Researchers at the US Department of Energy's Sandia National Laboratory have successfully tested a new power system based on a closed-loop Brayton cycle to deliver electricity to the grid. The system could dramatically increase the efficiency of power plants including current and new advanced reactor systems as well as gas-fired and concentrated solar plants.

GE Steam Power announced today that it has designed and manufactured the largest-ever (75-inch) last-stage blade for its Arabelle low-pressure rotor. The blade will enable the Hinkley Point C nuclear power plant under construction in Somerset, England to produce 3.2 GWe of CO2 free power, GE said. Once completed, this Arabelle steam turbine will be the most powerful nuclear steam turbine in operation. It was tested at GE's factory in Belfort, France.

The report, ‘Projected Costs of Generating Electricity’, says the LCOE of nuclear in 2025 will range from about $55-$95 per MWh. This compares to a maximum of almost $100/MWh for coal and about $80/MWh for gas. The cheapest non-dispatchable source of electricity is onshore wind of more than 1 MW, with an LCOE of $40-$50/MWh. Offshore wind is about $80-$110/MWh and utility scale solar PV $40-$80/MWh.
For nuclear plants that are in long-term operation, the cost falls considerably, with an LCOE of less than $40/MWh. Prolonging the operation of existing nuclear power plants is the most cost-effective source of low-carbon electricity. Hydroelectric power can provide a similar contribution at comparable costs, but remains highly dependent on the natural endowments of individual countries.
LCOE captures both capital and operating costs that need to be covered. It is essentially the long-term price at which the electricity produced by a power plant will have to be sold at for the investor to cover all their costs.

China's first 300MWe nuclear reactor cooling pump, developed by Harbin Electric Corporation is ready for mass production after being approved by the China Machinery Industry Federation. Previously, China had depended on imports for key components of pressurized water reactor nuclear power plants. The cooling pump was tested for 200 hours of continuous operation under automated high-temperature and high-pressure conditions. Harbin said the pump - which took six years to develop - completed flow assessment tests in April 2015 and hot function tests on 8 March.
