Without Enrichment plant, FBR cannot work, because it needs highly enriched Uranium or Uranium mixed with Plutonium ( has to be produced in an enrichment plant) or Uranium-Thorium mixed ( again have to be produced in enrichment plant) in the First cycle. In the second cycle FBR produces more than enough plutonium, which can be used as fuel and nuclear weapons. Thus, from the second and particularly from thirs cycle FBR is self-sifficient; that is the beauty of FBR as opposed to American style Uranium based plants which needs continuous uranium fuel. Russia gave India in 1993 ( and to China) exactly the same FBR it has used commercially( the first one in the world) in USSR along with Enrichment plants( otherwise it would not work). The design of the Kalapakkam FBR plant is exactly the same as the Russian BN-600 fast breeder reactor. Before that after 1974, USSR gave India the Heavy Water Plants as well, so that India became self sufficient.
