Nuclear Issues

Safety has always been an important criterion for designing nuclear reactors, but in addition to safety, there are at least four other values that play a key role, namely, security (i.e., sabotage and proliferation), sustainability (i.e., environmental impacts, energy resource availability), economic viability (i.e., embarking on new technology and its continuation), as well as intergenerational justice (i.e., what we leave behind for future generations). This chapter reviews the evolution of generations of nuclear reactors (I, II, III, III, and IV) in terms of these values.

Many Chinese worry that as Japanese politics moves rightward, it could result in the country seeking its own weapons. Beijing's concerns have intensified with its confrontation with the Abe administration over historical recognition and territorial issues. In this op-ed, Hui Zhang argues that it is time for Tokyo to stop reprocessing and eliminate its surplus plutonium as soon as possible. Tokyo should address concerns over its reprocessing plans and plutonium stocks. To reduce suspicions, Tokyo should take specific steps to abide strictly by its "no surplus plutonium policy".

Each year, the Science, Technology, and Public Policy (STPP) Program at the Belfer Center for Science and International Affairs at the Harvard Kennedy School welcomes new pre- and post-doctoral fellows and visiting researchers to a select team of scholars exploring the critical role that science and technology play in everyday life.

Despite substantial progress in improving nuclear security in recent years, there is more to be done.  The threats of nuclear theft and terrorism remain very real.  This paper recommends learning from the much stronger national and international efforts in nuclear safety, and in particular taking steps to build international understanding of the threat; establish effective performance objectives; assure performance; train and certify needed personnel; build security culture and exchange best practices; reduce the number of sites that need to be protected; and strengthen the international framework and continue the dialogue once leaders are no longer meeting regularly at the summit level.

Through structured interviews and a literature review, we assess which approaches to protection against insider thefts in the casino and pharmaceutical industries could be usefully applied to strengthen protections against insider theft in the nuclear industry, where insider thefts could have very high consequences.

"The military buildup by China, its Asia-Pacific neighbors and the United States is creating a classical security dilemma that is increasing the potential for military conflict in the region. Although history is replete with conflicts between existing and rising powers, conflict between China and the United States is not preordained. Opportunities exist in both the diplomatic and military arenas for both countries to actively engage the other in open and direct communication to increase transparency, reduce tensions, and improve understanding. It is in the best interest of the United States, China and countries around the world to confront the reality that is a rising nuclear-armed China and, in doing so, manage its accession into the regional and world order without conflict."

Before the Fukushima Daiichi nuclear accident, China had big nuclear expansion plans, with more than 40 reactor units under construction or in planning. The Fukushima disaster led China to conduct safety inspections of all its reactors and to suspend nuclear project approvals until a new nuclear safety plan could be adopted. Under Beijing's new safety regulatory system, reactors that are operating or under construction will be spared major redesign, but future projects will face re-engineering, perhaps leading the Chinese to adopt safer third-generation reactor designs created by Chinese firms.

"The conventional wisdom among those who looked at the Middle East used to be that you had a choice either of supporting the autocrat or being stuck with the religious extremists. The extraordinary diffusion of information created in Egypt and other Middle Eastern countries reveals a strong middle that we weren't fully aware of. What is more, new technologies allow this new middle to coordinate in ways unseen before Twitter, Facebook, and so forth, and this could lead to a very different politics of the Middle East. This introduces a new complexity to our government's dealings with the region."

"The focus of the workshop was on the demonstration stage of the technology innovation cycle. Current policies do not adequately address the private sector’s inability to overcome the demonstration "valley of death" for new energy technologies. Investors and financiers fear that the technology and operational risks at this stage of the cycle remain too high to justify the level of investment to build a commercial-sized facility."

"There is broad political consensus that the current energy system in the United States is unable to meet the nation's future energy needs, from the security, environment, and economic perspectives. New energy technologies are required to increase the availability of domestic energy supplies, to reduce the negative environmental impacts of our energy system, to improve the reliability of current energy infrastructure (e.g., smart grid, energy storage), and to increase energy efficiency throughout the economy."
