Just a question that came up at work, we have some theory to practice data but no real control. Is there any fact behind thermal inertia? Example a pot of hot water at 200F and a pot at 50F which will freeze first?
Hebron
Thermal inertia is another name for bulk heat capacityIn the formula:Q = m*c*deltaTthe m*c part is the "thermal inertia".Thermal inertia depends upon:1. mass of object of interest2. specific heat capacity of the material typeYour pots of water question HAS NOTHING TO DO with thermal inertia being part of the solution. AT no point do you mention the mass of water in each pot, which you PROBABLY SHOULD, or at least mention that they are identical pots with identical amounts of water. In your pot example, the simple thremodynamics answer is that the cold water "should" freeze faster. The reason being, is that the hot water will begin to cool, and eventually just get to the same condition as the cold water, such that the cold water actually had a "head start" on the hot water. EVEN THOUGH, the hot water would have an initially higher cooling rate, it still needs to catch up with the cold water before it can freeze. That is what would result if you were to model the water as a lumped system, as in, a body that always fully distributes all its temperature at any given instant in time, and a body that never looses or gains material. It is a simplification that makes transient heat transfer problems a hekka lot easier. That being said, like I said, the lumped systems analysis is a simplifying approximation. Reality however DOES NOT match these results. We give a name to this inconsistency, we call it the Mpemba Effect. http://en. wikipedia. org/wiki/Mpemba_effe…IF you read the article carefully, it says that "in certain specific circumstances, warmer water freezes faster than colder water".And it even specifies what those "certain specific circumstances" are. And in many cases, the experimental circumstances people attempt, happen to be those certain circumstances. It isn't always the case that hot water freezes faster than cold water...it just happens to be the case in many circumstances. In other circumstances, the result is the opposite.
Somerville
The pots are not quite a parallel with the reactor. The 200F pot has more heat energy in it so it will take some time to cool to 50 degrees. From that point it would take just as long to freeze as the other ( 50 degree ) pot. So it takes longer to freeze a 200 deg pot than a 50 degree pot. On the other hand there is more HEAT PER SECOND removed from the higher temperature pot so it is in fact cooling more quickly than the cooler pot. I have no idea of the term "thermal inertia" as inertia is a tendency to resist a change in movement.(See newtons laws for a description)I have never heard of this concept when applied to heat.

What happens if a nuclear reactor fails an inspection?
Landingville
WHat power does the IAEA have if the reactor fails the safety test?
Honolulu
The reactor is shut down, if there is danger, it is isolated, and then repaired.
Sunnyside
If the Reactor itself was to fail a portion of a safety test, that would be a problem with the engineering side, not the operation side. So the engineers would fix the problem. The IAEA and each countries individual Nuclear Regulatory Commission will set the standards for the safety test.
Bentleyville
They set off a big loud siren and everybody has to go home early.

A very good book for you might be "Nuclear Engineering, Theory and Technology of Commercial Nuclear Power", Second Edition, by Ronald Allen Knief. ISBN 978-0-89448-458-2That book covers all you would want to know about nuclear reactor types added to the rudiments you muscle poverty to from time to time reference plane if you were to make nuclear engineering a career. It covers basics as spectacularly as all the regulatory factors, fuels, safety, and even has a chapter on fusing. One could not ask relative a better overall nuclear activity criticism. I bought a copy a pair of months ago even however I beget been introduce the nuclear province for surrender 40 years mention all areas, besides serving as an inspector or consultant at BWRs and PWRs.

How do nuclear operators actually start a nuclear reactor how is the process started?
Bellerose Terrace
Nuclear Reactors, and the process used to levy them depreciating.
Mount Olympus
There is water/gas cooling heat exchanger are started first to avoid overheating. There is some checking for Hydrogen which can mean a water leak into the core. The 3mile island problem is online. It explains what the operators did to worsen the problem and what could have been done in detail. Try Am Institute of Physics, Physics Today site.
Ladd
The "Best Answer" doesn't answer the question on how the reactor gets started - that's just one part of the process. Report Abuse
Doffing
When fuel is loaded, all the control rods are down in the core to absorb excess neutrons and not let it go critical - to bring the power up they start removing the control rods to allow the chain reactions to start...
Drayton
To start a nuclear reactor the administrate rods are removed with an increment of the counteraction begins make over its admit. Because the recoil is extemporary, the control rods are a carping part and must prove false completely inserted any spell the reactor is not operating

What does nuclear moderation accomplish in a nuclear reactor?
Nashville
Chemistry.
Cottage City
A moderator is used to slow down neutrons. Some commonly used moderators are heavy water, light water(normal water) and graphite. The reason one might want to use a moderator is because sometimes by slowing down the neutrons they are more readily absorbed by the nuclei. For example, when neutrons are released from the splitting of Uranium-235 they are more readily absorbed by Uranium-238 than by other Uranium-235 nuclei however by slowing down the neutrons with a moderator, it allows the neutrons to be more readily absorbed by Uranium-235 to sustaining a chain reaction.
Garden City
I'm no nuclear physicist, so my understanding is rudimentary, but without moderation in the form of more/less fuel rods, water containment/cooling and rods used to absorb neutrons, the reaction could easily get out of control and lead to a melt down situation.

How are radioisotopes created in a nuclear reactor?
Molena
School assignment here... Well, I know that most of the radioisotopes (such as Americium-241: used in smoke detectors) are produced in a nuclear reactor through neutron salvo cognizant of Uranium-235 which times undergoes neutron capture and then beta decay added to so on and on. What I'm loooking for is just more correct details of what actually happens in the reactor when neutron bombardment happens and how the isotopes are extracted. Any info would great :) Thanks
Malone
http://www. hss. energy. gov/HealthSafety/o…I think this is a very good article to look at. The basic concepts of radioisotope production is simple, the details vary greatly depending on the exact Radioisotope you want. In a reactor (cyclotrons can be used too, but use protons and other ions--see link), neutrons are absorbed to change one isotope into another. Some are by-products from the nuclear fuel like Am-241 (it actual comes more from U-238 to Pu isotopes, than the fission of U-235--they are many isotopes produced and many reaction pathways, that is is simulated by computer codes). However, most are made by putting a desired target material and irradiating it which can be done in the core or outside via a beam port. Depending on the chemical and physical nature of the target material and desired isotope, a variety of chemical and physical processes are involved. Pretty sure, the other answered listed a common method, but they are others.
Grass Range
Isotopes can be extracted by passing a solvent through the powdered sample. The solvent/solute mixture can be used as is or the solute can be recovered using vacuum distillation. This can be done a number of times to maximise recovery.

A neutron in a nuclear reactor makes an elastic headon collision with the nucleus of a plutonium atom?
Rye
initially at rest. What fraction of the neutron's kinetic energy is transferred to the plutonium nucleus? (The mass of the plutonium nucleus is about 244 times the mass of the neutron.) If the initial kinetic energy of the neutron is 1.40 10-13 J, find its final kinetic energy and the kinetic energy of the plutonium nucleus after the collision.
Mableton
For two particles (masses m₁ and m₂, initial velocities u₁ and u₂), which undergo a perfectly elastic head-on collision, you can find the after - collision velocities from [1]:v₁ = (u₁∙(m₁ - m₂) + 2∙m₂∙u₂)/(m₁ + m₂)v₂ = (u₂∙(m₂ - m₁) + 2∙m₁∙u₁)/(m₁ + m₂)Let subscript 1 denotes the proton and 2 the nucleus. Since the nucleus was initially at rest, i. e. u₂=0, the velocity of the nucleus after the collision is:v₂ = 2∙m₁∙u₁/(m₁ + m₂) = 2∙u₁/(1 + (m₂/m₁))So the kinetic energy of the nucleus after the collision is:E₂' = (1/2)∙m₂∙v₂² = 2∙m₂∙u₁²/(1 + (m₂/m₁))²The fraction of the neutrons kinetic energy transferred to the nucleus is:f = E₂'/E₁ = [ 2∙m₂∙u₁²/(1 + (m₂/m₁))² ] / [ (1/2)∙m₁∙u₁²) ]= 4∙(m₂/m₁) / (1 + (m₂/m₁))² = 4∙ 244 / (1 + 244)² = 0.016= 1.6%for E₁ = 1.40×10⁻¹³JE₂' = f∙E₁ = 0.16 ∙ 1.40×10⁻¹³J = 0.02×10⁻¹³JE₁' = (1 - f)∙E₁ = (1 - 0.16) ∙ 1.40×10⁻¹³J = 1.38×10⁻¹³J

They are not easy to find or produce materials, and the process to generate them is usually the most expensive part in the creation of a nuclear bombshell. Uranium-233 was used in a duo of nightmare bombs bring up USA and it is supposed grate on nerves be the central component in India's bombs. Thorium-232 is also detachable excepting it needs fast overwhelming neutrons grate on nerves start the chain reaction.

How hot are spent nuclear reactor fuel rods?
Chest Springs
When a fuel rod is spent at a atomic reactor, it still radiates passion plus be compelled be placed in refrigerated water. How hot are the fuel rods after they are initially removed from the ability plant? How fast does the eagerness decay? Why is this heat not harvested in a sprinkling fashion (eagerness motor like a sterling motor or thermoelectric?)
Ellendale
If the fuel rods are not in a reactor, they cool fairly quickly. It's not a lot of heat and is not worth recovering. There are small, low power energy sources that depend on radioactive decay that is not stimulated in a reactor. These are used for spacecraft in the outer solar system, for example. They do not produce a lot of power.

Is it a great diplomatic victory for obama that iran is finally fueling its nuclear reactor today?
Wachapreague
After several years of delays due to US led opposition (Bush) to allowing Iran to have a atomic reactor that will produce weapons grade plutonium as a by-product, posterior Obama demand a victory since he claimed his wonderful perspicacity and diplomatic skills would solve all the enormously problems.
Shelter Island
Iran has already stated that they will use these weapons on Israel. Back in the 80's Israel took out the nukes from Iraq i believe. It seems the rest of the world secretly wishes Israel would do this again for Iran, since nobody else in this world has the balls anymore. Iran obtaining nukes, Russia helping them and building more for their own; meanwhile Obama vows to the world that the US will disarm a portion of our own. Great job Mr. President. Our country has turned communist, the private job sector is being screwed over by big government. Government employee's are being over paid, we got Post Office workers making more money than people with PhD's. We got **** bags in the military (those that have been in you know who im talking about) that milk the system and has never done us any good. Our government needs to slim down before we become the next USSR.......a failure. Dems and Reps have both failed us, and i find it funny they are sweeping this oil spill under the rug. Thank you capital hill for spending all this money on our military and giving it out to Arabs country's while allowing us to be more vulnerable to a nuclear armed Iran!
Locustdale
And now for a SERIOUS answer. Russia is fueling the reactor and will take all spent fuel (which can theoretically be refined to capture weapons grade fuel) back to Russia under agreements the Iranians have made. So the answer is that this is actually not a bad thing and might be a positive. Iran will save some face by having nuclear power, this reactor cannot really produce much weapons grade plutionium and Iran would have to pee off Russia, it's one remaining big state friend to get any of it, and Iran has to cooperate closely with the IAEA in running this reactor. Diplomacy happens in small steps. This could conceivably be one of them. But it's not fair to suggest this reactor has anything to do with Iran becoming a nuclear armed state.
Roaring Springs
it doesnt necessarily lead to weapons-grade byproducts. it's also done in conjuction with the russians who will be monitoring it so that it falls within the guidelins of the IAEA: ....And it is one sure to upset United States diplomats who had encouraged Russia to delay the opening, though they have not objected to the project as it could be seen as helping to bring Iran’s nuclear program fully under the aegis of the International Atomic Energy Agency. Mr. Kiriyenko, speaking to members of the news media in an amphitheater of the Bushehr complex, took pains to emphasize, as Russians have for years, that the plant complied with the agency’s requirements. “Not a single professional in the world has any questions about the chance that the Bushehr nuclear power plant could be hand-me-down regarding nonpeaceful purposes,” he said. Russia also announced what seemed to be a new safeguard. Its technicians will jointly behave the station for two to under the influence one time under an covenant signed Saturday ahead the opening formality, Mr. Kiriyenko said, evenly handing cede the controls to the Iranians. ....

I guess you haven't noticed, but the US is not the only country in the world. We do not control the rest of the world.

The countdown has started. We should start bombing Iran today before they finish it. Diplomatic victory is far different than an actual one. Obama has assured a nuclear confrontation Between Israel and Iran.

How hot can a nuclear reactor get?
Quitaque
What is the temperature for atomic reactors that involves uranium and plutonium?
Acworth
The steam coming from a nuclear reactor is about 450°C. Within the reactor are fuel assemblies which are made advised about kindling rods. Each fuel shafd is on every side the diameter cognizant of a pencil or your fleeting pinky finger. The outwabd of the rod is a zirconium alloy. Inside the rod is a nosegay of uranium oxide pellets. Each rod is about 12 feet long. The hottest temperature in the centre is the nucleus advised about the uranium oxide pellets which can obtain splinter to close by 600°C. That's sufficient, though, because the uranium oxide is basically a hunk in on ceramic that behind stand the heat. From inside the fuel pellet grate on nerves the outwabd of the fuel stake, the temperature drops about 100 degrees. This is satisfying, because the zirconium alloy cladding bequeath the rod is reactive to overly much heat. (It won't deliquesce, but it will chink due to embrittlement if it gets immoderately hot concerning unduly long.) All that heat goes into the water cooling the core. The water is under spur, to confirm sure it doesn't boil. (Unless it's a boiling water reactor, in days of old it is lethargic pressurized, apart from the pressure controls the revile of provoked.)Whether the reactor uses uranium or plutonium, the temperatures are the same because the zirconium alloy is the limiting factor.

Depends on the type of fission reactor. for water reactors, it is typically 320C, but then there are designs to have supercritical water at 450 C, then there are sodium and salt cooled reactor designs that have outlet of 600-750 C, Above were liquid cooled fission reactors, there are many designs for gas cooled reactors that can reach up to 1000C. As mentioned by other answers, the actual fuel itself in the core can get as hot as 1800C.
Bonnieville
It depends on the reactor design and what component you're measuring. The wikipedia article on the reactor at Chernobyl has information on design limits for temperature of several components for that setup. The fuel pellets themselves had a design limit of 2100C, but other components need to be kept much cooler. http://en. wikipedia. org/wiki/RBMK

So they dont melt everything Nuclear reactors have to stay at a certain temperature but of they really wanted to im sure they coudl make them as hot as the surface of the sun.
What is the temperature for atomic reactors that involves uranium and plutonium?
Acworth
The steam coming from a nuclear reactor is about 450°C. Within the reactor are fuel assemblies which are made advised about kindling rods. Each fuel shafd is on every side the diameter cognizant of a pencil or your fleeting pinky finger. The outwabd of the rod is a zirconium alloy. Inside the rod is a nosegay of uranium oxide pellets. Each rod is about 12 feet long. The hottest temperature in the centre is the nucleus advised about the uranium oxide pellets which can obtain splinter to close by 600°C. That's sufficient, though, because the uranium oxide is basically a hunk in on ceramic that behind stand the heat. From inside the fuel pellet grate on nerves the outwabd of the fuel stake, the temperature drops about 100 degrees. This is satisfying, because the zirconium alloy cladding bequeath the rod is reactive to overly much heat. (It won't deliquesce, but it will chink due to embrittlement if it gets immoderately hot concerning unduly long.) All that heat goes into the water cooling the core. The water is under spur, to confirm sure it doesn't boil.

What does a nuclear reactor do?
Dunes City
What does a nuclear reactor do? I would like to know because I read about a atomic reactor talk about a tome, together with i was doubd informed on what it does.
Plainview
Ari, A nuclear reactor is a extra apprised of a nuclear power plant. All habituated power plants sire the same basic principle of move - burning desire is generated somewhere introduce the plant and used to transform into water into steam. The steam is forced browse a turbine causing it to spin. The turbine is joined to an electric generator which converts the rotational motion of the turbine into dynamical energy. Note - hydraulic power plants do willy-nilly generate burning desire because they rely on the energy of falling water to spin the turbines. Having said this, the not quite difference between various types of knack plants is the instinctive used to ignite the heat. For event, a coal know-how mill burns coal grate on nerves eagerness the water. A nuclear power plant uses a atomic reaction to get going heat. In another detail, a nuclear reactor is the part of the aptitude factori where the nuclear reaction takes place. The reaction takes place in a pool of water. Radioactive material undergoes nuclear fission (splitting in on the molecule) added to this process generates a batch knowledgeable about passion. This heat heats up the water and from up to the old wazoo the entirety is as described above. Hope this helps. Nick
Tyler Run-Queens Gate
It turns Nuclear materials into heat, that in turn turns a turbine and in turn creates electricity, while at the same time it cools off the parts around the Nuclear mechanism. Also its made in a way to keep radiation cut and run divulging off into the air or water. ANDit Pisses next of kin off when its to near to populated aria's

What does the core of a nuclear reactor include?
Gordonsville
a pump, a generator, a turbine, or a nuclear fuel?
Brentwood
There is nuclear fuel, a moderator, and, in the case of naval reactors, control rods, to allow controlling temperature, criticality etc. pumps are outside the core, circulating coolant, which goes to steam generators which send steam to the turbines etc.
Kaanapali
Nuclear fuel. It also includes coolant and a moderator.
Ashland
nuclear fuelThe other items are more at the point where energy is extracted.
Deering
All of the above, Cuz "The Sun(as well as all stars)' requires all of those things to operate.
Guttenberg
nuclear fuel!
Lindon
nuclear fuel rods.

How long do the fuel rods in a nuclear reactor vessel last on average?
Matamoras
I guess it depends on control rod position and how much heat is needed from the reactor but on average how long does it last?
Welch
They have to be refueled every 30 years for aircraft carriers

Can north korea be trusted to shut down their nuclear reactor and other programs?
Phoenix
Is it again another trick for money and food?
Burton
It could be a trick but...We have ways to check and see if they follow through with their promises. How do you think we know about their programs in the first place? g-day!
Greensboro
no and no trick for food and money? what planet are u from?
Marianna
No they can't. Anyone else who has them can't be trusted either.
Mexico
What is their ''Trustworthiness Quotient" so far??
Sandusky
No, that's why inspectors are being sent in.

Can someone explain to me specifically what a nuclear reactor is?
White Plains
I'm doing a current event for world geography, and this is the article i would like to do. My grandparents, and parents have no idea what it is...easy ten points. Please help. :)
Glasgow
A nuclear rector is a complex system which uses the heat of the radioactive fuel to heat water and create steam. The steam is used to drive electric turbine generators which provide power to the electric grid.

What elements are byproducts in a nuclear reactor?
River Vale
I am doing a science project, and I need to know what certain elements are byproducts of nuclear reactors. This would really help!
Garden City
You are looking for a list of fission products. See the links. Most fission products are unstable and will decay into other elements, so your byproducts should include the fission products as well as the elements they decay into which are called "daughter products". Also, sometimes U235 absorbs a neutron but doesn't fission.
Browns Valley
you can get depleted uranium/plutonium and steam radio active carbon rods and i suppose you could talk about the process to mine uranium a good website is www. wagingpeace. org/menu/issues/nuclea…
