OKB Gidropress JSC have completed bench acceptance tests of CPS drives ShEM-3
In June 2021, the OKB Gidropress JSC have completed bench acceptance testing of a set of pitch electromagnetic drives of reactor control and protection system (CPS drives ShEM-3 ) for Rooppur NPP, Unit 2 (Republic of Bangladesh). The set consisted of 135 drives. The tests were carried out on test benches of experimental and research division of the company.
The tests were carried out in the thermohydrodynamic conditions, as close as possible to the real ones. During the tests, operability of each drive in the set, intended for delivery to Rooppur NPP was confirmed.
The CPS drive ShEM-3 is designed for reactor start-up, power control and shutdown by introducing CPS absorbing rods into or out of the core. The drive is designed and manufactured by OKB Gidropress JSC. The company is the developer of all modifications of ShEM-3 drives for NPPs with VVER-type reactors.
OKB Gidropress JSC was one of the first companies to implement the Rosatom Production System (RPS) into the company's business processes. The pioneer in this work was the mechanical shop. The result of the RPS measures was a significant breakthrough in the production volume of ShEM-3 drives.
