Probabilistic estimates of the cost and performance of future nuclear energy systems under different scenarios of government research, development, and demonstration (RD&D) spending were obtained from 30 U.S. and 30 European nuclear technology experts. The majority expected that such RD&D would have only a modest effect on cost, but would improve performance in other areas, such as safety, waste management, and uranium resource utilization. The U.S. and E.U. experts were in relative agreement regarding how government RD&D funds should be allocated, placing particular focus on very high temperature reactors, sodium-cooled fast reactors, fuels and materials, and fuel cycle technologies.

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.

"Regime sustainability despite different internal crises and foreign threats underlines the fact that Iran enjoys a relatively rational decision-making process. The central slogan of the Iranian Revolution was "Independence, Freedom, and Islamic Republic." Today, Iran is an independent state, as it does not belong to an Eastern or a Western bloc. Although the country has not realized its ambition of economic independence, the revolution has provided economic welfare. Rural development has improved people's lives by providing villages with water, electricity, and infrastructure. The essence of independence also
referred to the specific relations between the Iranian monarchy and the United States. The US-sponsored 1953 coup against the popular Muhammad Mosaddeq government made Iran an American client state, leading to Iranian dependence in all aspects."

"Revolutions either expand to export their ideologies or preserve themselves from the outside world. The 1979 Islamic revolution of Iran is no exception. A careful reading of Iran's actions in the region shows how and why Iran has shifted its policies to meet the latter aim. Since the revolution, Iran's leaders have faced the challenge of balancing their ideological (idealism) and geopolitical (pragmatism) approaches to foreign policy. Gradually, the Iranian leadership has come to focus on the geopolitical factor in the conduct of foreign policy; today, ideology one factor among many other sources of Iran's power, and serves the aim of preserving Iran's national security and interests...."
