11:30 pm
instruments on great stages the world over we catch up with him in his adopted home early in your room. 2 13 for winning offer if he's available world wide and for every language level, learning german has never been simpler german to go, the vc 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 any states, the body luggage costs penetration rise into their atomic structure. but what
11:31 pm
do they pose for that in more coming up the kind of with welcome to tomorrow. today the site is kind of then when it comes to nuclear power, it all depends on the rest of nuclear power, produces aggressive radioactive waste. but what is, instead of uranium? we were to use the methyl story and waste from story and power station supposedly. and it's very ation for a much shows at times and uranium based nuclear waste. it's also supposed to be meltdown truth. but all of the claims for real, the nuclear gets a pretty bad route. and there are some good reasons for that. in the, towering much from japan, you could read it still there was
11:32 pm
a purse like union has suffered, is disasters in the history of nuclear, faster of on known for portions. but we'll see if we could help 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 you clear history? a powered 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 water was molten. and so i would call them the records from
11:33 pm
studying success. it did things and in the 1960s that we still can't do in reactors today, took sorenson as a self proclaimed story. and if i'm journalist his company, slide, energy is working on a modern version of the oak ridge 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, but it was originally put forward by often wineburgh at oak ridge national lab and 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 uranium 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,
11:34 pm
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 absorbs tons, attends authority into 3 tree. no chain reaction yet, because after about 20 minutes or so, it decays into po, tucked 10 am to $33.00, which after about a month, the case into uranium 233. i thought those meant so the system, the intense need to stop the top. if you like a, a, a bit of a 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
11:35 pm
soul can serve as space of fuel and the coolant mission of reduce costs, not turning in operation control. so in the construction of the cons that also be less radioactive waste and conventional re access and much of it would be mostly gone off to hundreds instead of thousands of years. and in floria molten salt, we act as he'd get fetch me know, pretty tiny of which could be used to build nuclear weapons. all of this really seems like molten salt. react isn't story m r a much made and having the test react to run it full. tell us more than $13000.00 and became the world's fast react to to run on uranium t $33.00 produced from florida. and then government officials pulled the plug. what happened? well, for one, the experiment didn't always run smoothly. the the experience with the martin salt reactor experienced what he meant in oak ridge was pretty big.
11:36 pm
this is an even on a assist assist to reset his nuclear 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 tell you don't fit for me about 70 percent of the time that we also have questions about the materials in touch with the liquid fuel. the low is specifically designed to which stands extreme heat corrosive salts in radioactivity, shared cracking, and other concerns with the radioactive gas by product tricky in which it already becomes each way that 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 ended was different. i preached direct to all of and one badge, right?
11:37 pm
a problem is not the term right. there is a pull. one brother, it's just different from the main line. main line met pressurized holt reactance backwards. a much better test 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 to a number of generations of nuclear reactors and other technologies we most often do . one initial generation and it's time to, to continue on and in see and understand these, these advantages that can be used into the design. china is currently testing the molten salt process and the guy does it an india home to the world's largest story
11:38 pm
and resides is also why can only access to utilize them as possible long time. you can use struct today. you know, there's one level of, of it which is sort of talking and, and saying you're going to do things. the more important aspect is to actually be doing it. and this might prove, aloha to the flushing 3 d animation suggest a multitude. so we act as really safer than conventional plots. any good resonate or would it be asking a lot of questions to a designer? how is this reactive behavior? there's a fire pointed, there's an earthquake. what is your operator press this button and stop that? but those are not easy questions to tensor to build a story and react to it 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
11:39 pm
build an entire infrastructure and supply chain from scratch. in the last couple of years, we've had more capital and we've never had before. and we proceeded much faster to be around before. but it's still a very, very small amount compared to where we need commercial story and molten. so we access, i still use a way, at least if they ever happen the tools. there's a lot of catching up today. the story and power stations apparently don't need huge amounts of loss of recruiting in phones, some new tips on how to reduce the outputs. last summer, because dried up ruth is meant they couldn't get enough cooling. both nuclear power provide 75 percent of frances electricity. and the 1st waste repository is being found in the countries, not this drilling
11:40 pm
as an experiment that's been going on for more than 20 years. every day builders reset chose, and scientists come down here that needs 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 those 500 meters down to heart underground rock, lebeau, to tree. 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. sensors monitors, things like have the rock is moving uh, 602. mm hm. so if we want to find out how the different materials behave over time, with simulating the effects of degradation and this bull home. just to review 13
11:41 pm
years ago, we lowered a gloss matrix into the wrong because it's one of the materials used in containers of highly radioactive waste. addition to what action is it, the most dangerous, highly radioactive waste will later 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 go, so you can see this clay rock has great properties for all needs. so, so the disk is extremely fine, it surfaces how much in us does hockey pores, the tools, so it doesn't let me put strain, i'm going to bed. this rock is practically impossible that it does. so the quantities always sunset hushed books. demilia is these grand project might still fail. she still waiting for official approval for the radioactive waste to be
11:42 pm
stored in this rock. but construction is scheduled to start in 5 years. the 1st containers would go into storage in 2050 of the 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 side 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't get them into view. 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
11:43 pm
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. need to be fine. no. it's also a question of responsibility that we don't just post the program 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 ponds repository is the safest and most sustainable solutions the government is likely to green light, the project, not least because of
11:44 pm
a lack of alternatives. in this regard, france is way ahead of germany, where the search for the permanent repository will take several more decades. now to x rays, they, the electro magnetic waves produced by x ray tubes with help of negatively charged particles called electronics. electronics generated using high voltage and smashed into an obstacle to 7th diesel ration, produces energy in the form of x rays, and they were discovered 128. he is when they send the rates 18. 95 physicist vill home conrad went and made a monumental discovery. while experimenting with cafe cheats in his lap, he discovered a ray 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,
11:45 pm
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, give us some stuff. the funds of thought that 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 home for the effects of x rays was seen identified as well. and then use for radiation treatment of come into the q lysis. generations of research has continued to explode, the various uses of x rays due to advances and medical imaging and computer
11:46 pm
technology. another milestone was achieved organs could be observed in 3 d. thanks to opt, official intelligence computer tomography or c t keeps getting back to, to the computer to the seats position. so set the bye to speakers on it to you has come so far that the resolution of the images we create keeps getting higher and we need a less examination thing to make them to the images of moving structures like the cardinality author. these are in the hearts which are small and moved by breathing, and the pulse can also be generated by the light to c t generation natalie produces better images. it will say provides more protection from radiation which is back to us. the patients house for sex, right? technology is not just used for medical purposes, it also helps to check passengers look at to tap ports to ensure no dangerous items
11:47 pm
of smoking through x rays play a vital role in the world of o 2. by helping to spot forgeries in archaeology, x rays and used to more precisely examined ancient fines like mummies, without damaging them at the found holes, the institutes in the german city of pruitt x rays are used in a multitude of ways such as to re inspect construction materials on companies, dogs by speed, your thoughts like since you a 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. it's called o u many and construction materials to check them for defects. so that when they're installed in the vehicles are there and possibly we can guarantee safety on the road and guide off their calls or developments for extra large c t systems can even scan in time vehicles. the x
11:48 pm
rays are also used on prompts. flower pots in greenhouse is a scanned help document. conk grace. the technology can monitor how close react to heats and dryness, which makes it easier to select certain ones for breathing. 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, it are a lot to find opiate keep us from there. we can give a relatively objective picture to the girl and see about how much a particular crop bill you log in given and how fast the growth 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 and shortening measurement times will definitely be
11:49 pm
a focus of research in the future. so that's with paul to connect sound the rates has come in, pair of electrons, 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 restrictive out and then their level the 8 to develop new processes and products placed on images as if 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
11:50 pm
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 to. but let start simply, wait are we isn't here 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 it, because the name suggests accelerates of particles which preceded the traveling almost the speed of light. and when they passed through a magnetic field and
11:51 pm
a sort of change their trajectory of a vehicle and lose energy in the form of x rays on the team can then use this x ray radiation to precisely determine the structure of various subjects. but why is that helpful? does come in for students that can play a role in a number of everyday things might be a chocolate or a solar cells or implants or muscle research. so we put a variety of objects in the x ray beam, okay. units called high beam comes from there that hits this object in his scattered table. and we have various detectors that capture the light. and on the basis of the pattern that emerges on these image was what we can model what happened at the nano level. so what can i can, what i'm, what didn't you and myself then not only in the policy of this, and he felt that you, it looks it too hard, it's narrower, here and wider 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 as pon
11:52 pm
and they've been 0. ready to 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 the house walls and blaine's home. 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
11:53 pm
read. why do you have a science related question? 5 video text social it's may 6. if we see to your question and i'll show, we'll send you a little surprise as a thank 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 bull of electrically charged guns, ultraviolet lights and x rays show up fast 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 the head start and the elements will forces the range. uh the earth is tiny,
11:54 pm
almost unknown entities deep inside just it's called the energy is generated that makes the sunshine air. it's 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 homestar combat school 1000000 tons of money to into energy for the sun. a may a trifle. 4000000 tons. 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,
11:55 pm
creating a protective bubble. it makes the sun one tell us not to pass that can go into the 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 song is only half way through. it's like spawn it will supply our planet with some light for another 4 and a half 1000000000. yes. however, it will only lose a 1000. so if it's mass during its unimaginably long existence, once it's ben tough, it's hydrogen. the sun will turn into a so called red giant, becoming huge. he bloated and handling 10 to 20 percent of its mass into space.
11:56 pm
then it will have reached the end of its life, as we know, it will already of time the us and to hold that promise 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
