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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

Results of experiments on ICR-heating of hot initial plasma at the end system of AMBAL-M are reported. The heating is performed by an antenna of “Nagoya-III” type installed in the transition region between the mirror and the semicusp. Varying the magnetic field strength in the mirror it was found that the plasma heating in the mirror occurred both at the first and at the second frequency harmonics. The heating does not result in any detectable distortion of the azimuthal symmetry of the initial plasma. The experiments with a small radius of the initial plasma allowed to determine coefficient of diffusion arising in result of RF heating. Measurements of the RF fields spectrum in the plasma demonstrated the emergence of the second frequency harmonic.
At the limiting ICR-heating power it was found that after the pulse of the initial plasma created by the gas-discharge source, the steady-state plasma with duration of 40 ms was sustained in the mirror during RF-power input. The steady state plasma is fed by hydrogen puffing arising in result of considerable recycling. The steady state plasma has the density ∼1012 cm−3, electron temperature ∼40 eV, ion energy 300–400 eV.
