a.
At least once per 31 days in HODES 1 and 2 when the main turbine is operating by cycling each of the following valves through at least one complete cycle from the running position:
1)
Four high pressure turbine stop valves, 2)
Four high pressure turbine governor valves, 3)
Six low pressure turbine reheat stop valves, and 4)
.Six low pressure turbine reheat-intercept valves.
b.
At-least'once par 31 days in MODES 1 and 2 when the main turbine is
- operating by direct observation of the movement of each of the above
. valves through one complete cycle from the running position, c.
