Earthquake, Tsunami, and Nuclear Power in Japan

August 16, 2011 by Karen Street

Grief was our first reaction when a civilized nation so prepared for earthquakes was devastated. Those of us who live in earthquake country found it hard to tamp down the fear that we can't protect ourselves from nature. Japan, so much better prepared than the West Coast, actually did quite well with the once-in-a-millennium earthquake (the previous largest in that area was M8.3, in 869 CE), but the tsunami killed thousands, left hundreds of thousands homeless, and may have a cost of hundreds of billions of dollars.[read more]

Image via Wikipedia In a Treehugger interview on Climate Change and Intergenerational Justice, NASA’s James Hansen says it is very unfortunate that “a number of nations have indicated that they’re going to phase out nuclear power… The truth is, what we should do is use the more advanced nuclear power. Even the old nuclear power is much...[read more]

Fukushima is Japanese For “It’s Much Worse Than You Thought”

I’m astonished that this interview ran on CNN. I had concluded that nothing short of a China Syndrome event could make the US media mention that still unfolding disaster again. Now that we have an admission from TEPCO that there was a complete meltdown of three cores, and we’re seeing radiation pop up in the US and other places around...[read more]

Buried Pipes Versus Buried Pipelines – Hype Versus Hazard

Several months ago, I signed up to receive press releases from Representative Ed Markey, mainly so you don’t have to endure the pain yourself. On June 21, 2011, I received one titled Markey, Welch to GAO: No Way to Assess Integrity of Buried Pipes at Nuclear Reactors that offers some food for thought about the coordinated effort to...[read more]

The utility has 15 million gallons of radioactive liquid created by efforts to cool its crippled nuclear reactors TEPCO is a bearer of a water problem that sets daunting challenges ahead of its ambitious plan to decommission the Fukushima reactor site. In many ways, getting the millions of gallons of radioactive water out of buildings...[read more]

TEPCO has detected radiation of up to 4,000 millisieverts per hour in the air at the building housing reactor unit 1 at the Fukushima nuclear facility. Readings were collected from a robot sent into reactor unit 1 on June 3rd. Heavy steam has also been observed rising from the floor of reactor unit 1.Record Radiation Levels at...[read more]

Modeling Meltdowns In Reactors And The Media

May 27, 2011 by Dan Yurman

Computer predictions of failure at Fukushima World Nuclear News has a report that computer analysis of reactor damage at Fukushima has indicated more serious fuel melting has probably occurred than previously thought at units 2 and 3. Two simulations show the water levels in the reactor pressure vessels far below where battered...[read more]

In a recent ANS Nuclear Cafe post, I mentioned the radiation hormeis theory proposed more than three decades ago by Dr. Don Luckey, a biochemist and nutritionist who wrote a book in 1980 titled Hormesis With Ionizing Radiation. According to Dr. Luckey and a number of other researchers in the field, a small dose of radiation can provide...[read more]
