'Rod Run-In Blade 'D' Not In Contact With Magnet On February 8, a "Rod Not In Contact With Magnet Rod Run-In" was automatically initiated when control blade "ID" anvil separated from its'ma-ne~t during a routine outward shimming evolution. The reactor was shutdown and th'epull rod to housing alignment wa's checked and verified, and the anvil and magnet were cleaned The control rod was satisfactorily withdrawn to
.--- the-full out position-as part-of the retest -The reactor was refueled and subsequently returned to 10 MW operation.
