In general, nuclear reactors are devices that use mass-depletion energy resulting from fission reactions. Unlike thermal furnaces in which combustion is automatically expanded by combustion heat, nuclear reactors perform nuclear fission reactions through neutrons released during nuclear fission of fuel.

Nuclear fission reactions in a nuclear reactor can control the combustion of nuclear fuel by controlling the number of neutrons absorbed by the fuel.In order to continue nuclear fission in a nuclear reactor, at least one of the neutrons released during nuclear fission is absorbed by the fuel again to cause nuclear fission again. do. If the number is 1, the fission reaction remains constant, neither decreasing nor increasing, and this state is called the criticality of the reactor. In addition, when the number exceeds 1, the number of fission reactions is gradually increased, which is called a supercritical state, and vice versa.

In general, when operating a reactor at a constant output, it is used to absorb the extra neutrons in the control rod by putting it in a critical state or slightly over the critical state. The average number of neutrons released in a single fission is about two in the case of uranium 235, but not all of them contribute to nuclear fission again, and their numbers decrease due to leakage to the outside of the reactor or absorption into non-fissile materials. It is important to minimize these neutron losses in order to continue driving. To prevent neutron loss, increase the amount of fissile material or decelerate high-speed neutrons released during nuclear fission to thermal neutron level to increase absorption probability, and minimize leakage to the outside of the core. The size of the reactor is large enough to be able to do so, and the method of minimizing the absorption of other non-fissile materials is possible. Neutrons emitted at the moment of nuclear fission are high-energy fast neutrons, and the probability of being absorbed by nuclear fuel is extremely low. Therefore, it is important to reduce them to increase the absorption probability. The control of the reactor is controlled by adjusting the number of neutrons by inserting or removing a material having a large neutron absorption cross-section such as cadmium boron into the core, and also using a method of changing the amount of reflector or moderator.

An example of connecting and lifting 130 by the wire 240 is shown. The wire 240 may be a wire rope. Wire rope is a wire rope made of twisted steel wires. It is used throughout ships and various machines, and especially in transportation and unloading operations. It can be produced by twisting a wire of about 1 to 3 mm in diameter, which is usually elongated using hard steel wire as a raw material. A commonly used wire rope is a strand rope made by twisting strands of wire around a seam again. In addition, spiral ropes are made by twisting strands of wire in parallel to the required cross-sectional area so that the cross-section is concentric. In this case, a relatively thick wire is used. Rock coil rope, a kind of spiral rope, is a wire rope of other cross-sectional shape such as square or Z shape on the outside to reduce the gap of the rope. It has the advantages of smooth surface, less wear and water tightness, but it is not flexible. There are also disadvantages. In addition, there are cable raid ropes formed by recombining the stranded ropes, and flat ropes in which the stranded ropes are woven in a belt shape. Twisting the wire is a Z twist or S twist, usually Z twist is used a lot. However, when making ropes with multiple wires, wire ropes that combine Z and S twists may be formed to alleviate the torsional effects of the rope.
