Hazy Timetable for EPA’s Proposed Tighter PM2.5 Standards
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 Evolution of Steam Attemperation
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.

Top Plant: North Anna Power Station, Louisa County, Virginia
In 2007, Dominion Resources contracted Alstom to perform steam turbine retrofits on two generating units at its North Anna nuclear power station. The Unit 1 retrofit, with its ongoing instrumentation upgrade, was the second to be completed at the North Anna plant and the fourth overall for Dominion. Completion of this project marked a significant milestone in terms of both technical achievement and investment in providing clean, safe, and reliable baseload electricity for Dominion customers.

Economic Meltdown
The bill for German Chancellor Angela Merkel’s coalition government’s knee-jerk decision to close all 17 of its nuclear plants by 2022 is coming due. Merkel’s energy plan is to radically expand the use of renewable energy to 35% of total power consumption by 2020 and to 80% by 2050. Currently, renewables represent 20% of the country’s energy mix.

France Considers Departure from Iconic Stance on Nuclear Energy
No other country has been as frequently cited as an example of exploiting the virtues of a nuclear-heavy energy policy as France. Deriving more than 75% of its electricity from 58 operational nuclear reactors with a total capacity of about 63 GW, France has one of the lowest costs of generation and is the world’s largest net exporter of power, earning €3 billion ($3.9 billion) a year from sales of surplus power to buyers beyond its borders. But that is all about to change.

Dominion’s North Anna Station Sets New Standard for Earthquake Response
On August 23, 2011, at 1:51 p.m., a magnitude 5.8 earthquake knocked both units at Dominion’s North Anna Power Station off-line—the first time such an event has occurred in the U.S. After 80 days of extensive evaluation and inspection by plant staff and representatives from the U.S. Nuclear Regulatory Commission, both units were back online. What occurred during those days is a remarkable story.

Coal Burn Rebounds in the Third Quarter, but Economics Still Favor Natural Gas
