NRC issues draft EA/FONSI for Duane Arnold restart
Efforts by NextEra Energy to restart the Duane Arnold nuclear power plant as early as 2029 continue to move forward with the Nuclear Regulatory Commission's preliminary environmental assessment and determination that the restart would have no significant environmental impacts.
On Thursday, the NRC posted a draft environmental assessment and a finding of no significant impact for the Palo, Iowa, facility; the Federal Register notice was published on Monday. The Department of Energy’s Office of Energy Dominance Financing is a cooperating agency on the draft EA, as the DOE is considering providing financial assistance to the restart project.

Nek5000 is an open-source, highly scalable, high-order, spectral-element-based computational fluid dynamics code. It combines the accuracy of spectral methods with the flexibility of the finite element method. It has been used for a wide range of applications in nuclear energy. It has the capabilities to perform DNS, LES, and unsteady RANS simulations using either an incompressible or low-Mach model. Its high-fidelity capability with the LES model has been well documented with consistent strong performance in international benchmarks. This tutorial will guide users in downloading and compiling Nek5000 as well as setting up and running a simple case.
In order to follow along, attendees should have access to a computer with a Unix based operating system and basic familiarity with using the terminal along with compatible FORTRAN 77 and C compilers installed with a working MPI wrapper. Either ParaView (paraview.org) or VisIt is necessary for visualization of results. We strongly recommend that attendees are familiar with either tool and have one installed prior to the workshop.
