There is currently sparse literature on how to implement systematic and
comprehensive processes for modern V&V/UQ (VU) within large computa-
tional simulation projects. Important design requirements have been identi ed
in order to construct a viable “system” of processes. Signi cant processes that
are needed include discovery, accumulation, and assessment. A preliminary
design is presented for a VU Discovery process that accounts for an important
subset of the requirements. The design uses a hierarchical approach to set
context and a series of place-holders that identify the evidence and artifacts
that need to be created in order to tell the VU story and to perform assess-
ments. The hierarchy incorporates VU elements from a Predictive Capability
Maturity Model and uses questionnaires to de ne critical issues in VU. The
place-holders organize VU data within a central repository that serves as the
ocial VU record of the project. A review process ensures that those who will
contribute to the record have agreed to provide the evidence identi ed by the
Discovery process. VU expertise is an essential part of this process and ensures
that the roadmap provided by the Discovery process is adequate.
Both the requirements and the design were developed to support the Nuclear
Energy Advanced Modeling and Simulation Waste project, which is develop-
ing a set of advanced codes for simulating the performance of nuclear waste
storage sites. The Waste project served as an example to keep the design of
the VU Discovery process grounded in practicalities. However, the system is
represented abstractly so that it can be applied to other M&S projects.
