Coal-fired power stations rely on storing coal in large bunkers or silos. Over time, changes in the type and quality of coal can lead to poor flow during discharge, creating production inefficiencies and significantly reducing storage capacity. Manual intervention is frequently used to promote flow; however, this is a hazardous process for operators and fails […]

Georgia Power has completed placement of the basemat structural concrete for the nuclear island at the Vogtle Unit 4 site, where it is the second of two units currently under construction. Georgia Power says that the basemat concrete placement was completed in just under 41 hours, an efficiency it says matches the best time achieved […]

Integrating large quantities of variable energy resources into the North American bulk power system will require fundamental electricity system planning and operational changes to ensure continued reliability, the North American Electric Reliability Corporation (NERC) says in a new report that it prepared in collaboration with the California Independent System Operator Corporation (ISO). The assessment, “Maintaining Bulk-Power […]

The Nuclear Regulatory Commission (NRC) on Monday directed agency staff to complete the long-delayed safety evaluation report (SER) for the Department of Energy’s (DOE’s) license application to build the Yucca Mountain permanent waste repository. Reflecting the Obama administration’s opposition to the repository, the DOE in 2010 withdrew from the NRC its June 2008–submitted application to […]

So long as the federal government has no viable alternative to Yucca Mountain as a repository for nuclear waste, nuclear power ratepayers should not be charged an annual fee to cover the cost of that disposal, the U.S. Court of Appeals for the D.C. Circuit ruled on Tuesday. Finding for petitioners that include the National Association […]

Anyone operating a coal-fired power plant has faced the challenge of keeping coal-handling equipment free of blockages and plugging. Not only do material flow problems interrupt smooth plant operations, but they also require dirty, sometimes dangerous, and often unscheduled maintenance work. As in many other industries, remote-controlled tools can help solve this problem. Bulk material […]

The Minnesota Public Utilities Commission (MPUC) will hire a nuclear engineering consultant to investigate cost overruns associated with Xcel Energy’s Monticello Nuclear Generating Plant Life Cycle Management/Extended Power Uprate Project. The project, at an estimated cost of $320 million, was authorized by the MPUC in 2009 and included necessary upgrades to increase the 600-MW plant […]

The Tennessee Valley Authority (TVA) will retire more than 3 GW at eight coal units in Alabama and Kentucky to address “challenging trends” that point to lower power demand, a slow economy, uncertainty in commodity pricing, and tougher air pollution rules. The U.S. corporate agency’s board of directors on Nov. 14 approved plans to retire all […]

U.S. Energy Secretary Ernest Moniz announced last week that the final shipment of low enriched uranium (LEU) derived from Russian nuclear weapons had departed from the port of St. Petersburg, Russia. “For two decades, one in ten light bulbs in America has been powered by nuclear material from Russian nuclear warheads. The 1993 United States-Russian […]

Tokyo Electric Power Co. (TEPCO) today began the delicate process of removing spent fuel from Unit 4 of the crippled Fukushima Daiichi nuclear plant. The six-unit site has two reactor groups, comprising Units 1–4 and Units 5 and 6. Unit 4 is the only reactor of its group that did not suffer a meltdown following […]
