Pressurizer Water Level-Hiah (continued)
SAFETY ANALYSES, LCO, and fourth channel is not required to address control / protection interaction concerns.
The level channels do not actuate the safety valves, and the high pressure reactor trip is set below the safety valve setting. Therefore, with the slow rate of charging available, pressure overshoot due to level channel failure cannot cause the valve to lift before reactor high pressure trip.
In MODE 1, when there is a potential for overfilling the pressurizer, the Pressurizer Water Level-High trip must be OPERABLE. This trip Function is automatically enabled on increasing power by the P-7 interlock. On decreasing power, this trip Function is automatically blocked below P-7.
Below the P-7 setpoint, transients that could raise the pressurizer water level will be slow and the operator will have sufficient time to evaluate unit conditions and take corrective actions.

Reactor Coolant Flow-Low a.
Reactor Coolant Flow-low (Sinole Loool The Reactor Coolant Flow-Low (Single Loop) trip Function ensures that protection is provided against violating the DNBR limit due to low flow in on.e or more RCS loops, while avoiding reactor trips due to normal variations in loop flow.
Above the P-8 setpoint, which is approximately 48% RTP, a loss of flow in any RCS loop will actuate a reactor trip.
The setpoints are based on a minimum measured flow of 95,500 gpm (Unit 1) 96,250 gpm (Unit 2). Each RCS loop has three flow detectors to monitor flow.
The flow signals are not used for any control system input.
The LC0 requires three Reactor Coolant Flow-Low channels per loop to be OPERABLE in MODE 1 above P-8.
In MODE 1 above the P-8 setpoint, a loss of flow in one RCS loop could result in DNB conditions in the core.
In MODE 1 below the P-8 setpoint, a (continued)

Reactor Coolant Flow-Low (Two Lc 35.),
The Reactor Coolant Flow-Low (Two Loops) trip Function ensures that protection is provided against violating the DNBR limit due to low flow in two or more RCS loops while avoiding reactor trips due to normal variations in loop flow.
Above the P-7 setpoint and below the P-8 setpoint, a loss of flow in two or more loops will initiate a reactor trip. The setpoints are based on a minimum measured flow of 95,500 gpm l
(Unit 1) 96,250 gpm (Unit 2). Each loop has three flow detectors to monitor flow.- The flow signals are not used for any control system input.
The LC0 requires three Reactor Coolant Flow-Low channels per loop to be OPERABLE.
In MODE I above the P-7 setpoint and below the P-8 setpoint, the Reactor Coolant Flow-Low (Two Loops) trip must be OPERABLE. Below the P-7 setpoint, all reactor trips on low flow are automatically blocked since power distributions that would cause a DNB concern at this low power level are unlikely. Above the P-7 setpoint, the reactor trip on low flow in two or more RCS loops is automatically enabled. Above the P-8 setpoint, a loss of flow in any one loop will actuate a reactor trip because of the higher power level and the reduced margin to the design limit DNBR.

I RCSP/TLimits B 3.4.3' BASES ACTIONS-L1 and C.2 (continued)
Condition C is modified by a Note requiring Required Action C.2 to be completed whenever the Condition is entered. The Note emphasizes the need to perform the evaluation of the effects of the excursion outside the i
allowable limits.
Restoration alone per Required Action C.1 is insufficient because higher than analyzed stresses may have occurred and may have affected the RCPB integrity.
SURVEILLANCE SR 3.4.3.1 REQUIREMENTS Verification that operation is within the specified limits is required every 30 minutes when RCS pressure and temperature conditions are undergoing planned changes. This Frequency is considered reason 0ble in view of the control room indication available to monitor RCS status. Also, since temperature rate of change limits are specified in hourly increments, 30 minutes permits assessment and correction for minor deviations within a reasonable time.
Surveillance for heatup, cooldown, or ISLH testing may be discontinued when the definition given in the relevant plant procedure for ending the activity is satisfied.
This SR is modified by a Note that only requires this SR to be performed during system heatup, cooldown, and ISLH testing. No SR is given for criticality operations because LCO 3.4.2 contains a more restrictive requirement.

This Specification is to ensure that Surveillance are performed to verify the OPERABILITY of systems and components, and that variables are within specified limits.

Surveillance do not have to be performed when the unit is in a MODE or other specified condition for which the requirements of the associated LC0 are not applicable, unless otherwise specified. The SRs associated with a test exception are only applicable when the test exception is used as an allowable exception to the requirements of a Specification.
Unplanned events may satisfy the requirements (including applicable acceptance criteria) for a given SR.

Discussien of Ching2s S;cticn 3.0 - LC0 cnd SR Applicability ADMINISTRATIVE CHANGES A.11 The technical content of CTS 4.0.5 has been moved to ITS Specification 5.5.8, " Inservice Testing Program". Any technical changes to this requirement are addressed in the Discussion of Changes for Section 5.5.
The movement of these requirements within the TS is considered administrative.
This change is consistent with NUREG-1431.
A.12 The CTS for each unit is currently contained within separate
~ volumes.
The ITS combines both Units 1 and 2 into a single volume, consistent with the CTS prior to Amendments 148 and 142.
ITS LCO 3.0.8 and SR 3.0.5 are added to clearly state that each individual specification and surveillance requirement applies to each unit independently, unless otherwise specifically stated.
In those instances, the specification or surveillance denotes limits for each unit individually, or the specification is identified as only being applicable to a particular unit.
This is consistent with CTS 3.0.5 and 4.0.6 which existed prior to the above amendments.
This change is administrative since it only restates the requirements which already exist when each unit is provided in
. separate volumes and maintains all of the technical requirements.
