so long!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's pretty awesome !!!!!!!!!!!!!!!!!!!!!!!!!!!

If i get through this the world will be in considerable danger....

o watch from18:00 mins to 25:00 in the first video

It depends from 25 years to 75 years for plutonium warheads . most of the warheads designed in 1980s were 25 to 35 years shell life but India has used supercomputers to design its warheads its plutonium pits there are many materials in a nuclear weapon, including metals, high explosives, polymers, and ceramics. The aging of any one of these materials could affect weapon performance, which is why Indian scientists with a wide range of materials expertise are working to understand aging processes.
Using complex differential equations and probability we can recreate blasts in our supercomputers which India does and design long lasting warheads.
Oxidation is a general problem of components of warheads , plus is boosted fission warheads which uses tritium gas to boost warheads has a half life of about 12.5 years so tritium gas needs to be changed but India produces world's largest amount of tritium thanks to our heavy water reactors.

You certainly know quite a few things so can you tell why we haven't gone for MSR for third stage?

I watched it... its interesting... Fission- Fusion -Fusion -Fission Boom

@Rowdy have you watched these, all through?

yup.....................................................

yup.....................................................

Do they mention anything about some sort of physical part or partition between the Primary and Secondary? I am not asking about the physical separation of the two by keeping them apart. I wish to know if there is something physical as a partition.

And if they do then what purpose do they say it serves?

These vids are too long and the connection is not very fast either.

OK ...
You definetly want to watch the first video then.... The second one is about enrichment
They discuss the explosion in a spherical "crush" bomb and discuss the complete physical design thereof (begins at 18:00 min till 28 min) including the fission fusion thermonuclear bomb. They do discuss the materials ... the professor begins with a sphere of HE-Pu and "evolves" the design explaining the evolution and the functions.
Then they discuss modern bombs which you have asked (with a neutron generator ... at 29:00 min )
HE DID NOT DISCUSS HOW THE ENERGY FROM PRIMARY WAS FOCUSED ON SECONDARY (he just mentions that the pressure was generated from photons from the primary)
I recommend you watch it from these timestamps.

Here is a smaller video

India is already designing liquid fuelled MSR known by the name Indian Molten Salt Breeder Reactor (IMSBR) great research is been done for a fuel cycle with high breeding ratio , India is still experimenting with types of liquid molten salts and ways of refueling the reactor with online refueling or batch refueling , online refueling is a tough nut to crack but Indian scientists can do it . It is still in research stage

Hmmmm..............I haven't been following up with ITSNP but this is good news. Really good. Hope we can beat Chinks to it, although it will be difficult. They've got help from the ORNL people and maybe even designs.

whenever we extract plutonium out of the spent fuel from reactors which have run normally not on low burn up we get plutonium which has both Pu 239 and Pu 240 if the Pu 240 in the mixture is more than 19 % it is reactor grade between 5 to 18 % it is fuel grade Plutonium but if we run our reactors on Low burn up and extract the Plutonium which has 95 % PU 239 and only 5 % Pu 240 that is weapons grade .
You see Pu 240 is not good bomb material as the blast would fizzle so we want as less Pu 240 and more Pu 239 to make bombs.
Always Pu 239 and Pu 240 appears simultaneously the trick is to run the reactor such that fuel is not completely extracted of energy you can have super weapons grade plutonium . But running reactors on low burn up is not feasible otherwise everybody would have made bombs . But Heavy water reactors can pull of that stunt which by the way India has 8 outside safe guards .
Theoretically we can produce 700 to 1000 kg of weapons grade plutonium if we run the reactors at low burnup which is sufficient for 250 to 350 nuclear warheads per year but we require 3 tonnes of uranium ore to do that and we only generate 1200 kgs per year and the reactors would not generate much electricity. But 1 to 2 reactors can be run on low burnup enough for 80 to 100 warheads per year. it depends upon the govt and we need to have enough reprocessing capability .

Actually i made a slight mistake in quantities by typing hurriedly instead of 3 tonnes it is 3000 tonnes of Uranium and our total annual production is not 1200 kgs but 1200 tonnes

We can also work with ORNL people after the nuclear deal we shouldn't have problem working with Americans or for that matter anyone.

This fast breeder reactor reactor has a doubling time of about 13 years that means it can double the plutonium which the core is made up off in its radial and axial blankets of uranium into Pu 239.
If India decides to make it complete military use it will generate 140 to 150 kgs weapons grade Plutonium per year which is 95 % and above Pu 239 and less than 5 % Pu 240.
That means we can produce 35 to 40 warheads per year just from this reactor provided reprocessing facilities is there.
or
in other words
1 Fast breeder reactor = 2 x ( Pakistan's complete nuclear weapons program)
We also have 8 heavy water reactors with online refuelling capability in our military program.

There are 12 reactors planned for the future ;all on the military side. I remember a high ranking indian official saying india in a few years india would have enough plutonium for 700 or more warheads annually . This is where he was getting the number from.

 

[Mad Indian]

@Mad Indian should be happy with all the power generation facility in TN!!

Hardly dude. Only half of the power generation is for TN. So we need at least 40k-50k MW of nuclear power generation in TN ideally over the next two decades since we will get only 20k MW from that. I think the current proposals are for about 12k-15k MW of nuclear power generation over the next 2 decades. It's nothing compared to the projected power requirements

For that we need huge quantities of plutonium like around 1.98 tonnes for each reactor which means around 23.76 tonnes plutonium over the next 15 years , we have around 10 to 12 tonnes of unsafeguarded plutonium and we make 1.4 tonnes annually from our unsafeguarded reactors so we need more heavy water reactors and far more reprocessing capacity for that expansion atleast another 500 to 800 tonnes annually over the next 5 years.
France had a similar breeder reactor for 15 years and and it has worlds 3rd largest nuclear weapons program imagine if if only half a dozen breeders come online in India

 

[LETHALFORCE]

Aside from weapons programs plutonium maybe the fuel for spaceships in the future.
