'Super Steel' Sought For Fusion Reactors

Smivs writes "New research shows how steel will fail at high temperatures because of the magnetic properties of the metal. Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors. The New York buildings fell when their steel backbones lost strength in the fires that followed the plane impacts. Dr Sergei Dudarev told the British Association Science Festival that improved steels were now being sought. The principal scientist at the United Kingdom Atomic Energy Authority (UKAEA) said one of the first applications for these better performing metals would be in the wall linings of fusion reactors."

      If the jet fuel is out in the open, where heat can dissipate, that would be true.

If the energy cant escape, it builds up in the form of heat.

The solution is a more robust and adhesive fire coating (like foam bead containing cement with polymer binders added to the liquid portion) and redundant sprinkler stacks.

      Heavy timber and large engineered wood members generally do survive fires better than steel, at least from a structural sense. The beams can burn, but wood is a pretty good insulator, so while the outside of the beam might be charred black, there's still plenty of sound material left in the middle to hold the building up. Structure in buildings are generally specified with a very large safety margin. There's more than enough wood there so that you can afford to lose some of it to a fire. Steel, on the other hand, conducts heat very well, and so the heat required to weaken it moves throughout the member quickly. The fire doesn't have to work through the steel to weaken it, it can basically attack it all the way through all at once.

      I've been in a number of buildings in the french quater in new orleans that are over 100 years old, and which have been through a number of fires. Many of those buildings contain beams that are black with char all around, but have continued to support their roof for decades.

      There are a lot of reasons why steel is used instead of wood. There are many ways to protect steel from fire damage, and even with those measures, steel will often be significantly cheaper than wood. There's often a lot more flexibility with steel, as you can get a far wider variety of shapes than wood.

      And just FYI, building structure is designed by structural engineers, who generally come across as pretty intelligent. Mechanical engineers (in building design at least) design HVAC, electrical, and plumbing systems. Overall, I've been far less impressed with their skill and enthusiasm compared to structural engineers.

      There have been accounts of witnesses, firefighters included that heard loud explosions in the second tower BEFORE the aircraft hit it. Thing is, people now ignore them and call them crack addicts and conspiracy nuts.

      Where are the links to these accounts, such as where these people were standing. For example if I was stood in the lobby of the WTC when the first plane hit is it possible that I feel the impact or see a fireball shoot into the lobby before I see debris or even the noise from outside? Also explain why explosions would be going off before the planes hit and why video records do not show these explosions.

      Well, the fact that nobody was allowed to LOOK for evidence in ground zero while they were hurriedly cleaning the thing up can be blamed partially for it. But there were abnormally high temperature spots that indicated the presence of molten metal, such as produced by thermite steel cutting devices, long after the towers crashed. That was also ignored by the Commission.

      Please link to some reputable scientist or other person of standing complaining that they approached the New York port authority or whoever and were denied the opportunity to conduct their own investigation.

      Also explain why you've flipped from high explosives to thermite. Also explain what magic thermite this is that you believe continues to give off energy long after the towers crashed. Could it just be that a pile of combustible materials packed in rubble can burn for a very long time?

      And don't group people who ask tough questions about 9/11 and holocaust deniers, I am not one and resent such dishonest sensationalist comparisons which have no value in an argument. Aren't you convinced of your explanation? No reason not to keep it classy, right?

      Why not? 9/11 "truthers", creationists, holocaust deniers, flat earthers, moon hoaxers etc. all use extremely similar tactics to promote their "theories". Quite possibly because their "theories" consist of denying the conventional explanation rather than advancing a viable alternate explanation.

      The article seems to ignore the fact that engineers see steel becoming weaker with heat as a benefit. If steel was always super strong at any temperature, how would you make anything out of it? Engineers currently utilize the "irregularities" (we call them dislocations) in steel to manufacture things. One such process is known as work hardening. When certain materials, like steel, are formed (bent, rolled, etc.) at low temperature, the dislocations propagate and move. The dislocations interact with each other, like tangling up a ball of yarn, making the material stronger. The component can then be heated to make further manufacturing easier, or left in it's cold worked state to make the finished part stronger. This property of steel is utilized around the world to make very strong, and inexpensive parts. A variety of other heat treatments are available to perform similar tasks.

      In summary, the thermal properties of steel are considered a asset, because it allows us to manufacture things with high strength inexpensively. Using a material that is strong at all temperatures will increase costs. Such materials do exist but steel isn't one of them.

      What you say is largely true, but for nuclear applications you usually have a few more constraints that make steel look more attractive again.

      The core of a fast breeder reactor, or the structural components of a fusion reactor, will unavoidably be exposed to a very intense flux of high energy neutrons. These neutrons can cause all kinds of defects in the material you use, ranging from dislocating atoms to changing their elements due to nuclear transmutations, and whatever material you use must be able to withstand the irradiation. Many nickel alloys fail for this reason.

      Also any material which absorbs a lot of neutrons, or reduces their energy, is going to cause issues. If you use Nitrogen in a ceramic it may need to be enriched to prevent excessive Carbon-14 production as an example. Some elements, like Lithium, Cobalt and Bismuth, produce very troublesome radioactive isotopes when irradiated. Carbon is quite good, and carbon based ceramics are heavily researched, but it is a rather light nucleus, and will slow neutrons that scatter against it. This may be desirable in a thermal reactor, but for fusion reactors and fast breeder reactors you want a very high neutron energy to enable the destruction of long lived waste isotopes, and this means you need to limit the amount of carbon present in your core and structural materials.

      Furthermore materials to be used for a reactor need to go through very time consuming and thorough testing program , and this is why steels are very attractive candidates since much of the necessary data already exists. Sure, using something like Silicon Carbide may be worth investigating ( and it is indeed being investigated for a number or reactor designs ) , but even thou it has good thermal conductivity, corrosion resistance and thermal stability, it is not immediately clear that it will withstand the radiation environment, it's fracture hardness is less than ideal, and you need to be able to reliably produce it to the strict standards required by the nuclear industry. To develop and test a material for nuclear applications is a very expensive procedure, so if you can use materials that you already have data for, it will dramatically reduce the necessary research and development costs.

      Also, as usual there is a cost issue of the material itself. Tungsten, with its high melting point, good strength at elevated temperatures, and low neutron absorption is very attractive from technological aspects, but building an entire reactor from it will hurt your bank account.

      The Idiocy Behind the '9/11 Truth' Movement
      By Matt Taibbi, RollingStone.com
      Posted on September 26, 2006, Printed on September 11, 2008
      http://www.alternet.org/story/42181/

      A few weeks ago I wrote a column on the anniversary of 9/11 that offhandedly dismissed 9/11 conspiracy theorists as "clinically insane." I expected a little bit of heat in response, but nothing could have prepared me for the deluge of fuck-you mail that I actually got. Apparently every third person in the United States thinks George Bush was behind the 9/11 attacks.

      " You're just another MSM-whore left gatekeeper paid off by corporate America," said one writer. "What you do isn't journalism at all, you dick," said another. "You're the one who's clinically insane," barked a third, before educating me on the supposed anomalies of physics involved with the collapse of WTC-7.

      I have two basic gripes with the 9/11 Truth movement. The first is that it gives supporters of Bush an excuse to dismiss critics of this administration. I have no doubt that every time one of those Loose Change dickwads opens his mouth, a Republican somewhere picks up five votes. In fact, if there were any conspiracy here, I'd be far more inclined to believe that this whole movement was cooked up by Karl Rove as a kind of mass cyber-provocation, along the lines of Gordon Liddy hiring hippie peace protesters to piss in the lobbies of hotels where campaign reporters were staying.

      Secondly, it's bad enough that people in this country think Tim Lahaye is a prophet and Sean Hannity is an objective newsman. But if large numbers of people in this country can swallow 9/11 conspiracy theory without puking, all hope is lost. Our best hope is that the Japanese take pity on us and allow us to serve as industrial slaves in their future empire, farming sushi rice and assembling robot toys.

      I don't have the space here to address every single reason why 9/11 conspiracy theory is so shamefully stupid, so I'll have to be content with just one point: 9/11 Truth is the lowest form of conspiracy theory, because it doesn't offer an affirmative theory of the crime.

      Forget for a minute all those internet tales about inexplicable skyscraper fires, strange holes in the ground at Shanksville, and mysterious flight manifestoes. What is the theory of the crime, according to the 9/11 Truth movement?

      Strikingly, there is no obvious answer to that question, since for all the many articles about "Able Danger" and the witnesses who heard explosions at Ground Zero, there is not -- at least not that I could find -- a single document anywhere that lays out a single, concrete theory of what happened, who ordered what and when they ordered it, and why. There obviously is such a theory, but it has to be pieced together by implication, by paying attention to the various assertions of 9/11 lore (the towers were mined, the Pentagon was really hit by a cruise missile, etc.) and then assembling them later on into one single story. But the funny thing is, when you put together all of those disparate theories, you get the dumbest story since Roman Polanski's Pirates.

      The specifics vary, but the basic gist of what They Say Happened goes something like this:

      A group of power-hungry neocons, led by Dick Cheney, Paul Wolfowitz, Bush and others and organizationally represented by groups like the Project for a New American Century, seeks to bring about a "Pearl-Harbor-like event" that would accelerate a rightist revolution, laying the political foundation for invasions of Afghanistan and Iraq.

ITER is going to have (at the moment) beryllium tiles for most of the interior, with a smattering of tungsten and graphite in key locations. More cutting edge research is looking into using liquid lithium, which I think is very promising (I'm biased).

      Impurities are the name of the game. We want to dump energy into the fuel, deuterium and tritium, not into whatever comes off the first wall. Refractory materials have lower sputtering coefficients, so less impurities enter the plasma, *but* plasmas a very intolerant of high-z impurities. So the lower the atomic number, the better. High-Z materials have a lot more electrons to ionize, so you end up just dumping all your energy into the impurities and letting it radiate away instead of getting your D+T up to 10's of keV in temperature.

Long story short: polymer composites are great for a lot of things, but high-temperature applications definitely do not fall into that category.

      I do agree with a previous post I saw which suggests engineered ceramics. Ceramics are very good refractory materials, as they retain much more strength and oxidation resistance at high temperatures than steel, or for that matter, nearly all metals. They're also most likely going to be much, much cheaper than any metal engineered for this application. Steel doesn't fit the bill yet, and it would probably take a lot of research to figure out new heat-treatment methods to get it there.

I'm actually a materials engineering major in Ames and I'm specializing in polymers and ceramics (metals too at the moment, but we'll see how that goes) so I was kind of interested in specialized applications like this, and especially if everything I'm being told is wrong.

      I'm still having trouble believing a polymer that holds up to more than a thousand degrees Celsius, but it wouldn't be the first time something slipped me by. I would think a polymer with any kind of strength at 2000-3000 C would be one of the first things we would hear about because there would just be so many applications (the first thing I though of when I heard you say that was that they could definitely use fan blades for the jet turbines with those properties in polymers - ceramics are weak in tension and refractory metals that would lend themselves to this application are ungodly expensive).

      I know that some allotropes of carbon will do go that hot (like graphite and diamond), but carbon chains and networks with hydrogen and other functional groups tend not to have the greatest bond strength and some ability to move past each other, reducing melting point below those levels. My old Callister book even gives a melting temperature of 640 C for aramid fibers. These are things like Kevlar and are usually what people mean when they say "carbon fiber". I've seen people use a process like the one you described to lay up composite panels, they refer to it as "prepreg" since the resin is pre-impregnated in the fibers. Sure is a lot easier than laying them up by hand. But I'm pretty sure they never took them above 500 except to see when stuff would burn off in a TGA analysis or something. With the right material, you could probably mitigate thermal effects by drawing it away with the right thermal conductivity, but I would bet money you were using a ceramic to take the brunt of the heat if it got as hot as you said. I could see you cooking with an aramid composite, but much hotter and you'd essentially be able to, for example, melt and pour aluminum in a plastic bowl. I just can't see that happening right now.

    ALL perpetrators for any crime realize they can dissuade law enforcement by involving innocent victims in their retreat. your intellectual dishonesty or intellectual misperception is that it is law enforcement involving innocent people in the captruing of perpetrators. no, it is the perpetrator who surrounds himself with innocents in order to escape capture

    so law enforcement continually, on a real time basis, needs to make snap judgments that take into account the relative risk of harming innocents in capturing a perpetrator, versus the amount of manpower required to do so, versus the the heinousness of the crime that demands action or not. its all one humongous grey area with a ton of moral hazard with potential horrible consequences. its not easy at all, and mistakes WILL be made. welcome to the world of law enforcement

    this is real life. your scenario is not weird, it is every day. and the answer to your scenario?: get used to it. there is no answer to your scenario other than: yes, innocent people are often, and will always continue to be harmed in the capture of criminals in this world. forever

    if to you this seems cold and callous, consider that letting perpetrators of crimes off without any justice is even worse for this world

    furthermore, you need to recognize that is the perpetrator that involves innocents in his capture, not law enforcement

    deal with it. this constant jeopardy is the way the entire world works. its not pretty

      You describe some moral dilemmas, certainly. But none of them are akin to the invasion of Iraq.

      Nice try at a straw man.

      These matters are considerably more complicated when there are issues of sovereignty. I know you and many Americans don't understand that -- we (the British) used not to either, so I can identify with that: it comes with the territory of thinking your empire is different from the ones that came before it.

      Oh, I see. When you said "[Bush] certainly mistakenly kills civilians with his policies, certainly. and for this there is remorse and attempt at restitution", I thought you meant remorse from Bush.

      Also, there's a big difference between a report of someone saying sorry, and them being sorry. Actions speak louder than words.
