Nuclear Construction Update: New Progress Made in Russia, UAE, and U.S.

August 9, 2018

Several milestones have been reached at nuclear power plant construction sites around the world including on the Leningrad II-2, Novovoronezh II-2, Barakah, and Plant Vogtle projects.

Russian Progress

At the Leningrad site, Rosatom—the Russian state atomic energy corporation—reported on August 7 that the main turbine equipment installation for Phase II Unit 2 was completed. The company said that the stator, separators, superheaters, deaerator, turbine condensers, high- and low-pressure heaters, and heat exchangers have all been installed. Work will now begin on insulation, low-current and electrical installation, and the laying of external and internal engineering networks.

Leningrad Phase I has four RBMK-1000 units, which were connected to the power grid between 1973 and 1981. Phase II will have four VVER-1200 units, two of which are currently under construction. Unit 1 was connected to the grid on March 9 and is currently in the final stages of commissioning. It was the second VVER-1200 unit to be grid connected. Novovoronezh 6 (also known as Novovoronezh Nuclear Power Plant [NPP] 2 Unit 1) was the first VVER-1200 to enter service.…

More U.S. Coal Units Closing Despite Possible Market Pricing Change

U.S. utilities continue to announce closures of financially troubled and older coal-fired power plants even as government officials work on a bailout plan to keep them operating.

Owners of a coal plant in Montana that has only been online since 2006 informed the state’s Public Service Commission (PSC) last week of plans to shutter the facility early next year if they can’t find a buyer. The news comes at the same time Louisville Gas & Electric and Kentucky Utilities (LG&E-KU) said it would close two long-running coal-fired units at the E.W. Brown Generating Station near Harrodsburg, Kentucky, in February 2019.

The announcements are the latest in a series of closures announced in recent months, including three large coal-fired plants in Texas—two operated by Vistra Energy and another by Luminant, a Vistra subsidiary—that generate about 4.2 GW of electricity, or about 12% of the state’s coal-fired generation capacity. Another large Texas plant, CPS Energy’s 840-MW Deely station in San Antonio, is scheduled to close in 2018.…

ITC: Imported PV Cells Hurting U.S. Solar Industry

In a unanimous decision, the U.S. International Trade Commission (ITC) on September 22 found that photovoltaic (PV) solar cells being imported into the U.S. are causing “serious injury, or threat of serious injury, to the domestic industry.”

The decision comes in a highly contested case filed by bankrupt solar panel manufacturer, Suniva, and SolarWorld. The two petitioners argue that imports of foreign-made solar panels and modules have made it impossible for them to compete in the domestic market. To alleviate this burden, the companies have proposed that tariffs be placed on all imported modules.

“On behalf of the entire solar cell and panel manufacturing industry, we welcome this important step toward securing relief from a surge of imports that has idled and shuttered dozens of factories, leaving thousands of workers without jobs,” Juergen Stein, CEO and president of SolarWorld Americas, said in a release following the announcement of the decision.

Two Against All

The rest of the solar cell and panel manufacturing industry, however, does not seem to want SolarWorld speaking on their behalf.…

Wind and Solar Cross 10% U.S. Generation Share as Prices for Solar Keep Falling

Marking a significant milestone, power generation from the combined utility-scale and small-scale wind and solar installations in the U.S. surpassed 10% of the nation’s total power generation in March, according to the Energy Information Administration (EIA).

The news comes on the heels of an announcement last week by the Solar Energy Industries Association (SEIA) that installed system prices for solar systems have fallen across all market segments. Also for the first time, fixed-tilt utility-scale systems dipped under the $ 1/W barrier, SEIA said.

Breaking the Barrier—on a Gigawatt-Watt Level

The EIA said on June 14 that generation from wind and solar has grown steadily since 2007. On an annual basis, wind and solar generation made up 7% of total U.S. power generation in 2016.

The EIA noted that wind and solar follow seasonal patterns. Wind patterns vary based on geography. Wind generators in Texas and Oklahoma, for example, have their highest output in spring, while California generators see a boost in output in the summer.…

Analysis Shows U.S. Nuclear Plants Losing $2.9 Billion Annually

Increased use of less-expensive natural gas and renewable sources of energy for power generation is putting financial pressure on U.S. nuclear power plants, according to an analysis of electricity costs from Bloomberg New Energy Finance (BNEF).

Nicholas Steckler, an analyst for BNEF, in a June 14 report said nuclear operators are losing about $ 2.9 billion a year. Steckler said nuclear plants are being paid $ 20/MWh to $ 30/MWh for their electricity, while their generation costs an average of $ 35/MWh.

The report says 34 of 61 U.S. nuclear plants are in the red. Steckler specifically cited merchant nuclear plants owned by FirstEnergy Corp., Entergy Corp., and Exelon.

In a statement, Entergy said it would not comment on individual plants but said “financial challenges due to sustained wholesale power price declines and unfavorable market conditions” are affecting the profitability of its nuclear operations. The company said it is now concentrating on its regulated utility business. Entergy, along with its wholesale commodities division, owns seven U.S.…

Chinese Reactor Is Ahead of Schedule as U.S. Nuclear Projects Flounder

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.…
