This is some what true but in the case of research  there is no “bad” waste being emitted from the reactions that undergo in theses reactors. Commercial Nuclear Reactors or CNRs do produce a lot of residue. They produce this residue by using their fuel so much to the point of radioactive waste. Small Research Reactors or SRRs do not do this, instead of using it up they produce new isotopes that can be useful instead of becoming waste.   So why don't we use SRRs? We do not use SRRs because of financial and safety. The safety concern comes in when the reactors are able to undergo Nuclear fission witch releases huge amounts of heat that no current materiel known to men kind is capable of withstanding. The other type of SRR is safe and financially friendly but does not produce electricity instead it uses approximately 1 million volts DC, but produces isotopes from elements such as Hydrogen witch is found in water.   In conclusion nuclear energy has not ended.

Nuclear Reactors and Batteries

Hydrogen fusion is a promising source of energy. They have made fusion reactors already. Though they aren't going to supply our energy needs because they consume more energy than the make. Fission reactors have been already made and are good at making energy. Unfortunately they have dangerous radioactive byproducts and wastes. Please post anything you want as long as it has something to do with nuclear reactors.

Our main source of  energy right now is nuclear energy. Although Nuclear energy  might seem to be a reliable source of energy, it is not.  Nuclear energy is not a reliable source of energy  because you need to extract Uranium ore from the earth's core which might seem as a good  source of Uranium it is not. This is not a endless supply  of uranium because it will eventually  run out of uranium .   So what can we do to solve this issue? The answer is alternative energy.  Alternative energy  is energy that can be renewed  and that is reliable. One solution is replacing Uranium fuel rods in a reactors core with Tritium. Tritium can be used  as a substitute for uranium because it has the same properties as uranium except that it has a shorter  half life.  Tritium is made by fusing solid  Hydrogen With Lithium  in a Farnsworth reactor.  This also has its problems one major  problem is the radiation and heat that is generated during the process  of fusion. Tritium can be then used as a fuel  pellet for a Nuclear reactor when it is mixed with Deuterium which is a solid. Tritium is also a good fuel pellet because it only has a life span of about 12.4 years, then  it decays into Helium 6 which is very harmless. Uranium on the other hand is not  safe because it has a life span of about 2000 years and it gradually decays into other radioactive material such as Thorium, neptunium, ECT.... This is Called the Uranium - Thorium cycle. The tritium is also ecologically friendly because it  can be made from H1 which is found in water H2O.  H1 is called Portion and is extracted through a process called electrolyses in which water is charged by a D.C current.

Nuclear power costing

I am doing the cost of electricity for a nuclear power plant and was wonder if this costing equation seems right:  Take a plant at the cost of $ 7 billion and produces 1100 MW of power 7000000000/1100/1000= $ 6363.63 per kW Normally the life cycle is 40 years and a weighted average cost of capital is 14.50% So 6363.63 kWh * .1450 = 922.72 The typical capacity factor ranges from 75% to 85% so the average will be taken 80% This capacity factor is then multiplied by the number of hours in a year which is 8760 0.80 * 8760= 7008 kWh a year the plant is running So: 922.72/ 7008 = 0.132 which is 13.2 cents per kWh. Operation and maintenance costs with fuel is estimated at 1.5 cent per kWh Property taxes is at around $0.02 cent/kWh Fuel cycle is at around $0.03 cent/ kWh Waste cost and the decommissioning costs together are 0.02 cents/ kWh So the total cost stands at around 21.7 or 22 cents per kWh ive done another equation out for 3rd generation reactors that comes out at a lower cost. does this seem right? i am not sure how to work out the weighted average capital cost % (that was a figure i took from a site) i will be grateful for any reply

A glimpse into nuclear disaster.

A team of engineers has used an endoscope to carry out the first visual inspection of Windscale 1 nuclear reactor for more than 50 years. In October 1957, it was the scene of what was the world's worst nuclear accident when it caught fire and released radioactive material into the atmosphere.Just over 50 years ago, British nuclear scientists, under political pressure from a succession of Prime Ministers, had been pushing the reactor to and beyond operating limits in an attempt to develop the UK's own independent H-bomb and achieve an "alliance of equals" with the US.When the fire occurred, the scientists were faced with a choice: let it burn, and contaminate Europe, or dump water on it, and potentially die in a nuclear explosion. They chose the latter, risking their own lives to save people who didn't even know there was a problem.That sounds heroic, but the official report into the incident blamed the scientists for the accident, rather than let the US find out about the H-bomb programme just in the days before signing a treaty to share their existing knowledge with the UK.Windscale (now known as Sellafield - the name was changed after the accident) is now in the long process of closing down. Along with jobs, buildings that marked the dawn of the nuclear age are being slowly demolished and moved ... somewhere else. They don't know where, yet, but it will probably end up remaining on site in deep holes (down in the porous sandstone that carries the local water-table).The original piles were shut down immediately after the accident, and the site's AGR reactor was closed down 27 years ago, but it is only recently that they figured out what to do with them, and they are now being decommissioned as a "UK's demonstration project (meaning; "we've never done this before, we'll work out the bugs in remote Cumbria before we try it on a reactor near a city").As part of the decommissioning work, they now need to see what is left in the ashes of the world's second reactor disaster before working out what to do next.I don't know about you, but I'm not convinced that a paper boilersuit would be enough protection. Maybe that's why the chap on the right looks like he's crossing himself...

American Corporations Own UK Nuclear Deterrant

The (British) government has sold its last remaining shares in the Aldermaston Atomic Weapons Establishment in Berkshire to an American company.The fee paid by California-based Jacobs Engineering has not been disclosed.The sale of British Nuclear Fuels' stake means Jacobs has control of one third of Aldermaston's operating company, AWE Management.The other two thirds were already in private hands. They are split equally between American defence giant Lockheed Martin and the British plc Serco.Aldermaston is responsible for the production of warheads for the Trident nuclear deterrent programme and its planned replacement. Some opposition politicians claim that US control of UK weapon production breaks the "no technology sharing" conditions of the nuclear non-proliferation treaty.BBC story

Tell me more about nuclear power as source of electricity.

Hi !Fishes can't see the water they are in ! That's why I need your personal and external opinions and view.The first source of electricity in my country (France) is nuclear.In a previous forum, I've noticed that a lot of Citizen of USA consider Nuclear energy is too much polluting and too much expensive (democrats candidates for US election reject the idea of more nuclear plants), and that it's not seen as a serious solution to reduce pollution and CO2 emission, etc ... In few words : you seems to dislike it. So, I would like to know why exactly, and that you tell me more about what you think about it.Here it's quite different. Nuclear energy is seen as a mean to be energetically independent. It's a mean to pollute less. And it's almost a local speciality, like are crepes, baguettes and croissants.The main producer is EDF (which stands for Electricite De France (electricity of France)). Until 1999, EDF had the monopoly (and that was better and safer IMHO). Since then, because of EU regulation, we've been forced to open the market ...Here are some data :EDF is one of the world's largest producers of electricity. In 2003, it produced 22% of the European Union's electricity, primarily from nuclear power:nuclear: 74.5%hydro-electric: 16.2%thermal: 9.2%wind power and other renewable sources: 0.1%Its 58 active nuclear reactors (in 2004) are spread out over 20 sites (nuclear power plants). They comprise 34 reactors of 900MW, 20 reactors of 1300 MW, and 4 reactors of 1450MW, all PWRs.---In 2006 :- nuclear : 85.7%- hydro-electric : 5.0%- thermal : 8.1% ( coal : 3.3%, gas : 3.2%, petrol : 1.6% )- others renewable : 0.9% (wind, sun and co)- others : 0.3%---

Scientists plan to ignite tiny man-made star

From www.telegraph.co.uk:"While it has seemed an impossible goal for nearly 100 years, scientists now believe that they are on brink of cracking one of the biggest problems in physics by harnessing the power of nuclear fusion, the reaction that burns at the heart of the sun.In the spring, a team will begin attempts to ignite a tiny man-made star inside a laboratory and trigger a thermonuclear reaction.Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy. Full article.This is big medicine, because while we have (more or less) successfully harnessed the power in nuclear fission, we've yet to find a method of using nuclear fusion for power (outside of experimental/weaponry uses). It is important to note, however, that this initial experiment, while big, won't be powering your home or office just yet-even if it does work, there's still quite a lot that would have to be done to build a nuclear fusion power plant.Still, it's heady stuff, the energy source of dreams-a world powered by nuclear fusion fueled by hydrogen, one of the most abundant elements in the universe-only now that dream is looking like it could, possibly, maybe, eventually, become reality.And now, a word from our sponser resident particle physicist:The NIF at Livermore uses small (BB-sized) pellets of liquid hydrogen (technically a deuterium-tritium mixture) encased in a shell. The pellet is illuminated by a terawatt laser split into 192 sub-beams all focused on a poiint. The outer shell of the pellet is vaporized and a shockwave compresses the hydrogen to the point where it should start fusion.The whole process is over in roughly a microsecond. If you keep dropping pellets into the chamber, then you get a series of pulses, but as soon as you stop, everything shuts down.The NIF (like the NOVA laser before it) is being run at a weapons lab, because the kind of fusion it can do (individual microsecond pulses) is most useful for studying the physics underlying thermonuclear weapons. It is probably not a viable technology for continuous power-generation fusion, but it is necessary for understanding how to make that sort of system work.

Nuclear powered throwies keep Boston on terror alert for sixth decade, seventh on horizon.

OK, so it's an attention-grabbing headline, but the potential is now there.Radio-isotope batteries (the same things that have kept the Voyager craft alive since the seventies) can hold a million times as much charge as a standard chemical bettery the same size.As radioactive isotopes decay, the charged particles they emit are trapped by semiconductors and turned into useful current.  Past versions of the battery have used solid semiconductors, which suffer damage from the radiation, so need to be large to survive as long as the isotope.  Now, a team from the University of Missouri has developed a liquid semiconductor that can survive the damage whilst having much less bulk, and have put together batteries the size of a coin.  They are working on much smaller versions, capable of powering micro- or nano-scale devices.Just imagine the possibilities...University of Missouri - Nuclear battery linksBBC Story

A Disturbing Store Room

We've just returned from staying with friends in Geneva, where we slept in their (large and airy) basement. Next to the bedroom was the room our friends used as a store room - their nuclear bunker! When their house was built, it was a legal requirement for all homes to have a nuclear bunker.  A stocked, functioning nuclear bunker. The door is steel, filled with concrete.  It doesn't have a lock - that huge yellow bolt and spanner hold the door shut against invaders.  The door on the wall is an escape hatch, in case the house collapses on the main door, and the machinery in the corner is the air filter. The shelves double as beds, and the toilet is a bucket with a lid. I found it fascinating, and, to be honest, disturbing.  It took me two days to "get around" to going through and taking these photos. I grew up during the tense days of US/Soviet nuclear proliferation, when Threads wasn't just a disturbing drama, it was almost a government information film.  I paid attention at school - I knew what nuclear weapons really did.  To most kids, they were a cool way of destroying a bunch of stuff (even more so today).  To me, they were (and are) flatly horrifying, and the stuff of genuine nightmares. I look forward to when things like reduced to the kind of novel feature that ranks alongside "original fireplace" or sash windows.

Seeks energy independence not by halting all oil imports but by "making sure that our nation's future will always be in our hands."DemocratsHILLARY CLINTON: Says she's "agnostic" about building nuclear power plants. Prefers renewable energy and conservation because of concerns about nuclear power's cost, safety and waste disposal. Wants to spend $150 billion over the next 10 years to cut oil imports by two-thirds from 2030 projected levels, with some money going toward alternative energy.JOHN EDWARDS: Opposes nuclear power because of cost and safety concerns. Favors creating a $13 billion-a-year fund to finance research and development of energy technologies; wants to reduce oil imports by nearly a third of the oil projected to be used in 2025.BARACK OBAMA: Says the U.S. can't meet its climate goals if it removes nuclear power as an option but says such issues as security of nuclear fuel, waste and waste storage need to be addressed first.

Radioactive lift controls recalled in France

NEW DELHI (AFP) - India's atomic safety body said Thursday that radioactive scrap metal which found its way into buttons installed into lifts in France had been traced back to a western Indian foundry.At least four Indian firms were involved in the manufacture of the components, an official said, but it was still unclear where the contaminated scrap originated."We are tracking back the whole chain," Satya Pal Agarwal, head of the radiological safety division of India's Atomic Energy Regulatory Board, told AFP."We are taking steps in each place. Exporters have been advised to buy monitors to check their materials before exporting."France's Mafelec firm delivered thousands of lift buttons to Otis, a subsidiary of the US elevator company, which installed them in at least 500 lifts in the country over the summer.Otis has said it is now in the process of removing the buttons, after France's Nuclear Safety Authority announced Tuesday that 20 workers who handled the lift buttons had been exposed to excessive levels of radiation.The French nuclear safety agency has said the lift buttons contained traces of radioactive Cobalt 60.AFP articleSteel items imported {into Sweden} from India showing faint traces of radioactivity were found in Sweden, before the same substance was traced on Indian-made lift buttons in France, officials said Wednesday.The levels of Cobalt 60, a radioactive form of the metal, were considered harmless and the steel components have not been recalled, the Swedish Radiation Safety Authority (SSM) told AFP."Dutch customs discovered that a shipment of industrial flanges from India to Sweden showed traces of Cobalt 60," SSM spokesman Mattias Skoeld said.Focus Agency feedFrench elevator maker Otis said it would remove the buttons from hundreds of lifts it has installed after a radioactivity scare over Indian-supplied materials.The company made the announcement after France's Nuclear Safety Authority (ASN) said 20 French workers who had handled buttons used in lifts had been exposed to to excessive levels of radiation.An Otis spokesman said the firm's plan to remove the buttons "concerned 500 to 600 lifts out of the 2,500 that Otis has installed, modernised or repaired between August 21 and October 9 even if there is no danger for users."The ASN classed the incident at factory of the Mafelec firm in the east-central French town of Chimilin at "Level Two" on a scale of seven because of the exposure of more than 10 people to doses exceeding the reglementary limit.SA Times article

bike powered wheat grinder

Any one with a food storage probably has wheat, i'de guess that 50% of those people don't have wheat grinders and if they do its either a puny hand grinder that would take 3 days to grind enough wheat for one meal, or an electric grinder and their assuming there will be electricity after every major disaster. there are plan's over the internet for hooking up bikes to hand grinders most of the plans i found require you to send money to the creator and they will send you plans so any ways i'm cheap and this sort of info would be to important to cost money if something bad happens (i mean really BAD like meteor showers, nuclear war, gamma bursts any thing like that) so what i'm wondering is there any plans on instructables for making a bike powered wheat grinder

Seedbank = Arctic Bunker

Norway has built a pretty awesome1 seed storage facility over 400 feet under a frozen arctic mountain. Further chilled by air conditioners to reach -0.4F, the seeds should be safe for up to 1000 years. Hooray for biodiversity!From an AP article:The vault will serve as a backup for hundreds of other seed banks worldwide. It has the capacity to store 4.5 million seed samples from around the world and shield them from man-made and natural disasters.Dug into the permafrost of the mountain, it has been built to withstand an earthquake or a nuclear strike.The seeds are packed in silvery foil containers -- as many as 500 in each sample -- and placed on blue and orange metal shelves inside three 32-foot-by-88-foot storage chambers. Each vault can hold 1.5 million sample packages of all types of crop seeds, from carrots to wheat.1Did you see Alien vs. Predator? Remember the big Antarctic bunker/pyramid? The Norwegians clearly did too.

could we actually travel through space?

OK, earlier today i was watching sci fi science on-demand and it was the episode where he discussed hitting mars with several astroids and i thought of something: what if instead of using a normal rocket,why not use the only thing that we know of that is more powerful than a nuclear reaction? anti-matter! no, it is not a myth, CERN has been harvesting the stuff for decades, yet all they have is about 10 pounds or so. most likely less. in theory, we could make a two compartment chamber with an air lock between the two chambers, and in each chamber put a few particles of a natural substance and its anti- substance in the separate chambers with a remote module to open the airlock separating the chambers while we are several hundred miles away, with two possible,reasonable theories:1)the chamber skyrockets through the atmosphere and into the great unknown of the skies and stars 2) we create a new grand canyon in the middle of nowhere, harvest the profits of the tourist attraction and try again until we get it right, if we fail 2) then we have several hundred grand canyons!(whew!!!!!!!!!!)

do it yourself 4 wheel adult sized pedal bike car

In spring I got idea to build a 4 wheel pedal car for my son. To use wheels from old bicycles, to make it as small and light and simple as possible and to make it possible to fit even an adult person. I was really disapointed surfing internet, as I found almost no free ideas, plans or experiences how to do it. It is no nuclear science, people would invest millions in their know-how, so they would need to hide it! Now it's autumn now and our car is done. I decided to share my experiences and detailed photos as free plans with other people, interested in self buliding pedal car of that kind. I wanted my 9 years old son to learn basics of construction and working with metal and wood. He did almost all hand works by himself and he is very proud on it. It is a very good way to move your child from TV and computer games! It is all on our 4 wheel pedal bike car web site

alternative ignition of thermite

Allright im looking for information on a number of different ways to ignite thermite. sure we've all heard of magnesium and yes it's usually third or fourth time is the charm also potassium permanganate which is pretty cool too and the ever popular sparkler of course lots of companies have taken out the magnesium chlorates and perchlorates from these sparklers and are now selling crappy ones without hazmat fees for them so they don't work worth a crap. i read an article from a guy stating he used simple visco fuse to light it even though ive heard it won't work but perhaps it depends on the mesh as in much finer. i use the dark german aluminum about 625 mesh and it will coat any and everything it touches. really though guys let's come up with some ways to lite thermite outside of tradition and share these methods of doing so along with how to obtain materialsin conventional and unorthodox ways because without frst time reliable ignition it's just no fun. also the first fire mix, much like the thermite ignition mix at united nuclear what exactly is it made of and how are some ways the monetarily cahllenged can obtain it and of course the not so challenged.
