ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

JET has made a strong contribution to the understanding of stability issues for the tokamak. An overview of its main achievements is presented, with emphasis on the latest progress in resolving the key issues for ITER. In particular, we conclude that control or avoidance strategies for neoclassical tearing modes (NTMs) will be necessary for good performance in ITER. JET studies have provided insights into the transport effects, seeding, underlying physics, and threshold scaling of NTMs. A range of mechanisms are found that can trigger performance-impacting NTMs with various mode numbers. Experiments have highlighted the key role of the sawtooth in triggering the NTM and have developed sawtooth control. The underlying physics suggests increased likelihood of NTM triggering as ITER scales are approached. Extensions have also been made in understanding of error field locked modes and resistive wall modes (RWMs). The predictions for ITER of error field locked mode thresholds have been developed and refined taking account of JET data. Direct inference from experimental studies and benchmarking of magnetohydrodynamic codes have both contributed to improved understanding of RWM stability in ITER. From these developments, and from the parameter space it accesses, JET continues to provide an essential role, and unique operating points, to further test and resolve the stability issues of tokamak physics.
