States have long worried that their dependence on oil gives producers a means of coercion. The oil market, however, is far larger and more integrated than it used to be. The potential for coercion differs across a series of distinct market segments. In this varied market, the United States remains the dominant force.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR．The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid／small size fossil plants economically．This paper reviews the history and current status of SMR and ASPWR，and also discusses the design concepts, safety features and other advantages thereof.

A universal Fissile Material Cut-off Treaty (FMCT), which would ban the production of fissile material (separated plutonium, highly enriched uranium (HEU), and uranium-233) for nuclear weapons, has long been seen as a key building block in nuclear disarmament and non-proliferation.

Nuclear terrorism is a realistic threat to all countries. First, this article describes the potential threats of nuclear terrorism including nuclear explosives, nuclear sabotage, and dirty bombs. Finally, this article recommends steps to secure nuclear weapons, nuclear materials, and nuclear facilities.
