The nuclear power industry is riding the green wave back into public favor, but it's still bound by a global energy landscape dominated by solar, wind and carbon sequestration. Veteran reporter Matthew Wald examines the trade-offs associated with alternative energy sources in his special feature.
A new study analyzing US nuclear reactors finds a range of electricity costs from 3 cents to 14 cents per kilowatt hour, with higher costs attributed to poor plant operation and security concerns. The study suggests that new technologies and safer reactors may not mitigate the financial risks associated with nuclear power.
The US Nuclear Regulatory Commission has awarded its first-ever early site permit for a new nuclear power reactor, marking a significant step in the country's nuclear renaissance. PNNL researchers are assisting NRC with environmental and safety reviews, and document preparation.
A new study suggests that increasing nuclear power production by a factor of three to ten could significantly reduce greenhouse gas emissions, but comes with significant drawbacks including massive nuclear waste generation and proliferation risks. The study's author emphasizes the need for a complete picture when choosing energy sources.
Researchers argue that emotions, rather than reason, drive public distrust in institutions. The study reveals that concerns about risk are directly linked to lack of knowledge and emotional dread. Building trust requires transparency and reporting back after public consultations.
A recent poll suggests that over half of the British public would accept new nuclear power stations to combat climate change, but most prefer renewable energy sources and energy efficiency. The survey highlights a need for balance in energy policy, with 63% supporting a mix of nuclear and renewables.
Researchers propose Assured Nuclear Fuel Services Initiative (ANSFI) to provide nuclear fuel services to countries without enrichment capabilities. The initiative aims to prevent proliferation by making it economically attractive for countries to join, reducing the risk of weapons development.
The Arctic and oceans hold mega-tons of methane hydrate, a cleanest and most abundant energy source. However, extracting and transporting it is challenging due to its gas form and expansion issues, as well as geo-political considerations and potential environmental impacts.
Emerging Generation IV machines will provide significant improvements in reactor design, economics, safety, and waste minimization. Advanced designs include high-temperature reactors that can produce hot water for communities or desalination energy.
A study led by University of Wisconsin-Madison professor Vicki Bier found no evidence that deregulation causes widespread safety lapses in the US nuclear power industry. However, it warned that the speed of change after deregulation could create potential safety hazards, and highlighted concerns over organizational changes, rapid downs...
A case study by INFORMS finds that organizations operating near safety borders rely on after-the-fact interventions rather than preparation. The study compares two nuclear facilities, highlighting the importance of anticipation, foresight, and countermeasures in staying within a zone of safety.
Renewable energy sources, such as solar and nuclear power, are crucial to fill the gap between energy demand and supply. John D. Edwards predicts that world crude oil production will peak in 2020 at 90 million barrels per day, emphasizing the importance of transitioning to cleaner energy options.
