the nuclear physics test. When the experiment is not done, it is required to be able to close the gate to shield the neutrons and gamma rays in the reactor from radiation to the reactor hall. The radiation dose inside is reduced to the prescribed standard. There are two structures in use in the existing turnstiles. One is the integral turnstile used in the JRR3 stack in Japan. Its str...
