Progress Energy implementing post-Fukushima lessons learned

RALEIGH, N.C. (March 8, 2012) – In the year since the tsunamis that caused accidents at nuclear power plants in Fukushima, Japan, Progress Energy has worked with the U.S. nuclear industry, the Nuclear Energy Institute and global resources to understand the events and implement changes to make the company’s plants even safer and better protected.

The company’s response includes in-depth inspections and analyses, physical changes, additional equipment to monitor and respond to potential emergencies, and plans for additional safety and security initiatives.

Progress Energy Chief Nuclear Officer James Scarola has been named as a special liaison for the U.S. nuclear industry’s Fukushima response. In that role, Scarola is helping lead the continuing effort to analyze lessons learned from the Fukushima events and response, and work with regulatory agencies, the industry and other stakeholders to implement enhancement plans at each of the nation’s 104 commercial nuclear plants.

Immediately following the March 11, 2011, accident at Fukushima Daiichi, Progress Energy conducted thorough inspections at each of its four nuclear sites located in the Carolinas and Florida. Plant personnel reviewed each plant’s emergency-response capabilities, written procedures and engineering specifications to verify each site’s ability to respond in the unlikely event of station blackout or record flood.

In 2012, Progress Energy is working to establish industry best practices and improve the safety standards and margin. The U.S. approach to safety at nuclear power plants is based on three layers of safety: protection, mitigation and emergency response. A revised strategy represents a significant expansion of the second layer — the ability to protect the plant and public in extreme external events that may exceed those for which the plant was designed.

Meanwhile, the nuclear industry is in the process of reanalyzing natural disasters, including earthquakes and flooding, to assess the state of readiness in light of the Japan events. U.S. nuclear companies are also adding emergency equipment, such as portable pumps and generators, to perform key safety functions if off-site electrical supplies and several backup power sources are lost to permanently installed safety systems due to natural and/or man-made causes.

Among the additional pieces of equipment, Progress Energy is adding, at each station, a high-capacity pump to maintain the ability to cool the reactor core in an unlikely accident, additional diesel generators for power restoration to critical equipment, and other associated support components (i.e., lights, fans, small generators, direct-current power supplies, pre-staged tool kits, fuel transfer equipment, hoses, cords, fittings, etc.). These systems and pieces of equipment are in addition to the numerous layers of safety measures and systems previously in place.

“At Progress Energy, we are committed to the relentless pursuit of safety,” Scarola said. “We know we need to learn every possible lesson from Japan, and apply those lessons in our quest for continuous improvement. While our nuclear power plants are built to the highest standards, it’s our job to continue to raise those standards by learning from Fukushima — just as we have from best practices and past challenges alike. While there are numerous studies that have validated the safety of our U.S. nuclear plants, our commitment is to make the future operation even safer than it is today.”

Progress Energy (NYSE: PGN), headquartered in Raleigh, N.C., is a Fortune 500 energy company with 23,000 megawatts of generation capacity and approximately $9 billion in annual revenues. Progress Energy includes two major electric utilities that serve about 3.1 million customers in the Carolinas and Florida. The company has earned the Edison Electric Institute's Edison Award, the industry's highest honor, in recognition of its operational excellence, and was the first utility to receive the prestigious J.D. Power and Associates Founder's Award for customer service. The company is pursuing a balanced strategy for a secure energy future, which includes aggressive energy-efficiency programs, investments in renewable energy technologies and a state-of-the-art electricity system. Progress Energy celebrated a century of service in 2008. Visit the company’s website at www.progress-energy.com.

Utility to Purchase Low-Carbon Power from Innovative Clean Coal Plant

Carbon emissions for this plant will be...

• less than 10 percent of a conventional coal plant of similar output.
• less than 25 percent of an high-efficiency natural gas-powered power plant.

The Department of Energy is working with industry to keep the United States at the forefront of carbon capture, utilization, and storage technologies. An innovative clean coal demonstration project in Texas, supported by the Department’s Office of Fossil Energy, recently took a big step forward.  

The Energy Department announced that CPS Energy of San Antonio will purchase approximately 200 megawatts of power annually from the Texas Clean Energy Project (TCEP) when the facility is complete in 2015. The $2.4 billion plant will receive $450 million in funding from the Department’s Clean Coal Power Initiative; of this, $211 million comes from the American Recovery and Reinvestment Act.
This is the first purchase in the United States of low-carbon power from a power plant that uses carbon capture technology.

When operational, the 400-MW facility located just west of Midland-Odessa, Texas, will be the cleanest coal-fueled power plant in the world. Using a state-of-the-art process known as integrated gasification combined cycle (IGCC), the total amount of carbon dioxide emitted into the atmosphere from this plant will be less than 10 percent of a conventional coal plant with similar energy output, and less than 25 percent of a high-efficiency natural gas-powered power plant.

It will also be capable of capturing 90 percent of the carbon dioxide (CO₂) it produces, as well as 99 percent of sulfur dioxide, 90 percent of nitrogen oxide, and 99 percent of mercury.

In the gasification process, coal is not burned as if you were shoveling coal into a furnace or a steam locomotive boiler. Instead, the coal is sealed in a gasifier -- an airtight chamber that allows only controlled amounts of oxygen to enter. Starved for oxygen, the coal bakes rather than ignites and creates enough heat and pressure in the chamber to squeeze hydrogen and carbon monoxide out of the coal. The gases squeezed from the coal are then processed into synthetic gas, or syngas.

Next, water vapor is added to the syngas, which chemically reacts with the carbon monoxide to create additional hydrogen and also carbon dioxide. The gas is then cleaned of impurities, and separated into pure streams of hydrogen and carbon dioxide. The hydrogen powers an advanced turbine to generate electricity and its carbon-free exhaust heats water to generate steam that’s fed to a turbine to produce even more electricity.

Of the nearly 2.9 million metric tons of carbon dioxide to be captured annually at the Texas plant, 83 percent will be used in the West Texas Permian Basin for enhanced oil recovery -- a technique where carbon dioxide is pumped into a known reservoir where it expands and forces the oil out of the well. The rest of the captured carbon dioxide will go to producing urea -- a valuable compound with many industrial applications.

Today, approximately 80 percent of the energy consumed in the United States comes from coal, petroleum, and natural gas, with coal-fired power plants accounting for approximately half of the electricity generated. The implementation of clean, state-of-the-art coal-based technologies will help ensure America’s energy security while mitigating the environmental impacts of fossil fuel use.
