W 16 830828 F 93.5 A 3 NA CC INSTRU With the unit at 100% power, scheduled main turbine stop valve testing was being performed. When the last main turbine stop valve opened, an MSIV isolation occurred. A scram followed due to the MSIV's being less than 94%

full open. Spurious actuation of main steam line pressure switches is con-sidered to be the cause of the scram.

One switch was replaced and the switch's operation will be monitored during plant opera t io n . In addition, pulsation dampeners were installed on the sensing lines to the main steam line pressure switches to reduce susceptibility of the switches to pressure oscillations.
