When a nuclear power plant experiences ground motion due to an earthquake, an evaluation may be needed before allowing the plant to continue operating or to resume operating if it has been shut down, as was the case after the seismic event that shut down both units at Dominion’s North Anna Power Station on August 23, 2011.

Hitachi announced on Tuesday that it had acquired Horizon Nuclear Power in a deal expected to be completed by the end of November. In another example of the global nature of the nuclear business, the Japanese firm purchased Horizon, which was developed by the UK to build new nuclear plants, from German companies RWE and E.ON.

The first quarterly update from the Tennessee Valley Authority (TVA) reporting construction progress of the Watts Bar Unit 2 nuclear reactor suggests that the project is on track for completion between September and December of 2015 and is within its budgeted cost range of $4 billion to $4.5 billion.

All turbo machinery is subject to degradation that, over time, will affect the system’s efficiency and operational performance. Precise monitoring of turbo machinery performance with continuous torque-monitoring systems can be used to identify gradual efficiency loss. That, in turn, allows a more focused maintenance scope to be developed that can return the system to its optimum operation and efficiency.

China regards nuclear energy as a critical part of its strategic goal of achieving sustainable economic development while reducing environmental pollution. An analysis by North China Electric Power University predicts that the pace of nuclear power development may slow for a short time as a result of the Fukushima accident, but nuclear power is still a top development priority.

A number of factors promote effective and responsible completion of EHS audit action plans, with the most important being the proper alignment of responsibility and authority for developing and implementing the audit action plan.

The Clean Water Act Section 316(b) rule changes regarding cooling water intake structures that are expected next year could affect up to 428 power plants, representing 1,156 individual units, according to the Electric Power Research Institute. Depending on plant size and the complexity of the retrofit project, retrofit capital costs could range from very low to over $500 million for large nuclear plants. The power industry total cost is projected to be over $100 billion.

On June 15, in response to a court order, the U.S. Environmental Protection Agency (EPA) proposed new lower limits on particulate matter (PM) emissions that are scheduled for release in mid-December, although that deadline may be missed. Even with implementation delays, now is a good time to start paying closer attention to the requirements of the proposed standard.

The fundamental design principles and process for modern steam desuperheating, or the attemperation of superheated steam in the power generation industry, have been evolving since the early 1930s. Meeting the requirement for steam quantity, quality, and temperature consistency is the foundation of traditional attemperator component design, particularly for fast-response combined cycle plants.

The Climax LM5200 and LM6200 portable milling machines are designed with a split rail system to easily perform both linear and gantry milling with a minimum of changeovers. A rigid, modular bed design allows shorter bed sections to be combined to fit the length of the work area, without losing rigidity, and to extend the […]

By Kennedy Maize (@kennedymaize) Washington, D.C., 24 October 2012 – Here’s one for climate science and policy wonks. Remember the Waxman-Markey cap-and-trade bill? Among the community of the climate alarmed, there was much gnashing of teeth, tearing of hair, and sack cloth and ashes when the legislation that passed the Democratic House in 2009 died […]

A 750-MW coal gasification plant with carbon sequestration proposed to be built in in Linden, N.J., is no longer under development, owner SCS Energy says on its website. The company said it has moved the commercial structure and process design for the PurGen project to the Hydrogen Energy California project, a fossil fuel gasification plant with carbon storage proposed for Kern County, Calif.

Duke Energy last week said that testing was under way in preparation for commercial operation next year of its 630-MW integrated gasification combined cycle (IGCC) Edwardsport power plant in Knox County, Ind.

A task force appointed by New York Gov. Andrew Cuomo (D) on Monday released a plan that calls for 3,200 MW of new power generation and transmission capacity funded with up to $5.7 billion in private investments.

The Federal Energy Regulatory Commission (FERC) last week proposed to require new standards addressing the impacts of a geomagnetic disturbance (GMD), saying that, though it recognized the strong disturbances that result in distortions to Earth’s magnetic field are infrequent, current mandatory reliability standards do not adequately address vulnerabilities.

The Department of the Interior (DOI) on Tuesday awarded NRG’s Delaware-based unit Bluewater Wind a lease for commercial development of a 450-MW offshore wind farm on 96,430 acres of federal waters about 11 nautical miles off the coast of Delaware. But NRG last year put that project on hold and has considered selling it.

The Kewaunee Power Station—a 556-MW nuclear facility in Carlton, Wis.—will be shut down and decommissioned starting in the second quarter of 2013, its owner Dominion said on Monday. The company said the decision to shutter the plant was based “purely on economics.”

Bruce Power on Tuesday synchronized its Bruce Power Unit 2 to Ontario’s grid, marking a milestone in its program to refurbish Units 1 and 2 at the Bruce A nuclear generating station. The company, which synchronized the 750 MW Bruce A Unit 1 with the grid on Sept. 19, said that first synchronization of Unit 2 will allow it to carry out final planned commissioning activities at the plant.

A bipartisan delegation of lawmakers from Pennsylvania on Monday urged the Environmental Protection Agency (EPA) to consider creating a separate subcategory for power plants that convert coal refuse into energy in its final Mercury and Air Toxics Standards (MATS). Though waste coal plants made an important environmental contribution by reducing coal refuse piles, the hydrochloric acid (HCl) standard in the MATS rule could push them out of business, they said.

A123 Systems, maker of an advanced lithium iron phosphate battery and energy storage systems on Tuesday filed voluntary petitions for reorganization under Chapter 11, as Satcon, a provider of utility-grade power conversion solutions for the renewable energy sector, filed for bankruptcy on Wednesday.

The U.S. Environmental Protection Agency (EPA) extended until Nov. 29 an administrative stay of a federal implementation plan to address regional haze under the Clean Air Act at PNM Resources’ 1,800-MW San Juan Generating Station near Farmington, N.M. The agency’s action last week  gave the utility 45 more days to consider an alternative proposed by the New Mexico Environment Department (NMED), but did  not extend the current September 2016 compliance date of the federal implementation plan.

The owner of one of Victoria’s largest coal-fired power stations announced on Wednesday it would cut output at the Gippsland-based Yallourn power station, saying the July 1-implemented carbon tax is driving up operating costs and that Australia’s renewable energy target is squashing wholesale power prices to uneconomic levels.

Louisville Gas and Electric Co. (LG&E) on Monday said it would shut down three coal units in Kentucky—a total capacity of 563 MW—eight months earlier than originally planned.

The Department of Interior on Friday finalized its Programmatic Environmental Impact Statement (PEIS), establishing an initial set of 17 solar energy zones totaling about 285,000 acres of public lands that will serve as priority areas for commercial-scale solar development. The initiative is part of the Obama administration’s goal to authorize 10,000 MW of renewable power on public lands.

By Kennedy Maize (@kennedymaize) Washington, D.C., 15 October 2012 – Would Republican Mitt Romney be tougher-minded than Barack Obama when it comes to some of the most egregious energy subsidies flowing out of Washington? As election day mercifully approaches, a duo of libertarian energy experts has examined Romney’s rhetoric on energy. They find that “the […]

The Environmental Protection Agency (EPA) on Friday appealed a federal court decision handed down on Aug. 21 that vacated the agency’s July 2011–finalized Cross-State Air Pollution Rule (CSAPR) because, the court said, it violated federal law. The EPA is now seeking a rehearing en banc that would involve all eight judges that serve at the U.S. Court of Appeals for the D.C. Circuit.

Pennsylvania’s Department of Environmental Protection (DEP) on Wednesday issued an air quality plan approval for a project to build the state’s first power plant to run at least partially on locally sourced Marcellus Shale gas. Moxie Energy’s proposed 936-MW plant in Asylum Township, Bradford County, uses two power blocks that will each consist of a combustion gas turbine and a steam turbine.

Czech utility ÄŒEZ on Wednesday told AREVA that a bid submitted to build two new EPR units at the Temelín Nuclear Power Plant—a site that already houses two VVER-1000 reactors built in 2000 and 2003—has been disqualified because it failed to fulfill “some other crucial criteria” defined in the tender. The decision, which AREVA said it would appeal, means only Westinghouse and an AtomStroyExport-led consortium remain as contenders for that project contract.

Global nuclear power capacity is expected to grow nearly 25% from current levels to 456 GW by 2030 according to low projections, International Atomic Energy Agency (IAEA) Director General Yukiya Amano told conference attendees in Kyoto, Japan, on Monday. The Fukushima Daiichi accident was a "big wake-up call" on nuclear safety, but it would not mean "the end of nuclear power," he said as he called on Japan to engage in dialogue about its stated policy to shut down all existing reactors by 2040.
