Reminds me of what they used to say about nuclear power plants. The Titanic slipped into the sea on May 31, 1911.

These guys must be getting money from somewhere to be pushing this: Legislation designed to facilitate development of small, scalable reactors was introduced in the U.S. House of Representatives this week.

In my experience, there is absolutely no way to know what is going on at a nuclear power plant without basically living there, and for a long time, probably permanently. These facilities are a complicated mix of people and technology that can’t be adequately assessed via inspections. Having people in residence is the only feasible […]

At the No. 1 reactor at Fukushima, they are having trouble keeping water on top of things because it’s leaking out the bottom where, as one utility manager put it according to Reuters: “The fuel pellets likely melted and fell, and in the process may have damaged … the pressure vessel itself and created a […]

Modelers can be really smart, and their models can be really sophisticated. But there’s a danger that they, or those in positions of authority, actually believe the models. Recall that modeling low-probability events is fraught with difficulty. And they may be missing some simple, cost-effective solutions by over-relying on computer-generated scenarios. A recent article points […]

From the wikipedia article on the recent movie: Into Eternity is a feature documentary film directed by Michael Madsen, released in 2010.  It follows the digging and pre-implementation of the Onkalo nuclear waste repository on the island of Olkiluoto, Finland. Director Michael Madsen questions Onkalo’s intended eternal existence, addressing an audience in the remote future. […]

The NYTimes has an article getting into radiation fears and how they are “overblown,” but unfortunately the author does not use the term “radioisotopes,” and does not distinguish between radiation we receive from x-ray machines and the like, and radiation we can receive from ingestion of radioisotopes. As an example, the article states that at […]

Much has been written about the Yucca Mountain nuclear repository, which most are saying is dead in the water because funding for it has ended. Congress has been grilling NRC Chairman Jaczko about what some are calling foot-dragging over the Yucca Mountain decision, and, from what I gather, whether delays in a final NRC vote […]

WSJ reports Regulations currently require nuclear power plants to have as few as four hours of emergency power. NRC Chairman Gregory Jaczko said during a commission meeting that this might not be enough, That’s pretty outrageous, even without the events in Japan. The larger question is, what else is there that this bare-bones standby power […]
