Page • Software for Complex Environments The Arctic Coastal Erosion (ACE) Model provides a field-validated, predictive model of thermal-chemical-mechanical erosion for the Arctic coastline. The ACE Model is created to solve the limitations of current coastal erosion tools. Albany Land Ice is a dynamical core for ice sheet simulations, featuring PDE constrained optimization tools for...

Page • The need to transition from fossil fuels to renewable energy is becoming ever more obvious and urgent. Energy storage is a critical component of the energy transition. Advances in energy storage technology, policy, and applications are quickly increasing around the world, and keeping up with those changes is an ongoing...

Page • “Quantifying radiological risk for mission launch to key decision makers” Launch safety assessment is a fundamental requirement for launching a space vehicle heated, powered, or propelled by a nuclear system. National Security Presidential Memorandum 20 (NSPM-20) establishes safety guidelines and tier levels that form the probabilistic risk baseline used to...

Page • Accident environments can occur during any phase of the launch. Sandia’s ability to identify and mitigate mission risk across the full mission timeline is critical to launch success and helps mission teams focus mitigation efforts on the highest-risk contributors. For the analysis, missions are typically divided into time-based phases that...

Page • Factoring in Launch Weather Conditions Meteorological conditions vary in space and time, which governs the transport and diffusion of the released material. These conditions include wind velocity components, relative humidity, atmospheric turbulence, and pressure. Local meteorology strongly affects both the potential rise of the particles from the fire environments and...

Page • Some blasts and impacts have the potential to breach the multiple layers of protection. Analyses are performed to prove effectiveness and efficacy of the materials and design used when engineering the radioactive power system. For example, the simulation below shows that due to the numerous layers of containment and protection,...

Page • Sandia’s approach and methodology to Space Nuclear Launch Safety is centered around the modeling of detailed simulations, combined with Monte Carlo sequence codes, to create a probabilistic risk analysis. This methodology combination aids in the identification and mitigation of the main sources of risk to create a basis for a successful...
