August 8 - 9, 2023

The National Nuclear Security Administration (NNSA) Office of Advanced Simulation and Computing (ASC) will hold a Pre-Proposal Meeting for Predictive Science Academic Alliance Program IV (PSAAP IV) on August 8 – 9, 2023. The meeting is for interested U.S., Ph.D.-granting institutions to learn about the next ASC academic program, which is a follow-on to the present ASC PSAAP III (see

The primary goal of PSAAP is to establish validated, large-scale, multi-disciplinary, simulation-based “Predictive Science” as a major academic, applied research program, where predictive science refers to the application of verified and validated computational simulations to predict properties and dynamics of complex systems with quantified uncertainties.

The meeting will start August 8, at 8:30 a.m. and will conclude August 9, at 12:00 p.m. NNSA ASC program managers will present the new scope and requirements of the next ASC Alliance program and articulate the technical areas of interest that will form the basis for the new program. In addition, the meeting will afford academic institutions an opportunity to provide oral comments and feedback on the upcoming Request for Information (RFI). All presentations will be publicly posted on the PSAAP web site (, and attendance is not a prerequisite for responding to the subsequent RFI.
