the tire society computers that are similar to the dental governments that go crazy for your data. explain how to use technology's work. that's how they can also watch it. now, the nuclear radiation comes in waves and sometimes gets under the skin. radioactive and electro magnetic rays can penetrate deep into our bodies, take x rays that can cut through anything to body luggage costs penetrating rice into their atomic structure. but what do they pose for that in more coming up the would welcome to tomorrow. today

the site is cat brown. when it comes to new cape how it all depends on the rest of nuclear power, produces aggressive radioactive waste. but what if instead of uranium, we were to use the mass, whole story, and waste from story empower stations, supposedly. and it's very ation for much shows at times and uranium based nuclear waste. it's also supposed to be meltdown pretty. but all of the claims for real, the nuclear gets a pretty bad rap, and there are some good reasons for that. in the, towering much from japan, you could read it still it was a person like mer union has suffered the news disasters in the history of

nuclear, faster on known proportions. we'll see if we could have nuclear energy without the problems, a new meltdown. no weapons under lot less waste. well the is a new p a c for fuel that set to do that. let me tell you kids about story. you told him we've learned about it for decades. in the summer of 1965 scientists at the oak ridge national guard tree in the us. right. and usually a history of how it up a ground breaking you react to. it was fundamentally different from most of the designs because it's nuclear feel didn't come in solid form. instead, it was mixed into the cooling that's circulated through the system, which instead of malta was molten salt, i would call them the records from studying success. it did things and in the 1960s that we still can't do in reactors today. kirk sorenson at the self proclaimed

story, and if i'm jealous his company slide, energy is working on a modern version of the of courage react to come up with things that are going to make it easier and better and safer and faster. but at the heart of it really use the technology if it was originally put forward by often wineburgh at oak ridge national laboratory in the 19 sixties and seventies. the vision now is the same as back fence to generate energy from story and it's a frankly radioactive chemical element. that's $2.00 to $3.00 times more abundant in the crust than uranium, which is what we mainly use to power reactors. today. let's take a closer look at the chemical elements and that reisa types nuclear fuels we use today, like you, radium 235, a file. this means when the ice of types nuclei a hit by a neutron, they'll actually break apart and release monique drums, but split more items and so on. this nuclear chain reaction produces heat which compound a reactor. but the most common ice,

a type of story m to 3 to complex split. it's not for style, but fat tile. when a neutral on hits it's optimal, usually just absorb sex. sometimes it tends authority into 3 tree. no chain reaction yet, because after about 20 minutes or so, it decays into po, tucked 10 am to 33. which after about a month, the case into uranium 233, about those splint. so the system, the incense need to stall top if you lock up the, a bit of a stuff starts up. will store amounts of fuel to get the ball rolling. if you like to know minutes, a professor of nuclear physics at the university of bombing them. and once that is happening, we can start to grow in from the story of this very until the uranium of that keeps the system working. the system. ready is set to be efficient because the molten soul can serve as base of fuel on the coolant. mission, reduce costs, not turning in operation, but also in the construction of the cons. that also be less

radioactive waste and conventional reactions. and much of it would be mostly gone off to hundreds instead of thousands of us and story a molten salt. we act as he'd get fetch me. know you pretty tiny of which could be used to build nuclear weapons. all of this really seems like molten salt we have doesn't story, are much agent having the test react to run it full. tell us more than $13000.00 and became the world's fast react set to run on uranium t $33.00 produced from for you. then government officials pulled the plug. what happened as well for one, the experiment didn't always run smoothly. the the experience with the martin salt reactor expects that he meant in oakridge was pretty big. this is i'm the amount of success to reset just new policy. the reactor trouble even reaching its design power level. it then did not run smoothly to shut

down a lot. and in the 4 years that at all, they teddy don't fit for me about 50 percent of the time. that will also have questions about the materials in touch with the liquid fuel. the low is specifically designed to which stands extreme heat, corrosive salts and radioactivity share tracking and other concerns with the radioactive gas by product tricia, in which it already begun to eat away at the equipment become leaking into the environment. when you build something for the 1st time, you don't get everything right. you, you do find issues. that's why we built experiments all technical issues aside. the real reason why the program was under it was different like rich dereks to open wine bags, right? or problem is not the term right. there is a pull one problem, it's just different from the main line. main line met pressurized holt, reactance that goes

a much better tested design at this point that had been problems there too. but those were not as a pattern as the problems with the consortium. today, there's a whole bunch of companies working on different molten salt, react to designs. they're all, for example, concepts to fuel a molten salt, react with radioactive waste, from conventional reactors tax or incense company. is planning to build a small test reactor. we've gone through a number of generations of nuclear reactors and other technologies you most often do one initial generation. and it's time to, to continue on extensive to understand these advantages that can be infused into the design. china is currently testing the molten salt process and the guy be, does it an india home to the world's largest store and resides, is also working on reactors to utilize them as possible long time nuclear struck today. you know, there's one level of,

of it which is sort of talking and, and saying you're going to do things. but the much more important aspect is to actually be doing it. and this might prove a lot how did the flushing 3 d animation suggest a multitude. so we act as really safer than conventional plots. any good regulator, we'd be asking a lot of questions to a designer. how was this reactive behavior? there's a fire. what is this an earthquake? what is your operator press this button and stuff that, but those are not easy questions to answer. to build a story and react to the costs around 800000000 your raise compared to several 1000000000 for a conventional one. the regulators might require changes to react to designs that make them more expensive to build money will also be needed for to research and to build an entire infrastructure and supply chain from scratch. the last couple of

years we've had more capital than we've ever had before. we proceeded much faster to be around before, but it's still a very, very small amount compared to where we need commercial story a molten. so we access a still use a way, at least if they ever happen the tools. there's a lot of catching up to date. the story and power stations apparently don't need huge amounts of, was it for cruising in front. some of the eclipse sounds had to reduce the outputs last summer because dried up the roof is meant that didn't get enough cooling goals. nuclear power provide $75.00 to cents a front is electricity. on the 1st waste repository is being found in the countries know this drilling as an experiment that's been going on for more than 20 years. every day builders

reset chosen scientists come down here in east the french village of who are in lorraine. they want to know what the rope will hold for at least the next 100000 years. amelia is a geologist and the boss here. she takes us 500 meters down to her underground rock labeau to treat the repository for more than 85000 cubic meters of radioactive waste is to be built a few kilometers from here already. the research lab is huge, stretching over to kilometers of tunnels. census monitors, things like the rock is moving. uh, 6. okay. so we want to find out how the different materials behave over time. with simulating the effects of degradation and this bull home to the tribunal, 13 years ago, we lowered a gloss matrix into the wrong because it's one of the materials used in containers of highly radioactive waste. with whom do i put addition to what action is it?

the most dangerous highly radioactive waste relates to be transported even deeper into the rock in steel containers like these control but robots, through micro tunnels. the final reports of trees built to have all the highly radioactive waste in front of the well. and then going, as you can see, this clay rock has great properties for on need. so i said look disc, that's extremely fine. it surfaces homogenous and does hockey pores, the tools so it doesn't look good strain too bad to disrupt is practically impossible. that you test, so the quantity is always on said hush. but the media is these grand project might still fail. she still waiting for official approval for the radioactive waste to be stored in this rock. but construction is scheduled to start in 5 years. the 1st

containers would go into storage in 2050 above ground. the facility is far less spectacular. it's located in a sparsely populated area, about 300 kilometers east of paris. it's peaceful with hardly any one on the roads, but things are getting turbulent in this quiet village. this site tells the repository where it can go in no uncertain terms. and that nuclear energy is out in this building has become the hopes of resistance activists from all over you to move in and out. but right now it's quiet and we can get an interview. the protesters often appear in the media. here they are last summer. it's a determines group, but small in comparison to the on to nuclear movement in neighboring germany and media do they is aware that the germans do things differently. they might, yes, as,

as well. and that's how the gemini has made it decisions on energy policy. what's on a scientific level, we're still working together. and germany is also looking for a suitable nuclear waste site quickly. after all radioactive waste won't just disappear, permanent storage solution needs to be fine. no. this will. so a question of responsibility that we don't just post the problem if nuclear waste on to future generations. that's why we can say with what we know today with 30 years experience investigating the underground truck here that the plans were posit, treat as the safest and by sustainable solutions the government is likely to green light the project, not least because of a lack of alternatives. in this regard, frances way ahead of germany, where the search for a permanent repository will take several more decades now

to x rays, they have the electromagnetic waves produced by x ray tubes with the help of negatively charged particles called electronics. if electronics are accelerated using high voltage and smashed into an obstacle to 7 diesel ration, produces energy in the form of x rays, and they were discovered 128. he is a nice underwrites 18. 95 physicist vill holding. conrad went and made a monumental discovery. while experimenting with cafe cheats in his lap, he discovered a right that could penetrate human tissue and reveal the inside of the building. an x ray image of his wife baptist home does the 1st documented example if this miraculous new technology, the vin skins, discovery close to sensation and the scientific community and revolutionize the

field of medicine. radiologist, thorsten blay, from the university clinical, pittsburgh, and germany explains some stuff. the funds are for the scientists were immediately excited. they recognized right away that this technology would be invaluable for the medical field, especially for showing broken bones and bone disease. soon afterwards, it was also used to identify soft tissue disorders in the chest and stomach areas on the x ray technology allowed doctors to make diagnoses and treatments that were previously impossible. the harmful effects of x rays was seen identified as well. and then use for radiation treatment of counts a into about 2 laces generations of research has continued to explore the various uses of x rays due to advances and medical imaging and computer technology. another milestone was achieved organs could be observed in 3 d. thanks to off official

intelligence computer tomography or c t keeps getting back to, to complete the seats position. so satisfied it to you has come so far that the resolution of the images we create keeps getting higher and we need less examination, trying to make them to the images of moving structures like the cardinality activities around the hearts which are small and moved by breathing and the pulses can also be generated by the light to c. t generation now totally produces better images. it will say provides more protection from radiation, which is back to us. the patient's house was x ray technology is not just used for medical purposes. it also helps to check passengers look at to type ports to ensure no dangerous items of smuggle through x rays play a vital role in the world of o 2 by helping to support full juries in archaeology. x rays and use to more

precisely examined ancient fines like mummies, without damaging them at the found holes, the institutes and the german city of pruitt x rays are used in a multitude of ways such as to inspect construction materials on companies, dogs by speed, your thoughts like central high x ray technology can also be used to make vehicle safer. i could use our senior longer for a long time. no, we've used x rays on, for example, is called o u many and construction materials to check them for defects. so that when they are installed in the vehicles are there and possibly we can guarantee safety on the road and guide or 3rd calls or developments with extra large c t systems can even scan entire vehicles. the x rays are also used on prompts. flower pots in green houses are scanned help

document conch grace. the technology can monitor how close react to heat some dryness, which makes it easier to select certain ones for breeding. now it's even possible to x ray entire wheat fields. the you're found on windows, i'm faithful thought of you and then we drive across the testing fields with our field robots as we call it star, and not to find or pick tables from there, we can get the relatively objective picture to the girl and see about how much a particular crop bill you are given, call me on how fast the gross will be. the smartphone integration is x ray. technology is used expansively and its development continues. is what else in finding the far from creating more x rays in shortening measurement times will definitely be a focus of research in the future. so that's with paul to collect sound the rates has come in here. electronics reach almost light speed and produce up to 70000 x

ray laser flashes past seconds. reset just from all over the world to use these especially intense x rays for a wide variety of experiments that could help shape the feature, the now to a positive acceleration way, researches conducting x ray experiments. daisy is essential to natural science reset and have that. they, they work with stuck to is out, and then their level be able to develop new processes and products placed on images . they all come in. now this is a solar cell or to be precise, spray on solar cell that could revolutionize solar technology. it's made of cellulose, nono crystal substrates with a fenn, pull them or membrane. here at the daisy research center in germany. you quickly

ask yourself why you didn't pay more attention in school physics lessons. but let start simply, wait, are we present to you in the we are here in the beam line of the pitcher 3 beam line, p 031 we're synchrotron. x rays are used to them. that doesn't help so much. but let's keep going to use trucks to cope has been working at the daisy for some 13 years and his team takes care of measurements. so what exactly is being measured here? and what does the famous 2.3 kilometer long particle accelerator has to do with it? let me go and wish you know the accelerator itself on because the name suggests accelerates the particles which preceded the traveling almost the speed of light. and when they passed through a magnetic field and a sort of change their trajectory of a vehicle and lose energy in the form of x rays on the way the team could then use

this x ray radiation to precisely determine the structure of various objects. but why is that helpful? those kind of pushing, it can play a role in a number of everyday things. i'd be a chocolate or a solar cells or implants or muscle research. so we put a variety of objects in the x ray beam and okay, unit height, the beam comes from there that hits this object and is scattered. and we have various detectors that capture the light and on the basis of the pattern that emerges on these image was what stuff? well, we can model what happened at the nano level. so what can i can to what i'm, what in the human bustle, phenomenal, even the policy of this diesel to you, it looks it too hard. it's narrower, here, and wide are here. and the detector has also been tilted here. what's the assess being fascinated by the natural sciences since he was a child. he studied chemistry and that his ph. d. a daisy know kind of us con.

in the into see if and i'm very interested in the process as of nature and want to watch nature at work and understand what goes on. and that's why i'm fascinated by and passionate about working with these beams. always like to really gain new insights back to the liquid solar cell in a few years. we may be able to spray it on his walls and planes. almost all. we also hope, of course, that it will have an influence on research and development in the industry, and that in the end, it will be cheaper or better for all of us. so that solar cells last longer and don't have to be replaced. as fascinating as the complex these nano particles, the daisy encumbered could change the world. let us read. why do you have a science related question?

5 video protections, social it's may 6. if we need to your question and i'll show, we'll send you a little surprise as the thanks you. come on. just on this week, it asked me chavez, from mexico, wants to know the how much much disassemble is per 2nd. and how much energy does it generate? oh, son is a huge pool of electrically charged guns, ultraviolet lights and x rays show up vast plasma field loops along its magnetic field lines. we'd have to place the side by side more than a 100 times to reach the diameter of the sun. in comparison to our home start and the elements will forces the range. uh the earth is tiny, almost unknown entities deep inside just it's called the energy is

generated that makes the sunshine air with a temperature of 15000000 degrees celsius. and under a numerous pressure, hydrogen atoms are fused to form helium. it takes around a 100000 years for the resulting radiation to reach the sun surface. every 2nd, all home stuck in that school 1000000 tons of money to into energy for the sun, a may a trifle full 1000000 times. that's the weight of 10000 fully occupied long distance planes. the, the sun also loses mass through the cycle. solar wind. the constantly fleming stream of particles, flows through our entire solar system, creating a protective bubble. it makes the sun one telling us not to pass that can go into

it releases as much energy in a single 2nd as we own us use and a 1000000. yes. that's what formula show that. we find it hard to imagine the only a small percentage of this energy reaches promise us, because the lights intensity decreases as a distance of sun is only half way through. it's like spawn it will supply our planet with some lights for another 4 and a half 1000000000 years. however, it will only lose a 1000. so if it's mass during its unimaginably long existence, once it's been tough, it's hydrogen. the sun will turn into a so called red giant, becoming huge heat, bloated, and harling 10 to 20 percent of its mass into space. then it will have reached the end of its life, as we know,

it will already of time the us into a hold that to finance the that was this week's episode of tomorrow today, whether you've been watching on your phone or tablet or tv, we have you enjoyed the show, see you next time. state curious by the
