-* . SLRVEILLANCE SR 3.3.1.9

. REQUIREENTS (continued) SR 3.3.1.9 is the )erformance of a CHAML CALIBRATION every 24 months. This St is modified by a Note stating that neutron detectors are excluded from the CHNSEL CALIBRATION.

The CHM 0EL CALIBRATION for the )ower range neutron detectors consists of a normalization of tw detectors based on a power calcrimetric and flux ma) performed above 20% RTP. Below 20% RTP, the design of tw incore detector system, low core power density, and detector accuracy make use of the incore detectors inadequate for use as a reference standard for .

comparison to the excore channels. The CHANNEL CALIBRATION for the source range and intermediate range neutron detectors consists of obtaining the detector plateau or discriminator curves, evaluating those curves preampand comparing-

' the curves to the manufacturer's data. This Surveillance is not required for the power range detectors for entry into MODE 2 and 1, and is not required for the intermediate range detectors for entry into MODE 2. because the plant must be in at least MODE 2 to perform the test for the intermediate range detectors and MODE 1 for the power range detectors.

The 24 month Frequency is based on the need to perfons this Surveillance under the conditions that apply during a plant outage and the potential for an unalanned transient if the Surveillance were performed with tw reactor at power.

O mrating experience has shown these components usually pass tw Surveillance when performed on the 24 month Frequency.

SR 3.3.1.10 SR 3.3.1.10 is the performance of a TADOT of the Manual Reactor Trip, "CP E d:r "nitba, and the SI. ADS Actuation, and CNT Injection inputs from the ESFACs. This TADOT is performed every 24 months. The test shall L independently verify the OPERABILITY of the undervoltage and shunt trip mechanisms for the Manual Reactor Trip Function for the Reactor Trip Breakers.

The Frequency is based on the known reliability of the Functions and the multichannel redundancy available, and has

been shown to be acceptable through operating experience.

2 The SR is modified by a Note that excludes verification of setpoints from the TA00T. The Functions affected have no setpoints associated with them.

This Function is necessary in H0 DES 1 and 2, and 3 above P 11 to mitigate the effects of a large SLB or a large Feed 11ne Break (FLB). Failure to trip the turbine following a SLB or FLB can lead to additional mass and energy being delivered to the steam generators, resulting in excessive cooldown and additional mass and energy release in containment. In H0 DES 4, 5, and 6. the energy in the RCS and the steam generators is low and this function is not required to be OPERABLE.

This Function is actuated by Steam Generator Water Level - High 2, by a Safeguards Actuation signal, or manually. The Reactor Trip Signal also initiates a turbine trip signal whenever a reactor trip (P 4) is generated.

11. Reactor Coolant Pump Trip -

Reactor Coolant Pump (RCP) Trip allows the passive injection of borated water into the RCS. Injection provides RCS makeup water and boration during transients or accidents when the normal makeup supply from the CVS is lost or insufficient. Two tanks provide )assive injection of borated water by gravity when t1e reactor coolant pumas are tripped. CMT injection mitigates the effects of ligh energy line breaks by adding primary side water to ensure maintenance or recovery of reactor vessel water level following a LOCA, and by borating to ensure recovery or maintenance of SHUTDOWN MARGIN following a steam line break. RCP trip on high bearing water temperature protects the RCP coast down. RCP trip is actuated by High RCP bearing water temperature ADS Stages 1, 2, and 3 Actuation (Function 9) and CMT actuation.

- (continued)

REQUIREMENTS one channel to a similar parameter on other channels. It is based on the assumption that instrument channels monitoritg the same parameter should read a> proximately the same value.

Significant deviations between tie two instrument channels could be an indication of excessive instrument drift in ore of the channels or even something more serious. A Cf%NNEL CHECK will detect gross channel failure; thus, it is key to verifying the instrumentation continues to operate properly between each CHANNEL CALIBRATION.

Agreement criteria are determined by the plant staff, bar.ed un a combination of the channel instrument uncertainties, including indication and readability. If a channel is outside the match criteria, it may be an indication that the sensor or the signal processing equipment has drifted outside its limit.

The Surveillance Frequency is based on operating experience that demonstrates channel fail'are is rare. Automated o;>erator aids may be used to facilitate performance of the-CiANNEL CHECK.

SR 3.3.2_.2 SR 3.3.2.2 is the performance of an ACTUATION LOGIC TEST.

The ESFAC and PLCs within a division are tested every 92 days on a STAGGERED TEST BASIS using the automatic tester. One half of the microprocessor subsystems in a division are tested while the remaining microprocessor subsystems continue to provide protection. Then the second half is tested while the first half provides protection. Through the automatic tester, the possible logic conditions, with and without applicable permissives, are tested for each ESF Function.

Prior to the start of testing, the calibration of tha automatic tester shall be verified and adjustments made as required. After the automatic tester has completed the tests of the ESFAC and PLCs within the division. the results of the automatic test shall be reviewed to verify completeness and

- adequacy of results.

REQUIREMENTS exceeds the Trip Setpoint value at the sensor, to the point  ;

at which the equipment reaches the required functional state ,

(e.g., valves in full open or closed position).

~

For channels that include dynamic transfer functions (e.g..

lag lead / lay rate / lag, etc.). the response time test may be performed with the transfer functions set to one with the resulting measured respouse time compared to the appropriate SSAR (Ref. 2) response time. Alternately, the response time test can be perforr.,cd with the time constants set to their  ;

nominal value provided the required response time is analytically calculated assuming the time constants are set at their nominal values. The response time may be measured by a series of overlapping tests such that the entire response time is measured.

ESF RESPONSE TIME tests are conducted on an 24 month STAGGERED TEST BASIS. Testing of the devices, which make up l the bulk of the response time, is included in the testing of each channel. The final actuation device in one train is tested with each channel. Therefore, staggered testing -

results in response time verification of these devices every '

24 months. The 24 month Frequency is consistent with the typical refueling cycle and is based on unit operating L experience, which shows that random failures of instrumentation components causing serious response time degradation, t,ut not channel failure, are infrequent ,

occurrences.

SR 3.3.2.7 SR 3.3.2.7 is the performance of an ACTUATION DEVICE TEST.

This Surveillance Requirement is applicable to the equipment which is actuated by the Protection Logic Cabinets except squib valves. The OPERABILITY of the actuated equipment is checked by exercising the equipment on an individual basis.

The Frequency of 24 months is based on the need to perforra this surveillance during periods in which sne plant is shutdown for refueling to prevent any upsets of plant x opfr_ation.  :

This test, in conjunction with the ACTUATION LOGIC TEST, demonstrates that the actuated device responds to a simulated actuation signal.

REQUIREHENTS This Surveillance Requirement is modified by a Note that states that actuated equipment, that is included 1.7 the Inservice Test (IST) Program, is exempt from this surveillance. Tr4 IST Program provides for exercising of the safety related valves on a more frequent basis. The results e from the IST Program can therefore be used to verify OPERABILITY of the final actuated equipment.

The Frequency of 24 months is based on the need to-perform this surveillance during periods in which the plant is '

shutdown for refueling to prevent any additional risks associated with inadvertent operation of the squib valves.

SR 3.3.2J t SR 3.3.h.9 is the wrformance of an ACTUATION DEVICE TEST.

This Su'veillance lequirement is applicable to the circuit breakers which de. energize the power to the pressurizer heaters upon a pressurizer heater trip. The OPERABIL!fY of thew treakers is checked by opening these breakers using the ,

Plant Control System.

The Frequency of 24 months is based on the need to perform this surveillance during periods in which the plant is shutdown for refueling to prevent any upsets of plant operation. This Frequency is adequate based on the use of multi le circuit breakers to prevent the failure of any singl circuit breaker from disabling the function and that all circuit breakers are tested.
