BASIS The reactor protection system automatically initiates a reactor scram to:

1. Preserve the integrity of the fuel cladding. 2. Preserve the. integrity of the reactor coolant system. 3. Minimize the energy which must be absorbed following a loss of l-coolant accident, and prevent inadvertent-criticality. When there is not fuel in the reactor, the scram serves no function; therefore, the reactor protection system is not required-to be operable Allowed out of service times for repair and surveillance testing for Reactor Protection System Instrumentation have been determined in accordance with General Electric report NEDC-30851P-A, " Technical I. Specification Improvement Analyses for BWR Reactor Protection System," l General Slectric Company, March 1988. \\. The reactor protection system is of the dual channel type (Reference subsection 7.2 FSAR). The system is made up of two independent trip systems, each having two subchannels of tripping devices. Each subchannel has an input from at least one instrument channel which . monitors a critical parameter. The outputs of the subchannels are combined in a 1 out of 2 logic; i.e., an input signal on either one or both the subchannels will cause a trip system trip. The outputs of the trip systems are arranged so that a trip on both systems is required to produce a reactor scram. This system meets the intent of IEEE - 279 for Nuclear Power Plant Protection Systems..The system has a reliability greater than that of a 2 out of 3 system and somewhat less than that of a 1 out of 2 system. With the exception of the Average Power Range Monitor (APRM) channels, the Intermediate Range Monitor (IRM) channels, the Main Steam Isolation Valve closure and the Turbine stop valve closure, each subchannel has one instrument channel. When the minimum condition for operation on the number of operable-instrument channels per untripped protection trip system is met or if it cannot be met and the affected protection trip system is placed in a tripped condition, the effectiveness of the protection system is preserved. ] Three APRM instrument channels are provided for each protection trip system. APRM's A and E operate contacts in one subchannel and APRM's C and E operate contacts in the other subchannel. APRM's B, D and F I-are arranged similarly in Amendment No. E, 203 f-l (

Unit 2 PBAPS i 32 RAggg In addition to reactor protection instrumentation which initiates a reactor scram, protective instrumentation has been provided which initiates action to mitigate the consequences of accidents which are beyond the operator's ability to control, or terminates operator errors before they result in serious consequences. This set of specifications provides the limiting conditions of operation for the primary system isolation function, initiation of the core cooling systems, control rod block and standby gas treatment systems. The objectives of the Specifications are (i) to assure the effectiveness of the protective instrumentation when required even during periods when portions of such systems are out-of-service for maintenance, and (ii) to prescribe the trip settings required to assure adequate performance. P 1 Channel functional test frequencies and allowed out of service times for repair and surveillance testing for Isolation Instrumentation have been determined in accordance with General Electric reports NEDC-30851P-A, Supplement 2, " Technical Specification Improvement Analysis for BWR Isolation Instrumentation Common to RPS and ECCS Instrumentation," and NEDC-31677P-A," Technical Specification Improvement Analyses for BWR Isolation Actuation Instrumentation." The AOT is 12 hours for Table 3.2.A Items 1, 4, and 5 because these items have instrumentation that is common to the RPS. Other Table 3.2.A Items have an AOT of 24 hours. Channel functional test frequencies and allowed out of service times for repair and surveillance testing for ECCS Actuation Instrumentation have been determined in accordance with General Electric reports NEDC-30936P-A,"BWR Owners' Group Technical Specification Improvement Methodology with Demonstration for BWR ECCS Actuation Instrumentation," Parts 1 and 2, and RE-022," Technical Specification Improvement Analysis for the Emergency Core Cooling System Actuation Instrumentation for Peach Bottom Atomic Power Station, Units 2 and 3." Channel functional test frequencies and allowed out of service times for repair and surveillance testing for miscellaneous instruments have been determined in accordance with General Electric report GENE-770-06-1," Bases for t Changes to Surveillance Test Intervals and Allowed Out-of-Service Times for Selected Instrumentation Technical s Specifications," and the associated NRC Safety Evaluation Report dated July 21, 1992. Channel functional test frequencies and allowed out of service times for repair and surveillance testing for RCIC instrumentation have been determined in accordance with Amendment No. 111, 141, 203 n p Unit 2 PGAPS 3.2 BASES. (continued)' .{ 'I General Electric report GENE-770-06-2," Bases for Changes to l L, Surveillance-. Test Intervals.'and Allowed Out-of-Service Times. for Selected Instrumentation Technical Specifications," and i the associated:NRC-Safety Evaluation Report dated September 13,'1991. l Some of 'the settings on the instrument!ation that initiate or. control core'and containment cooling have tolerances ( explicitly stated where the high and' low values are both-j critical;and may have a' substantial effect on safety.. The' ' set points of:other: instrumentation, where.only the high.or low end of the setting has a. direct bearing on safety, are- { chosen at a level away from the normal operating range to. j prevent inadvertent actuation of-the safety system involved and exposure to abnormal situations. 1 Actuation of primary containment valves is initiated by f protective' instrumentation shown in Table 3.2.A which senses the conditions for which isolation is required. Such instrumentation must be available whenever primary i containment integrity is required. i e The instrumentation which initiates primary system isolation is connected in a dual bus arrangement. The low water level instrumentation set to trip at zero inches indicated level (538 inches above vessel zero) closes all isolation valves except those in Groups 1,'4 and.5. l Details of valve grouping and required closing times are given in Specification 3.7. For valves which isolate at i this level, this trip setting'is adequate to prevent the core from being uncovered in the case of a break in.the i largest line assuming ~a 60 second valve closing time. 1 Required closing times are less than this. The low-low reactor water level instrumentation is set to trip when reactor water level is minus_48-inches indicated { 1evel (490 inches above vessel zero). This trip initiates j HPCI, RCIC, Alternate Rod Insertion and trips the recirculation pumps. The low-low-low reactor water level instrumentation.is set to trip tehen the reactor water level j is minus 160 inches indicated level (378 inches above vessel i zero). This trip closes Main Steam Line Isolation Valves, i Main Steam Drain Valves and Recirc Sample Valves (Group 1), j activates the remainder of the CSCS subsystem, and starts i a ~ i l -89a-Amendment No. 203 ~.. I

Unit 2 PBAPS 3.2 BASES (Cont'd) Pressure instrumentation is provided to close the main steam isolation valves in RUN Mode when the main steam line pressure drops below 850 psig. The Reactor Pressure Vessel thermal transient due to an inadvertent opening of the turbine bypass valves when not in the RUN Mode is less severe than the loss of feedwater analyzed in section 14.5 of the FSAR; therefore, closure of the Main Steam isolation valves for thermal transient protection when not in RUN Mode is not required. The HPCI high flow and temperature instrumentation are provided to detect a break in the HPCI steam piping. Tripping of this instrumentation results in actuation of HPCI isolation valves. Tripping logic for the high flow is 1 out of 2 logic. Temperature is monitored at four (4) locations with four (4) temperature sensors at each location. Two (2) sensors at each location are powered by "A" DC control bus and two (2) by "B" DC control bus. Each pair of sensors, e.g., "A" or "B" at each location are physically separated and the tripping of either "A" or "B" bus sensor will actuate HPCI isolation valves. The trip settings of s 300% of design flow for high flow and 200 degrees F for high temperature are such that core uncovery is prevented and fission product release is within limits. The RCIC high flow and temperature instrumentation are arranged the same as that for the HPCI. The trip setting of s 300% for high flow and 200 degrees F for temperature are based on the same criteria as the HPCI. The Reactor Water Cleanup System high flow instrumentation is arranged similar to that for the HPCI System. The trip settings are such that core uncovery is prevented and fission product release is maintained within limits. The high temperature instrumentation downstream of the non-regenerative heat exchanger is provided to protect the ion exchange resin in the demineralizer from damage due to high temperature. Such damage could impair the resins' ability to remove impurities from the primary coolant and possibly result in the release of previously captured impurities back into the coolant in large concentrations. The instrumentation which initiates CSCS action is arranged in a dual bus system. As for other vital instrumentation arranged in this fashion, the Specification preserves the effectiveness of the system even during periods when maintenance or testing is being performed. An exception to this is when logic functional testing is being performed. The control rod block functions are provided to prevent excessive control rod withdrawal so that MCPR does not decrease to the fuel cladding integrity safety limit. The trip logic for this function is 1 out of n: e.g., any trip on one of 6 APRM's, 8 IRM's, or 4 SRM's will result in a rod block. The minimum instrument channel requirements assure sufficient instrumentation to assure the single failure criteria is met. Amendment No. 45, 43, 70, 104, 203

i s Unit 3 i 3 PBAPS i BASES The~ reactor protection system automatically initiates a reactor scram j to: i 1. Preserve the integrity of the fuel cladding. l 2. Preserve the integrity of the reactor coolant system. 3. Minimize the energy which must be absorbed following a^ loss of- ~ l coolant accident, and prevent inadvertent criticality. i When there is not fuel in the reactor, the scram serves no function; [ therefore, the reactor protection system is not-required to be operable. s Allowed out of service times for repair and surveillance testing _for Reactor Protection System Instrumentation have been determined in l accordance with General Electric report NEDC-30851P-A, " Technical i Specification Improvement Analyses for BWR Reactor Protection System," 8 General Electric Company, March 1988. The reactor protection system is.of the dual channel type (Reference } subsection 7.2 FSAR). The system is made up of two. independent trip systems, each having two subchannels of tripping devices. Each subchannel has an input from at least one instrument channel which monitors a critical parameter. i i The outputs of the subchannels are combined in a 1 out of 2 logic; i.e., an input signal on either one or both the subchannels will cause a trip system trip. The outputs of the trip systems are arranged so j that a trip on both systems is required to produce a reactor scram. .i This system meets the intent of IEEE. - 279 for Nuclear Power Plant Protection Systems. The system has a reliability greater than that of i a 2 out of 3 system and somewhat less than that of a 1 out of 2 i system. With the exception of the Average Power Range Monitor (APRM) channels, j the Intermediate Range Monitor (IRM) channels, the Main Steam j Isolation Valve closure and the Turbine stop valve closure, each -subchannel has one instrument channel. When the minimum condition for operation on the number of operable instrument channels per untripped protection trip system is met or if it cannot be met and the affected protection trip system is placed in a tripped condition, the effectiveness of the protection system is preserved. 1 Three APRM instrument channels are provided for each protection trip f system. APRM's A and E operate contacts in one subchannel and APRM's l C-and E operate contacts in the other subchannel. 'APRM's B, D and F are arranged similarly in -47 Amendment No. G4, 206 l i I

If the first column cannot be met for one of the two trip systems, this condition may exist for up to seven days provided that during that time the operable system is functionally tested immediately and daily thereafter; if this condition lasts longer than seven days, the system shall be tripped. If the first column cannot be met for both trip systems, the systems shall be tripped. 2. W = Loop Recirculation flow in percent of design. Trip level setting is in percent of rated power (3293 MWt). 1 AW is the difference between two loop and single loop effective recirculation drive flow rate at the same core flow. During single loop operation, the reduction in trip setting is accomplished by correcting the flow input of the flow biased rod block to preserve the' i original (two loop) relationship between the rod block setpoint and recirculation drive flow. AW = 0 for two loop operation. 3. IRM downscale is bypassed when it is on its lowest range. 4. This function is bypassed when the count rate is 2100 cps. 5.

Unit 3 PBAPS 32 BAggg In addition to reactor protection instrumentation which initiates a reactor scram, protective instrumentation has been provided which initiates action to mitigate the consequences cf accidents which are beyond the operator's ability to control, or terminates operator' errors before they result in serious consequences. This set of specificatione provides the limiting conditions of operation for the primary system isolation function, initiation of the core cooling systems, control rod block and standby gas treatment systems. The objectives of the Specifications are (1) to assure the effectiveness of the protective instrumentation when. required even during periods when portions of such systems are out-of-service for maintenance, and (ii) to prescribe the trip settings required to assure adequate performance. Channel functional test frequencies and allowed out of service times for repair and surveillance testing for Isolation Instrumentation have been determined in accordance with General Electric reports NEDC-30851P-A, Supplement 2, " Technical Specification Improvement Analysis for BWR Isolation Instrumentation Common to RPS and ECCS Instrumentation," and NEDC-31677P-A," Technical Specification Improvement Analyses for BWR Isolation Actuation Instrumentation." The AOT is 12 hours for Table 3.2.A Items 1, 4, and 5 because these items have instrumentation that is common to the RPS. Other Table 3.2.A Items have an AOT of 24 hours. Channel functional test frequencies and allowed out of service times for repair and surveillance testing for ECCS Actuation Instrumentation have been determined in accordance with General Electric reports NEDC-30936P-A,"BWR Owners' Group Technical Specification Improvement Methodology with Demonstration for BWR ECCS Actuation Instrumentation," Parts 1 and 2, and RE-022," Technical Specification Improvement Analysis for the Emergency Core Cooling System Actuation Instrumentation for Peach Bottom Atomic Power Station, Units 2 and 3." Channel functional test frequencies and allowed out of service times for repair and surveillance testing for miscellaneous instruments have been determined in accordance with General Electric report GENE-770-06-1," Bases for Changes to Surveillance Test Intervals and Allowed out-of-Service Times for Selected Instrumentation Technical Specifications," and the associated NRC Safety Evaluation Report dated July 21, 1992.

the associated NRC Safety' Evaluation Report dated September 13, 1991. Some of the settings on the instrumentation that initiate or control core and containment cooling have tolerances explicitly stated where the high and low values are both j critical and may have a substantial effect on safety. The 1 set points of other instrumentation, where only the high or low and of the setting has a' direct bearing on safety, are chosen at a-level away from the normal ~ operating range to prevent inadvertent actuation of the safety system involved and exposure to abnormal situations. I Actuation of primary containment valves is initiated by. protective instrumentation'shown in Table 3.2.A which senses the conditions for which isolation is required. Such instrumentation must be available whenever primary containment integrity is required. The instrumentation which initiates primary system isolation is-connected in a dual bus arrangement. The low water level instrumentation set to trip at'zero inches indicated level (538 inches above vessel zero) closes all isolation valves except those in Groups 1, 4 and 5. Details of valve grouping and required closing times are given in Specification 3.7. For. valves which isolate at 'this level, this trip setting is adequate to prevent the core from being uncovered in the case of a break in the 1 ' largest line assuming a 60 second valve closing time. { Required closing times are less than this. ) 1 The low-low reactor water leve1' instrumentation is set to l trip when reactor water level'is minus 48 inches indicated level (490 inches above vessel zero). This trip initiates HPCI, RCIC, Alternate Rod Insertion and trips the recirculation pumps. The low-low-low reactor water level instrumentation is set to trip when'the reactor water level is minus 160 inches indicated level (378 inches above vessel zero). This trip closes. Main Steam Line Isolation valves, 1 Main Steam Drain Valves and Recirc Sample Valves (Group 1), activates the remainder of the CSCS subsystem, and starts i -89a-Amendment No. 206

b i Unit 3 PBAPS l 3.2 BASES (Cont'd) Pressure instrumentation is provided to close the main steam isolation valves in RUN Mode when the main steam line pressure drops below 850 i psig. The Reactor Pressure Vessel thermal transient due to an inadvertent opening of the turbine bypass valves when not in the RUN Mode i is less severe than the loss of feedwater analyzed in section 14.5 of the FSAR; therefore, closure of the Main Steam isolation valves for thermal transient protection when not in RUN Mode is not required. The HPCI high flow and temperature instrumentation are provided to detect a break in the HPCI steam piping. Tripping of this instrumentation results in actuation of HPCI isolation valves. Tripping logic for the high flow is 1 out of 2 logic. Temperature is monitored at four (4) locations with four (4) temperature sensors at each location. Two (2) sensors at each location are powered by "A" DC control bus and two (2) by '"B" DC control bus. Each pair of sensors, e.g., "A" or "B" at each location are physically separated and the tripping of either "A" or "B" bus sensor will actuate HPCI isolation valves. The trip settings of s 300% of design flow for high flow and 200 degrees F for high -temperature are such that core uncovery is prevented and fission product release is within limits. The RCIC high flow and temperature instrumentation are arranged the same I as that for the HPCI. The trip setting of s 300% for high flow and 200 degrees F for temperature are based on the same criteria as the HPCI. The Reactor Water Cleanup System high flow instrumentation is arranged similar to that for the HPCI System. The trip settings are such that core uncovery is prevented and fission product release is maintained within limits. The high temperature instrumentation downstream of the i non-regenerative heat exchanger is provided to protect the ion exchange resin in the demineralizer from damage due to high temperature. Such damage could impair the resins' ability to remove impurities from the primary coolant and possibly result in the release of previously captured impurities back into the coolant in large concentrations. The instrumentation which initiates CSCS action is arranged in a dual bus i system. As for other vital instrumentation arranged in this f'shion, the a Specification preserves the effectiveness of the system even during periods when maintenance or testing is being performed. An exception to this is when logic functional testing is being performed. The control rod block functions are provided to prevent excessive control rod withdrawal so that MCPR does not decrease to the fuel cladding integrity safety limit. The trip logic for this function is 1 out of n: e.g., any trip on one of 6 APRM's, 8 IRM's, or 4 SRM's will result in a rod block. f The minimum instrument channel requirements assure sufficient instrumentation to assure the single failure criteria is met. !
