Fusion power seeks super steels

Fusion power seeks super steels

Jet (EFDA)

The JET lab has helped pioneer fusion

Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors.

New research shows how steel will fail at high temperatures because of the magnetic properties of the metal.

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 where temperatures would be in a similar range to those experienced in the Twin Towers’ fires.

‘Not melting’

The key advance is the understanding that, at high temperatures, tiny irregularities in a steel’s structure can disrupt its internal magnetic fields, making the rigid metal soft.

“Steels melt at about 1,150C (2,102F), but lose strength at much lower temperatures,” explained Dr Sergei Dudarev, principal scientist at the United Kingdom Atomic Energy Authority (UKAEA).

Iron atoms in steel: Black balls show irregularities that disrupt magnetic fields, weakening steel

At room temperature, the magnetic fields between iron atoms remain regular, but when heated, these fields are altered allowing the atoms to slide past each other, weakening the steel.

“[The steel] becomes very soft. It is not melting but the effect is the same,” said Dr Dudarev.

He said blacksmiths had exploited this property for hundreds of years – it allows iron to become pliable at temperatures much lower than its melting point.

The peak in this pliability is at 911.5C, but begins at much lower temperatures, at around 500C (932F) – a temperature often reached during building fires.

The steel backbone of the Twin Towers was probably exposed to temperatures close to this, when insulating panels – meant to protect the buildings’ structural frame – were dislodged by the impacts of the hijacked planes.

The roaring fire mid-way up the building heated the steel struts, and once temperatures rose above 500C the structure became elastic, and collapsed under the force of the floors above.

Tuning up

The interest of Dr Dudarev and the UKAEA is to find steels that can withstand the intense heat of being inside a a fusion reactor.

UKAEA has helped pioneer fusion power – deriving energy by forcing together atomic nuclei – at Europe’s JET lab in Oxfordshire; and is now assisting the development work on the world first large-scale experimental reactor known as Iter.

The extended periods over which Iter will run means the reactor must have robust materials built into the vessel where the fusion reactions will occur.

Dr Dudarev said it should be possible to tune the properties of suitable new steels by adding a mix of other elements.

“We need to look at the magnetic properties of steel, [and] vary their chemical composition in a systematic way in order to get rid of this behaviour,” he suggests.


  1. hope this puts to rest all the noise from the insane truthers. God Bless George Bush!

  2. Hahahaha, I know now that this is going down in history as the point at which science and anyone who understands science DIED, you fucking morons, how the FUCK can you take this tripe from some arsehole who is on your payroll, (taxpayer funded researcher) because he is a THIEF, they are RAPING YOU, you have no concept, he has invented a whole new phenomena with out ONE PAPER BEING PUBLISHED AND PEER REVIEWED – God bless dickheads like you that read this and take it seriously.

    And moreover, fusion reactors will never use steel!!! hahahahah oh god, so funny, hahahahah, and if it did, it would not be woried about strenght??! Million degree temps don’t care about strength!!! Oh god, why bother fusion reactors are a fantasy, and can NEVER be a reality, hahahaha, you dickheads, you are pathetic children.

    Also, the dickhead says blacksmiths ahave exploited his ‘discovery’ (ohh you deserve a Nobel mate!) but the twin towers were not struck repeatedly, nor were they progressively put into a SUPER HOT fire, the jet fuel was NOT concentrated, it was poorly fed, it was a COOL fire, and it did NOT get to Mid way up the building, what is he on???

  3. where can I get funding for my easter bunny ,frosty the snow man mini black hole fusion reactor?
    i ony need 2 billion.

    BTW,lokis a friend of mine,knows a fireman at the twin towers,who heard the bombs going off.(AND THEY WERE BOMBS HE SAID-)
    check out tsarion and maxwell jordan,interviewed on coast to coast am.the towers were 1st-a luceferian ritual to inagurate the final phase of the nwo(the towers were buit for this,its magick)
    the illumaniti plan to sacrifice the majority of the usa(200 million)
    but the creater of the universe,the real grand archetich,jehovah has a surprise for them.

  4. A simple experiment with a poker in a wood fire will show how quickly steel loses its strength before becoming even red hot. Most steel/concrete buildings have several inches of concrete over the steel to protect it from fire, the Twin Towers did not, only sprayed on compound that was deemed insufficient at a later stage and was only corrected in part in one building. In addition, there was aluminum cladding next to the steel that was corroded by electrolytic action that eroded the high tension steel bolts, some were drilled out in the lower floors and replaced but the noise of drilling caused the process to be halted. The products of corrosion are aluminum oxide and iron oxide, the components of Thermite, once ignited this burns at a temperature above the melting point of steel. Any text on the failure of high strength materials will show that it occurs explosively, hence the reduction of concrete to dust. Once one floor failed, the hammer blow of 40,000 tons plus of the structure above falling ten feet was enough to start the almost free fall with air pressure blowing out fixed windows like explosions.
    Sorry to put a damper on the conspiracy delusions.
