The Mexican radiation accident (Part II)

A highly respected colleague and friend of mine says he no longer refers to “lessons learned” but, rather, to “lessons recognized” because he has noticed that we don’t always learn our lessons. It’s not too early to recognize some lessons from the Mexican accident of the other week, but the fact that this accident happened […]

Yucca Mountain: Questions and Concerns

Yucca Mountain raises a lot of controversy – let’s face it; if it didn’t then a 4-part series of blog postings would hardly be necessary. Part of the reason for the controversy is that there are a number of worries about the impact of spent fuel disposal on the environment and on the health of […]

Yucca Mountain – Packaging and Storing Radioactive Waste

So – thus far we’ve gone over a little of the history of the Yucca Mountain project and how both geology and hydrogeology can affect waste disposal. What I thought could be interesting today would be to talk a little about how the spent reactor fuel is packaged – both for transport and for disposal […]

Yucca Mountain – hydrogeology

Although I’m a radiation safety professional I studied geology as an undergrad and for my MS (my doctorate is in Environmental Science). This included several classes in hydrogeology – these were some interesting classes, and I added to the experience by doing some work as a field hydrogeologist for a project at a Department of […]

The rocks of Yucca Mountain

As I noted in last week’s posting, nuclear reactors produce high-level radioactive waste during their normal operation. This waste is not voluminous, but it can be dangerous and it needs to be sequestered in an out-of-the-way location for several millennia – in the 70 years since the first nuclear reactor was built there have been […]
