GE atomic swimmer robot keeps tabs on nuclear reactors

By - August 3, 2015 2 Pictures

One truism of nuclear reactors is that you really don't want to be next to one. Unfortunately, reactor cores need to be inspected and maintained, which means teams of workers going inside the containment vessel. It's an operation that's not only hazardous, but expensive and time consuming. In an effort to make such inspections safer, cheaper, and faster, GE Hitachi Nuclear Energy has developed the Stinger; a free-swimming, remote-controlled robot that replaces humans for cleaning and inspecting reactor vessels.

FDA ticks off first drug to treat radiation sickness after nuclear disasters

By - May 25, 2015 1 Picture

A drug long-used to counter the negative effects of chemotherapy has won US Food and Drug Administration (FDA) approval for use in treating the nasty effects of exposure to radiation following a nuclear disaster. Known commercially as Neupogen, the drug has been shown to work by shielding the body's white blood cells to heighten a patient's chances of survival.

Astronomers detect star leaving the Milky Way at record speeds

By - March 15, 2015 1 Picture
An international team led by astronomers from Queen's University Belfast has identified the fastest ever star on an escape trajectory from the Milky Way – the white dwarf US708, which is traveling at a staggering 1,200 km per sec (746 miles per sec). The discovery of this star may shed light on the astronomical events that are vital to the calculation of distances in our universe. Read More

MINER may help locate hidden nuclear devices in minutes

By - November 2, 2014 1 Picture
It’s been a common trope in films since the 1950s; a madman with an atomic bomb holds a city for ransom while the authorities race to find it in time. If such a thing ever does come about, Sandia National Laboratories is working on taking the suspense out of the situation with its Mobile Imager of Neutrons for Emergency Responders (MINER) – a nuclear device detector capable of narrowing a search to within a city block without door-to-door sweeps.

HMS Artful completes maiden dive

By - October 9, 2014 4 Pictures
With the Royal Navy (RN) working hard to cast off the "Jonah" reputation of its Astute class nuclear attack submarines, BAE Systems has successfully completed the latest RN boat Artful’s maiden dive. The third of the British A boats, which are billed as the most advanced submarine in the world, Artful submerged while tied to the BAE dock at Barrow in Furness, Cumbria as part of its commissioning process.

Newly-discovered waste-eating bacteria could help in nuclear waste disposal

By - September 10, 2014 1 Picture
"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal. Read More

Hitachi developing reactor that burns nuclear waste

By - September 3, 2014 2 Pictures
The problem with nuclear waste is that it needs to be stored for many thousands of years before it’s safe, which is a tricky commitment for even the most stable civilization. To make this situation a bit more manageable, Hitachi, in partnership with MIT, the University of Michigan, and the University of California, Berkeley, is working on new reactor designs that use transuranic nuclear waste for fuel; leaving behind only short-lived radioactive elements.
