Delays and other contested costs are expected to push the price for two new units being constructed at the V.C. Summer Nuclear Generating Station up by $980 million, a petition freshly filed by South Carolina Electric & Gas Co. (SCE&G) with the Public Service Commission of South Carolina (SCPSC) shows. SCE&G made the filing to […]

Four years after the massive earthquake and ensuing tsunami heavily damaged the Fukushima Daiichi nuclear plant in Japan, cleanup efforts continue amid new challenges, while Japan has made little progress on the policy front. The Ongoing Crisis at Daiichi By the fourth anniversary of the devastating events at Fukushima, the situation onsite has improved markedly, […]

The U.S. Energy Information Administration (EIA) released 2015 scheduled capacity additions and retirements on Mar. 10, and the news was not good for the coal industry. As has been the trend for several years, coal-fired generation accounts for the majority of expected retirements (12.9 GW of the nearly 16 GW total). However, most of the […]

The Tennessee Valley Authority (TVA) may further reduce its coal-fired capacity and scrap its unfinished Bellefonte nuclear power plant, the utility’s long-awaited draft power generation strategy unveiled on March 9 shows. 
 The federally owned corporation has been developing its 2015 Integrated Resource Plan (IRP), essentially a power planning roadmap to 2033, since fall 2013. The […]

French nuclear firm AREVA’s dismal financial results for 2014 are indicative of the continuing stagnation of nuclear operations, a lack of competitiveness, and the company’s difficulties in managing the risks inherent in large projects, CEO Philippe Knoche said today. The company reported a loss of €4.9 billion ($5.6 billion) for 2014 in line with a […]

A bipartisan group of Illinois legislators have introduced bills that propose a market-based solution to curb carbon emissions and ensure continued operation of the state’s nuclear power plants. The bills SB 1585 and HB 3293 introduced in the state Senate and House would enact the Illinois Low Carbon Portfolio Standard. That measure, like a renewable […]

Integrating more variable generation and storage, but no new nuclear units, are among the characteristics Exelon sees in the utility of the future, as outlined by Chief Strategy Officer William A. Von Hoene Jr. at the MIT Energy Conference, held Feb. 27–28. He began his Saturday address by saying that innovation is “absolutely indispensible.” Old, […]

Late last year, Japanese engineers and technicians accomplished a major milestone nearly four years after the most damaging light-water reactor accident in history at the Fukushima Daiichi nuclear station

The Nuclear Regulatory Commission (NRC) on Monday began a special inspection of damage to the containment vessel at Unit 2 of SCANA’s Summer nuclear plant, which is under construction in South Carolina.   The inadvertent damage stems from an incident during the week of Feb. 9, the NRC said. “Chicago Bridge & Iron (CB&I) workers […]

France will look at all options in an attempt to overhaul its state-run nuclear industry, French Energy Minister Ségolène Royal told reporters on Monday, after AREVA reported a $5.6 billion loss for 2014.  The nuclear giant announced in a Feb. 23 statement that it expects a hefty €4.9 billion loss ($5.6 billion) for 2014. The […]

It’s no surprise that the Palo Verde Nuclear Generating Station led the nation in electrical generation in 2014—it has done that for 23 consecutive years—but with a total output of 32.3 million MWh, it even bested its own previous record set in 2012. The Palo Verde plant is located about 45 miles west of Phoenix, […]

On the verge of being mothballed as a result of a challenging market for its power, the R. E. Ginna Nuclear Power Plant in western New York got a three-and-a-half-year reprieve when plant owner Exelon reached a reliability support service agreement (RSSA) with Rochester Gas & Electric (RG&E) on Feb. 13. The deal will keep […]

“The coolest thing on Earth” is, according to its new director, a young federal agency that has a unique focus on pushing technology frontiers and an “unblinking attention” to market realities. One thing you can say for sure about the energy world, said Dr. Ellen Williams (Figure 1), incoming director of ARPA-E (Advanced Research Projects […]

Southern Co. said in a regulatory filing on Jan. 30 that its two-unit expansion at the Vogtle nuclear power plant in Georgia may be delayed another 18 months, with its costs expected to rise at least $720 million. The company was informed of the delays by Westinghouse and CB&I, which are supplying and building the […]

Nuclear power station water storage tanks, located above ground or underground, are constructed of aluminum, stainless steel, or carbon steel. All have naturally occurring electro-chemical processes that can eventually deteriorate the metal, resulting in leaks. Defects that develop on the underside of tank floors are particularly difficult to detect and measure. The Nuclear Energy Institute […]

Despite its efficiency and environmental benefits, combined heat and power (CHP) generation has languished at around 10% of worldwide capacity for more than a decade. But a global review shows growth in some sectors and promising new technology on the way. The statistics are both eye-opening and somewhat depressing. Globally, according to the International Energy […]

A combination of spent fuel pools reaching capacity, security concerns, and mostly nonexistent policies regarding long-term consolidated storage of nuclear waste is making dry cask storage the only way forward for most nations with nuclear power reactors. Around the world, demand for dry cask storage facilities for spent nuclear fuel (SNF) is on the rise. […]

More than six and a half years after the Department of Energy (DOE) submitted its license application seeking authorization to build a geologic repository, Nuclear Regulatory Commission (NRC) staff published the final two volumes of the safety evaluation report (SER) on the Yucca Mountain site. Released on Jan. 29, Volume 2 covers repository safety before […]

A powerful blizzard packing hurricane-strength winds that hit the northeast U.S. yesterday and dropped as much as two feet of snow in some areas forced the Pilgrim Nuclear Power Station offline after the distribution lines taking its electricity failed. According to a spokesperson with Entergy, Pilgrim’s owner, the plant shut down safely around 4 a.m. […]

The U.S. and India announced on Jan. 25 that negotiators had reached an agreement resolving the impasse over India’s nuclear liability law that had prevented U.S. companies from supplying reactors to India out of fear of potentially unlimited liability in the case of an accident. Details of the agreement, which would create a government-sponsored insurance […]

Answering questions in a video produced by the Nuclear Regulatory Commission (NRC), new chairman Stephen G. Burns says safety and security are the top priorities for the agency, but that being agile and nimble when things change is also important. Burns said one of the biggest challenges confronting the agency is the level of resources […]

The nuclear renaissance has turned into a nuclear retirement party. As recently as 2012, the U.S. had 104 operating nuclear reactors. With the retirement of Entergy’s Vermont Yankee plant at the end of December, that number has now fallen under 100 for the first time since the 1970s.  Yet as rapid as that pullback has […]

Two giants in the power industry—Westinghouse Electric Co. and Bechtel Corp.—have formed an alliance to provide decontamination, decommissioning, and remediation services to U.S. commercial nuclear power plants. The alliance is expected to provide a full range of services, including pre-shutdown planning, characterization, decontamination, licensing, project development and management, dismantling, demolition, waste handling, and site closeout. […]

Exelon’s R.E. Ginna Power Station in western New York may be the next U.S. nuclear plant to shut down in the face of competitive pressures if the company cannot get approval to substantially increase the rates it charges for the plant’s electricity. Ginna had a power purchase agreement with Rochester Gas & Electric that expired […]
