Nuclear Issues

The Advanced Small Pressurized Water Reactor (ASPWR) can be used in remote power grids and replaces mid/small size fossil-fuel plants economically. Current ASPWR deeply adopts modular and integrated pressure vessel design—and a passive safety system—which effectively improves plant safety and economy. This paper performs the comparative study of safety and economy features in ASPWR and large PWRs. The authors suggest that China should start R&D programs in ASPWR.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.

This article examines and evaluates security measures at Chinese civilian nuclear power plants and suggests ways to improve them. It also reviews current export control policies and systems, identifies likely challenges to the expanding nuclear sector, and proposes possible solutions.

Matthew Fuhrmann's article "Spreading Temptation: Proliferation and Peaceful Nuclear Cooperation Agreements," was published by in the Summer 2009 issue of International Security. In his article, Dr. Fuhrmann argues "Peaceful nuclear cooperation—the transfer of nuclear technology, materials, or know-how from one state to another for peaceful purposes—leads to the spread of nuclear weapons. With a renaissance in nuclear power on the horizon, major suppliers, including the United States, should reconsider their willingness to assist other countries in developing peaceful nuclear programs."

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."

Hui Zhang re-examines the North Korean explosion on October 9, 2006. His research suggests that the test was likely not a failure if Pyongyang had planned for a yield of 4 kt, as it told Beijing prior to the event.

Matthew Bunn argues that plutonium disposition—physically transforming it into a form that would be difficult and costly to recover for use in nuclear weapons—if carried out on a large scale would “mark a key step toward deeper and less-reversible nuclear arms reductions.”  But, as he documents, delays, costs, and obstacles have plagued plutonium disposition plans in both the United States and Russia.

Hui Zhang provides a path-breaking technical assessment of the Korean nuclear test, publishing a comment (with co-authors Jungmin Kang and Frank von Hippel) on the test and the limits of nuclear forensics in Arms Control Today.
