Colours of the White !

On the palette of life,there are hues-Unknown,Undefined and Unaccompanied.Each representing something,doesnt matter what.There is Green,There is Red and there is Blue.And when you would think,are they the only one,Yellow would creep in,Black would roar and Pink will desire its mention.
When you debut opening your eyes in this world,Red is with you.Green defines the life to you,provides your brain coil something to hold.And When you mature,you realize that its the Blue that rules the world.It is the blue that bestows all the blues to the palette if you dont possess it.But at this moment,May I insinuate that Pink is no less in giving you sorrows.Agreed,it makes the world beautiful but its the Pink who also snatches all the beauty from the palette.
As you grow old,you gather that Red has grown old several manifolds and wishes your attention.But then Black eats up all of your time and then there are tiny lilliputian Yellow too for whom you are the Red.You cannot abandon Black,as it furnish you Blue but then other colours are no less important.In this chaos,you suddenly sometime find that its Time !
In the quest of consuming all your colours in the painting of your life,you forget that the paper was initially White.And then you discover that all colours alltogether also make up White.
They are just the Colours of the White !

Again be the King !

All that glitters is not gold
Not every day is dark and cold
Old is not always weak
He is not a fool who seeks
A hammer shatters the glass
But forges steel
It takes a strong fish
to swim against the sea.

Into the horizon will emerge a new sun
The light that faded will again burn
After autumn,it always comes the Spring
The Crownless shall again be the King !

My Guitar Gently Weeps

Flying past and remembering those last
Love filled days,
While my Guitar gently weeps.

Dont know how
I went so loud
Broke all my crossings
From then my Guitar gently weeps

How to forget
those tears you had
While I left you crying
And so my Guitar gently weeps.

Twenty years,
You not even in my dreams near
Inspite of all my tryings
Still my Guitar gently weeps

I have not
lived any day of any sort
Since when my Guitar gently weeps
Along with me !

A light Poetry I wrote in around few minutes listening to The Beatles :)

Dereliction of Nuclear Duty : A Possibility ?

Japanese Catastrophe Redux : Japan seems to have some grudges with Neutrons. After Hiroshima Nagasaki Duo, March 11-2011 is another infamous date going down into Japan’s History. A quake of 8.9 on Richter scale stuck the tech island giving rise to Tsunami. Now as if this was not enough, Nuclear breach occurred too redounding to the catastrophe. The Cooling systems failed, exposing the fuel rods to naked atmosphere causing radiation in the vicinity.

The Question then arises, Juxtaposing India and Japan, do we too stand a chance of any such breach in the future, when we have already faced some Tsunamis in the past ?


Why Nuclear Plants are mainly situated near coasts (where Tsunami threat is at peak )? All Nuclear plants require a huge supply of coolants and water for cooling purposes of Nuclear Fuel Rods. Constructing them near a coast where large mass of water is available is due to economy reasons.

Firstly, India has 8 nuclear plants(including under construction) as shown in the figure below.

India has two coast-lines. East that contains Kalpakkam Nuclear Plant,Madras and West,that boasts of Kaiga,Tarapur and Kakrapar Nuclear plants. NPCIL(Nuclear Power Corp.) maintains that no reactor should be within 5km radius of fault line while Fukushima was located directly on a fault line (No fault of planners though, Japan has too many fault lines).
Moreover, Only one of the reactors are in Zone-4 (High Probabilty of Seismic Activity Area) which is Narora .Rawatbhata,Kalpakkam and Kudankulam are in Zone-2.Tarapur,Kakrapar,Jaitapur and Kaiga in Zone-3.Though Narora is in Zone-4,We need not fear much by it coz its not near a coast (No chance of rendezvous with tsunami :D) and Reactors do not fear earthquakes (Japan’s nuclear apocalypse started when Diesel Generators and switchgears were ruined by Tsunami Waves)
Out of all Indian nuclear reactors, Kalpakkam has the highest possibility of being stuck by Earthquake + Tsunami Combo. Let us assume that in Dec.2012,there is a tsunami (much like Japan’s) targeting Kalpakkam plant. Then too,We need not fear.Reason : Difference in Design of Japan’s and India’s Reactors.

Basically,there are two types of Nuclear reactors : 1) BWR (Boiling Water Type ) and 2)PWR (Pressurized Water Reactor)
In layman language,A nuclear reactor produces heat with the help of radioactivity. This heat converts water into steam which further rotates the turbine to produce Electricity. In BWR type, The cooling water is maintained at about 75 atm so that it boils in the core at about 285 °C. In comparison, there is no significant boiling allowed in a PWR-type because of the high pressure maintained in its primary loop—approximately 158 atm.
Thus a BWR-type requires a more powerful cooling system. It requires active cooling for a period of several hours to several days following shutdown.At an event of an earthquake,the nuclear reaction is automatically stopped. However, radioactive decay of the fission products in the fuel will continue to actively generate decay heat at a gradually decreasing rate. If active cooling fails during this period, the reactor can still overheat to a temperature high enough that zirconium in the fuel cladding will react with water and steam, producing hydrogen gas. In this event there is a high danger of hydrogen explosions, threatening structural damage to the reactor and/or associated safety systems and/or the exposure of highly radioactive spent fuel rods that may be stored in the reactor building as happened with the Fukushima I nuclear accidents.
In PWR-type there is no such problem. It runs cool. In contrast to a boiling water reactor, pressure in the primary coolant loop prevents the water from boiling within the reactor. So containment of Heat is relatively easier in this case. And so nuclear breach not a problem.
As India employs PWR-type nuclear reactors (Only Tarapur being BWR-type),we do not face any immediate nuclear doomsday like Japan :)
But still there are some Civil Engg. Factors involved that needs to be looked upon too. I,along with some friends, am working on it and will come up with the analysis soon.
