Prude University has developed a wearable badge that can detect radiation immediately using yeast. "Most of the wearable radiation dosimeters are involved with silicon fabrication, which is expensive as compared to this approach," says College of Engineering graduate student and researcher Jiawei Zhou.
Washington University in St. Louis researchers are part of the Center for Excellence in Nuclear Training and University's research program developing a neutron detection computer chip to help detect illegal nuclear material transports. "The problem with existing neutron detectors is that they are too big to get fine position information," says professor Lee Sobotka.
Coupling seismic activity with antineutrino detection could help identify nuclear weapons testing, reports a study in Physical Review Applied. Analyzing neutrinos may also help determine the type of nuclear weapon involved.
Commentary in a North Korean state-run newspaper has confirmed that US officials confronted the country about continued nuclear weapons development despite denuclearization talks. The state paper suggests that President Donald Trump and Secretary of State Mike Pompeo should take a relaxed approach to denuclearization and move away from White House national security adviser John Bolton's hard-line approach to ensure talks progress.
The California state legislature has passed a bill to help ease the financial effect of the closure of PG&E's Diablo Canyon Nuclear Power Plant. The bill will result in a 0.2% average increase in customer's monthly bills, says PG&E spokesperson Blair Jones.
Two recent used fuel transfer incidents at the San Onofre Nuclear Generating Station did not put the public at risk. However, the plant's chief nuclear operator, Tom Palmisano, said it was "unacceptable" and has suspended the transfer of remaining used fuel pending procedural review.
To address shutdowns of nuclear reactors in Sweden due to hot weather, the country's nuclear regulator, SSM, has solicited operators for methods to protect reactors from the heat. The regulator hopes to have the plans by year-end, says SSM executive Mats Persson.
EDF has delayed the restart of its Nogent-1 reactor until mid-September after previously expecting only a two-day shutdown, one of a series of setbacks that have reduced France's nuclear power capacity by 9 GW. The company's Saint Alban-2 reactor continues to see limited production due to high river water temperatures.
This month's Santee Cooper board meeting has been delayed while South Carolina Gov. Henry McMaster battles with the state Senate over who should be the board's chairman. McMaster has been pushing to sell the utility following the failed V.C. Summer project.
The Nuclear Regulatory Commission says it has gained "reasonable assurance" that the Seabrook Nuclear Power Plant in New Hampshire is addressing cracks in concrete as plant owner NextEra seeks to extend its license through 2050. NRC said its inspection showed the plant is seeking to protect the public from the cracks, which are caused by a chemical reaction that causes the concrete to expand and crack.
