A second set of emergency core cooling system (ECCS) tanks for the reactor core of the Rooppur Nuclear Power Plant (NPP) have been shipped to Bangladesh.
ZIO-Podolsk JSC, owned by Atomenergomash JSC, Rosatom Mechanical Engineering Division, manufactured and shipped the set of main equipment for the Rooppur NPP, said a press release.
The ECCS tanks are included in the reactor plant – one tank for each reactor coolant loop. The ECCS is designed to automatically supply boric acid cooling solution to the reactor core in case of coolant loss and would be put in operation in case of primary circuit emergency depressurization.
The total weight of the products shipped is 156 tonnes and the equipment's service life is 50 years. The tanks were delivered by railway to the seaport of St. Petersburg, where they were loaded onto a barge and sent to Bangladesh by sea.
The design documents were developed by ZIO-Podolsk NPP Equipment Department employees, who also provided manufacturing supervision.
JSC Atomenergomash is a supplier of the equipment package for the reactor hall and a large part of the turbine hall equipment for Rooppur NPP with reactor plant VVER-1200. The companies of the division manufacture: reactors, steam generators, pumps, and heat-exchanging equipment.
Rooppur NPP has been designed and is being constructed according to a Russian design by the Rosatom SC Engineering Division. It is due to consist of two power units, of 1200 MW each, with generation 3+ VVER reactors.
