Decommissioning Dounreay

Located on the north coast of Scotland, Dounreay was the center of the U.K.’s fast breeder reactor research program from 1954 until 1994. Three reactors—two fast breeder reactors and one research reactor—a chemical reprocessing plant and various waste facilities were built there.

Fleet Standardization—A Maintenance Success Story

The nuclear industry has long understood the value of standardizing practices across a fleet of generating assets; however, effective implementation of this practice is difficult.

Duke Energy Replaces Its Personnel Contamination Monitors at Oconee Nuclear Station

The Mirion Technologies Health Physics Division said that Duke Energy has signed a contract to buy and install its Two-Step-Exit whole body monitors and HandFoot-Fibre hand and foot monitors for Oconee Nuclear Station.

An Historical Survey of Leak-Before-Break in Nuclear Plant Piping

Leak-before-break (LBB) is a term that has been used for decades in reference to a methodology that means that a leak will be discovered prior to a fracture occurring in service. LBB is most often used in main steam lines of nuclear power plant piping and it has also been applied to missile casings, gas and oil pipelines and pressure vessels.

Significant Nuclear Project Risks and Control Strategies to Achieve Success

New nuclear power plant owners and their engineering, procurement and construction (EPC) contractors face serious challenges during construction to keep the plants’ completions on time and within budget. History has demonstrated that even managements’ most ardent efforts to achieve project success can be overwhelmed. This article focuses on the critical interface between the utility-owner, the EPC contractor and their subcontractors.

Delay for US AP1000 Reactors

Westinghouse Electric Co. announced in February that it expects delays for two AP1000 nuclear reactors it is building in Florida for Progress Energy. Westinghouse, owned by Japan’s Toshiba Corp., said it expected 18 to 36 months delay in starting two AP1000 nuclear reactors for Progress Energy. The first of the two reactors was supposed to produce electricity by 2018.

Koreans Pounce on UAE Tender

The United Arab Emirates took a bold step into the nuclear club with a $20 billion tender award to the Korean Electric Power Co. (KEPCO) for four APR1400 nuclear reactors with a toal capacity of 5.6 GW.

Coming Out Green

For the first time in 30 years, several U.S. companies are sharpening their shovels to build nuclear power plants. The week of Jan. 25, 2010, marked the inaugural U.S. celebration of National Nuclear Science Week during which the Secretary of Energy, Dr. Steven Chu, named a Blue Ribbon Commission on America’s Nuclear Future.

US Breaks Nuclear Ice

On Feb. 16, President Barack Obama made the first Department of Energy (DOE) loan guarantee announcement for nuclear projects. Southern Nuclear Co. and its consumer-owned utility partners will receive $8.3 billion in federal loan guarantees to build two new nuclear reactors at the Plant Vogtle station in eastern Georgia near the South Carolina border.
