NECX debut: Shaping the next era of energy
The sold-out inaugural Nuclear Energy Conference & Expo (NECX) got off to a bumping start in Atlanta, Ga., Tuesday morning with an opening plenary that felt like part dance party and part highlight reel showing off the latest industry achievements.
That intro left the audience pumped up for Entergy’s CEO and NEI chair Drew Marsh, who welcomed everyone to the event, hosted jointly by the American Nuclear Society and the Nuclear Energy Institute. He spoke to a full house of more than 1,300 attendees, promising a blend of science, technology, policy, and advocacy centered around the future of nuclear energy.

In a reactor of sufficient size and operating at sufficiently high power density, an oscillation in the spatial distribution of power may arise because of interplay between the effect of Xe135 on flux distribution and the fact that its appearance after fission is delayed by the decay time of I135. By use of a very simple reactor model the conditions required to establish such an instability are studied; amplitude and frequency characteristics of the oscillation are also investigated.
