lil0][ Principle action was to adjust stem travel so that valve met limits. Review of valve l gthistory showed limits adjusted February 7, 1980 which accounted for increased stroket g [ time. Stroke time was not checked after maintenance which resulted in the valve ex-l m lceeding time limits during next scheduled test. Personnel were reinstructed to i

m Iverify stroke time af ter maintenance of T.S. related valves.
