  • Nuclear Reactor - Understanding how it works | Physics Elearnin video
    Nuclear reactors are the modern day devices extensively used for power generation as the traditional fossil fuels, like coal, are at the breach of extinction. A nuclear reactor is the source of intense heat which is in turn used for generation of power in nuclear power station. Its mechanism is similar to that of a furnace in a steam generator; the steam is used to drive the turbines of the electric generator system.
    A nuclear reactor consists of three crucial components: Fuel elements, moderator and control rods.
    Fuel elements come usually in the shape of thin rods of about 1cm in diameter and contain fissionable nuclei, like Uranium (235 92U or 238 92U). These rods vary in number according to the size of the reactor, in large power reactor thousands of fuel elements are placed close to each other. This region where these fuel elements are placed is called the reactor core. These fuel elements are normally immersed in water which acts as a moderator.
    The objective of a moderator is to slow down the energy neutrons in a nuclear reactor which are produced during the nuclear fission process by the fuel elements. Thermal neutrons, which are neutrons with energy of about 0.04 electron volts, are capable of producing fission reaction with 235 92U. During the fission reaction process, new neutrons are given out which have energies of about 1 MeV. These neutrons of typically escape from participating in another fission process as they are accompanied by enormous energy release. In f -ct, the probability of these neutrons produce another fission reaction is 500 times less than as compared to that of a thermal neutron. This is where moderator is extremely useful. Moderator has the capability to slow down, or in other words moderate, the speed of these high-energy neutrons, so that they can in turn be used for a chain reaction to trigger multiple fission reactions of other 235 92U nucleus.
    Commonly, ordinary or heavy water is used as moderator in nuclear reactors because of the deuterons present in them which are capable of slowing the neutron speed. Water molecules in the moderator are useful in slowing down the high-energy neutrons which leave the fuel-element after nuclear fission. These high-energy neutrons collide with water molecules thereby losing out on some energy with every collision and therefore slow down substantially. A new fission reaction can now be triggered using this slow neutron by striking it with the fuel element.
    The third and of the most prominent part of a nuclear reactor are the control rods. In order to get a steady output of energy from the nuclear reactor, every single nuclear fission reaction should trigger another fission reaction and ensure the availability of a spare neutron released to trigger the chain reaction. By controlling the number of spare neutrons available at any given time, the rate of the nuclear fission chain reaction can be controlled. This control on the fission reaction can be maintained using the control rods.
    The main function of the control rods is to absorb any excess or spare neutron in the moderator in order to prevent any further fission reaction. Usually such control rods are made of Boron or Cadmium. To increase the rate of fission reactions, these rods can be removed from the moderator. A steady output of energy can be thus maintained by inserting or removing the control rods in the nuclear reactor.
    Now that we know the components of a nuclear reactor, let us understand the working of a nuclear reactor. It is usually enclosed in a shield made of thick concrete walls. It consists of a reactor core, pump and heat exchanger. The reactor core and pump are in placed in contact with the water, which is usually the heat exchanger used in reactors. Due to the enormous amount of heat released dusing nuclear fission reaction, this surrounding water gets heated up and changes to steam, which is in turn used to turn the turbines. Thus huge heat energy gets converted into electrical energy. Water is continuously flown in and out of the nuclear reactor using the pump.
    Thus a nuclear reactor successfully generates nuclear energy from fission reaction.

    Thank you so much for this optimistic piece about nuclear power.
    I just wanted to add more about the positive effects.
    In the worst case scenarios of a massive earthquake and tidal wave with Fukushima no one died of radiation poisoning. But rather from the overreaction of the government not allowing people to return to their homes.
    A lot of people could have returned to their homes with very few mitigating factors.
    With Chernobyl, the RBMK reactors primary design was to create plutonium for nuclear weapons. Electricity was just a byproduct.
    The accident occurred because of the reckless ambitions of the lead engineer on duty. The deaths were created by the Soviet government not being upfront about the disaster.
    Just hundreds of feet away was reactor number three and then reactor number two and one. They kept running for about another 15 years.
    In both these scenarios today there is tourism including people that are walking right up to the reactor for a limited amount of time.
    Everyone knows that the news sells fear and anger. The news is part of the problem with keeping this truly green energy source from being deployed.
    There are forces that want to make nuclear power so expensive it can never be bilt. Principle among them are oil companies.
    The deaths and expense of global warming with its extreme weather is obvious and plays out everyday.
    I'm excited about generation 4 reactors. They're about six different designs and they have about six different characteristics.
    Some of the best characteristics are
    -They're considered walk away safe.
    -They burn more nuclear waste than they create.
    -The waste is considered hazardous for far less time.
    -They're non-proliferation so they can't be used for nuclear weapons.
    - The designs are small and can be as common as a hospital. They take up the footprint of about a Walmart. A truly local power grid to accompany wind and solar.
    This is truly the future that's going to power our electric cars and trucks. Some of the byproducts of nuclear power is creating hydrogen. This could power our airplanes, trains and ships.
    I look forward to clean skies without smog or inversion layers.
    I would much rather live next door to a nuclear power plant then a power plant admitting CO2 gas in other poisons and toxins.

      Indeed, many seem to believe that nuclear power creates a toxic environment but this is entirely untrue they produce very little waste and pose a very small threat as long as they are properly maintained and operated. Unfortunately some cities actually refuse to buy nuclear power and many have been shut down with no plans of reactivating instead they say solar is the future. Solar however creates much more waste than most realize and will most of it is recyclable it is not always recycled properly or at all.

A pressurizer to keep the water in the containment shell circuit liquid. This water would otherwise turn into steam. The next key element is a third circuit to cool the steam from the second circuit. And the last element is the condenser. The place where the steam from the second circuit (high and low pressure turbines) will collect and condense to water, with the help of the third circuit. Other from these 3 points good vid

      Hey hey, I know the answer to this one! There are rods in the core that absorb neutrons. These are called control rods. When the rods are at the bottom (fully inserted) they absorb enough neutron flux to prevent fission. To start the reactor, simply put, you slowly pull out the rods to specific heights and monitor power. Pulling too fast can cause something called prompt criticality

    • @paulanderson7796
      @paulanderson7796 Před 3 lety +11

      Fresh reactor fuel is pretty benign stuff, you can bare hand it perfectly safely. The chain reaction starts when you get a sufficient amount of fissile U235 in close proximity to each other and introduce a neutron source to 'light up' the reactor. Control rods are used to restrict the movement of free neutrons in order to maintain the required output from the reactor.

      The cooling water is not contaminated. This video is very simplified. In a nuclear plant, there are usually 3 circulations. The liquid which is heated by the reactor directly is contained, then the water that is indirectly heated into steam, turns the turbine, and converted from steam back into water, which is also a contained circuit. Finally, there is the water that cools the steam in a condenser, which comes from a water tower or nearby water source, which is never comes into direct contact with the radioactive liquid.

    Pretty accurate. Just so you know the neutrons interact with the hydrogen vin the water molecules because the hydrogen is the same mass as the neutron these allowing the neutron to give most of it's kinetic energy to the hydrogen I've been working in nuclear power for forty years of it's a pretty good explanation of how reactors create electricity those fast neutrons get absorbed by u238 if they don't escape the core first.

    The basic funda is almost same everywhere,i.e. the conversion of thermal energy into mechanical energy, which further converted into electrical energy by Dynamo.

      The geysers, which is properly called geothermal energy, uses steam turbines too. They don't just get it from the geyser, that would be too unreliable. They drill two very deep holes, push water into one, and steam comes from the other.

    In this model, the steam is recaptured, cooled to a liquid, and then pumped back into the main core reactor casing. Does this method increase the amount of radiation/fusion and energy production, or is it simply used to prevent radioactive water from being expelled into the atmosphere?

    • @OhKopo
      @OhKopo Před rokem +1

      first of, it is fission and not fusion, and it does not particularly increase energy production. Its advantage is the fact that, the water being heated indirectly, it is non-radioactive, meaning the steam going through the turbine is non radioactive. PWRs are the most common reactor type at the moment, because of simply how advanced and researched are its safety systems and its optimization aswell as containment. BWRs come next in term of spread of use, although the water is directly boiled in the BWR, so the steam is radioactive, but it does not mean it is dangerous at all.
