Title: LLNL Final Design for PDV Measurements of Godiva for Validation of Multi-Physics Simulation

This document is a Final Design (CED-2) Report for IER-268, “PDV Measurements of Godiva for Validation of Multi-Physics Simulation”. These measurements will measure surface velocities in several locations, the initial α and α-t curve as a function of fission yield using existing LLNL assets including: The portable Photonic Doppler Velocimeter (PDV) detector; The “alpha box”, and; Aluminum-encapsulated 235U fission foils. These experiments will be simulated using multi-physics methods funded separately under LLNL-AM2. A supercritical benchmark specification will be developed; and, if funding permits, an ICSBEP (or classified equivalent) evaluation will be published.
