Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

A digital readout-type period meter has been used to monitor period information during critical mass experiments. Its range of measurement extends from to 1000 sec. It can be used to measure the slope of any linearly changing signal. By using a logarithmic amplifier in conjunction with the meter, it will measure an exponential slope. The instrument provides a greater readout range and is less susceptible to noise than the conventional differentiating operational amplifier types presently used at the Rocky Flats Plant Nuclear Safety Facility. Noise frequency periods are much shorter than the periods measured during an experiment. Typically, the experiment periods are on the order of 1 min and greater. The input stage of the instrument has a cutoff frequency allowing these typical periods to be measured, but above the cutoff frequency response decreases at 20 db per decade. Contrary to this, the conventional differentiating operational amplifier-type period meter increases in response above its cutoff frequency. The error in period readings was found to be less than 5% probable error.
