Exelon CEO Clarifies Headline-Grabbing No-Grid-Emergency Comment

Chris Crane, CEO of Exelon Corp., seemed to take umbrage with the way comments he made on June 5 were reported by Utility Dive. The website published the headline “Exelon CEO: No grid emergency to justify DOE coal, nuke bailout,” but Crane went out of his way to clarify his position while on stage participating […]

India’s Power Industry Struggles to Solve Pollution Problems

In a bid to tamp down pollution, India’s government in December 2015 notified the country’s coal generators they would need to meet—for the first time—new emissions limits for nitrogen oxides (NOx), sulfur dioxide (SO2), and mercury, as well as tightened limits for particulate matter (PM) and water consumption. The gazetted notification gave new plants until […]

Maintaining Nuclear Plant Ice Condensers: A ‘Cool’ Responsibility

Although nuclear plant ice condensers are rare—only seven sites throughout the world have them—the theory behind these passive heat sinks is quite novel. In fact, some next-generation plant designers have built upon the concept and incorporated passive accident intervention schemes into their plans. A nuclear plant ice condenser is a passive, static heat sink that […]

The Shift from Coal to Biomass Is on in Europe

Various schemes are underway in Europe as nations use existing coal-fired power plants to generate electricity without coal as the feedstock. With rising carbon prices, some big utilities are repowering with

December 2000—Milledgeville, Ga.: About 35,000 gallons of wastewater laden with coal ash is released from Georgia Power’s Plant Branch into Lake Sinclair when a mechanical failure of an isolation valve causes water from an ash pond to be siphoned back and discharged through the cooling water tunnel system into the lake. Plant Branch has since been retired to meet environmental rules, though the EPA continues to scrutinize three of its five coal ash ponds, which have received a significant or high hazard rating.

Why the EPA’s Proposed Coal Ash Rule Is Concerning

Over the past decade, together with my students and colleagues at Duke University and other academic institutions, I have conducted scientific research and published 13 scientific articles on different aspects

New Jersey Nuclear and Renewable Energy Bills Signed by Governor

New Jersey Gov. Phil Murphy signed a few important energy bills on May 23 including one (S-2313) that establishes a zero emissions certificate (ZEC) program, which reportedly will provide the state’s nuclear power plants with $300 million a year in ratepayer subsidies. To qualify, the plants must demonstrate that they make a significant contribution to […]
