South Leads Biomass Power GrowthThe Carolinas were in the thick of it as southern states led the way to a 14% surge in U.S. electricity generation from biomass over the past five years – from 56 gigawatthours (GWh) in 2010 to 64 GWh.       In 2015, electricity generation from biomass across all sectors accounted for 11.3% of renewable electricity generation and 1.6% of total electricity generation in the United States.       Nearly half of the electricity generated from biomass in 2015 was at industrial facilities outside of the electric power sector, such as pulp and paper mills. Along the Cape Fear River, forest waste powers the International Paper plant in Riegelwood.       Within the electric power sector, biomass accounted for 6.3% of renewable electricity and 0.8% of total U.S. electricity generation. Four hundred daily truckloads of wood waste provide half of the energy at Southport Power which provides heat to ADM and electricity to Duke Energy.

GE Carolina High-Tech Gets US Test FundsThe U.S. Department of Energy is funding a GE Hitachi Nuclear Energy effort to lower the cost – in time and dollars -- of nuclear power plant replacement parts with 3D printing.       The $2 million additive manufacturing research project will use 3D printing to produce replacement part prototypes and subject the samples to a number of tests after irradiation in the Idaho National Laboratory’s Advanced Test Reactor.       The GE Hitachi project is part of an $80 million investment in 93 advanced nuclear technology projects the Energy Department announced in mid-June.       Funding from DOE’s Nuclear Science User Facilities program will give GE Hitachi access to state-of-the-art neutron and gamma irradiation and post-irradiation examination services, the Wilmington-based U.S.-Japanese nuclear venture explained.       As part of the research project, GE Hitachi said, it will produce sample nuclear power plant replacement parts which will be 3D printe…
Fukushima-enhanced flood concerns addressed The Nuclear Regulatory Commission has signed off on the flood protection improvements Duke Energy completed at its oldest nuclear power plant.
Concerns about flooding at the utility’s three-unit Oconee Nuclear Plant -- including the potential failure of the Jocassee Dam, located about 12 miles upstream from the plant – were addressed in a 2008 NRC staff letter.
After a tidal wave damaged the Fukushima Dai-ichi plant in 2011, the agency requested additional information on flooding as it worked to ensure that lessons learned from the situation in Japan were applied to U.S. plants including Oconee.
Duke submitted its flood hazard reevaluation report in 2013 and a revised report in 2015. The NRC accepted the modifications in that 2015 report as adequately protecting the Seneca, SC nuclear plant from a potential failure of the Jocassee Dam.
In April, Duke informed the NRC that the flooding modifications – including enhanced flood walls as well as mo…
GE slated for beyond 60Plans to extend two GE boiling water reactors (BWR) operating licenses beyond 60 years. Construction of a Westinghouse AP1000 reactor in Georgia passed a milestone. Such was the juxtaposition of old and new in last week’s nuclear news. Exelon said it plans to file with the Nuclear Regulatory Commission (NRC) seeking an additional 20-year operating license for Peach Bottom Atomic Power Station, co-owned Public Service Enterprise Group. Georgia Power said the last of four 375,000-pound reactor coolant pumps for Vogtle Unit 3 near Waynesboro, Georgia arrived via truck from Curtiss-Wright Corporation in Cheswick, Pennsylvania. Work on the pressurized water reactor is the most advanced of four under construction in the U.S. southeast. Last month Westinghouse said the world’s first AP1000 moved a step closer to commissioning with the completion of the cold hydrostatic test at Sanmen Unit 1 in Zhejiang Province, China.Completion of the test is a key step for the first of f…
