As you are aware, the panel concluded the changes to the models appear generally sound and that the proposed implementation appears reasonable. However, the panel determined they could not assess implementation of the three models and their interactions with other conceptual models without a total system performance assessment (PA). They recommended that the changed models be re-reviewed in the context of the total system PA and concluded that the status of the models would remain "conditionally adequate" until the final review is completed.
