LCA 117, Rev. 2 Page 4 of 42 2.2 LIMITING SAFETY SYSTEM SETTINGS BASES 2.2.1 REACTOR TRIP SYSTEM INSTRUMENTATION SETPOINTS i

The Reactor Trip Setpoint Limits specified in Table 2.2-1 are the 1

values at which the Reactor Trips are set for each parameter. The Trip Setpoints have been selected to ensure that the reactor core and reactor j

coolant system are prevented from exceeding their safety limits. Opera-tion with a trip set less conservative than its Trip Setpoint but within j

its specified Allowable Value is acceptable on the basis that each Allowable Value is equal to or less than the drif t allowance assumed for each trip in the safety analyses.

Manual Reactor Trip The Manual Reactor Trip is a redundant channel to the automatic protective instrumentation channels and provides manual reactor trip capability.

Power Range. Neutron Flux The Power Range, Neutron Flux channel high setpoint provides reactor core protection against reactivity excursions which are too rapid to be protected by temperature and pressure protective circuitry. The low set point provides redundant protection in the power range for a power excursion beginning from low power. The trip associated with the low setpoint may be manually bypassed when P-10 is active (two of the four power range channels indicate a power level of above approximately 10 percent of RATED THERMAL POWER) and is automatically reinstated when P-10 becomes inactive (three of the four channels indicate a power level below approximately 10 percent of RATED THERMAL POWER).

i Power Range Neutron Flux. High Positive Rate l

The Power Range Positive Rate trip provides added protection against l-rapid flux increases which are characteristic of rod ejection events from any power level. Specifically, this trip complements the Power Range Neutron Flux High and Low trips to ensure that the criteria are met for rod ejection from partial power. No credit was taken for operation of this trip in the accident analyses; however, its functional capability at the specified trip setting is required by this specification to enhance the overall reliability of the Reactor Protection System.

Power Range. Neutron Flux. High Negative Rate l

The Power Range Negative Rate trip provides protection to ensure that I

the minimum DNBR is maintained above the design DNBR value for multiple control rod drop accidents. The analysis of a single control rod drop accident _ indicates a return to full power may be initiated by the TROJAN-UNIT 1 B 2-3 Amendment No.

LCA 117, Rev. 2 Page 5 of 42 LIMITING SAFETY SYSTEM SETTINGS BASES automatic control system in response to a continued full power turbine load demand or by the negative moderator temperature feedback. This transient will not result in a calculated DNBR of less than the design DNBR value, therefore single rod drop protection is not required.

Intermediate and Source Range. Nuclear Flux The Intermediate and Source Range, Nuclear Flux trips can provide reactor core protection during reactor startup. These trips provide added protection to the low setpoint trip of the Power Range, Neutron Flux channels The Source Range Channels will initiate a reactor trip at about10hountspersecondunlessmanuallyblockedwhenP-6becomes 4

active. The Intermediate Range Channels will initiate a reactor trip at a current level proportional to approximately 25 percent of RATED THERMAL POWER unless manually blocked when P-10 becomes active. No credit was taken for operation of the trips associated with either the Intermediate or Source Range Channels in the accident analyses. However, their functional capability including the specified trip settings is required by this specification to enhance the overall reliability of the Reactor Protection System and to' provide indication of core neutron flux to the operators during shutdown and startup conditions.

Overtemperature aT The Overtemperature AT trip provides core protection to prevent DNB for all combinations of pressure, power, coolant temperature, and axial power distribution, provided that the transient is slow with respect to piping transit delays from the core to the temperature detectors (about 4 seconds), and pressure is within the range between the High and Low Pressure reactor trips. This setpoint includes corrections for changes in density and heat capacity of water with temperature and dynamic com-pensation for piping delays from the core to the loop temperature detectors. With normal axial power distribution, this reactor trip limit is always below the core safety limit as shown in Figure 2.1-1.

If axial peaks are greater than design, as indicated by the dif ference between top and bottom power range nuclear detectors, the reactor trip is automatically reduced according to the notations in Table 2.2-1.

Operation with a reactor coolant loop out of service below the 4 loop P-8 setpoint does not require reactor protection system setpoint modification because the P-8 setpoint and associated trip will prevent DNB during 3 loop operation exclusive of the Overtemperature AT setpoint.

Three loop operation above the 4 loop P-8 setpoint is permissible after resetting the K1, K2 and K3 inputs to the Overtemperature AT channels and raising the P-8 setpoint to its 3 loop value.

In this mode of operation, the P-8 interlock and trip functions as a High Neutron Flux trip at the reduced power level.

LIMITING SAFETY SYSTEM SETTINGS BASES Overoower AT I

The Overpower AT reactor trip provides assurance of fuel integrity, e.g., no melting, under all possible overpower conditions, limits the required range for Overtemperature AT protection, and provides a backup to the High Neutron Flux trip. The setpoint includes corrections for changes in density and heat capacity of water with temperature, and i

dynamic compensation for piping delays from the core to the loop tempera-I ture detectors. No credit was taken for operation of this trip in the 1

accident analyses; however, its functional capability at the specified i

trip setting is required by this specification to enhance the overall reliability of the Reactor Protection System.

Pressurizer Pressure I

The Pressurizer High and Low Pressure trips are provided to limit the pressure range in which reactor operation is permitted. The High Pressure trip is backed up by the pressurizer code safety valves for RCS overpressure protection, and is therefore set lower than the set pressure for these valves (2485 psig). The Low Pressure trip provides protection when above the P-7 interlock setpoint by tripping the reactor l

in the event of a loss of reactor coolant pressure.

Pressurizer Water level The Pressurizer High Water Level trip provides added protection against Reactor Coolant System overpressurization when above the P-7 interlock setpoint by limiting the water -level to a volume sufficient to I

retain a steam bubble and preventing water relief through the pressurizer safety valves. No credit was taken for operation of this trip in the accident analyses; however, its functional capability at the specified trip setting is required by this specification to enhance the overall reliability of the Reactor Protection System.

Loss of Flow The Loss of Flow trips provide core protection to prevent DNB in the event of a loss of one or more reactor coolant pumps.

i Above approximately 10% (P-7) but below approximately 39% (P-8) of

[

RATED THERMAL POWER, an automatic reactor trip will occur if the flow in any two loops drops below 90% of nominal full loep flow. Above approxi-i mately 39% (P-8) of RATED THERMAL POWER, an automatic reactor trip will occur if the flow in any single loop drops below 90% of nominal full TROJAN-UNIT 1 B 2-5 Amendment No. 48, i

LCA 117, Rev. 2 4 -

Page 7 of 42 LIMITING SAFETY SYSTEM SETTINGS BASES loop flow. This latter trip will prevent the minimum value of the DNBR f rom going below 1.73 during nornal operational transients and anticipated transients when 3 loops are in operation and the Over-temperature AT trip setpoint is adjusted to the value specified for all loops in operation. With the Overtemperature aT trip setpoint adjusted to the value specified for 3 loop operation, the P-8 trip at 75% RATED THERMAL POWER will prevent the minimum value of the DNBR from going below 1.73 during normal operational transients and anticipated transients with 3 loops in operation.

Steam Generator Water Level The Steam Generator Water Level Low-Low trip provides core protec-tion by preventing operation with the steam generator water level below the minimum volume required for adequate heat removal capacity. The specified setpoint provides allowance that there will be sufficient water inventory in the steam generators at the time of trip to allow for starting delays of the auxiliary feedwater system.

Steam /Feedwater Flow Mismatch and Low Steam Generator Water level The Steam /Feedwater Flow Mismatch in coincidence with a Steam Generator low Water Level trip is not used in the transient and accident analyses but is included in Table 2.2-1 to ensure the functional capa-bility of the specified trip settings and thereby enhance the overall reliability of the Reactor Protection System. This trip provides added protection to the Steam Generator Water Level Low-Low trip. The Steam /

FeedwaterFlowMismatchportionofthistrip{sactivatedwhenthesteam flow exceeds the feedwater flow by >l.51 x 10 lbs/ hour. The Steam l

Generator low Water level portion of the trip is activated when the water level drops below 25 percent, as indicated by the narrow range instrument.

These trip values include sufficient allowance in excess of normal operating values to preclude spurious trips but will initiate a reactor trip before the steam generators are dry. Therefore, the required capacity and starting time requirements of the auxiliary feedwater pumps are reduced and the resultiny thermal transient on the Reactor Coolant System and steam generators is minimized.

Undervoltage and Underfrecuency - Reactor Coolant Pumo Busses The Undervoltage and Underfrequency Reactor Coolant Pump bus trips provide reactor core protection when above the P-7 interlock setpoint against DN8 as a result of loss of voltage (nominally 12.47 kV) or TROJAN-UNIT 1 8 2-6 Amendment No. #8,

BASES i

l underf requency (nominally 60 Hz) to more than one reactor coolant pump.

l The specified setpoints assure a reactor trip signal is generated before the low flow trip setpoint is reached. A 0.1 second time delay in the underfrequency trip and a 0.2 second time delay in the undervoltage trip are incorporated to prevent spurious reactor trips from momentary electrical power transients.

Turbine TriD A Turbine Trip causes a direct reactor trip when operating above the P-7 interlock setpoint.

Each of the turbine trips provide turbine l

protection and reduce the severity of the ensuing transient. No credit was taken in the accident analyses for operation of these trips. Their j

functional capability at the specified trip settings is required to enhance the overall reliability of the Reactor Protection System.

4 Auto Safety Injection InDut l

4 If a reactor trip has not already been generated by the reactor protective instrumentation, the ESF automatic actuation logic channels will initiate a reactor trip upon any signal which initiates a safety injection. This trip is provided to protect the core in the event of a LOCA. The ESF instrumentation channels which initiate a safety injection signal are included in Table 3.3-3.

l Reactor Coolant Pumo Breaker Position TriD The Reactor Coolant Pump Breaker Position Trip.is an anticipatory trip which provides additional reactor core protection against DNB resulting from the opening of two or more pump breakers when above the P-7 interlock setpoint. The open/close position trip assures a reactor trip signal is generated before the low flow trip set point is reached. No credit was taken in the accident analyses for operation of this trip. The functional l

capability at the open/close position settings is required to enhance the overall reliability of the Reactor Protection System.

3/4.0 APPLICABILITY SAFETY LIMITS AND LIMITING SAFETY SYSTEM SETTINGS The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveil-lance Requirements within Section 3/4.

3.0.1 This specification defines the applicability of each specification in terms of defined OPERATIONAL MODES or other specified conditions and is provided to delineate specifically when each specification is applicable.

3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.

3.0.3 This specification delineates the ACTION to be taken for circumstances not directly provided for in the ACTION statements and whose occurrence would violate the intent of the specification.

For example, Specification 3.5.1 calls for each Reactor Coolant System accumulator to be OPERABLE and provides explicit ACTION requirements when one accumulator is inoperable. Under the terms of Specification 3.0.3, if more than one accumulator is inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> measures must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. As a further example Specification 3.6.2.1 requires two Containment Spray Systems to be 4

1 OPERABLE and provides explicit ACTION requirements if one spray system is j

inoperable: Under the terms of Specification 3.0.3, if both of the required Containment Spray Systems are inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> measures must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in at least COLD SHUTDOWN in the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

It is assumed that the unit is brought to the required MODE within the required times by promptly initiating and carrying out the appropriate ACTION statement.

3.0.4 This specification provides that entry into an OPERABLE MODE or other specified applicability condition must be made with (a) the full complement of required systems, equipment or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.

The intent of this provision is to insure that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded.
