LIDAR and 3D Modeling Produce Precise Designs
Retrofit projects are often very time-consuming, both for the engineers who must take numerous field measurements to produce drawings and for the contractor that must fabricate each assembly on site. A more cost-effective approach is to begin with a highly accurate set of as-built 3D models produced by laser scanning technology.

Trend Shows Growth of Renewables on Contaminated Lands
Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

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.

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.

Potential Impacts of Closed-Cycle Cooling Retrofits at U.S. Power Plants
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.

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.

Even with implementation delays, now is a good time to start paying closer attention to the requirements of the proposed standard.

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.

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.
