What similrity? That the use of sodium for cooling. All the similarities that you talk about have been published information that have been available since the 1960\'s. In fact, the russian fast breeder uses exactly the same technology that the US fast breeder program used in the late 1950\'s and 1960\'s. The US shut it down as the uranium technology was a lot cheaper and because the FBR poses a lot of safety and environmental problem. So, using your logic we can say that India is using US technology as the Russian FBR technology still uses the 1950\'s US and French technologies.
India (IGARC) built the tiny 13MWe test reactor in Kalpakkam as a part/relult of its indigenous FBR development program. Based on the success of this program, IGARC is now building a 500MWe pilot reactor at Kalpakkam. If Russia gave all the technology, then what was the need to start with a mini test reactor and then taking the trouble to scaleup to the 500MWe reactor?
You have not given us any credible reference that points to Russia supplying the FBR technology to India. Neither have you given and supporting refeence to your first claim that Russia supplied enrichment plant for bomb grade.
