Did some research on my own. BD submitted its own evaluation report to IAEA mid 2012
http://www.iaea.org/NuclearPower/Dow...Evaluation.pdf
in that document the Model is termed as VVER 1000 which uses water as a cooling mechanism. The report also says environmental impact assessment report has not been prepared yet.
I googled the VVER 1000 model and found out that it was designed in 1975...

food for thought!
