NEI chief executive highlights “unlimited potential” for nuclear in state of the industry address
Korsnick
In the Nuclear Energy Institute’s annual State of the Nuclear Energy Industry report, NEI president and CEO and Maria Korsnick expressed optimism about the nuclear industry and she issued a call to action.
Her address was part of NEI’s Nuclear Energy Policy forum. The forum, being held in Washington, D.C., on May 20 and May 21, brings together industry leaders, policy stakeholders, and clean energy experts to discuss nuclear advocacy. Korsnick’s remarks focused on the private capital flowing into the industry, progress on regulatory reform and new nuclear technology, and how the U.S. is trying to take the lead on the global nuclear stage.
“We are here at an unprecedented time in our industry history,” Korsnick said. “I’m proud to say that the nuclear industry has a future of unlimited potential.”

An experimental method for the determination of the normalization integral (denominator of perturbation expression) has been developed and used in three fast assemblies. The procedure consists of measuring the apparent reactivity associated with a calibrated 252Cf neutron source at a known power level. The method is independent of the geometrical configuration of the nuclear reactor. Additionally the spatial distributions of the importance of fission neutrons were measured by observing the rate of the linear increase of the neutron population due to the 252Cf source as a function of position in each fast assembly. The measured values of the normalization integrals (N.I.) as well as the measured distribution of were higher than those obtained with multigroup calculations.
