Why Thorium nuclear reactors are just not what they’re cracked up to be

There’s a good reason (or many good reasons) why wind turbines and solar panels are in place all over the world, but there isn’t a single commercial thorium reactor in operation. It’s not because every government in the world is suppressing thorium. It’s most likely because thorium simply isn’t what its proponents say it is.

Why Thorium Nuclear Isn’t Featured on CleanTechnica Update: I have published a new post on this matter (thorium) that includes two rebuttals to the below reposted paper.

I had a reader email me recently asking why we don’t feature thorium nuclear technology on CleanTechnica. To many good-intentioned folks, thorium is an energy panacea that seems perfect. People I respect have asked me the same thing in the past year or so. But thorium is far from perfect. In fact, it’s pretty darn lame, as I think you will see below (if you read this with an open mind).

Now, before I get into the details of why thorium is anything but awesome, I want to say a few things about the culture that surrounds the “thorium will solve all our problems!” idea. Thorium enthusiasts are often willing to make claims like, “if it weren’t for the government, we would have switched to thorium nuclear energy decades ago.” Or, “thorium nuclear will solve all our problems, but it’s been suppressed by big government for decades.”

I have to admit that I’ve gotten into far too many discussions with conspiracy theorists in the past several years (mostly regarding the topic of global warming). Two things I’ve learned are that 1) they think nearly everything wrong in the world is due to governmental conspiracy; 2) you cannot expect to have a logical conversation with them — presenting facts does not matter at all…….

Now, many or most of the commenters and bloggers who are into thorium come into the discussion in a very conspiratorial way, from my experience, which immediately throws up a yellow flag (note: not a red flag, but a yellow one). As I said, I’ve spent way too much time unsuccessfully trying to bring science and logic into discussions with conspiracy theorists……

While hearing a handful of nice things about thorium in what sounds like technical or scientific language might get some people excited, it really shouldn’t. Unless you have a ton of time on your hands to very scientifically study the matter (not read blogs about the topic), you should probably defer to independent experts who have studied the matter, and have carefully studied the claims of the thorium fan club.

You might also consider that some governments (i.e. India) have been trying to get thorium off the ground for decades, with apparently no success, and many others have researched it (including world-leading countries such as Germany, Japan, the UK, Russia, and the US). Do you really think that every government that looks into the matter doesn’t want cheap, safe energy?

Now, that’s all just a preface, but here’s a nice, concise (3-page) rebuttal to the biggest claims regarding thorium (in particular, claims regarding safety, waste, technological advantage, and cost), from the Institute for Energy and Environmental Research and Physicians for Social Responsibility (full repost of the PDF that is linked in the title):
