On nuclear waste bill, senators look to public for help

07/01/13 New York Times — A pending Senate bill would solicit input from the public about where to bury the nation's nuclear waste. Per F. Peterson, professor of nuclear engineering, praised the action as "something highly unusual" in the creation of public policy that "establishes a strong foundation for the legislation to be successful" if passed by Congress.

Washington calling

05/01/12 — The White House has tapped two of Berkeley Engineering's own for leadership on critical presidential initiatives.

Berkeley leadership on America’s nuclear future

03/19/12 — With America's nuclear waste management program at an impasse, we have been anxiously awaiting word from President Obama's Blue Ribbon Commission on America's Nuclear Future-with Berkeley's Nuclear Engineering Chair Per Peterson among its 15 distinguished members-on how to break the deadlock.

$7.5 million DOE grant will help develop new generation of advanced reactors

09/22/11 Massachusetts Institute of Technology — MIT has been awarded $7.5 million as part of a new initiative by the Department of Energy to support research and development on the next generation of nuclear technologies. The Integrated Research Projects were established to help ensure that the country maintains a leading role in nuclear energy research. The Department of Nuclear Science and Engineering and the MIT Reactor Lab will work together with their partners at the University of California at Berkeley and the University of Wisconsin at Madison on the project over the next three years to develop the path forward to a test reactor and ultimately a commercial high-temperature salt-cooled reactor.

An engineer’s duty

04/08/11 — When disaster strikes, all of us feel compelled to respond. Japan's devastating earthquake on March 11 called forth our faculty and students to help in ways only an engineer can.

On West Coast of U.S., much ado about very little radiation, so far

03/19/11 Los Angeles Times — U.S. scientists and sensors are poised to detect radioactive fallout from Japan's nuclear accident, but aside from a 'minuscule' amount at a Sacramento station, they've found none. The nuclear engineering department at UC Berkeley set up its own independent monitoring Wednesday on top of the campus' Etcheverry Hall. The system looks for gamma rays with energy "signatures" corresponding to radioactive isotopes, said Kai Vetter, a professor in the department. As of Friday morning, Vetter said, they hadn't seen any evidence of suspicious radiation.

Options are few to prevent Japan nuclear catastrophe

03/18/11 Los Angeles Times — As a crack is discovered in a Fukushima spent fuel pool, officials confront two crucial tasks: preventing a runaway chain reaction into the nuclear fuel and maintaining a massive flow of seawater through the damaged pools and reactor vessels. Edward Morse and Per Peterson of UC Berkeley's Department of Nuclear Engineering offer analysis.

Radioactive particles arriving in the Bay Area, but pose no risk, say UC scientists and health officials

03/18/11 San Jose Mercury News — While public health officials downplayed fears that a plume from Japan's crippled nuclear reactors was descending on California, scientists at UC Berkeley declared they were already detecting radioactive particles from 5,000 miles across the ocean. The differing accounts illustrated the confusion on the fallout from Japan's crisis, but scientists and public health experts agreed that whatever radiation may drift to California and the West Coast will be too minuscule to pose any health risks. "We see evidence of fission particles -- iodine, cesium, barium and krypton, a whole dog's breakfast of radiation," said Ed Morse, professor of nuclear engineering at UC Berkeley, whose students have set up a monitor on the rooftop of the campus's Etcheverry Building.

Atomic fuel stored at U.S. plants poses risks similar to Japan facilities

03/18/11 Bloomberg — U.S. nuclear power plants that store thousands of metric tons of spent atomic fuel pose risks of a crisis like the one unfolding in Japan, where crews are battling to prevent a meltdown of stored fuel, nuclear safety experts said. Nuclear plants weren't designed with the intention of storing their spent fuel permanently, said Bozidar Stojadinovic, a professor in the department of civil and environmental engineering at UC Berkeley. "The plants have always been designed with the idea that the fuel will be taken care of," Stojadinovic said. "The government promised to do that."

Japan’s nuclear crisis

03/15/11 KQED Forum — As Japan struggles to contain the worst nuclear emergency since Chernobyl, Michael Krasny talks with experts including Per Peterson, chair of the Nuclear Engineering Department at UC Berkeley, about the potential fallout from the nuclear reactors in Fukushima.

Japan nuclear reactor different from Chernobyl, UC Berkeley’s Olander says

03/15/11 Bloomberg — UC Berkeley nuclear engineering professor Don Olander said the damage to nuclear plants in Japan after an earthquake is different from the disaster at Chernobyl in the Ukraine in 1986. "This is a reactor which has two containments...If that is intact, if the melt has not gone through the bottom, then most of the fission products will stay inside. Chernobyl did not have that protection. Chernobyl was open and the entire core was destroyed."

Japan works to contain nuclear reactor meltdowns

03/14/11 San Francisco Chronicle — As Japanese nuclear engineers struggled to contain partial meltdowns of two major nuclear power reactors in the wake of an earthquake and tsunami, experts in the United States said Sunday that a similar disaster would be highly unlikely here. Fifty-four power reactors regularly supply electricity throughout Japan, and the crisis represents "an incredibly rare worst-case disaster," said Jasmina Vujic, a professor of nuclear engineering at UC Berkeley and a specialist in the design of reactor cores and radiation protection.

UC Berkeley engineers concerned about reactor leak

03/12/11 ABC News — States of emergency are in effect at five nuclear power plants in Japan. Evacuations are underway as the concern grows about the possibility of a nuclear meltdown. Berkeley nuclear engineers say the Fukushima Daiichi power plant, which is now shut down, is about 40 years old. "This increase of radioactivity in the control room makes me very nervous," said UC Berkeley nuclear engineering professor Joonhong Ahn, who was born in Japan.

UC Berkeley nuclear engineering team to lead National Science and Security Consortium

03/07/11 — A UC Berkeley-led consortium of seven universities has been awarded a multi-year grant ($25 million for a 5-year period) from the U.S. Department of Energy NNSA Office of Proliferation Detection. The consortium will largely focus on education and hands-on training of undergraduate and graduate students in the core set of experimental disciplines that support the nation's non-proliferation and nuclear security mission: nuclear physics, nuclear chemistry, nuclear instrumentation, and nuclear engineering.

Rethinking nuclear power

04/07/10 — What's the first thing you think of when you hear the word nuclear? Mushroom clouds? Three Mile Island's reactor towers surrounded by swirling steam? Think again. Nuclear is back, big time. With climate change concerns escalating, fossil fuel supplies diminishing and electricity consumption expected to double in 10 years, nuclear has regained some of its lost luster. According to Brian Wirth, associate professor of nuclear engineering, “The 104 nuclear plants now in operation represent the largest source of carbon-free electricity in the country.”

Blue and gold make green in Silicon Valley

04/07/10 — Clean and green technologies are on the rise in Silicon Valley. Electric car startups like Tesla Motors and solar cell and biofuel innovators are snapping up commercial space, while established companies like Applied Materials are growing their clean energy divisions. “Over the past six years, clean tech's portion of venture [capital] investments has grown from merely 3 percent to more than 25 percent,” reported the San Jose Mercury News in January. The newspaper went on to pronounce clean and green technologies the next great wave of innovation in Silicon Valley. It's no surprise to five Berkeley Engineering alumni who work in the up-and-coming sector.

Thomas H. Pigford, nuclear engineer, is dead at 87

03/04/10 The New York Times — Thomas H. Pigford, an independent-minded nuclear engineer who was recruited by the federal government for his advice on major nuclear accidents and nuclear waste, died Saturday at his home in Oakland. Dr. Pigford was the first chairman of the nuclear engineering department at UC Berkeley. Before going to Berkeley, Dr. Pigford helped establish the nuclear engineering department at M.I.T. A chemical engineer, Dr. Pigford helped develop the process used by the government for years to harvest plutonium for bombs from irradiated reactor fuel. He was a co-author of "Nuclear Chemical Engineering," published in 1958 and considered the first text in the field.
