Atomically Speaking, the Nuclear Energy and National Security Coalition's Official Podcast

ATOMICALLY SPEAKING | Regulating at Scale & Speed: A Conversation with Ho Nieh, Chairman of the Nuclear Regulatory Commission

In this episode, NENSC Co-Chair Daniel Poneman sits down with Ho Nieh — Chairman of the U.S. Nuclear Regulatory Commission — at a defining moment for the agency and for American nuclear energy. The conversation explores how the NRC is implementing the ADVANCE Act and EO 14300, what a more risk-informed regulatory framework means in practice, and why getting this right will determine whether nuclear can be deployed at scale across America.

Two Sides of the Coin: A Conversation with Jay Tilden and Chris Ploch, NENSC’s New Leadership Team

In this episode, NENSC Co-Chair Daniel Poneman sits down with Jay Tilden and Chris Ploch — the Coalition's newly appointed Executive Director and Deputy Director — to explore how DOE's twin missions of national nuclear security and civilian energy must work in concert, why a domestic uranium enrichment capability is both a security and economic imperative, and what listeners can expect from NENSC in the months ahead.

Powering the Comeback: A Conversation with Bryan Hanson, Senior Executive Vice President and Chief Generation Officer at Constellation

In this episode of Atomically Speaking, NENSC Co-Chair, Daniel Poneman sits down with Bryan Hanson to explore the resurgence of nuclear energy in the United States. From restarting Three Mile Island as the Chris Crane Clean Energy Center to extending reactor lifespans and meeting surging demand from AI and electrification, Mr. Hanson shares an inside look at how the nation’s largest nuclear fleet is navigating a rapidly evolving energy landscape and why nuclear power remains critical to both economic growth and national security.

Fueling the Future: A Conversation with Brad Williams, Senior Policy Advisor at the Idaho National Laboratory

In this episode of Atomically Speaking, NENSC Co-Chair Daniel Poneman sits down with Brad Williams, Senior Policy Advisor at the Idaho National Laboratory to explore the evolving landscape of nuclear energy in the United States. From rebuilding the nuclear fuel supply chain to advancing bipartisan legislation, they discuss how policy, innovation, and collaboration are shaping a new era of nuclear deployment both at home and globally.

A Conversation with Dr. Stephen Streiffer, Director of the Oak Ridge National Laboratory

In this episode of Atomically Speaking, NENSC Co-Chair Daniel Poneman sits down with Dr. Stephen Streiffer to discuss the legacy of the Manhattan Project and how it continues to shape the Oak Ridge National Laboratory’s mission today. Dr. Streiffer walks through the history of uranium enrichment and the technologies used over the years, from the gaseous diffusion process and electromagnetic separation to laser isotope separation technologies now being studied for potential commercial energy applications. He also discusses Oak Ridge National Laboratory’s current priorities and the role it plays in supporting the May 2025 White House Executive Orders aimed at restoring U.S. nuclear leadership, including the DOE Genesis Mission — a national initiative to accelerate scientific discovery through the use of artificial intelligence.
