Plenty of Progress to Report on Fukushima-related Enhancements

Scott Burnell
Public Affairs Officer

fukushimaThe NRC’s technical staff, industry executives and a public interest group will brief the Commissioners Thursday on the agency’s efforts to implement what we’ve learned from the Fukushima nuclear accident. The bottom line is the NRC is ahead of schedule on several fronts.

Some of the best news involves U.S. reactors meeting requirements from two of the NRC’s Fukushima-related Orders issued in March 2012. By the end of this spring, almost a quarter of the U.S. fleet will comply with the Mitigation Strategies and Spent Fuel Pool Instrumentation Orders. We expect more than half the fleet will meet those Orders by the end of December, which is a full year before the Orders’ deadline.

Every U.S. reactor will comply with the instrumentation requirements by the December 2016 deadline. Every reactor will also comply by that time with a major Mitigation Strategies requirement – additional, well-protected onsite portable equipment to support key safety measures if an extreme event disables a plant’s installed systems. The U.S. industry has already set up two response centers with even more equipment that can be transported to any U.S. reactor within 24 hours. By the time we say good-bye to 2016, almost every reactor will also have made all modifications needed to use those portable systems. In preparing to meet the deadlines, U.S. reactors have already enhanced their ability to keep the public safe.

About a dozen plants will have made all those modifications except changes closely related to the third Order, which requires Hardened Vents for reactors with designs similar to those at Fukushima. These vents would safely relieve pressure in an emergency and help other systems pump cooling water into the core. All the reactors subject to the Order have completed plans for the first set of vent enhancements or installation of new vents.

The NRC staff finished reviewing these plans earlier this month, ahead of schedule, and issued written evaluations to each plant. The agency is also about ready to issue guidance on how these plants can meet the second part of the Order, which involves an additional vent or other methods to protect the structure surrounding the reactor.

The staff’s presentation will also cover topics including revising the NRC’s rules in these areas, as well as the ongoing effort to re-evaluate flooding hazards for all U.S. nuclear power plants. The NRC’s regional offices will provide their perspective on the overall implementation effort’s progress.

Droning On Over Nuclear Power Plants

Monika Coflin
Technical Assistant
Division of Security Policy

Drones, or unmanned aerial vehicles, have been in the news lately. Last fall, unidentified drones breached restricted airspace over 13 of France’s 19 nuclear power plants in a seemingly coordinated fashion. In January, a drone crashed onto the lawn of the White House. And this week, a drone was found on the roof of the Japanese prime minister’s office.

PrintDrones may be fun toys, but they pose a number of concerns. They can be used to conduct surveillance to gather intelligence about facility security. They can also be used to deliver payloads that could include explosives. While the majority of drones currently in use are relatively small, larger ones are becoming available that could possibly deliver payloads capable of causing damage to facilities that are not hardened.

Security experts haven’t yet identified who was responsible for the French flyovers, but with the prices of drones falling and their popularity rising, the potential threat will likely continue to grow.

There are ways to detect and intercept drones, such as jamming radio signals or using helicopters to pursue encroaching drones. Chinese scientists are developing a laser weapon that can detect and shoot down small, low-flying aircraft, and interception drones have the ability to drop nets over intruding drones. However, there are many legal issues that challenge the use of these techniques.

The Federal Aviation Administration (FAA) has a long-standing “Notice to Airmen” warning pilots not to linger over nuclear power plants. The FAA has also issued guidelines on where users should not fly drones, but the industry is largely unregulated as more companies look to use the relatively new technology in their businesses. The FAA has been working to craft a comprehensive regulatory framework for drones, following calls from Congress and the President, and recently issued draft regulations for the commercial use of drones.

PrintPresident Obama likened the drone industry to cyberspace, which has brought new technologies that U.S. laws are still trying to catch up to.

“These technologies that we’re developing have the capacity to empower individuals in ways that we couldn’t even imagine 10-15 years ago,” the President said, pledging to work to create a framework that “ensures that we get the good and minimize the bad.”

Given the evolving nature of technology and the need to balance the threat with the potential benefits of drones, the NRC is actively engaging with the departments of Homeland Security, Energy, and Defense to move this government collaboration effort forward. For example, we have reached out to the FAA to examine available legal and regulatory options, and attended inter-agency meetings to learn about how other agencies are addressing potential impacts from drones.

In addition, NRC will participate in a U.S.-initiated drone working group under the nuclear counterterrorism umbrella with the governments of France and the United Kingdom. The NRC has provided, and will continue to provide, pertinent information on this topic in a timely manner to its licensees to ensure continued safe and secure operations.

Throwback Thursday – The Nuclear Savannah

14698777183_cbe50c4bb1_nNS (Nuclear Ship) Savannah, the first commercial nuclear-powered cargo vessel, is seen here heading to the World’s Fair in Seattle. Built in the late 1950s at a cost of $47 million, including a $28 million nuclear reactor and fuel core, the Savannah was a demonstration project for the potential use of nuclear energy. She was launched in July 1959 and named for the SS Savannah, the first steamship to cross the Atlantic Ocean.

NS Savannah was in service between 1962 and 1972 as one of only four nuclear-powered merchant ships ever built. Anyone know where she is moored today? Photo courtesy of National Archives and Records Administration

Three Minutes with an NRC Health Physicist

Sophie Holiday
Health Physicist

By now most of you have heard of STEM (science, technology, engineering and math) or STEAM (which also includes the arts). These terms are shorthand for the school subjects that experts believe are essential to prepare students for today’s workforce. What may not be as familiar is the range of jobs available to students in STEM fields.

3minutesAt the NRC, we are always looking for students with good STEM backgrounds. But we don’t only hire nuclear engineers. In fact, there are many health physicists as part of our workforce. This important specialty is the subject of one of our latest YouTube videos.

Health physicists are trained in protecting people, members of the public and patients from the potential hazards of using radioactive materials. Radioactive materials can be used in diagnosing and treating illnesses, conducting research, producing electricity or any number of industrial processes. Besides physics, health physicists might study biology, health, engineering, technology or environmental science.

At the NRC, health physicists fill a variety of roles. They review applications for new reactors and amendments to existing reactors. They make sure our regulations will be met by facilities involved in processing uranium into nuclear fuel. They oversee the safety of medical, academic and industrial uses of radioisotopes. They perform inspections at the facilities we license. Health physicists are essential to fulfilling the NRC’s mission of protecting people and the environment.

Check out our video to learn more about the important role health physicists play in our society.
