WIPP: Lessons in transportation safety
As part of a future consent-based approach by the federal government to site new deep geologic repositories for nuclear waste, local communities and states that are considering hosting such facilities are sure to have many questions. Currently, the Waste Isolation Pilot Plant in New Mexico is the only example of such a repository in operation, and it offers the opportunity for state and local officials to visit and judge for themselves the risks and benefits of hosting a similar facility. But its history can also provide lessons for these officials, particularly the political process leading up to the opening of WIPP, the safety of WIPP operations and transportation of waste from generator facilities to the site, and the economic impacts the project has had on the local area of Carlsbad, as well as the rest of the state of New Mexico.

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 workshop will guide users in downloading and compiling Nek5000 as well as setting up and running a few demonstration cases.
To participate, attendees must 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. For details see here: https://nek5000.github.io/NekDoc/quickstart.html. Either ParaView (www.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.
Cost: $99
