NRC approves TerraPower construction permit
Today, the Nuclear Regulatory Commission announced that it has approved TerraPower’s construction permit application for Kemmerer Unit 1, the company’s first deployment of Natrium, its flagship sodium fast reactor.
This approval is a significant milestone on three fronts. For TerraPower, it represents another step forward in demonstrating its technology. For the Department of Energy, it reflects progress (despite delays) for the Advanced Reactor Demonstration Program (ARDP). For the NRC, it is the first approval granted to a commercial reactor in nearly a decade—and the first approval of a commercial non–light water reactor in more than 40 years.
Educational Session|Panel|Sponsored by Plant Reliability
Monday, August 5, 2024|3:30–5:00PM EDT|Banyan 2
The increasing trend in extreme weather events disrupting the electric grid has resulted in environmental resiliency becoming a focal point for energy providers and regulatory agencies. To this effect, INPO recently release a principles document, INPO 24-003 (Resiliency – Strengthening Defenses Against External Forces) and a Tier 2 guidance document specifically associated with assessing climate vulnerabilities, INPO 24-002 (Climate Vulnerability Assessment).
This session will provide perspective on these INPO documents and discuss next steps for utilities to ensure environmental resiliency. The session will also address a specific challenge one utility is facing due to the changes in the local environment, which is directly affecting the supply of cooling water to the station. Finally, the session will discuss challenges in the management of the seasonal readiness process and potential impacts on plant reliability.
