Most of the security around nuclear reactors is to prevent disruption of critical power infrastructure and barring access to spent fuel rods. This design would need far less security since it is sealed and not a huge plant that would cut power to half the USA if destroyed. Stealing one of these would be pretty pointless. It would be far easier to get much more dangerous isotopes from one of the thousands of hospitals that use such things or a laboratory. The 20% enrichment is not enough to produce viable weapons either. Uranium enrichment has just gotten way too easy with new centrifuge designs. Applications are mostly stuff like Antarctic research projects and remote oil fields. Also, if it is approved for such uses, it could power a container ship saving huge amounts of money on diesel fuel which is about half their operating cost.
