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.

U.S. nuclear capacity factors: Stability and energy dominance
Nuclear generation has inertia. Massive spinning turbines keep electricity flowing during grid disturbances. But nuclear generation also has a kind of inertia that isn’t governed by the laws of motion.
Starting—and then finishing—a power reactor construction project requires significant upfront effort and money, but once built a reactor can run for decades. Capacity factors of U.S. reactors have remained near 90 percent since the turn of the century, but it took more than a decade of improvements to reach that steady state. The payoff for nuclear investments is long-term and reliable.

Beryllium alloys such as Be-Ti and Be-V have been proposed as candidates for advanced neutron multipliers because of their high melting point, high beryllium content, low activation, good chemical stability, etc. In this study, compatibility tests between Be-Ti and structural material were performed, and the effect of Ti content on compatibility was evaluated. Four kinds of Be-Ti alloys (Ti content: 3 to 8.5 at.%) were used in the compatibility tests. After annealing of each Be-Ti alloy in contact with Type 316LN stainless steel (SS316LN), depletion of Be was observed by electron probe microanalysis on the Be-Ti side after annealing at 800°C for 1000 h, but the reaction products were not observed on the Be-Ti side. Reaction products such as BeNi and Be2Fe were observed on the surface of SS316LN. The thickness and growth rate of the reaction layer on the SS316LN side decreased with increasing Ti content in the Be-Ti alloys.
