Near term actions Cost estimation: removal of components from the PEP-II tunnel. packaging the components into shipping containers (steel shipping boxes) transportation costs to Italy Storage costs in Italy Two to four Italian engineers are coming to SLAC in late February (week of Feb 23) to discuss the task and shipping arrangements. DOE formal review of PEP-II Minimum Maintenance state (MMS) and Disposal and Dispersal (D&D) March 23-24, 2009 at SLAC. Feb 15, 2009 Super-B Orsay Meeting

PEP-II Hardware Conclusions The present Super-B design uses many of the PEP-II components. By weight and numbers, most of the Super-B requests can be fulfilled if the project goes ahead. If other projects do not go ahead, then Super-B could get additional components, primarily injection components. Engineers are studying removal, shipping, planning and costing.
