Daily Run Plan

Here are details of the daily run plan. See also the global Run Plan. The person responsible should ensure that a crew of experts is available for the shift. This schedule will be updated frequently by the Run Coordinator as the situation on the ground changes.

Daily Run Plan for PREX   (latest at bottom)
Date (2010) Shift ---------- Activity (Responsible) ---------- --- Status ---
