GEH said it had completed the segmentation of reactor internals at Oskarshamn-1.
The company’s work at the Oskarshamn site began in 2017 with the dismantling and segmentation of reactor internals of Oskarshamn-2.
Jay Wileman, GEH president and chief executive, said the project was completed on schedule and budget.
In October 2015, OKG’s shareholders voted to close both Oskarshamn-1 and -2 over concerns about their economic viability.
Unit 1 was permanently shut down in June 2017 and Unit 2 in December 2016.
The Oskarshamn site has one unit in commercial operation, the 1,400-MW Oskarshamn-3.
