DOE Announces New Path to Test Advanced Nuclear Reactors

LCG, June 18, 2025--The U.S. Department of Energy (DOE) announced late today a new pilot program to expedite the testing of advanced nuclear reactor designs under DOE authority outside of the national laboratories. The new pilot program is intended to unlock private funding and provide a fast track to commercial licensing.

Offshore Wind Project in North Sea Advances

LCG, August 3, 2011--Italian cable manufacturer Prysmian and Siemens Energy are developing HelWin 2 to connect the North Sea offshore Amrumbank West Wind Project to the onshore grid for the customer, TenneT TSO GmbH of Bayreuth, Germany, with a high-voltage direct-current (HVDC) transmission line. The line is rated at 690 MW and is scheduled to be operational by 2015. Amrumbank West will be built in the North Sea, about 55 miles from the German mainland and approximately 22 miles west of the North Frisian island of Amrum.

The transmission interconnection includes an offshore converter platform HelWin beta, on which the Siemens HVDC Plus system for HVDC transmission will be installed, plus two power transformers and the gas-insulated high-voltage switchgear. Siemens will supply the fully equipped floating and self-erecting platform.

The 3-phase, alternating current (AC) generated by the wind turbines will be bundled on the offshore transformer platform and transmitted to the converter platform via a high-voltage cable, where the 155-kV AC will be stepped up and converted into the Siemens HVDC system. Power will then be transmitted via a 320-kV HVDC cable from on the platform under the sea to the grid connection point in B?ttel, northwest of the city of Hamburg, over 80 miles away, where a transformer and converter substation will convert the power back into AC for transmission and distribution.

Offshore wind development is growing in Europe. The European Wind Energy Association (EWEA) in January released information that a total of 883 MW of new capacity was installed last year at nine wind farms in five countries, thereby increasing the European offshore total to 2,964 MW. In the first six months of 2011, 101 offshore wind turbines, with a combined capacity of 348.1 MW, were fully grid connected. The United Kingdom leads Europe, with a total installed offshore wind capacity of 1,341 MW, or nearly half of the offshore capacity.
