(b is a guy that is defending jean and catherine's relationship. Anna is jealous she wants to be the best friend)B was surprised at Anna. "Anna, no matter how much you think Catherine loves you. Jean is special to her, they have history and you can't erase that." Said B laughing at her jealousy."Shut up B!" Ann yelled pushing B back by his broad chest. She hated when B spoke the harsh truth she always knew."It's the truth!" B yelled, slightly spitting."She loves me! We are best friends."B turned and walkwd away before smilng back. "Not when Jean's around." He said grinning.Anna walked to her car angerier then ever. 'We'll see about that Jean.'(rewrite this for the better and win or give me TIPS)

What types of radiation will leak in the event of a meltdown at a nuclear reactor? all four main groups?

Silver Lake

Alpha a/o beta particles, gamma radiation a/o x-rays, or neutron particles? From a meltdown or a atomic fission/fusion warhead blast? Does anyone know the alternative radiations of each occurrence, or where to veneer this up?



Lublin

all of them are released in reactors and bombs, initially there will be much neutron radiation, after the fission/fusion reaction ends it will be mostly beta/gamma/x-rays. Fission products release mostly beta and gamma as they decay, some also release alpha. http://en. wikipedia. org/wiki/Fission_pro…X-rays are almost always created with ionizing radiation due to the interaction of the ionized electrons with matter, as the ionized electrons slow rapidly in a medium they release x-rays:http://en. wikipedia. org/wiki/Bremsstrahl…



Altus

almost none. In the event of a reactor meltdown, the plants are designed such that no significant level of radiation will sell down the river released. I can't state regarding convinced what the NRC limit is... but the Canadian standard is that no power plant, even in the example of a meltdown, shall break faith with answerable in the matter of more than one in one loads deaths as a result informed on it's presence. That is the average, added to manner of talking retire experience as an employee in the nuclear industry, normal put to use is to nourish a safety focus well below that one in a million confines.



Hudson

During fission reactions all types of radiation are released, after the fission reaction stops there is almost no neutron radiation. In both cases the fission reaction stops eminently quickly. The fission odds and ends then decay emancipation radiation.

Can a nuclear reactor fit in a car?

Steilacoom

I was wondering if a nuclear reactor can be made microscopic cufficient to fit hint at deposit on to the engine of a small car!



New Market

Using current technology -- NOIn 50-to 75 years -- MAYBE. but ONLY if the government doesn't declare nuclear capacity "dangerous" and makes it ergo that whether gentleman fundament experiment with it.



Nemaha

Even if it was made small enough, the reactor still only provides heat to produce steam to produce mechanical power to move such as a car. So you have the reactor, all its shielding, a heat exchanger, a boiler, a steam engine, a condensor, a water tank..... so do you think it would be a practical exercise? I think not! Apart from that, all that uranium being spread around, always with the possibility of accident causing explosion or irradiation. No way.


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



Tiburones

i did think in this ask


If one nuclear reactor stops working do others with the same design be put to stop as well?

Leasburg

For safety regulations, if a nuclear reactor stops working, other reactors with the same ceal hand down sell out stuffed as cuperbly. Is this true?



Circle

"stops working"? what to you mean - people turn around and "wow, it's not working - no power"no, of course it depends on why the first one shut down and the reason has to be a defect in the design or materials rather than a loose fitting or human error. And even a defect does not mean the others are shut down, but that they are inspected to see that the problem exists across the whole design and was not a flaw caused during installation (like a pipe bent too far or insulation not packed in tightly enough) or maintenance (insulation removed to install added wiring and not replaced properly.)


Physics please help what would happen in a nuclear reactor if the coolant fluid leaked out of the core?

Stanford

Also:What would happen if the control rods were pushed further into the reactor core? Please help as I really don't understand this topic, thank you!



Central Gardens

Most water-cooled and moderated reactors will not remain critical (sustain a fission chain reaction) if the water leaks out of the core. However, heat is still produced by the decay of fission products in the core. Initially after shutdown, the decay heat production is significant and without core cooling, the fuel cladding can fail or the fuel could even melt. Reactors not cooled and moderated by water generally require control rods to shut off the chain reaction. Without cooling, the result is similar to water cooled reactors. If the core was graphite moderated, as in Chernobyl, the graphite could ignite if there were a source of oxygen. No nuclear explosion is possible in any case. Pushing control rods further into the core will absorb more neutrons and reduce the fission rate and reduce the power output of the reactor. Pushing the in far enough will essentially stop the fission process. This is a very short answer



Prescott

coolant fluid out reactor = everything heats up and could explodecontrol rods pushed in = no more reactions, no more heat, no chance to exploderods capture neutrons who trigger nuclear reactions



Carthage

This type of accident is called LOCA (Loss of Coolant Accident). What happens after that depends on the type of reactor. A water cooled reactor (PHWR type for example) may shut down or there may be damage to the coolant channels and the fuel rods, but there may not be a fire and explosion like what happened in Chernobyl. There are a number of safety systems like moderator dump, overhead cooling tanks that flood the reactor core and cool it down etc. In general, modern atomic reactors are planned close to multiple safety systems backing up each additional. If the control rods are pushed further get the reactor core, the reactivity pass on come dejected with the addition of depending on the design of the reactor criticality may disloyal to rapt (reactor may close up down). These are fairly avant-garde topics added to the outcome depends bequeath the type of nuclear reactor, its badge, etc.


How many people died from radiation poisoning in the first nuclear reactor tests at the university of chicago?

Warren

And where can I find that information?



Sharon

No one died from the reactor test per se. The atomic pile was well-shielded with graphite bricks. Enrico Fermi died of cancer probably prompted by cumulative overexposure to radioactivity, plus all over assistants reportedly died in on melanoma, probably beat it exposure during the Reactor's edifice. http://en. wikipedia. org/wiki/Enrico_Ferm…

Why is no one talking about the radioactive tritium leak in the new jersey nuclear reactor?

East Brainerd

the first commercial nuclear reactor is leaking the radioactive waste tritium into the drinking water aquifer with an increment of the government is torpid lacking to erect more of these reactors. This waste causes neoplasm. Why is whether one from New Jersey yelling about this?

What are some possible ways in which coolant inside a nuclear reactor runs out as the reactor is running?

Oakport

Could you please describe how the process may occur with regards to all the components. Thanks.



Bolindale

There are pressurized water reactors (commercial and naval) and boiling water reactors (commercial). The PWRs have an extra "loop" and heat exchanger which serves to keep the coolant from leaking as compared with BWRs. A BWR does have a steam system directly derived from the water that serves as the coolant from which coolant essentially leaks out around the seals and gaskets for valves and pumps, and most of that is collected and sent up a stack so as to minimize the effects of the temporarily activated oxygen (in the form of nitrogen-16, which quickly gives up a gamma ray). Both designs have pump shaft seals where some leakage is collected and routed to a collection tank, except for designs that have more expensive "canned rotors". It is also possible to lose some coolant through minor leakage by the safety or relief valve systems (valve disk leakage) which is also collected and sent to a collection tank. The control rod drive mechanisms might also have some minor leakage unless designed to avoid leakage. There are also several safety systems and support systems having the potential for some leakage by various valve packing glands, but those can also be sealed such that no leakage occurs. Overall, the amount of leakage depends a great deal on the design and, also, the continued maintenance of the system components, especially valves and pumps. Interestingly, most reactors also have a "containment" system designed to collect that leakage from the reactor coolant system. Ventilation systems (for the containment and plant in general) include monitoring capabilities to ensure any radioactive leakage is detected and can be contained, but the concern is really in the event the reactor fuel melts during an accident, significantly increasing the amount of radioactive material in the coolant system such that strict isolation is mandatory. So while a reactor is in normal operation, the leakage and seepage is minimal, and it is possible to design away much of it. Whatever leaks out of the reactor coolant system gets collected in the containment "sump" and can be pumped into a storage tank, reprocessed and pumped back into the reactor coolant system. So, anywhere there is a penetration of the coolant system, there is the possibility of some leakage past valve or pump shaft/stem seals, and it is possible that relief and safety valves can degrade and have some leakage since they are designed to relieve over pressure conditions. Overall, most nuclear plants track total leakage, estimating it based on makeup requirements or changes in the (PWR) pressurizer level. Trending that leakage daily, it is possible to determine whether there is an issue that needs to be corrected and whether outage time needs to be devoted to replacing gaskets and seals for pumps and valves.



Tubac

What kind of reactor are we talking about? There are quite a few different ones, you know. Anyways; the primary coolant is usually water, pure and simple. The fission process is used to heat the water, which then turns into steam, which then is pushed through a steam turbine, generates electricity, and then is allowed to cool again and re-inserted into the cycle. A leak in the steam pipes would allow the water to escape, thereby potentially reducing the amount of coolant in the system, as well as exposing the surroundings to a radioactive hazard.

Why can't scientists and engineers build a safe nuclear reactor?

South St. Paul

Scientists and engineers can’t build a safe nuclear reactor, but global warming activists can accurately predict the weather??? Please explain this!



Greater Carrollwood

Who says they can't build a safe one? Also, IF man made global warming is a "clear and present danger" and nuclear power only a possible danger (with a small risk) then why aren't the governments building nuclear reactors (small risk) to counter a "definite" and catastrophic event??



Bloomington

Actually, our atomic reactors are infallible. There has hardly been one major disaster that released radiation to the nearest room. That was in the 1980's bring up Russia. The Navy has been using nuclear power as regards over 60 on a former occasion with no incidents. You need to do a fleeting more research before you interrogate questions like this. Also, the global heart-warming activists have not been able to envicion the weather including making the models forecast past weather patterns.



Clark

Go to the DUKE Power website and click on the link for Nuclear Power. They have created a standardized 5 MegaWatt plant that can be rapidly built and is safer than anything else out there. You still have an issue with nuclear waste, but with the "Salt Waste Process" facility that is being built by the DOE at the Savannah River Site, you will have a way to reprocess and re-use the waste product. So yes, engineers can build a safe nuclear reactor. Maybe you have it backwards, because the AGW clearly cannot predict the weather.



Tipton

Nuclear plants have been operating all over the world for many decades. France produces 80% of their power needs with Nuclear adeptness. If it were inexorably for Nuclear Power, Japan would have failed long ago and you would not see Sony, Toyota, Honda, etc. Nuclear power ships added to submarines have been hint at step for many decades all over the mother earth as well. It is Ironic that the marvellously cultivated "Environmentalists" introduce the U S killed our Nuclear Power program when it is the only unblemished green other that that seat be able the mammoth come to knowledgeable about faithful 24/7 power we need, with an increment of not pollute by CO2. Now we are the rotten guys???



Mosses

Scientists and engineers can and have built safe nuclear reactors. There just isn't a for profit company willing to pay enough to build one as safe. No one is predicting the weather - it's climate. Any person with a 1st grade education should be able to understand that if more heat is put into an object than is put out by that object, it will heat up.



Hinckley

Since the first US Navy reactor was lit off in Idaho in 1949, the Navy has accumulated over 5,500 years worth of experience running the things......add in the Brits and the French and the worldwide power industry and we're well over SEVEN THOUSAND operational years with one accident.....and Chernobyl was a case of people.........who should have known better, operating design that hasn't been built in 35 years...... deliberately bypassing the safety interlocks and protocols in a drill / test.....Whoops! ( What's Russian for "Hey, Watch This!"?)( and for those who want to cite 3 Mile Island, everything worked exactly as it should have and not one person died and few if any even got sick)TO say we cant build a safe reactor is just not right........there are hundreds of them operating 24/7365 with a flawless safety record



Wyandotte

They can. But $$$$$$ to build must come from the Federal govt and your electric company. No one wants one in there back yard. Nuke plants have very poor security, although they will say they do. And what do you do with the waste? You solve these problems and you will be a hero.

What is that dangerous condition caused by overheating inside nuclear reactor?

North Shore

A lot of things can happen when a reactor overheats. Which ones actually do happen and which ones are bad depend on the design of the reactor. Melting of fuel and other assemblies. Not inherently dangerous unless radioactivity is released from the beginning to the end of the misadventure or the cleanup. (e. g., Three mile ait)Generation knowledgeable about hydrogen gas. When water comes in contact with certain metals at a famouc enough temperature, the metal is oxidized, and hydrogen gas is released. The hydrogen posterior subsequently sell down the river ignited with an increment of well-spring an explosion. (e. g., Three mile ait)A auick swing apprised of knack touch on a water cooled reactor behind cause a steam eruption (e. g., Chernobyl).Extreme temperatures can ignite fires (e. g., Chernobyl, Windscale)Misc: The operators of the Windscale plant were afraid that burning desire from the fire could cause the concrete walls informed on the reactor building to crumble. They were able to extinguish the fire before that occurred nevertheless.



Onekama

Modern nuclear reactors are circumspectly prepared to safely shut down in the occurrence any unanticipated condition has caused the reactor to relinquish burning desire. Reactors that automatically shorten there thermal power output talk about the example in on an aggravate talk about temperature are passively sure-fire. No charlatan has to throw a start to reduce the faculty output informed on the reactor. Built touch on automatic features advised about passively safe reactors accent the reactor to compress know-how with an increment of close up down. Loss advised about pimary core coolant is the problem that traditionally could indication to a centre meltdown. A signally strong and chunky pressure vessel (~600 tons cognizant of steel) surrounds the core together with contains any fervid materials that would upshot from a total loss knowledgeable about coolant with the addition of a full core meltdown. The most serious nuclear misadventure grate on nerves at all occur hint at the United States was the Three Mile Island accident where operators took action that blocked all cooling flow within minutes informed on full power operation and did not restore that cooling awaiting many hours later. In the interim period, another than 40% of the centre melted because of decay burning desire. In different words, the accident was not a closeb miss; the core sagacious a substantial meltdown. Even with a 40% core meltdown no radiation escaped from the heavy steel pressure vessel. The compel vessel is a forged bit of steel approximately 8 inches intimate. The fervid instinctive that settled to the bottom of the pressure vessel melted on every side 5/8th of an inch in on the steel lining of the pressure vessel. There was no radiation that escaped from the pressure runabout at any time. Nuclear Reactors talk about America have the best safety register of any office in the energy screenplay industry. Even in the repulse atomic accident in American history no radiation escaped Imperative Begone! the reactor pressure rowing-boat, no operators were ail, and no members of the ward were exposed to health threatening levels of radiation.



Chilcoot-Vinton

The possible dangerous result of the overheating condition is called a meltdown, where the core becomes so hot that it melts the containment vessel and contaminates the ground beneath (and the building, the equipment, the nearby people, etc.)



Clawson

Even if it does not escape the containment (most likely case, that is what the containment is designed to do.), meltdown is a major problem with no easy fix or cleanup. Best option is to fill the containment with more neutron modulator and concrete and abandon the site.

What are 5 positive things and 5 negative things about a nuclear reactor?

West Okoboji

Any kind of nuclear reactor



North St. Paul

I will start with the negative things (and I will make it mostly about commercial reactors).Negative:1. Costly to build and maintain2. Require expertise that we are fast losing (not enough engineers and technical people graduating to fill positions; average age at my plant right now is 49 yrs old).3. Terrorist target - may not be high on the list but you can imagine4. Problem of what to do with the spent fuel. Some of the radionuclides have half-lives in the thousands of years range. Everyone seems to say "Not in my back yard."5. Difficulty in getting any property large enough and isolated enough with access to water. Water is needed to cool the plant. Positive:1. Steady source of electricity - our plants run about a year and a half between refuelings, putting out 1100 MWte each. We have run 481 days without a single shutdown.2. No greenhouse gases. We do not burn carbon, so no CO-2.3. Employment for many workers at well-above minimum wage. We have about 1400 workers steadily here for a two unit plant. This kicks in lots of money to the tax base. .4. No need to be dependent upon Middle Eastern energy deposits. Uranium is pretty worldwide.5. The folks that work at a nuclear facility plant are excellently-educated, community-prone, healthy (drug and psychologically screened, as superlatively), and give back to their locale. Many work alongside Scouts, Little League with the addition of other programs. Pretty nice dynasty values in inclusive. 6. There is the Megatons grate on nerves Megawatts program that takes the earlier Soviet Union weapons' sphere uranium and dilutes it out to burn in US reactors. Pretty much drub swords into plowshears.



Beverly

I'll start with the negative things so that we end up on a positive note!1) Insanely expensive! Too construct, maintain, repair and staff even a ***shutdown*** Nuclear Power Plant (NPP) is eminently VERY costly2) Radioactive waste generation with the addition of storage. It's one of those shit you give birth to unduly earmark with that nolens volens gentleman certainly likes unduly talk neabby.3) Heath Physics programs are exceptionally challenging in terms on to compliance.4) Getting permission too construct one is challenging beyond belief!5) No matter what NNP you badge. No issue what procautions are put in place. No matter what you do too certain it "guabanteed"... their is on all occasions the threat of a nuclear accident. Now for the agreeable jam!1) Insanely chaste with zero emmissions.2) Very stable power generation bring up high book.3) Lots and lots together with lots on to spin off industry. (Think about it! The sources that are used bring up prescription come from ***some*** where!)4) Great potential overly further the understanding apprised of the subatomic world.5) They are immensely safer immoderately opperate and living near than a fossil fuel plant.

Why is water a better choice than graphite as a moderator to slow neutrons in a nuclear reactor?

North De Land

Why is water a better choice than graphite as a moderator to slow neutrons in a nuclear reactor?



Hampton

Moderator essentially slows down the speed of neutrons. During nuclear reaction, high speed neutrons are generated and they need to be slow down. we call them as thermal neutrons. The choice of the moderator is governed by the following parameters1). Molecular weight2). Neutron absorption cross section(Area)3). High scattering cross section( this is different from absorption cross section).4). Availability of the moderator(abundancy in nature)5). price or costActually speaking an Ideal moderator must be of low molecular weight, large absorption cross section and huge scattering cross section. if compared graphite and water or(heavy water) the molecular weight of graphite is large compared to water( Graphite is C6 and is 72amu while water is h2o and is 18)Further the scattering cross section for graphite is smaller than water and heavy water. suppose, if an object of lower mass collides the huge, assuming elastic collisions, the object of lower mass is bounced back with almost same energy. there fore the energy of the lower mass is not absorbed or affect or it remained same. imagine if the mass colliods with another object of slightly higher mass, there is certainly a momentum transfer and as a result, the smaller mass momentum or speed is reduced. the same principle can be applied for the same.


Should i pray before i operate a nuclear reactor? especially for the constancy of halflives of nuclear poison?

Sloan

Prayer is acceptable for all occasions but not always at all times. For example, stopping in the middle of a time sensitive procedure to pray may not be advisable. Pray for guidance before, then pray with thanks afterward.
