The Shaw Group has renewed its contract with STP Nuclear Operating Company in the US to provide maintenance and modification services to operating units 1 and 2 of its nuclear power facility.

Shaw began providing maintenance and modification services to the South Texas Project in 2004, completing nine refuelling outages since 2005.

As part of its scope of work at the South Texas Project, in June this year Shaw assisted in the on-site decommissioning of reactor vessel heads. The original reactor vessel heads were cut and decommissioned on-site before secure shipping to a long-term storage facility. Shaw successfully cut, removed and packed more than 150 elements and securely enclosed the dome of the reactor head.

“This contract renewal demonstrates Shaw’s long-term commitment to reliably execute work for South Texas Project’s refueling outages, on-line operations, modifications and special projects,” said Clarence Ray, chief executive officer of Shaw’s Power Group.

The value of the five-year contract was not disclosed but will be included in its Plant Services segment’s backlog of unfilled orders in the fourth quarter of fiscal year 2011.

Shaw currently provides maintenance and modification services to 41 of the 104 nuclear power operating units in the US, including the country’s two largest fleets.
