Gary Geernaert, director of DOE's Climate and Environmental Sciences Division, states that «it is critical that federal investments to advance climate science for use by both public and private stakeholders must place significant priority on
incorporating uncertainty quantification methodologies into modeling frameworks.
This environment, designated the Virtual Environment for Reactor Applications (VERA),
incorporates science - based models, state - of - the - art numerical methods, modern computational science and engineering practices, and
uncertainty quantification (UQ) and validation against data from operating pressurized water reactors (PWRs), single - effect experiments, and integral tests.
