Amentum has been selected as consultant for the dismantling of steam drum separators in Units 1 and 2 of Ignalina Nuclear Power Plant in Lithuania.
US-based engineering firm Amentum has been selected as consultant for the dismantling of steam drum separators in Units 1 and 2 of Ignalina Nuclear Power Plant (INPP) in Lithuania.
The seven-year contract is valued at €5.5 million and will be administered by the European Bank for Reconstruction and Development and funded by European Commission grants.
Amentum will help INPP manage the removal of the steam drum separators – large drums installed over the graphite core to divert steam to the turbines.
The project management unit will oversee the design and safety justification for dismantling and fragmentation of the drums and associated equipment, which are located in the plant’s radiologically contaminated primary circuit.

“The FIDIC service provider, Amentum, is a significant contributor to the dismantling of the steam drum separators. Their large international experience both as a FIDIC engineer and while working in various similar nuclear power projects will be a contributory factor to the success of the project’s joint implementation,” said Linas Baužys, director general of INPP.
Ignalina Nuclear Power Plant's two RBMK-1500 reactors generated up to 70% of Lithuania’s electricity before the plant was shut down in 2009.
The water-cooled graphite-moderated channel-type power reactors had a thermal power output of 4800MW per unit, however, after the Chernobyl accident the RBMK-1500 reactors were allowed to be operated with a thermal power output not exceeding 4200MW.
During the 26 years of operation Ignalina NPP has produced 307,1 billion kWh of electricity: Unit 1 – 136,9 billion kWh and Unit 2 – 170,2 billion kWh. The total amount of electricity sold is 279, 8 billion kWh.
Amentum’s heritage firms began working there more than 20 years ago, helping to deliver a New Interim Spent Fuel Storage Facility and other facilities required for decommissioning.
