India to Build 6 Nuclear-Powered Submarines - Navy Chief

[Harisudan]

yes we can.Typhoon class had 2 190 MW reactors,but that was a titan,weighing 26000+ ton.

Dude Typhoon classes were Freaking monsters.. The very name Typhoon created nightmares in American Navy during coldwar.. Typhoon class weighs more than 42,000 tons displaced weight..

 

[DRDO KALI 10000]

Guess which one we are getting?

1. Virginia Class, United States

Is that actually on? I know that DRDO had completed work on an AIP system. But I thought they wanted all in house work to focus on nuke subs so they were going for established designs like Scorpenes instead of designing onein house.

Actually Diesel subs. every country is ready to provide, If India itself design and develop it will cost even more and not upto that mark available in market, In case of nuclear no state can sell these one so India preferred to focus all it energy on Nuclear subs.

 

[Providence]

depends on the tonnage of the sub I think.

A 12000-13000 ton SSN needs a 180-190 MW reactor(Like Akula).

But there are contrary example as well.Seawolf needs 45 MW reactor while Virginia needs 30 MW one.French Rubis has a 48 MW reactor,I'm no nuclear scientist,but that means India is already capable enough to develop a SSN effectively,right?

Yes the S8G on Ohio class and S9G on virginia class have the following characteristics

LOL.... what rubbish

Arihant has a 85 MW Nuclear reactor but more importantly a 70 MW Steam Turbine which is what actually powers the Submarine.

Assuming that a Submerged Arihant is 8,000 Tons, this is enough to push the submarine in excess of 37 Knots.

Compare this to the Akula which has a Seam Turbine of 74 MW pushing its 12,770 Tons (submerged) in excess of 32 Knots.

Better Still Arihant has TITANIUM Alloy Hull ..... which means it can go down to incredible depths and has a crush depth far in excess of most other submarines.

Don't be stupid. 85MW is installed capacity. Generated power is in the form of propulsion + electric + auxilliary

Find the breakup first !

I am aware of the article and the history of how our SSN was converted into an SSBN.

That is why Arihant carries space for only 4 missiles.

However the news of Russian help in developing the Reactor is total fabrication and lies.

The Entire Arihant PW Reactor was designed and built totally in India by BARC.

V.K. Mehra gave leadership to the reactor development programme
H.S. Kamat was in charge of fuel development,
B.K. Bera, A.K. Suri and R.P. Singh played important roles on the fuel side.
The contribution of G.P. Srivastava, M. Mahapatra and R.K. Patil was formidable in control and instrumentation.
R.S. Yadav dealt with the design and manufacture of one of the most important components, the reactor pressure vessel.
C.G. Utge was responsible for the development of high-pressure, high-temperature equipment.

IT would be a gross disservice to the Nation aon to these scients if you were to credit the reactor to Russia.

Russian help was to provide us with Nuclear grade Uranium to fuel the Ractor.

What ? Russia's rubin design bureau assisted you guys. No harm in accepting it with humility !

 

[sankranti]

You are correct on the indigenously designed 85 MW reactor but 190MW is what I am saying seems very similar or perhaps helped by Russians more as technical advisories.

If I recall correctly initially there were 3 reactor designs for ATV which were rejected after some brief field tests in late 79s and 84-88s time frame owing to instability. It was of course announced in 1996 Delhi AIR about a successful N sub reactor somewhere in eastern India. But nobody ever talked about it.

The arihant present reactor rumoured to be 85MW seems to be mostly in-house. But I am sure its that rumoured reactor test which I am sure may be based on earlier Russian designs which may be now upgraded to incorporate our recent advancements in PWR tech and seek that as a heart for heavier subs.

Interestingly with 6 torpedo tubes, Arihant looks less like SSBN honestly more like SSGN with the heavy ballistic missile tubes too.

83.5 MW PWR on the Arihant is not a "Rumour", its a reported FACT.

You do understand the difference, don't you ? or do you wish to mix Facts and Rumours and spin conspiracy theory just to satisfy your desperate "desire' that Russia somehow "helped" us ?

The SSBN for now and the SSN will continue to have the same PWR which Arihant uses since it will provide excellent power to drive the submarines.


The 190 MW reactor is the rumour since it is not used in the Submarine and there are NO reports that it will be used or that it has even be provided or that it even Exist. .

You can't fabricate nuclear fuel and can fabricate a miniaturized reactor, *all by yourselves*.......... in just one go, that too by not going through the learning curve of designing a totally indigenous world-class diesel-electric submarine......... who are you kidding? Give the credit to Russian design bureau, where it's due, which in this case points to the whole damn submarine.

Most of your *break throughs* are like a transparent glass, from Agni to K series, the whole world can see through them, other than Indian awam, and that too, some highly educated Indian awam. Don't you guys stop at some point and think, why, how, wtf sometimes - or you're fed "indigenous" koolaid from your pre-school days?

[Gen Padmanabhan]

One go? R&D program was going on since 1990 or maybe you dont know anything about Indian PWR R&D program?

And in no case, this reactor is miniaturized, the reactor meant to go in SSN with HEU is miniaturized.

Building a submarine is not just R&D, and try to understand what is a miniaturized reactor.

And in no case, this reactor is miniaturized, the reactor meant to go in SSN with HEU meant to be miniaturized.

This is wrong, Russia helped in security & safety equipments, also all the pressure valves tested by the Russia.

I know what is miniaturized, and in no case a LEU reactor can be miniaturized.

Building a submarine is not just R&D, and try to understand what is a miniaturized reactor.

Further you was talking about reactor, not submarine. Changing the topic?

LOL...what do you mean "installed capacity", what other kind is there ?

The 70MW Steam Turbine provides 47,000 Hp to drive generators which supply the ship with electricity and drive the main propulsion turbines. 47 KHp is more than Sufficient for Both. Only an idiot will need the breakup to determine if it is.

What ? Russia's rubin design bureau assisted you guys. No harm in accepting it with humility !

False Humility is for Idiots and Fools who are ignorant of facts and for people with low self esteem. Maybe you have encountered too many Indians of that kind in PDF and seem to think that is the general trend.

Since I am neither of the two, I will rather laugh at you for making such foolish and unsubstantiated claims. Maybe you need to learn some Humility and learn to appreciate honest work.

This is wrong, Russia helped in security & safety equipments, also all the pressure valves tested by the Russia.

I will be happy to believe you. Kindly provide Links to your claim.

 

[Gen Padmanabhan]

I will be happy to believe you. Kindly provide Links to your claim.

Links?

Can you provide the links that Russia helped India in enriching LEU? Did they provided the Gas Centrifuge technology to India?
Will you provide the proofs of the FACT that in INS Arihant 85 MW reactor is installed? Will you able to provide proofs the power of reactor meant for propeller, and not as 15% rule? You even know how much power Sonar consume?

Ask those facts which you able to grasp, dont talk BS here & there.

This much khujli is not good you know. The scientists and the delays in developing these missiles andthe numbers of abs spread across the country and our huge economy, large MNCs are behind development of this missiles.

Your country is the only one who develops everything without a single failure just out of a complex with out any good company or R&D centre.

So dont open your mouth.

What is nuclear grade Uranium? Will you elaborate?

Uranium Yellow Cake not meant to be nuclear?

 

[Kinetic]

or buy 6 nuc subs from russia?

No they are designed and developed in India. India builds defence ships in 6 govt shipyards and 4 private shipyards. All of them are much larger than Karachi.

LOL.... Since YOU have made the claim, YOU are required to provide the Link you Moron. Not me

I am not required to provide ANY Link for ANY of YOUR foolish claims.

Work on second n­uclear sub reactor begins

"Arihant’s 85 MW light water reactor that runs on enriched Uranium fuel is ready. "

Ohh, this become your proof. Seriously?

Or what if I say this 85 MW is not MW but MW(Th). But still you unable to grasp this argument.
