Nuclear Bearings

Nuclear bearings are used in the linear actuation system which position the control rods into the fuel bundle. In an emergency situation, the control rods are dropped into the fuel bundle to absorb the reactor heat, which dictates that the bearings must not, under any circumstances, fail. Such bearings are manufactured and controlled under the strict aerospace procedures which Barden employs, providing full traceability, controlled lubrication processes and complete retention of records.
