James Acton argues in Survival that proliferation risks ought to play a bigger role in decisions about nuclear power:

Policymakers, industry insiders and regulators have usually failed to factor proliferation concerns into decisions about nuclear energy. If the policy of abolishing nuclear weapons is to be anything more than rhetoric, proliferation concerns will have to be taken much more seriously and given due weight in decisions about nuclear energy. In some cases, this might involve the decision to forsake a technology that offers and economic advantage where this is outweighed by the proliferation risk. Realistically the gas centrifuge is too economically advantageous, and its use too entrenched, to be phased out. The opportunity does exist, however, to forsake enrichment and other nuclear technologies that have not yet been commercialised.

Today, for instance, Global Laser Enrichment (GLE, owned by General Electric Hitachi) is attempting to commercialise a new enrichment process (known as the SILEX process) based on lasers. GLE expects that the SILEX process will be more profitable to enrichment firms that other technologies. However, the economic benefits of cheaper enrichment to electricity consumers are slight because enrichment typically accounts for less than 5% of the total cost of nuclear electricity. Meanwhile, laser enrichment is probably even more worrying from a prolifieration perspective than the gas centrifuge because detecting a small, clandestine laser-enrichment plant is likely to be even harder than detecting a secret gas-centrifuge enrichment plant of similar capacity. Regulators should factor such concerns into licensing decisions for all nuclear technologies and be willing to deny applications if they determine that the costs outweigh the benefits, as is almost certainly the case with GLE, for instance. Forsaking sensitive nuclear technologies on non-proliferation grounds would be controversial, but justifiable.

I guess we won’t be seeing Tammy Orr, the CEO of GLE, at the next Carnegie Nonproliferation Conference. No word yet on Orr’s taste in shoes.
