I am going to quote from an article on google knowledge with my comments and highlights on Indian indigenous nuclear submarine.
First the part which shows that the Russians help was acquired as Consultants by the Indians not only in Submarine design but also in reactor.
Asked if the Russians helped in miniaturizing the reactor, Banerjee said:
"No, no. They were consultants...Consultancy was done for the whole submarine, not for the power plant alone."
Ok, so it is, the whole submarine was produced with the help of the Russians, not really the work of the Indians. But as we know, Indians are very very keen on calling everything they copy as indigenous. Well you have to give it to them if they dont how are they going to justify the huge expense and delivery of every project late and over budget?
A miniaturized PWR reactor, like the one on the Arihant, became critical inside a simulated submarine pressure hull at Kalpakkum on 11 November 2003. It was declared operational on 22 September 2006 has been running successfully since then.
The test reactor is fitted on a 42-meter-long land-based prototype submarine with eight compartments housing complex electrical and control systems and simulating ocean conditions.
We have used the Russians as consultants. As far as efforts in designing, developing and maintaining the reactor are concerned, they are entirely ours, the BARC Director said.
S. Basu, Director, BARC Facilities at Kalpakkam, also asserted that everything is totally indigenous about the PWR developed at Kalpakkam. It has been developed by us. It is 100 per cent our reactor, he said.
So, as I thought the word indigenous was the name of the game 100% ours, indigenous.
Based on Russian Charlie II subs
India is reported to have acquired design of the Charlie II class nuclear submarines from Russia and the ATV was based on those designs. Along the way, in January 1988, India leased a Charlie class nuclear powered submarines from Russia to help the Navy familiarize itself with operating a nuclear submarine. The leased submarine was christened Chakra in the Indian Navy which operated it for three years. After the term of the lease ran out, the sub was returned to Russia.
The Arihant is 112m long as compared to 103m Charlie class subs, probably because of a section was added in the middle to accommodate its four missile tubes.
Its 10m beam is the same size as a Charlie class sub.
The evidence suggests as ever, it was a copy, but Indians denial is obvious from the no, no offered by Banerjee. Now comes the interesting part.
Like the Charlie II subs, Arihant has a single nuclear power plant which gives it a rather limited underwater speed of 24 kts. Not enough to chase warships or get away from them when it is detected.
It can not chase it targets and if it is detected by the enemy it can not escape. This is a sitting duck, if there ever was one. What is the actual use of this submarine then, if it can not chase the ships or escape?

.
Indian got the training for 3 years on the actual working model so they could operate the Indigenous copy of Charlie II with added length.
But at least Manmohan was gracious in accepting Russias role. Manmohan why not go all the way and accept it is Charlie II with modification for the missiles?
During the launch of INS Arihant on Sunday, July 26, Prime Minister Manmohan Singh did not mince words while acknowledging Russia's role in the fruition of the challenging project.
"I would also like to express our appreciation to our Russian friends for their consistent and invaluable cooperation, which symbolizes the close strategic partnership that we enjoy with Russia," he said.
In the Analysis it is declared as enhanced copy of Charlie II by google knowledge.
Though the Arihant is based on the Charlie II class, it likely incorporates a lot of advancements in propulsion, noise suppression, command and control, communication and sonar that the Russians learnt since they built the Charlie II subs, as well as what the Indians learnt while building German HDW 209 1500 submarines INS Shalki and INS Shankul - in the late eighties to early nineties.
Google knowledge article, also dispel the rumours it is Akula class submarine, like another of my Pakistani friend listed in this thread.
Unofficial illustrations of the boat show elements of Akula design like the towed sonar at the aft. However, Arihant is unlikely to be based on the Akula II or the more modern Graney class Russian subs, as reported in some sections of the press, since these subs use a twin hull design and are therefore considerably heavier. Not surprisingly the Akula is powered by a 190 MW reactor.
Well, despite whatever the evidence may suggest, it is officially an indigenous product of India like so many others. Who we to argue?
