DHAKA, May 23, 2020 (BSS) – Manufacture of Reactor Pressure Vessel (RPV)
for Unit-1 of Rooppur Nuclear Power Plant (RNPP) has recorded a further
development as the production of Core Barrel has been completed.
The Core Barrel was manufactured at the Volgodonsk Branch of AEM-
technology in Russia, according to a message received here today.
