What type of reactor produces more radioactive fuel enough to fuel an additional reactor about every 7-10 years?
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.
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.
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).
What makes a radioactive chain end?
The final product is not radioactive.
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.
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.
What are the health hazards of the nuclear reactor?
A nuclear reactor emits radiation. In a PWR reactor, if the reactor temprature is around 650 Degrees, The emission near the reactor core is 2.57 Roentgen. That is the amount of radiation a human is exposed to in around 20 Years. There is also the dust, This dust if inhaled will cause cancer. If a Nuclear Powerplant explodes the story is different. Lets take chernobyl NPP for instance. The vincinity of the reacter core after explosion was 30,000 Roentgens per hour. That is 300 Sieverts per hour. That is enough to kill a man in 20 seconds. The fuel fragments that were realeased outward from the explosion the reactor had 15,000-20,000 Roentgens Pewr hour, And these fragments were laying on the ground after the explosion. Enough to kill a man in 30 seconds.
Is the coolant of a nuclear reactor dangerous?
For water reactors the danger would be mainly from the high temperature, escaping water would flash to steam and scald anyone nearby. CO2 cooled reactors would also present high temperature and risk of asphyxiation. There might be some radioactivity, but not a huge amount as failed fuel would have been removed before it became high enough to be dangerous. Of course if a Loss of Coolant (LOCA) occurred resulting in fuel failure, there might be more activity released, but design is aimed at preventing a LOCA, even in extreme cases such as an earthquake.
What are the main reasons why fusion reactions are not used in nuclear reactors?
No design of a fusion reactor has yet been able to reach what is called breakeven: the ability to make as much energy as it takes to operate the reactor. Until a prototype fusion reactor can make enough energy to operate itself, it is useless to even consider the uses of fusion reactions in possible power plants of the future.The temperature of a fusion reaction is not only high enough to melt any matter it touches but to vaporize that matter into a plasma! Therefore the reacting materials and their products must be confined in the reactor using forcefields not matter. We do not yet know how to make strong enough forcefields reliably.
what additional information would be enough to prove that SAY?
GIN
