Deciding to retire a coal-fired unit is often a tough call, but even tougher decisions follow. The next steps taken by a generation owner have multiple economic, environmental, and stakeholder consequences. Since 2000, U.S. generating companies (Gencos) have announced the closure of more than 200 coal-fired power plants, totaling 102 GW of generating capacity. Closures […]

An “ice wall” put up by Tokyo Electric Power Co. (TEPCO) around its four crippled reactor units at Fukushima Daiichi reportedly isn’t working as planned to keep out groundwater flowing into the devastated nuclear plant. According to The Asahi Shimbun, an expert panel at Japan’s Nuclear Regulation Authority on August 18 said that though five […]

The International Energy Agency predicts that nearly 200 reactors will be decommissioned during the next 25 years. Industry best practices and new technology can help make the process go more smoothly. It may not come as a surprise, but the average age of operating reactors in the U.S. is greater than 35 years. There hasn’t […]

When the decision is made to retire a power plant, the work of getting there is just beginning. Maintaining safe and reliable generation requires strong leadership, clear communications, and heightened attention to operations and maintenance, staff morale, and post-shutdown plans.   For utilities and other generators facing the challenge of winding down operations at an […]

The Report on Status of Decommissioning Funding for Shutdown Reactors—due annually—indicated that there was […]

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. […]

Operators at Entergy’s Vermont Yankee Nuclear Power Station (VY) took the plant offline permanently on Dec. 29 at 12:12 p.m. EST, ending a 42-year operational history. The shutdown is the first step in what is expected to be a decades-long decommissioning process for the plant. VY follows several other nuclear plants that have begun the […]

Decommissioning the Vermont Yankee nuclear plant will cost up to $1.24 billion, owner Entergy Corp. said in a study submitted to Vermont regulators on Friday.  Entergy Nuclear Vermont Yankee (ENVY) plans to shutter the reactor in late 2014. The decision to close the plant stems from a settlement agreement negotiated by several Vermont state agencies […]

The decommissioning of nuclear plants has developed into a mature industry in the U.S. It started in the 1960s with the dismantling of low-power prototype and test reactors originally built to demonstrate
