What safety features do reactors have to prevent overheating?
By Reactor I assume you mean a thermonuclear reactor. Most thermonuclear reactors use Boron rods to absorb radiation. This prevents the chain reaction in the reactor (where uranium nuclei split, each split nuclei further colliding and splitting more nuclei). They steam systems (that drive the turbines) are usually heated by gas or water. That is what the big towers are - cooling towers. The water is pumped to the top of the tower, and allowed to fall under gravity. this provides contact with the air and has a similar effect to sweating. If gas cooling is used, large radiators (like those on a fridge) use convection currents to move heat away from the reactor.
What is the name of India's first nuclear reactor?
India's First Nuclear Reactor was Apsara. It was also the first nuclear reactor in Asia. Apsara went critical at Bhabha Atomic Research Centre (BARC), Trombay on August 4, 1956. It heralded the arrival of India's nuclear energy programme. Dr. Homi Bhabha himself conceptualised the design of the reactor and the reactor was built entirely by Indian engineers in a record time of about 15 months.Apsara is a swimming-pool-type reactor loaded with enriched uranium as fuel. The fuel core is suspended from a movable trolley in a pool filled with water. The pool water serves as coolant, moderator and reflector, besides providing the shielding.
Can the waste of nuclear energy be reused?
some:The plutonium and other transuranics can be recycled. They make excellent reactor fuel.The unburned uranium can be recycled.Many of the fission products could be separated for industrial and medical uses.
How a nuclear power plant generates electricity?
A nuclear power plant generates electricity by turning turbines that turn generators. This is no different than fossil fueled plants. The difference in nuclear power is the source of the steam. Instead of a fossil fuel boiler, there is a nuclear reactor that uses the power of the release of binding energy (Strong Atomic Force) from the fissioning of (generally) Uranium-235. There are several designs. The two primary designs are the Boiling Water Reactor (BWR) and the Pressurized Water Reactor (PWR). The BWR forms steam in the reactor vessel which is transported to the turbines. The spent steam is condensed, reheated, treated, and returned to the reactor. The PWR forms heated water in the reactor vessel which generates steam in a separate steam generator (heat exchanger) which then is transported to the turbines. The rest of the cycle is similar to the BWR, but the return water goes to the steam generators instead of the reactor.
What are a completely mixed flow reactor and its concentration characterisrtics?
a completely mixed reactor. the concentration in the reactor is the same that flows our of the reactor
What type of energy requires a uranium and a reactor?
Nuclear energy, because uranium is a nuclear fuel for nuclear power reactors.
Why do you use uranium and plutonium in the reactor?
Uranium and plutonium can be used as nuclear fuels for nuclear reactors.
What is a use for Uranium fuel?
The use is to produce electricity from a nuclear reactor plant
Which elements are used for nuclear reactors in India?
Uranium. There is some interest in using thorium in the future. Thorium cannot be used directly as fuel in a reactor as it does not fission, it requires a fast breeder reactor to convert it to Uranium-233 which does fission.
In a breeder reactor a. Plutonium is converted into uranium or b. Uranium is converted into plutonium?
Uranium. A breeder reactor can use either Uranium, Plutonium, or mixed Transuranic elements for fuel. Depleted Uranium or Thorium is used as the breeding blanket. Periodically the breeding blanket is changed: the old one reprocessed to make new fuel.
Does CANDU reactor use enriched uranium?
CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.
How does weapon-grade uranium differ from nuclear-reactor-grade uranium?
Weapons grade uranium contains a substantially larger fraction of the radioactive isotope 235U than does reactor grade uranium.
How much uranium produces nuclear power?
The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.
Where does the isotope used in power plants come from?
Some of the isotopes occur in nature. For example, in nature there is Uranium 238, and Uranium 235, but only Uranium 235 can directly be used for a power plant (or for an atomic bomb). Uranium is collected, and the isotopes must then be separated. This requires some rather advanced technology.Sometimes isotopes are created at a reactor. Some material, perhaps Uranium 238, is kept close to the reactor, and while it absorbs neutrons, it changes to another element and isotope, one that can be used in a nuclear reactor.
