How X-rays in matter create genetoxic low-energy electrons

Sendai, Japan (SPX) Feb 01, 2017

Researchers led by Kiyoshi Ueda of Tohoku University have investigated what x-rays in matter really do and identified a new mechanism of producing low-energy free electrons. Since the low-energy electrons cause damage to the matter, the identified process might be important in understanding and designing radiation treatment of illnesses.

X-rays are one of the most important diagnostic tool

Radiation level in Fukushima plant at record high

Tokyo (AFP) Feb 3, 2017

/>
Radiation levels inside a stricken reactor at Japan's Fukushima nuclear plant have hit a record high capable of shutting down robots, in the latest challenge to efforts aimed at dismantling the disaster-hit facility.

Radiation levels inside the plant's No. 2 reactor were estimated at 530 sieverts per hour at one spot, Tokyo Electric Power Co (TEPCO) said Thursday after analysing images t

Fukushima operator eyes plan to clean up plant

Fukushima Daiichi Nuclear Plant, Japan (AFP) Feb 23, 2017

The operator of Japan's stricken Fukushima nuclear plant said Thursday it will craft a plan this summer to extract highly radioactive fuel from the damaged reactors - a key step in decommissioning work expected to take decades.

Operator Tokyo Electric Power Co (TEPCO) and the Japanese government have struggled to clean up the world's worst nuclear accident since Chernobyl in 1986.

German energy giant RWE posts 5.7-bln-euro loss in 2016

Frankfurt Am Main (AFP) Feb 22, 2017

German energy provider RWE on Thursday announced a surprise loss of 5.7 billion euros for 2016, hit by writedowns on its plants and one-off costs related to the country's exit from nuclear power.

"The difficult market environment made impairments necessary. In addition, the nuclear energy fund imposed a substantial one-off burden on us," chief executive Rolf Martin Schmitz said in an unsched

Russia's Rosatom Subsidiaries Produced 7,900 Tonnes of Uranium in 2016

Moscow (Sputnik) Feb 22, 2017

Russian state-owned nuclear energy corporation Rosatom's subsidiaries produced the total of 7,900 metric tons of uranium in 2016, which is on the 2015 level, the company said Monday.

"Uranium production: 7,900 tonnes (including 4,900 tonnes produced abroad)," the company said on its website, which also indicates that Rosatom's uranium production amounted to 7,900 metric tons in 2015 as wel

China delays nuclear reactor start again

Paris (AFP) Feb 21, 2017

Two nuclear reactors being built in the southern Chinese city of Taishan will come onstream months later than planned, said China General Nuclear Power (CGN), which runs the project together with France's EDF.

"Taishan Nuclear recently organised a comprehensive evaluation on subsequent engineering construction plan and relevant risks, and after due consideration, it is decided to adjust the

System automatically detects cracks in nuclear power plants

West Lafayette IN (SPX) Feb 21, 2017

A new automated system detects cracks in the steel components of nuclear power plants and has been shown to be more accurate than other automated systems. "Periodic inspection of the components of nuclear power plants is important to avoid accidents and ensure safe operation," said Mohammad R. Jahanshahi, an assistant professor in Purdue University's Lyles School of Civil Engineering.

New synchrotron powder diffraction facility for long running experiments

London, UK (SPX) Feb 17, 2017

Synchrotron beamlines and their instruments are built to harness the photon beam power of synchrotron radiation (SR), which has special properties - ideally suited to providing detailed and accurate structural information that is difficult to obtain from conventional sources. The common modus operandi for such facilities is that users are allocated a short duration of beamtime, typically a few h

Slovenian nuclear plant restarts after shutdown

Ljubljana (AFP) Feb 17, 2017

A 35-year-old nuclear plant in Slovenia was restarted Friday after it automatically shut down because of a water supply problem, its operator said.

"The unexpected malfunction was fixed... After thorough testing, the power plant was restarted and reconnected to the system," the Krsko nuclear plant said in a statement.

The facility in Krsko, some 100 kilometres (60 miles) east of the capi

'Scorpion' robot mission inside Fukushima reactor aborted

Tokyo (AFP) Feb 16, 2017

A "scorpion" robot sent into a Japanese nuclear reactor to learn about the damage suffered in a tsunami-induced meltdown had its mission aborted after the probe ran into trouble, Tokyo Electric Power company said Thursday.

TEPCO, the operator of the Fukushima nuclear plant, sent the remote-controlled device into the No. 2 reactor where radiation levels have recently hit record highs.
