South Korea on July 24 put online its 24th nuclear power plant. Shin Wolsong Unit 2 (Figure 3) will be the last to use the domestically developed OPR-1000 reactor design. Originally called the Korean Standard

The French Parliament on July 22 finally adopted a law that caps nuclear power generation capacity at its current 63.2 GW. The measure will force utility EDF to shutter nuclear reactors before it starts up its

In today’s digital world, an optimally run power plant relies on valuable and accurate data in order to ensure assets are running reliably and with minimal downtime. Streaming in from control systems, SCADA

A federal judge on Thursday halted implementation of the Clean Water Rule that is controversial for its broad definition of “Waters of the U.S.” one day before it was to go into effect, saying it was likely that the Environmental Protection Agency (EPA) overstepped its authority when it promulgated the “exceptionally expansive” rule.  Judge Ralph […]

Entergy’s Pilgrim Nuclear Power Station outside Boston just can’t seem to shake its problems with unplanned shutdowns. The most recent one occurred on Aug. 22, when a broken air-nitrogen line caused a main steam isolation valve to close, trigging a reactor scram. This was the plant’s third unplanned shutdown in 2015. Pilgrim was forced offline […]

Kyushu Electric Power Co.’s restart of Sendai 1—the first Japanese reactor to begin operation under new safety standards after the Fukushima disaster—hit a technical hiccup last week, prompting the company to halt ramp up of power output. The utility said on Aug. 21 that it had suspended increasing output at the unit after an alarm […]

Exelon’s embattled nuclear fleet got more bad—though far from unexpected—news on Aug. 21 as the Oyster Creek, Quad Cities, and Three Mile Island nuclear power plants failed to clear in the 2018–19 PJM capacity auction. This means that the three plants will not receive capacity payments during that delivery year. This was despite a big […]

With all 40 remaining construction milestones for V.C. Summer Nuclear Station Units 2 and 3 behind schedule (33 by more than 18 months) as of June 30, South Carolina Electric & Gas Co. (SCE&G) awaits approval of the petition it filed with the Public Service Commission of South Carolina (SCPSC) to update its construction and […]

The power generation industry is undergoing a period of rapid transformation. A growing number of operators are considering the adoption of condition-based maintenance (CBM).  This whitepaper discusses the forces that are driving demand for CBM, how CBM works and why it is an effective alternative to planned maintenance strategies.

Nearly two years after Japan’s last nuclear power plant was shut down for safety checks, Kyushu Electric Power Co. has started up the 890-MW Sendai-1. The event marks a significant milestone for the country’s nuclear sector, which was crippled by the Fukushima disaster in 2011.  Kyushu started up Sendai-1 at 10:30 a.m. local time and […]

Though most power generators and states might have preferred to not deal at all with a new rule regulating greenhouse gas emissions, the final Clean Power Plan (CPP), released August 3, gives most of the power industry most of what it asked for in terms of revisions to the 2014 proposed plan. In any regulatory […]

According to data compiled and reported by Fraunhofer-Institut für Solare Energiesysteme ISE—a German-based solar energy research institute—from July 1 through August 5, solar and wind energy produced 6.24 TWh and 7.09 TWh of electricity respectively, compared to 5.94 TWh of nuclear power generation in Germany. Although it’s not the first time wind production has exceeded […]

Ameren Missouri has dropped plans to build a second nuclear unit at its Callaway Energy Center, citing shaky economics in the context of cheaper renewables, low demand, and other factors for its decision. “While we continue to believe nuclear power must be an important clean energy source for our company and country, as evidenced by […]

Furthering efforts to encourage clean energy innovation, the Energy Department released a funding opportunity announcement (FOA) to support the research, development, and demonstration of advanced reactor concepts. The announcement represents an early step in increasing investment in nuclear advanced reactor technologies, which have the potential to provide substantially enhanced operational performance, safety, security, economics, and […]

Reaction from utilities, environmental groups, and governmental leaders following the August 3 release of the Environmental Protection Agency’s (EPA’s) final Clean Power Plan rule was mixed. Some, such as Duke Energy CEO Lynn Good, pointed to the progress that has already been made in recent years to reduce carbon dioxide (CO2) emissions, noting that the […]

Editor’s note (Aug. 3): Adds compliance cost details, key changes The Environmental Protection Agency’s (EPA’s) final Clean Power Plan will seek to tamp down the nation’s carbon dioxide (CO2) emissions from the power sector by 32% from 2005 levels by 2030—about 9% more ambitious than its original proposal. The first-ever final national standards to limit […]

E.ON in late June announced that it wants to shutter its Oskarshamn 2 reactor (Figure 1) in southeastern Sweden because it is unprofitable. The announcement is the latest in a string of early nuclear plant retirements from around the world. 1. Early retirement. The 638-MW Oskarshamn 2 nuclear reactor, built in 1974, is at risk […]

Exelon’s Quad Cities nuclear plant in Illinois will not be economically viable despite changes in the PJM capacity market, and the company has to make a decision on closing it before the Illinois legislature can act on possible measures to save it, CEO Chris Crane said in Exelon’s second-quarter earnings call on July 29. Along […]

France’s state-owned utility EDF will snap up between 51% and 75% of troubled nuclear giant AREVA’s reactor business in a possible $2.96 billion deal.  While the French government owns about 87% of AREVA and 85% of EDF, the utility that operates the nation’s aging 58-reactor fleet, it has pledged to look at all options to […]

Nuclear Regulatory Commission (NRC) inspectors reported that the Tennessee Valley Authority’s performance during a recent assessment conducted at Watts Bar Unit 2 indicated that the plant is ready to startup and conduct power operations.

In a report released this week, M.J. Bradley & Associates found that in 2013 power plant SO2 emissions were 80% lower and NOx emissions were down 74% compared to releases in 1990—the year Congress passed major amendments to the Clean Air Act. The report, Benchmarking Air Emissions of the 100 Largest Electric Power Producers in […]

The nation’s 99 nuclear plants produce about 19% of the country’s power, but they also contribute about $60 billion annually to gross domestic product (GDP), a new Brattle Group report finds.  The report, “The Nuclear Industry’s Contribution to the U.S. Economy,” prepared for pro-nuclear group Nuclear Matters says, “Several factors are at play that may […]

A new report from the Government Accountability Office (GAO) reveals surprising aspects about how federal subsidies for electricity have been distributed, how the power generation mix has shifted, and how consumption has transformed since 2001.  The June 29–released report, “Generation Mix has Shifted, and Growth in Consumption has Slowed, Affecting System Operations and Prices,” responds […]

The Nuclear Regulatory Commission (NRC) released details from its security inspection program for commercial nuclear power reactors and Category I fuel cycle facilities, finding only one “failure to protect designated target set components effectively” during the 23 NRC-evaluated force-on-force (FOF) exercises conducted in 2014. Although not perfect, the marks are far better than inspection results […]
