Exelon Nuclear has added seven mobile, high-volume diesel-driven pumps at its nuclear energy facilities, among thousands of equipment purchases, upgrades, and validations completed at Exelon’s 10 plants in the year following the tragic earthquake and tsunami in Japan.

Exelon technical experts have verified readiness of more than 1,700 other pieces of equipment; inspected more than 1,900 flood barriers and seals; and invested more than 43,000 worker hours checking and testing equipment and procedures that might be needed in an emergency.

“We have a responsibility to communicate what we are doing as a company to learn from the lessons following the tragedy in Japan and we take that responsibility seriously. Our top priority is to assure the continued safe and reliable production of electricity at our nuclear facilities in Illinois, Pennsylvania, and New Jersey,” said Mike Pacilio, president and chief nuclear officer of Exelon Nuclear.

“Since last March, we have taken the learnings from Fukushima, critically assessed our operations and taken immediate actions,” he said. “We have additional safety measures planned for Exelon and the entire U.S. nuclear industry in the months ahead with additional guidance being issued by the U.S. Nuclear Regulatory Commission. It is critical that we always be a learning organization dedicated to the safety of our facilities.”

The completed actions represent just a portion of the inspections, upgrades, and other work undertaken by Exelon Nuclear following the Fukushima-Daiichi disaster. The company operates the largest fleet of commercial nuclear facilities in the U.S., with 17 reactors at 10 sites.

Within a week of the March 11, 2011, events, teams of engineers and technical experts from Exelon Nuclear and others in the industry traveled to Japan to provide expertise and to begin understanding as many lessons as possible from the experience. The primary lesson: expect the unexpected, and prepare for the unimaginable.

Learnings from Fukushima have translated into extensive reviews of equipment, structures, and procedures; purchases of additional backup emergency equipment; updates of emergency procedures; and additions to emergency training. At Exelon, the overriding goal is to reaffirm that its nuclear facilities and the professionals who operate and maintain them are prepared to deal with even the most severe unpredictable events.

Among other tasks completed over the past 12 months, Exelon Nuclear engineers and experts have:

• Revised more than 1,300 safety procedures and guidelines, and created new ones, based on Fukushima lessons.
• Verified the capability of all sites to withstand the most severe floods for their areas, and are in the process of re-evaluating base assumptions about maximum historical flooding.
• Broadened operator training to incorporate lessons from Fukushima.
• Inspected and validated the seismic supports and restraints for thousands of pieces of equipment and pipes.

Beyond the actions listed, in February of 2012, Exelon and the other U.S. nuclear operating companies unanimously agreed to purchase or order additional safety equipment for their plants by March 31. This includes emergency and portable equipment such as diesel driven pumps, electric generators, hoses, fittings, communications gear, and other equipment.

Well before the events at Fukushima, Exelon Nuclear facilities had multiple physical barriers and layers of backup safety systems to ensure safe operations even in extreme events, including floods, hurricanes, tornadoes, and earthquakes. Equipment purchases and work over the past year has strengthened those barriers and systems, and enhancements will continue for years.

All Exelon Nuclear facilities are protected from flooding by watertight doors, elevation of equipment above flood levels and specially engineered flood barriers. All sites can automatically and safely shut down and keep the fuel cooled even without electricity from the grid, using massive backup power generators that have second, third and fourth layers of backups. Reactors and other critical components are protected by concrete walls up to five-feet thick. All facilities undergo frequent emergency training and exercises involving government emergency response agencies at all levels.

Exelon Nuclear’s emergency operating procedures are constantly tested, challenged, and simulated to ensure that they will work properly when needed. Such drills are overseen by the NRC with NRC inspectors stationed at all U.S. nuclear facilities on a full–time basis.

Over the last twelve months, the U.S. nuclear industry has pooled resources to ensure the lessons fromJapan are systematically gathered, analyzed, and implemented. The process identified short and long-term actions that further increase the margin of safety at U.S. nuclear facilities.

“Exelon Nuclear is dedicated to full transparency,” said Pacilio. “We know that the more the public knows about the safety of the U.S. nuclear industry, the more confident they feel about nuclear power as a source of safe, abundant, and clean energy.”

The article American Nuclear Society to Release Special Report on Fukushima appeared first on The Toonari Post - News, Powered by the People!.

An estimated 14,000 excess deaths in the United States are linked to the radioactive fallout from the disaster at the Fukushima nuclear reactors in Japan, according to a major new article in the December 2011 edition of the International Journal of Health Services.

This is the first peer-reviewed study published in a medical journal documenting the health hazards of Fukushima.

Authors Joseph Mangano and Janette Sherman note that their estimate of 14,000 excess U.S. deaths in the 14 weeks after the Fukushima meltdowns is comparable to the 16,500 excess deaths in the 17 weeks after the Chernobyl meltdown in 1986. The rise in reported deaths after Fukushima was largest among U.S. infants under age one. The 2010-2011 increase for infant deaths in the spring was 1.8 percent, compared to a decrease of 8.37 percent in the preceding 14 weeks.

The IJHS article is available at http://www.radiation.org.

Just six days after the disastrous meltdowns struck four reactors at Fukushima on March 11, scientists detected the plume of toxic fallout had arrived over American shores.  Subsequent measurements by the U.S. Environmental Protection Agency (EPA) found levels of radiation in air, water, and milk hundreds of times above normal across the U.S.  The highest detected levels of Iodine-131 in precipitation in the U.S. were as follows (normal is about 2 picocuries I-131 per liter of water):  Boise, ID (390); Kansas City (200);Salt Lake City (190); Jacksonville, FL (150); Olympia, WA (125); and Boston, MA (92).

Epidemiologist Joseph Mangano, MPH MBA, said: ”This study of Fukushima health hazards is the first to be published in a scientific journal.  It raises concerns, and strongly suggests that health studies continue, to understand the true impact of Fukushima in Japan and around the world.  Findings are important to the current debate of whether to build new reactors, and how long to keep aging ones in operation.”

Mangano is executive director, Radiation and Public Health Project, and the author of 27 peer-reviewed medical journal articles and letters.

Internist and toxicologist Janette Sherman, MD, said: ”Based on our continuing research, the actual death count here may be as high as 18,000, with influenza and pneumonia, which were up five-fold in the period in question as a cause of death. Deaths are seen across all ages, but we continue to find that infants are hardest hit because their tissues are rapidly multiplying, they have undeveloped immune systems, and the doses of radioisotopes are proportionally greater than for adults.”

Dr. Sherman is an adjunct professor, Western Michigan University, and contributing editor of ”Chernobyl – Consequences of the Catastrophe for People and the Environment” published by the NY Academy of Sciences in 2009, and author of ”Chemical Exposure and Disease and Life’s Delicate Balance – Causes and Prevention of Breast Cancer.”

The Centers for Disease Control and Prevention (CDC) issues weekly reports on numbers of deaths for 122 U.S. cities with a population over 100,000, or about 25-30 percent of the U.S.  In the 14 weeks after Fukushima fallout arrived in the U.S. (March 20 to June 25), deaths reported to the CDC rose 4.46 percent from the same period in 2010, compared to just 2.34 percent in the 14 weeks prior. Estimated excess deaths during this period for the entire U.S. are about 14,000.
