NPF-73 INSTRUMENTATION TURBINE OVERSPEED PROTECTION LIMITING CONDITION FOR OPERATION 3.3.4 At least one Turbine Overspeed Protection System shall be OPERABLE.
APPLICABILITY:
MODES 1, 2*,
and 3".
ACTION:
l a.
With one throttle valve or one governor valve per high pressure turbine steam line inoperable and/or with one reheat stop valve or one reheat intercept valve per low pressure turbine steam line inoperable, restore the inoperable valve (s) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or i
close at least one valve in the affected steam line(s) or isolate the turbine from the steam supply within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
b.
With the above required Turbine Overspeed Protection System otherwise inoperable, within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> isolate the turbine i
from the steam supply.
c.
The provisions of Specification 3.0.4 are not applicable.
SURVEILLANCE REQUIREMENTS 4.3.4.1 The provisions of Specification 4.0.4 are not applicable.
4.3.4.2 The above required Turbine Overspeed Protection System shall be demonstrated OPERABLE:
I a.
By cycling each of the following valves through at least one complete cycle from the running position:
1)
Four high pressure turbine throttle valves at least i
once per 31 days, 2)
Four high pressure turbine governor valves at least once per 31 days, 3)
Four low pressure turbine reheat stop valves at least i
c once per 18 raonths, 4)
Four low pressure turbine 12 heat intercept valves at least once per 18 months,
- Specification not applicable with all main steam isolation valves and associated bypass valves in the closed position and all other steam flow paths to the turbine isolated.
BEAVER VALLEY - UNIT 2 3/4 3-74 Amendment No. 53
NPF-73 INSTRUMENTATION SURVEILLANCE REQUIREMENTS (Continued) b.
By direct observation of the movement of each of the following valves through one complete cycle from the running position:
1)
Four high pressure turbine throttle valves at least once per 31 days, 2)
Four high pressure turbine governor valves at least once per 31 days, 3)
Four low pressure turbine reheat stop valves at least once per 18 months, 4)
Four low pressure turbine reheat intercept valves at least once per 18 months, l
c.
At least once per 18 months by performing a CHANNEL CALIBRATION'on the turbine overspeed protection systems, i
and
]
d.
At least once per 40 months by disassembling at least one i
of each of the above valves and performing a visual and surface inspection of valve seats,
- disks, and stems and verifying no unacceptable flaws or excessive corrosion. If j
unacceptable flaws or excessive corrosion are found, all other valves of that type shall be inspected unless the nature of the problem can be directly attributed to a-service condition specific to that valve.
For reheat stop and intercept valves the inspection cycle may be increased to a r.aximum of 60 months, provided there is no indication of operational distress.
