That Carnegie-Mellon report includes Small Modular Nuclear Reactors in its analysis, without being any more hopeful than we are. This is mainly because a new generation of smaller reactors, such as those promised for New Brunswick, will necessarily be more expensive per unit of energy produced, if manufactured individually. The sharply increased price can be partially offset by mass production of prefabricated components; hence the need for selling hundreds or even thousands of these smaller units in order to break even and make a profit. However, the order book is filled with blank pages — there are no customers. This being the case, finding investors is not easy. So entrepreneurs are courting governments to pony up with taxpayers’ money, in the hopes that this second attempt at a Nuclear Renaissance will not be the total debacle that the first one turned out to be.

Chances are very slim however. There are over 150 different designs of “Small Modular Reactors.” None of them have been built, tested, licensed or deployed. At Chalk River, Ontario, a consortium of private multinational corporations, comprised of SNC-Lavalin and two corporate partners, operating under the name “Canadian Nuclear Laboratories” (CNL), is prepared to host six or seven different designs of Small Modular Nuclear Reactors — none of them being identical to the two proposed for New Brunswick – and all of these designs will be in competition with each other. The Project Description of the first Chalk River prototype Small Modular Reactor has already received over 40 responses that are posted on the CNSC web site, and virtually all of them are negative comments.

The chances that any one design will corner enough of the market to become financially viable in the long run is unlikely. So the second Nuclear Renaissance may carry the seeds of its own destruction right from the outset. Unfortunately, governments are not well equipped to do a serious independent investigation of the validity of the intoxicating claims made by the promoters, who of course conveniently overlook the persistent problem of long-lived nuclear waste and of decommissioning the radioactive structures. These wastes pose a huge ecological and human health problem for countless generations to come.

Finally, in the list of projects being investigated, one finds a scaled-down “breeder reactor” fuelled with plutonium and cooled by liquid sodium metal, a material that reacts violently or explodes on contact with air or water. The breeder reactor is an old project abandoned by Jimmy Carter and discredited by the failure of the ill-fated French SuperPhénix because of its extremely dangerous nature. In the event of a nuclear accident, the Tennessee Clinch River Breeder Reactor was judged capable of poisoning twelve American states and the SuperPhénix half of France.

One suspects that our three premiers are only willing to revisit these bygone reactor designs in order to obtain funding from the federal government while avoiding responsibility for their inaction on more sensible strategies for combatting climate changes – cheaper, faster and safer alternatives, based on investments in energy efficiency and renewable sources.
