The plant shutdwn was requixo1 by Soction 3.0.3 of the Walf Creek 7bchnical Specifications. The SI purps were returned to an operablo condition before a total plant shutdown was attained, with reactor pcwor dropping to a 1cw of 65% during the event and i

full power balng restored at 10:35 pu the sann day.
