Zion generating station's two units are Westinghouse four-loop, 1085-MW pressurized water reactors, which went into commercial operation June 19, 1973, and December 24, 1973. Since that time Zion, not unlike many other reactors around this country, has had a significant number of reactor trips. By December of 1984 the Zion units had a total of 74 reactor trips between the two units. During 1987 there were zero reactor trips for both units. In all, unit 1 went 1 yr, 9 months, and 20 days and unit 2, 2 yr and 18 days without a reactor trip. The data for the Zion units show an overall decreasing trend over the years. The purpose of this paper is to provide the reasons for this reduction in trips.
