Mystery of coronal heating problem: Magnetically driven resonance helps heat sun's atmosphere

Solar physicists have captured the first direct observational signatures of resonant absorption, thought to play an important role in solving the ‘coronal heating problem’ which has defied explanation for over 70 years. An international research team combined high resolution observations from JAXA’s Hinode and NASA’s IRIS mission, together with state-of-the-art numerical simulations and modeling from NAOJ’s ATERUI supercomputer. In the combined data, they were able to detect and identify the observational signatures of resonant absorption.

Sendai Reactor Power Ramp-Up Halted Due To Pump Problem

By Broc West

via news.yahoo.com / August 21, 2015 / Japan’s Kyushu Electric Power has halted the ramp-up of power output from its Sendai No. 1 nuclear reactor due to a problem with a pump in the plant’s secondary cooling system, a spokesman said on Friday. Kyushu Electric last week began the restart of the Sendai plant, the first of Japan’s reactors to begin operation under new safety standards introduced in the wake … Continue reading

Proving Negligence in TEPCO Case Daunting

By Broc West

By Kunihiko Yoshizawa and Toru Asami / via The-Japan-News.com / August 22, 2015 / On July 31, the Tokyo No. 5 Committee for the Inquest of Prosecution announced its decision that former Tokyo Electric Power Co. Chairman Tsunehisa Katsumata (pictured), 75, and two other former company executives “should be indicted” in connection with the Fukushima No. 1 nuclear power plant disaster. In this case the “will of the people” has … Continue reading

Fukushima: Thousands Have Already Died, Thousands More Will Die

By Broc West

by Ian Fairlie CounterPunch.org August 20, 2015 Official data from Fukushima show that nearly 2,000 people died from the effects of evacuations necessary to avoid high radiation exposures from the disaster. The uprooting to unfamiliar areas, cutting of family ties, loss of social support networks, disruption, exhaustion, poor physical conditions and disorientation can and do result in many people, in particular older people, dying. Increased suicide has occurred among younger … Continue reading

Sakurajima Volcano: Chance of Large Eruption ‘Extremely High’

By Broc West

August 15, 2015 via TheGuardian.co.uk Japan’s weather agency on Saturday told thousands of residents near a southern city to prepare for a possible evacuation as it upgraded a volcanic eruption warning. Officials raised their alert to its second-highest level after picking up increasing seismic activity around the volcano Sakurajima, which sits just off the coast of Kagoshima, a city of more than 600,000 people. Activity has spiked since Saturday morning, … Continue reading

Large Protests As Japan Restarts First Nuclear Plant Since Fukushima

By Broc West

via RT.com / August 11, 2015 / Protesters rallied outside Japan’s Sendai nuclear plant and its company’s headquarters to demonstrate against the planned restarting of operations, over four years after the Fukushima disaster that left the entire world horrified. One major concern about the resumption is that no evacuation plans – in case of a Fukushima-style catastrophe – have been disclosed to locals. “There are schools and hospitals near the … Continue reading

Fukushima – Selling Out the Next Generation

By Broc West

via Truth Out / August 11, 2015 / Japan has restarted its first nuclear reactor to generate power since 2013. And that’s really bad news. Remember what happened in 2011? Why Japan closed all of its reactors abruptly and why we’re still tracing the spread of radioactive material across our Pacific Coast and into the atmosphere? First there was an earthquake that did significant damage to that island country – … Continue reading

Japan Ends Nuclear Shutdown Four Years After Fukushima

By Broc West

via Phys.org / August 11, 2015 / Japan on Tuesday ended a two-year nuclear shutdown in the energy-hungry country, sparked by public fears following the 2011 Fukushima crisis, the worst atomic disaster in a generation. Utility Kyushu Electric Power turned on a reactor at Sendai, about 1,000 kilometres (620 miles) southwest of Tokyo, at 10:30 am (0130 GMT). The 31-year-old reactor—operating under tougher post-Fukushima safety rules—was expected to reach full … Continue reading

New tools for predicting arrival, impact of solar storms

When the sun hurls a billion tons of high-energy particles and magnetic fields into space at speeds of more than a million miles per hour and the ‘space weather’ conditions are right, the resulting geomagnetic storm at Earth can wreak havoc on communication and navigation systems, electrical power grids, and pose radiation hazards to astronauts and airline passengers and crew.
