Swedish-based renewable energy developer OX2 has taken another step toward construction of its Aurora offshore wind farm, a 5.5-GW project sited between the islands of Gotland and Oland in the Baltic Sea.
OX2 on June 27 announced it had submitted a permit application to build the wind farm under the auspices of Sweden’s Exclusive Economic Zone. Aurora, still in an early development stage, is part of OX2’s 11.7-GW project portfolio for Sweden. Aurora at present is considered the largest single offshore wind farm under development worldwide; Ørsted’s Hornsea project off the UK coast in the North Sea has 7.5 GW of total capacity, but that installation includes four separate wind farms.
“This is the next step to realize the Aurora wind farm,” said Hillevi Priscar, country manager for OX2 in Sweden. “Together with our other planned offshore wind farms it constitutes a significant part of the electricity production Sweden needs, to reach the climate targets and to secure the production and energy independence of Sweden.”…
Florida Power & Light (FPL), the largest utility in Florida, said September 7 it would shut down its Turkey Point and St. Lucie nuclear power plants in the hopes of limiting potential damage from Hurricane Irma. The facilities are the only operating nuclear plants in the state.
FPL did not give specific timing for the shutdown, but the Nuclear Regulatory Commission (NRC) said it expects Turkey Point, located south of Miami, will be taken offline the evening of September 8, with the St. Lucie facility on Hutchinson Island, north of West Palm Beach, likely being shut down early on September 9. The effects of Irma, which could be the most-destructive hurricane to ever strike Florida, are expected to be felt in south Florida on Saturday, with conditions worsening throughout the weekend.
The two plants are each about 20 feet above sea level. The plants are protected by concrete and steel barriers, and were further reinforced for protection after the 2011 Fukushima nuclear disaster in Japan, when floodwaters from a tsunami after an earthquake caused multiple meltdowns at the Fukushima Daiichi Nuclear Power Plant.…
China National Nuclear Corp. (CNNC) completed the dome lift at Fuqing Unit 5—the world’s first power plant being constructed utilizing the HPR 1000 (also known as the Hualong One) reactor design—15 days ahead of schedule on May 25.
The feat was no small accomplishment. The dome weighs about 340 metric tons and has a diameter of 46.8 meters (more than half the length of a U.S. football field). It was said to be the world’s largest and highest dome lift ever undertaken at a nuclear construction site (Figure 1). The dome—composed of 153 prefabricated components divided into five layers—ensures the integrity of the unit’s reactor building.

“That the dome was lifted 15 days in advance proves that CNNC can construct the HPR 1000 which is a national key project in the field of nuclear power,” Wang Shoujun, chairman of CNNC, said in a press release.…
