Zirconium alloy
Zirconium alloys are solid solutions of zirconium or other metals, a common subgroup having the trade mark Zircaloy. Zirconium has very low absorption cross-section of thermal neutrons, high hardness, ductility and corrosion resistance. One of the main uses of zirconium alloys is in nuclear technology, as cladding of fuel rods in nuclear reactors, especially water reactors. A typical composition of nuclear-grade zirconium alloys is more than 95 weight percent zirconium and less than 2% of tin, niobium, iron, chromium, nickel and other metals, which are added to improve mechanical properties and corrosion resistance.
The water cooling of reactor zirconium alloys elevates requirement for their resistance to oxidation-related nodular corrosion. Furthermore, oxidative reaction of zirconium with water releases hydrogen gas, which partly diffuses into the alloy and forms zirconium hydrides. The hydrides are less dense and are weaker mechanically than the alloy; their formation results in blistering and cracking of the cladding – a phenomenon known as hydrogen embrittlement.

In Your Eyes
by: Sarah KellySweet Illusion knows my name
Take a breath and run away
Never ending to pretending
To escape the pain
Honesty please come to me
Humbly I've found my knees
I am blind but I want to see
Come now truth and find me
In your eyes
I see for the very first time
In this light
I feel and I know I'm alive
No need to entertain the game
On the streets of empty fame
No sufficing too enticing
No one left to blame
But honesty has come to me
Freedom found down on my knees
I was blind but now I can see
Truth has finally come to me
In your eyes
I see for the very first time
In the light
I feel and I know I'm alive
I'll wake up any moment now
It's so hard to believe that the traitor is me
Love is breaking through the night somehow
Not as real as it seems, here inside of this dream
In your eyes
I see for the very first time
In the light
I feelâ¦l and I know I'm alive
And in your eyes
I see for the very first time
In the light
