The nuclear industry is highly impacted by national policy. From waste management to R&D funding to energy policy in general, policy decisions shape projects across the whole industry. If you ever wondered how engineers and scientist can help influence this policy, the ANS Congressional Fellowship is a great opportunity to get directly involved. This session will highlight the experiences of panelists who took their technical background and transitioned into policy areas through the ANS Congressional Fellowship. Whether you have questions about what an ANS Congressional Fellow does or about recent policies priorities, this session will provide insights on the relationship between policy and the nuclear industry.
