Nuclear Power Whistleblowers Charge Federal Regulators With Favoring Secrecy Over Safety Richard H. Perkins and Larry Criscione are precise and formal men with more than 20 years of combined government and military service. Perkins held posts at the Department of Energy and the National Nuclear Security Administration before joining the Nuclear Regulatory Commission's Division of Risk Analysis in 2008. Criscione landed at the agency a year later, after five years aboard the USS Georgia as a submarine warfare officer. Now both men are also reluctant whistleblowers, stepping out publicly to accuse the NRC of being both disconcertingly sluggish and inappropriately secretive about severe -- and in one case, potentially catastrophic -- flood risks at nuclear plants that sit downstream from large dams.

Aftershocks — as many as 12 to 15 an hour — now total in the hundreds, including more than 30 of magnitude 6 or greater. Play the timeline map below to see quakes magnitude 5 and greater before and after the strongest temblor to strike Japan in 140 years.

Fukushima Nuclear Accident – a simple and accurate explanation Editors' Note: this post was written by a person who knew of nuclear physics but was not a nuclear engineer nor physicist, but an economist. This content has now been edited for accuracy by the MIT scientific community. Below is an updated version of the original post written by Josef Oehmen. This post originally appeared on Morgsatlarge. The Historic Records Show that Nuclear Authorities Know the Fallacy of their Current Position In progress. This post compares the situation as documented by Dennis Heyden last post – that evidence showing a multiplier effect for internal emitters compared to external exposure readings is dismissed – with the early record which for the first time proved the multiplier effect does indeed exist. The very grave observations held by expert researchers made of the actions specific to internal emitters have not be contradicted by any later observations. And these early papers have not been contradicted by any later point by point rebuttal based upon evidence gained by observation.

De l'inde à De l'Asie à l'Europe : le nucléaire remis en question All India | Noopur Tiwari | Updated: March 15, 2011 23:43 IST Paris/New Delhi: Experts say the Fukushima nuclear disaster could be Level 6, just one notch below the Chernobyl disaster. As Japan tries desperately to control the damage, government's across the world are now stepping up efforts to assess how safe their own nuclear reactors are. And that includes India, which will see French EPR reactors being installed at Jaitapur in Maharashtra soon. Prime Minister Manmohan Singh has made a detailed statement in Parliament and has ordered a review of safety systems at all the nuclear plants in the country.

ABC News - Japan Earthquake: before and after Development: Andrew KesperSource: Google Aerial photos taken over Japan have revealed the scale of devastation across dozens of suburbs and tens of thousands of homes and businesses. Hover over each satellite photo to view the devastation caused by the earthquake and tsunami. Sendai Airport Japan's disaster compounded by dwindling supplies for survivors, nuclear emergency A series of unstable nuclear plants across the country threatened to compound the nation’s difficulties, which started with Friday’s double-barreled disasters — first an 8.9-magnitude earthquake, then a tsunami. At the Fukushima Daiichi nuclear plant, one containment building housing an overheated reactor had already exploded. A top Japanese official feared the same might soon happen at a second unit. With a government spokesman saying that the units could be in partial meltdown, an alarmed public struggled to understand the safety implications of trace radiation leakage, even as the government said that public safety was not in danger. People here are frightened by what they can’t see and shocked by what they are seeing.

India's nuclear watchdog finds faulty valves in Kudankulam plant South | Reported by Pallava Bagla, Edited by Ashish Mukherjee | Updated: April 20, 2013 10:27 IST New Delhi: For the very first time, India's nuclear watchdog, the Atomic Energy Regulatory Board (AERB), has indicated that faulty parts have been found at the Kudankulam nuclear power plant. The problematic valves are being replaced, said officials.
