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
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

We welcome ANS members who have careered in the community to submit their own Nuclear Legacy stories, so that the personal history of nuclear power can be captured. For information on submitting your stories, contact nucnews@ans.org.
As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

Scenarios of the evolution of the French nuclear fleet are developed by CEA, EDF, ORANO and FRAMATOME, following conservative assumptions in terms of technology, safety, regulation and costs. In the next decades, the SFR demonstrator ASTRID paves the way to the deployment of a few fast reactors used to consume PWR MOX spent fuel in priority. In the 2090 to 2120 period, the number of SFR goes on growing. The fleet eventually comes to a mix of breeder SFR and EPR (European Pressurized water Reactor) supplied with LEU and MOX fuels. Such a fleet composition enables the stabilization of spent fuel and plutonium inventories. Previously, a steady-state regime was reached in the next century, thanks to a fleet composed of ~40% SFR.
A new methodology has been applied. This methodology was recently developed to put into equations the equilibrium conditions of nuclear power systems composed of various reactor types. Fleets with the less SFR are now favored, since SFR are reputed to be more expensive than thermal reactors. Results show that the fraction of SFR in the fleet can be reduced of around 10% in comparison to the fleet previously deployed. However, the fleet composition which minimizes the SFR fraction at equilibrium leads to plutonium contents in EPR MOX fuels near the safety limit which is currently accounted for.
