This report described plant operational management during the 7th annual inspection of Experimental Fast Reactor JOYO from September 1988 to January 1989. One of the important purposes of this inspection is to find a rationality inspection method for LMFBR plants. Therefore, almost inspection items with various modifications and preparation for irradiation were completed for about 3.5 months. This is the shortest record on JOYO. The inspection schedule was very tight and complicated, but it was successfully finished in cooperation with members of operation and maintenance section, by adequate operational management and advanced preparation for inspection. Useful operational management techniques for rationality inspection were obtained, through the experience of 7th annual inspection.
