The valve is automatically supposed to close down only by 3 to verify operability each 92 days, however, it traveled past this point and closed completely. High steam flow resulted in remaining 2 lines with accompaning low pressure causing safety injection & reactor trip. The 3 MSTV's were inspected and their 30 limit reset. The test is now no longer required to be performed while at power.

80-13 (G) 4-8-80 Time: 1147.. turbine' trip / reactor trip. Operator in turbine  ;

building was investigating the cause of a High level alarm in the.EHC 1 reservoir. The actual level was normal. He attempted to cycle the alarm switch to see if it was sticking but he was on the Lo-Lo alarm switch. Upon Lo-Lo alarm both EHC pumps tripped lock-out causing low EHC pressure signal to trip the turbine.
