Findings of the ANS Executive Order Expert Advisory Group
On May 23, President Donald Trump signed four Executive Orders (EOs) designed to “usher in a nuclear energy renaissance” by building on federal policies and programs and directing efficiencies in the licensing, siting, development, and deployment of advanced reactor technologies.
In order to evaluate the specific proposals contained in the EOs, a group of experts was convened from various sectors of the U.S. nuclear technology enterprise, under the auspices of the ANS External Affairs Committee, to compare the EOs against existing ANS board-approved Position Statements and to offer constructive input for subsequent implementation by the Trump administration.
The group’s findings and feedback, which were delivered by ANS CEO Craig Piercy to ANS President Lisa Marshall and the Board of Directors, are listed below, grouped by individual EO.

All nuclear plant instrumentation connected at installation points to low-voltage power circuits will be exposed to electric fast transients induced by power switching and lightning. Unwarranted interruption of instrumentation due to transients may result in serious loss through bothersome activation of a plant's engineering safeguards. In this study, in situ responses of a digital wide-range neutron monitor is studied in terms of real-time disturbances during electric transients. Using correlation analysis, a systematic methodology between transient responses and steady-state electromagnetic emission spectra has been developed and justified to be useful for transient isolation. Moreover, results of various on-site approaches to improve the electromagnetic compatibility of safety-related instrumentation are discussed.
