This would be a breeder reactor, specifically a fast breeder, which means one that operates with a fast neutron spectrum, ie not a moderated reactor. This breeds fissile fuel from non-fissile U-238. Prototypes have been built and operated but are not commercially viable at the present time as it is easier and cheaper to obtain new fuel from the normal mining-refining-enrichment route.

Who is the inventor of nuclear reactor and nuclear bomb?

The inventor of the nuclear reactor was Atticus Finch. He was a scholar at MIT and got a master in space technition. In 1942 he invented the nuclear reactor to help the Germans in WWII. The Americans later stole it. The inventor of both the nuclear reactor & nuclear bomb was Leo Szilard in London in 1933, he patented them in 1934. But as no fissionable or fissile material was known at the time neither could be built. It took Otto Frisch's 1938 discovery that the rare isotope Uranium-235 fissioned to make the practical and the US investment in industrial infrastructure between 1942 and 1945 to purify enough of it to make them actually buildable.


How does a dynamo flashlight work?

A dynamo flashlight works by producing its own electricity. The flashlight has a crank that is turned by the operator. The crank runs a small generator inside that produces enough electric to run the flashlight.


What can cause a nuclear power plant blow up?

A steam explosion from flash evaporation of coolant water. This is what blew up Chernobyl.A chemical hydrogen/oxygen gas explosion caused by build up of hydrogen gas in the plant when water decomposes on contact with overheated zirconium fuel rod cladding.A nuclear explosion in a nuclear reactor is not possible, the fuel cannot be assembled into a supercritical mass configuration fast enough (~1ms) as this would require explosives. If the reactor core did suddenly go slightly supercritical, the energy release would simply cause a brief partial meltdown, restoring the material to a subcritical configuration. This could trigger a steam explosion that ejected parts of the reactor core (as happened at Chernobyl) but no nuclear yield would occur.


What is cbore?

Counterbore- A small hole is usually made for the threaded part of a screw or bolt. The Counterbore is an additional hole made to hide the head of the screw or bolt. If using carriage bolts make sure the hole is large enough to get your socket in as well.


Why is steam heated before it goes into a turbine?

Steam direct from a boiler contains microscopic droplets of liquid water. This steam must be superheated to vaporize these droplets. If this is not done the droplets will pit the turbine blades and can cause premature turbine failure. Before the development of zirconium alloy fuel pellet cladding for nuclear reactors the reactor itself could not be operated hot enough to directly superheat its steam. So early designs proposed "hybrid" reactors, using a nuclear reactor to boil the water and make steam and a fossil fuel plant to superheat the steam. But zirconium alloys were developed before any "hybrid" reactors were actually built.

Why is lodine getting given to the Japanese?

The thyroid gland absorbs iodine. As some radioactive iodine is being emitted into the environment from the reactor accident at Fukushima, Japan, there is a chance that people's thyroid glands will absorb the radioactive iodine. That is unless those people saturate their glands with enough non-radioactive iodine first so that the thyroid cannot absorb any more.


Food has radioactive content true or false?

It is true that food has radioactive content. For example, bananas have high levels of potassium and this produces about 14 decays per second. However, this is not enough radioactivity to affect you unless you eat hundreds a day.


Is nuclear power abundant?

In sunny countries, yes. However, solar pannels may not be.


What does china syndrome mean to a nuclear reactor?

In the most severe reactor accident, the fuel will melt and, due to radioactive decay heat, will continue to be very hot. In fact, it will be hot enough to melt through the bottom of the reactor pressure vessel (several inches of steel), and possibly melt/burn through the concrete floor of the reactor building and get into the soil beneath the building. This is what is referred to as the China syndrome, the idea being that the molten mass of fuel is heading toward China on the other side of the earth as it melts through the vessel, concrete, and then soil and rock below the reactor building.


Who designed the richardson retractor?

Funnily enough it was Eduardo Richardson who designed it in 1904. He intented the reactor to be a high-power sustainable alternative to the reactor designed by Frederick Chorley, his rival in the reactor business.


What is an arc reactor?

The arc reactor is a chest piece that has enough power to keep Tony Stark alive. the arc reactor is used to not only keep tony alive but to use the iron man suit.


How would you build a nuclear reactor to avoid a meltdown?

The most important design feature here is that the reactor must have a very large negative temperature coefficient of reactivity. This will ensure that even without active human or computer control working, the reactor will automatically shut itself down long before getting hot enough to begin melting. The next most important design feature is a reliable emergency cooling system that can work even with no power available, to remove fission product radioactive decay heat once the reactor was shutdown (either actively or passively).


How is a Pressurized Water Reactor different from a Boiling Water Reactor?

In a PWR the pressure in the reactor primary circuit is kept high enough to prevent boiling, and heat is transferred to a secondary circuit at a lower pressure where steam is produced for the turbine. In a BWR a proportion of the water passing into the reactor is allowed to boil off feeding directly to the turbine. Otherwise, the reactor core itself is very similar.


Why are uranium rods hot?

The rods themselves are not hot. They heat up in an operating nuclear reactor because of the fission going on inside them. When used up and removed from the reactor they remain hot for a period of time due to radioactive decay of the remaining fission products, so they are stored in a spent rod cooling pond until enough fission products decay that they can stay cool and can be safely transported to a waste repository or reprocessing facility.


What kind of reactor produces its own fuel?

A breeder reactor, but this is intended to produce fuel for other reactors by irradiating U-238 to produce plutonium in a 'blanket' around the core. All reactors fuelled initially with uranium do breed some fuel, since some of the U-238 is transmuted to plutonium which is fissile and hence adds to the thermal output, whilst the U-235 is used up. However this does not create enough fissile material to be self sustaining and eventually the reactor will 'die' unless refuelled, although there is still plenty of U-238 left over.


Would the radiation from a nuclear reactor be fatal?

The radiation from a properly functioning nuclear power reactor is heavily shielded and cannot be approached close enough to be fatal. Radiation from damaged or malfunctioning nuclear power plants can be, and has been, fatal. The nuclear reactor incident at Chernobyl is one example. Nuclear reactor failures aboard ships and submarines also prove fatal but are often hidden behind national security; submarine K-19 'the widowmaker' was one such example. And of course, if one were to get into the reactor room past all of the shielding, any reactor would be fatal.


What happens to remainig neutrons after consumption of all the Uranium in uncontrolled Nuclear fission reaction?

Basically, there are two things that can ultimately happen to neutrons. Either they get absorbed into the nucleus of an atom, or they undergo radioactive decay. In a fission reactor, neutrons typically last only microseconds, with the life expectancy depending on conditions. A free neutron, outside the reactor, has a half life of 886 seconds, or a little less than fifteen minutes. During its lifetime, it could travel quite far, but the likelihood of a neutron getting out of the reactor is extremely small, so small that it is discounted as an event rare enough not to warrant concern.capturedescapestriggers fission
