Nuclear Reactors
Nuclear reactors are devices that maintain nuclear reactions. They are used in creating power and elements.

What is the name of the reaction that occurs in a nuclear reactors core?
The main reaction that occurs in a nuclear reactor core is nuclear fission. In this reaction, the nucleus of an atom is split into smaller parts, releasing large amounts of energy in the form of heat. This heat is then used to generate electricity in the reactor.
How is plutonium-239 produced in a breeder reactor?
Plutonium-239 is produced in a breeder reactor when uranium-238 absorbs a neutron and undergoes two beta decays to become plutonium-239. This process allows the breeder reactor to create more fissile material than it consumes, making it a sustainable source of nuclear fuel.
Why is nuclear power not considered commercially feasible?
plze tell me this ans..............................
Will thorium powered reactors be built?
Yes, thorium was used as a fertile material in nuclear reactors.
What step was taken to insure the nuclear reactor was safe in chernobyl?
The RBMK reactors at Chernobyl were probably the most unsafe reactors ever designed and built. They should never have been built.
What is reactor period in nuclear engineering?
Reactor period is the time is takes for a reactor's power to increase by a factor of e (2.71828).
Was Nuclear Reactors first invented to generate electricity?
No, nuclear reactors were not initially invented to generate electricity. The first nuclear reactor, known as Chicago Pile-1, was built in 1942 primarily for research purposes and to demonstrate the feasibility of a controlled nuclear chain reaction. It was part of the Manhattan Project, aimed at developing nuclear weapons during World War II. Electricity generation from nuclear reactors became a focus later, particularly in the 1950s, as the potential for using nuclear fission for power generation was recognized.
What are nuclear reactors made from?
Reactors are typically made from concrete,steel and lined with lead, the combination of these materials and built into a strong shape(bullet shaped or spherical shaped etc..) make up a nuclear reactor, these materials also absorb the radiation produced inside the nuclear reactor(lead absorbs gamma radiation and concrete absorbs neutron radiation).
Who invented the first nuclear reactor in India?
The nuclear reactor wasn't invented in India. Nuclear power was being researched in England, Germany, Austria, Russia and the USA during the 1930s and 1940s.
Idaho was the location of the first electricity generation using a nuclear reactor in 1951 with Russia operating the first to supply electricity to a grid.
India's entry to nuclear power generation followed many years after the intial development work has been completed.
How many deaths are due to nuclear reactors?
I'm not aware of any deaths which have been attributed to nuclear reactors in the US, Canada, or W Europe. What has happened in the past in the Soviet Union has never been fully admitted, but one suspects some accidents might have occurred especially in the early days. There were certainly well documented deaths in the Chernobyl accident in 1986 in the Ukraine. About 50 direct deaths occurred amongst the operating staff and firefighters. The more long term effects on the general population are difficult to assess and really one can only go on statistics. Website www.world-nuclear.org has some references which you can follow up if you want to get more information.
Additional Information:
SL-1 caused the death of three men. That was a US accident, the only one involving fatalities.
What does a transformer do in a nuclear reactor?
The same thing as in a fossil fueled or hydroelectric power plant.
A reactor jacket is a protective outer covering surrounding a reactor vessel or tank. It helps to regulate the temperature inside the reactor by providing insulation and allowing for temperature control through the circulation of heating or cooling fluids. This helps to maintain optimal conditions for chemical reactions or other processes taking place inside the reactor.
How big is the world's smallest nuclear reactor?
Bilibino Nuclear power plant in the Chukotka Autonomous Okrug, Russia, houses the world's smallest commercial nuclear reactor. It is equipped with four EGP-6 light water graphite reactors (LWGR) with gross power capacity of 12MWe each.
Here the world's 10 smallest commercial nuclear reactors, either in operation or under construction.
It depends on critical mass. For uranium-235, at normal density, at 100% enrichment, a perfect sphere would be critical mass at about 52 kg, or about 17 cm diameter. For plutonium-239, it would be about 10 kg, or about 9.9 cm diameter.
Problem is, that if you are right at critical mass, then the first event would take the reactor subcritical, because that first event would consume fuel, reducing mass, and reducing criticality. Its an interesting problem, and I can't get any more detailed than that, because information beyond this is classified, and I don't have access to it.
How many US nuclear reactors have been lost at sea?
some, also the navy deliberately sunk some because it was believed to be a safe disposal method at the time. exact counts are probably classified. Try a FOIA request or a MDR request.
