Bangladesh has become the newest entrant into the nuclear club with the construction of two atomic power plants. It will be the third South Asian country after India and Pakistan to access nuclear energy -- a development that could alter the power structure in South Asia. Hectic construction has started in Rooppur, 160 km from Bangladesh capital Dhaka, where two 1,200 MW power plants are being built with Russian help. The first of Rooppur's two units will be commissioned in 2023, the second a year after.
