ABSTRACT
Multiple factors are acting as constraints on the expansion of the use of nuclear energy worldwide. The strength and mix of factors varies from country to country, making it often impossible to generalize globally. Many of the factors are matters of contention and controversy, most obviously the question of the economic feasibility of new nuclear build and the challenges of nuclear waste disposition. The fact that these issues generate controversy creates uncertainty for governments, industry and private financiers considering investing in nuclear energy. This uncertainty itself acts as a brake on a nuclear energy revival.
