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.

Delivering new nuclear on time, the first time
Mark Rinehart
The nuclear industry is entering a period of renewed urgency, driven by the need for stable baseload power, heightened energy security concerns, and expanded defense infrastructure. Now more than ever, we must deliver new nuclear projects on time and on budget to maintain public trust and industry momentum.
The importance of execution certainty cannot be overstated—public trust, industry investment, and future deployment all hinge on our ability to deliver these projects successfully. However, history has shown that cost overruns and schedule delays have eroded confidence in the industry’s ability to deliver nuclear construction. As we embark on many first-of-a-kind (FOAK) reactor builds, fuel cycle infrastructure projects, and extensive defense-related nuclear projects, we must ensure that execution certainty is no longer an aspiration—it is an expectation.

In this contribution, two ITER loss of plasma control events are investigated. The first one is a failure of pumps and/or pellet injection system which fuel the plasma, producing an overfuelling event. The second examines an increase of external heating during the steady state operation of ITER. For both events, initial simulation parameters are scanned in order to find out which could lead to highest fusion power.Extensive simulation work has been done with AINA-1.0 (July-2007), the safety code developed by Fusion Energy Engineering Laboratory (FEEL-UPC) on the basis of SAFALY. AINA is a hybrid code comprising a zero-dimensional plasma dynamics and radial and poloidal thermal analyses of in-vessel components, and is intended to the quantitative investigation of plasma events in nuclear fusion reactors such as ITER.FEEL-UPC research group has been developing AINA code since 2004. AINA code brings significant improvements in relation to the original SAFALY code, and FEEL-UPC aims to continue improving it in the near future, with new models for plasma wall interactions, blanket thermal analysis, and plasma edge and core.
