The Shaw Group has awarded an engineering, procurement and construction (EPC) contract for a new transmission switchyard and offsite power system for its planned new reactors at the VC Summer power station in South Carolina to Pike Electric Corporation.

Engineering for the 230 kV switchyard project will begin immediately,
with construction due to be completed by the end of 2015, according to
Pike chairman and CEO Eric Pike, who said his
company was extremely pleased to have been selected. "This EPC award is
important for Pike, as it recognizes our full platform of energy
solutions and fulfils a strategic goal to participate in the
opportunities presented by the renewed interest in US nuclear power,"
The award of the switchyard contract would appear to signal a real
intent to go ahead with the project to build the two planned AP1000
pressurized water reactors (PWRs) at the site, which is already home to
a 966 MWe PWR. South Carolina Electric and Gas (SCE&G), the main
subsidiary of Scana Corp, submitted a combined construction and
operating licence application for the two new units to the US Nuclear
Regulatory Commission in March 2008. Soon afterwards, it signed an EPC
contract with the Shaw-Westinghouse AP1000 consortium for the two 1117
MWe reactors. The units, known as Summer 2 and 3, are pencilled in for
start-up dates of 2016 and 2019 respectively.
The plant has also been shortlisted as a possible recipient of a
federal loan guarantee from the US Department of Energy (DoE). Loan
guarantees, which should make it easier for would-be reactor builders
to ensure they can raise the finance for new plants, are widely seen as
crucial to ensuring the construction of the first wave of new US
nuclear units goes ahead.
The Westinghouse AP1000 selected for the Summer units received design certification from the NRC in 2006, but Westinghouse has subsequently revised the design. The revisions are now undergoing review by the NRC. Two AP1000s are under construction in China, with two more contracted and others planned.
The NRC has to date received COL applications for 26 new nuclear reactors in the USA at 17 different sites. However a COL application does not signal any commitment to build a new plant, and some applicants have since asked NRC to suspend, or partially suspend, work on their applications for various reasons ranging from difficulties in financing to uncertainties over as-yet uncertified reactor designs. Nevertheless, early contracts have been placed for long lead-time components for many of the projects.
