In a uranium graphite chain reacting pile, the critical size may be considerably reduced by surrounding the pile with a layer of graphite, since such an envelope reflects many neutrons back into the pile. To obtain a 30-year life span, the SSTAR nuclear reactor design calls for a moveable neutron reflector to be placed over the column of fuel. The reflector's slow downward travel over the colu… WebPred 1 hodinou · www.Reflector.com 1150 Sugg Pkwy Greenville, NC 27834 Main Phone: 252-329-9500 Customer Care Phone: 252-329-9505.
