BASES SURVEILLANCE SR 3.3.17.1 (continued)

REQUIREMENTS A note to the Surveillance excludes the performance of a i

CHANNEL CHECK on Function 4. FPC requested, and was granted, exception from performing a CHANNEL CHECK on this

  • instrumentation as part of Amendment 124, dated October 17, 1989. The basis for not performing this SR is based on the design of the system. The system utilizes differential pressure (dp) measurements across vertical elevations of the hot leg and the reactor vessel when the RCPs are tripped.

Performance of the SR with the RCPs in operation provides no meaningful information, such that a CHANNEL CHECK of this Function is not required.

SR 3.3.17.2 CHANNEL CALIBRATION is a complete check of the instrument channel, including the sensor, to verify the channel responds to the measured parameter (s) within the necessary range and accuracy.

For the Containment Area Radiation instrumentation, a CHANNEL CALIBRATION consists of an electronic calibration of the channel, not including the detector, for range decades above 10 R/hr. The calibration also provides a one point check of the detector below 10 R/hr using a gamma test source (Reference NUREG 0737, Table II.F.1-3).

The 24 month Frequency is based on the results of a review of instrument drift data conducted in accordance with NRC Generic Letter 91-04. The Frequency for the hydrogen monitors is 18 months based on operating experience and was originally selected to be consistent with the typical industry fuel cycle.

A Note clarifies that the neutron detectors are not required to be tested as part of the CHANNEL CALIBRATION.

Adjustment of the detectors is unnecessary because they are passive devices and operating experience has shown them to exhibit minimal drift. Furthermore, there is no adjustment that can be made to the detectors.

1 BASES LC0 23. LPI Pumo Run Status (continued)

LPI Pump Run Status is used by the operator during the ECCS Pump Suction Transfer to initiate the opening of ,

DHV-11 and DHV-12, the " Piggyback" valves.

l LPI Pump Run Status is a Type A variable becaa e the opening of these valves to establish a suction source is a planned manual action and is necessary to maintain HPI in LOCAs where the RCS pressure has not l decreased to the point that LPI will provide injection of coolant into the Reactor Coolant System and when single failures occur which result in only one train of LPI being available.

24. DHV-42 and DHV-43 Open Position DHV-42 and DHV-43 Open Position, the suction valves from the RB sump to the LPI pumps, are used by the operator during the ECCS Pump Suction Transfer to initiate the closing of DHV-34 and DHV-35, the suction valves from the BWST to the LPI pumps.

DHV-42 and DHV-43 Open Position are Type A variables because the closing of DHV-34 and DHV-35 to manually isolate the BWST from the LPI and BS suction is necessary to prevent vortexing and consequential ,

damage to the LPI and BS pumps, which are required for maintaining core and containment cooling.

25. HPI Pumn Run Status HPI Fump Run Status is used by the operator in determining the total HPI flow per pump. If the total flow decreases below the minimum pump flow limits, then a manual action is taken to open the recirculation valves in order to avoid low flow operation which could damage the pump and render it inoperable while it is being used to mitigate a design basis accident.

HPI Pump Run Status is a Type A variable because there are some SBLOCAs that would result in HPI flows of this small a magnitude. Since these actions are necessary to protect equipment that is necessary to mitigate the accident, these are Type A variables.

e LC0 26. RCS Pressure (Low Ranae) l (continued) ,

RCS pressure is measured by pressure transmitters with a span of 0-600 psig. Redundant monitoring capability is provided by two trains of instrumentation. The control room indications-are the primary indications ,

used by the operator during an accident. Therefore, j l the LCO deals specifically with this portion of the instrwnent string.

RCS Pressure (Low Range is classified as a Type B  ;

Category 1 variable beca)use none of the actions taken  !

by the operator based on RCS pressure variables  !

qualifies it as a Type A variable. It is-included ir.

Table 3.3.17-1 as it is a Category 1 variable and relied on by the operators to maintain RCS pressure ,

for several contingency actions included in the E0Ps.

Those actions are: 1) determination that an ES actuation of the LPI pumps should have occurred, 2) selecting Low Temperature Overpressure Protection (LTOP),3 o Heat Remov)al,pening 4) ensureof orop -lines adequate RCPtoNPSH establish at lowDecay RCS pressure, and 5) ensure NDT limits have not been exceeded.

REQUIREMENTS A note to the Surveillance excludes the performance of a CHANNEL CHECK on Function 4. FPC requested, and was granted, exception from performing a CHANNEL CHECK on this instrumentation as part of Amendment 124, dated October 17, 1989. The basis for not performing this SR is based on the design of the system. The system utilizes differential measurements across vertical elevations of the pressure hot leg and(dp)he t reactor vessel when the RCPs are tripped.

Performance of the SR with the RCPs in operation provides no meaningful Function isinformation,d.such not require that a CHANNEL CHECK of this 1 l

CHANNEL CALIBRATION is a complete check of the instrument channel, including the sensor, to verify the channel responds to the measured parameter (s) within the necessary range and accuracy. ,

For the Containment Area Radiation instrumentation, a j CHANNEL CALIBRATION consists of an electronic calibration of the channel, not including the detector, for range decades above 10 R/hr. The calibration also provides a one point check of the detector below 10 R/hr using a gamma test i source (Reference NUREG 0737, Table II.F.1-3). i The 24 month Frequency is based on the results of a review of instrument drift data conducted in accordance with NRC Generic Letter 91-04. The Frequency for the hydrogen monitors is 18 months based on operating experience and was ,

originally selected to be consistent with the typical  !

industry fuel cycle.

A Note clarifies that the neutron detectors are not required to be tested as part of the CHANNEL CALIBRATION.

Adjustment of the detectors is unnecessary because they are passive devices and operating experience has shown them to exhibit minimal drift. Furthermore, there is no adjustment that can be made to the detectors.
