load shifting of Nuclear Power plants using cryogenic energy storage technology
Applied Energy, 2014Co-Authors: Yongliang Li, Dacheng Li, Shuhao Wang, Yulong Ding, Xiang WangAbstract:To balance the demand and supply at off-peak hours, Nuclear Power plants often have to be down-regulated particularly when the installations exceed the base load requirements. Part-load operations not only increase the electricity cost but also impose a detrimental effect on the safety and life-time of the Nuclear Power plants. We propose a novel solution by integrating Nuclear Power generation with cryogenic energy storage (CES) technology to achieve an effective time shift of the electrical Power output. CES stores excess electricity in the form of cryogen (liquid air/nitrogen) through an air liquefaction process at off-peak hours and recover the stored Power by expanding the cryogen at peak hours. The combination of Nuclear Power generation and the CES technologies provides an efficient way to use thermal energy of Nuclear Power plants in the Power extraction process, delivering around three times the rated electrical Power of the Nuclear Power plant at peak hours, thus effectively shaving the peak. Simulations are carried out on the proposed process, which show that the round trip efficiency of the CES is higher than 70% due to the elevated topping temperature in the superheating process and thermal efficiency is also substantially increased.

reassessing the safety of Nuclear Power
Energy research and social science, 2016Co-Authors: Spencer Wheatley, Benjamin K Sovacool, Didier SornetteAbstract:We summarize the results of a recent statistical analysis of 216 Nuclear energy accidents and incidents (events). The dataset is twice as large as the previous best available. We employ cost in US dollars as a severity measure to facilitate the comparison of different types and sizes of events, a method more complete and consistent that the industry-standard approach. Despite significant reforms following past disasters, we estimate that, with 388 reactors in operation, there is a 50% chance that a Fukushima event (or more costly) occurs every 60–150 years. We also find that the average cost of events per year is around the cost of the construction of a new plant. This dire outlook necessitates post-Fukushima reforms that will truly minimize extreme Nuclear Power risks. Nuclear Power accidents are decreasing in frequency, but increasing in severity.

the national politics of Nuclear Power economics security and governance
2012Co-Authors: Benjamin K Sovacool, Scott Victor ValentineAbstract:This book offers a comprehensive assessment of the dynamics driving, and constraining, Nuclear Power development in Asia, Europe and North America, providing detailed comparative analysis. The book formulates a theory of Nuclear socio-political economy which highlights six factors necessary for embarking on Nuclear Power programs: (1) national security and secrecy, (2) technocratic ideology, (3) economic interventionism, (4) a centrally coordinated energy stakeholder network, (5) subordination of opposition to political authority, and (6) social peripheralization. The book validates this theory by confirming the presence of these six drivers during the initial Nuclear Power developmental periods in eight countries: the United States, France, Japan, Russia (the former Soviet Union), South Korea, Canada, China, and India. The authors then apply this framework as a predictive tool to evaluate contemporary Nuclear Power trends. They discuss what this theory means for developed and developing countries which exhibit the potential for Nuclear development on a major scale, and examine how the new "renaissance" of Nuclear Power may affect the promotion of renewable energy, global energy security, and development policy as a whole. The volume also assesses the influence of climate change and the recent Nuclear accident in Fukushima, Japan, on the Nuclear Power industry’s trajectory. This book will be of interest to students of energy policy and security, Nuclear proliferation, international security, global governance and IR in general.

the socio political economy of Nuclear Power development in japan and south korea
Energy Policy, 2010Co-Authors: Scott Victor Valentine, Benjamin K SovacoolAbstract:This paper analyzes the socio-cultural, political and economic conditions prevalent during the inception of Nuclear Power programs in Japan and South Korea in order to identify commonalities which support Nuclear Power program expansion. The study identifies six factors as having a clear influence on supporting Nuclear Power development: (1) strong state involvement in guiding economic development; (2) centralization of national energy policymaking and planning; (3) campaigns to link technological progress with national revitalization; (4) influence of technocratic ideology on policy decisions; (5) subordination of challenges to political authority, and (6) low levels of civic activism. The paper postulates that insights from this study can be used to assess the propensity of nations which have the emergent capacity to support Nuclear Power development to actually embark on such programs.
