They should have agreed to the current alignment. The land is not even developed. L&T allowed JVLR flyover to pass thru its Powai campus for a few hundred meters.

Re: INS Arihant (ATV) News and Discussion -2

Usually in a reactor the steam after driving turbines is condensed into water and reused. Sea water being colder is used in the heat exchanger to take away the heat and condense the water. I dont think sea water is desalinated for use in a reactor circuit.

With last of scorpenes to roll out by 2021, its good move to keep MDL line running. If the approval comes now we might see hopefully the new P 75i roll out by 2022 . Keep everything else same only addition we may see is the Drdo AIP plug, which the navy wanted in 5th and 6th scorpene.
