DOE Considers Subsidies Modeled on Renewables for Small Modular Nuclear Reactors

State-imposed standards and financial incentives such as those used to spur widespread adoption of renewables technologies offer a promising model to address challenges to commercialize small modular reactors (SMRs), says a report by the U.S. Department of Energy’s (DOE’s) Office of Nuclear Energy. But to make a meaningful impact, nearly $10 billion in incentives will […]

New Digital Safety System Controller Approved for Nuclear Plants

The U.S. Nuclear Regulatory Commission has approved the use of Mitsubishi Electric Total Advanced Control (MELTAC) Nplus S digital safety system controllers in U.S. nuclear power plants. While new to the U.S. industry, Mitsubishi said the MELTAC system is already deployed in 38 nuclear power plants around the world, primarily in Japan and China. MELTAC […]

The Importance of RTO Maintenance

The importance of RTO maintenance
RTOs or Regenerative Thermal Oxidizers control emissions without producing harmful byproducts or hazardous waste. They help destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other odorous emissions created during normal manufacturing and industrial processes by combusting them into carbon dioxide and water. RTOs pass hot exhaust gas and cooler

Toshiba Scraps Massive AP1000 Nuclear Project in the UK

Taking another steep hit from its beleaguered nuclear business, Toshiba Corp. said it will withdraw from construction of the proposed 3.8-GW Moorside nuclear plant in the UK, a project expected to comprise three AP1000 reactors.   The Tokyo-based conglomerate said on November 8 that it had also taken steps to “wind up” NuGeneration Ltd. (NuGen), […]

TVA Extends Deadline for Bellefonte Nuclear Plant Deal

A Tennessee businessman now has until the end of November to finalize a two-year-old purchase agreement for the unfinished Bellefonte nuclear power plant in Alabama. The Tennessee Valley Authority (TVA), which began building the plant in 1974 but ended construction in 1988 amid a downturn in the nuclear power industry, on November 9 said it […]

THE BIG PICTURE: Small Modular Reactors

Interest in small modular reactors (SMRs) has ramped up of late owing to applications in niche electricity or energy markets where large reactors would not be viable—such as for cogeneration in countries with small grids, remote and off-grid areas, and for nuclear/renewable hybrid projects. Modular attributes may also enable SMRs to target the economics of […]

Takahama a Model for Japanese Nuclear Restarts

The challenges for Japan’s nuclear power industry have been many in the wake of the Fukushima disaster. Returning units to commercial operation requires meeting new government safety standards, along with

Implementing an ASME Covered Piping Systems Program

Power plant piping with a nominal pipe size of four inches or larger that carries steam or water operating at greater than 750F or 1,025 psi is considered a “covered piping system.” That means the
