GE Hitachi Nuclear Energy Awarded Contract to Support Decommissioning of Pilgrim Nuclear Power Station

December 03, 2019

WILMINGTON, North Carolina—December 3, 2019—GE Hitachi Nuclear Energy (GEH) announced today that it has been awarded a contract by Comprehensive Decommissioning International, LLC (CDI) to decommission the reactor internals and reactor pressure vessel at the Pilgrim Nuclear Power Station in Plymouth, Massachusetts.  

Employing cutting-edge technology, GEH will dismantle, segment and pack reactor internals and the reactor pressure vessel of the boiling water reactor that was shut down in May 2019. All handling and segmentation will be carried out underwater and will be accomplished using the Primary Segmentation System that was designed in conjunction with REI Nuclear. GEH acquired the business and certain assets of REI Nuclear in December 2018. 

"We are pleased to continue to support CDI with innovative technology, proven processes and an experienced team that is focused on safety and efficiency," said Jay Wileman, President & CEO, GEH.    

On August 26, 2019, Holtec International’s subsidiaries completed the acquisition of the Pilgrim Nuclear Power Station from Entergy Corporation. This followed the approval by the Nuclear Regulatory Commission (NRC) to transfer the plant’s operating license to Holtec subsidiaries Holtec Pilgrim, LLC as the owner, and Holtec Decommissioning International, LLC (HDI) as the license holder and decommissioning operator for the plant. Holtec will contract with CDI, a joint venture company of Holtec International and SNC-Lavalin, to perform the decommissioning, including demolition and site cleanup. 

GEH offers comprehensive decommissioning project expertise, including experience gained from reactor internals replacement projects in Japan and segmentation scope for extended power uprate projects in the U.S. GEH recently completed the segmentation of reactor internals at Oskarshamn Nuclear Power Plant (OKG) Unit 2 in Sweden and is now conducting the segmentation of OKG Unit 1.   

In July 2019 GEH was awarded a contract by CDI to decommission reactor internals and the reactor pressure vessel at the Oyster Creek Nuclear Generating Station in Lacey Township, New Jersey.
