The need arose for a small amount of additional fuel to maintain the reactor in operating status from September 1, 1958 until the sched-uled shutdown date.nAll that was necessary was a means of adapting the flat plates to be used as tubular fuel elements. This was accomplished by introducing a cross rolling step in the ALPR rolling schedule, to obtain the necessary core width, and roll forming tubes from these plates. These roll-formed and seam-welded fuel elements were to be placed in the center of the fuel element subassemblies already in the reactor. When this was done, the additional tubes occupied the position normally employed for placement of samples for irradiation.
