Process Protection System Revision: 9 Interface Requirements Specification Page 20 of 78 1.5.1 Protection Sets The PPS consists of sixteen (16) racks (per DCPP Unit) of instrumentation located in the Cable Spreading Rooms (Auxiliary Building, elevation 128). The sixteen racks are divided into four Protection Sets; five racks each for Protection Sets I and II, three racks each for Protection Sets ill and IV. Each Protection Set is physically separated and electrically isolated from the other sets.Protection Set I consists of Racks 1 thru 5 (RNP1A, RNP1B, RNP1C, RNP1D, and RNP1E). Set II consists of Racks 6 thru 10 (RNP2A, RNP2B, RNP2C, RNP2D, and RNP2E).Protection Set III consists of Racks 11 thru 13 (RNP3A, RNP3B, and RNP3C).Protection Set IV consists ofRacks 14 thru 16 (RNP4A, RNP4B, and RNP4C).Physical equipment will be assigned to specific PPS racks during detailed design.The existing Eagle 21 HMI units are located in Racks 5 (RNP1E), 9 (RNP2D), 12 (RNP3B) and 14 (RNP4A). These racks are expected to house the replacement PPS Maintenance Workstation and communications equipment. 1.5.2 Triconex Tricon Programmable Logic Controllers (PLC)The Tricon PLC shown in the following figures is composed of the Main Chassis and two Remote Expansion Chassis (RXMs), all within a given protection set. The Main Chassis is connected to a "Primary" RXM via triplicated copper I/O expansion bus cables. The Primary RXM (PRXM) is connected to a "Remote" RXM chassis using multimode fiber-optic cables. The Remote RXM (RRXM) chassis allows extending the I/O bus over longer distances than copper cables can support, and to provide electrical isolation for non-safety-related I/O signals, as required.Refer to the Triconex licensing Topical Report [1.4.5.3] for additional information. 1.5.3 Westinghouse Advanced LogicSystem (ALS)1.5.3.1 A typical ALS rack configuration as shown in the following figures contains two sets of the following components (See Reference 1.4.5.5 for additional details): ALS-1 02 -Core Logic Board (CLB)ALS-302 -Digital Input Board ALS-31 1 -Analog Input Board (Temperature) ALS-321 -Analog Input Board ALS-402 -Digital Output Board ALS-421 -Analog Output Board 1.5.3.2 ALS Service Unit (ASU)Th ASU is a dedicatedsoftware application that is-installed on tlhe-ALS Maintenance Workstation (MWS) described in Section 1.5.6 and shown in Figure 1-22. The ASU application is connected to the ALS during maintenance or testing by plant personnel. The ASU application provides non-intrusive diagnostic tools that allow plant personnel to access detailed status and configuration information of the system while the system is online.The ASU application also provides post-event analysis information about the system to plant personnel for evaluation of an event after it has occurred.The ASU application may be used to modify setpoints and tuning constants, but shall not be capable of altering functional programming (i.e., alter the Process Protection System Interface Requirements Specification Revision: 9 Page 21 of 78 algorithm) of the CLB.1.5.3.3 The ALS A and ALS B Conceptual architecture, which provides built-in diversity and defense in depth per the D3 evaluation approved by NRC[1.4.5.4], is illustrated in Figure 1-1. Wiring details are illustrated In Figure 2-5 and Figure 2-6.The manual bypass switches in Figure 1-1 allow one ALS diversity Group (i.e., ALS-A or ALS-B) to be bypassed and removed from service without tripping the channel. The manual trip switch may be used to initiate a partial channel trip independently of the ALS logic.Figure 1-1 ALS Diversity Architecture Concept De-energize to Trip Configuration Energize to Trip Configuration Note: Manual Trip switch as required by detailed design 1.5.4 Isolation Devices 1.5.4.1 The isolation devices shown in Figure 1-3, Figure 1-8, Figure 1-13, and Figure1-18are safety-related components providedby Westinghouse... 1.5.4.2 The isolation devices are separate and independent from both the Tricon and the ALS.1.5.4.3 All isolation devices are 4-20 mA DC input and 4-20 mA DC output.1.5.4.4 The qualified isolation devices shall perform the required isolation function when powered from non-safety-related I/O power. That is, credible faults (short circuit, open circuit, application of fault potential) on the Class II terminals will not adversely affect the Class I circuit. Process Protection System Revision: 9 Interface Requirements Specification Page 22 of 78 1.5.5 ALS Signal Conditioning 1.5.5.1 The ALS shall provide signal conditioning and isolation for the Reactor Coolant System (RCS) non-safety-related flow analog output signals 1.5.5.2 The ALS shall provide capability to normalize the RCS Flow scaling periodically by adjusting the gain and offset (i.e., mex+b) from within the ALS application via the ASU.1.5.5.3 The ALS shall provide signal conditioning for the RCS narrow range Resistance Temperature Detector (RTD) safety-related signals to the Overpower Delta Temperature (OPDT) and Overtemperature Delta T (OTDT) reactor trip functions, and the RCS Wide Range Temperature and Pressurizer Vapor Space Temperature RTD signals.1. The ALS shall convert the RTD signals from resistance to temperature.

2. The ALS shall provide the capability to update the resistance to temperature conversion coefficients (i.e., a, b, and c) periodically.

3. Analog temperature signal input range information is provided in the following FRS Sections: a) 3.2.3.9 (WR Hot Leg and Cold Leg Temperatures), b) 3.2.5.9 (Tavg, AT, OPDT Setpoint, OTDT Setpoint), and c) 3.2.8.9 (PZR Vapor Temp).1.5.5.4 Temperatures shall be transmitted from the ALS to the Tricon via safety-related 4-20 mA analog signals scaled as follows: 1. Narrow Range Tcold: 510 -630 deg F [FRS 3.2.5.9.1]

2. Narrow Range Thot: 530- 650 deg F [FRS 3.2.5.9.1]

3. Wide Range Thot: 0 to 700 0 F [FRS 3.2.3.9.3.a]

4. Wide Range Tcold: 0 to 700 0 F [FRS 3.2.9.3.b]

5. Pressurizer Vapor Temperature:

100 to 700 0 F [ERS 3.2.8.9.3.a]

6. The Tricon shall provide an mx+b filter on the 4-20 mA input signals per FRS 3.2.1.14.3.

1.5.5.5 If the actual temperature is below the low scale output value defined in Section 1.5.5.4 the ALS shall output the low scale value, or 0% of span=4.00 mA without initiating an Out of Range Low alarm.1.5.5.6 The ALS shall provide down-scale open RTD protection; that is, if the ALS detects an open or shorted RTD, it shall output a 0.0 mA analog signal.1.5.5.7 All temperatures shall be transmitted from the ALS to the Gateway computer via RS-422 signals scaled for the qualified range of the RTD input board.1_5.5_8. This-aiiows the-Tricon to-provide RTD-faiiure aiarming-and-ensures that the , Tricon does not indicate RTD failure when the temperature is below low scale but still functioning correctly, a condition that exists during plant shutdown 1'.5.5.9 In the latter case, the actual temperature is available from the ALS via the Gateway computer via the TxB1 data stream.1.5.5.10 Analog output signals shall fail low, if possible, upon detection of critical failure. Process Protection System Revision: 9 Interface Requirements Specification Page 23 of 78 1.5.6 Maintenance Workstation 1.5.6.1 Separate and independent Maintenance Workstation computers [Section 2.7]shown in Figure 1-22 are provided for the Tricon and ALS subsystems, respectively, for each Protection Set to allow PPS informatiOn processing and display. The two MWS computers in each Protection Set share common HMI peripheral devices such as the keyboard, video display, mouse (KVM), and touchscreen interface through a KVM switch [Section 2.3.7].1.5.6.2 The Tricon will be isolated from its dedicated Maintenance Workstation computer by the qualified safety-related Triconex Communications Module (TOM). Fiber optic cable electrically isolates the Tricon from external non-safety-related devices.1.5.6.3 The ALS broadcasts data to its dedicated Maintenance Workstation computer via the isolated one-way TxB2 RS-422 data links. TAB communications between the ALS and the MWS takes place via RS-485 data link. The TAB is physically disconnected from the MWS when the TAB is not in use. The TAB is connected and enabled only when maintenance is being performed on the ALS. It is disconnected at all other times. The TAB is enabled for short periods only when ALS maintenance is being performed, and maintenance will be performed under administrative controls by qualified individuals. This arrangement satisfies NRC DI&C ISG-04, Staff Position 10 of Section 1, Interdivisional Communications [1.4.3.4]. 1.5.6.4 A Maintenance' Workstation computer may access data only within its own protection set subsystem (i.e., Tricon or ALS). Communication with other protection sets or between subsystems within a Protection Set shall not be possible.1.5.7 Plant Process Computer Gateway and Other Non-,Safety-Related Communications Interfaces 1.5.7.1 The safety-related Tricon and ALS are connected to the non-safety-related PPC and workstation via the Gateway computer shown in Figure 1-22. The Gateway computer will be installed by PG&E in the Process Control `system (PCS) replacement project. The ALS-1 02 CLB provides isolation for the TxB1 and TxB2 one-way EIA-422 communication links to the PPC Gateway and the Maintenance Workstation, respectively. The ALS transmits data to the non-safety-related Gateway computer, which is common to all four protection sets, and to the Maintenance Workstation using serial, unidirectional, one-way communications channels that do not require any handshaking. 1.5.7.2 The Tricon will be isolated from the Gateway computer by a data isolation device such as the port aggregator network tap shown in Figure 1-22, which permits two-way communications between the Maintenance Workstation belonging to a specific protection set and the Tricon in that protection set, yetvy ev n I--U- L V %.c4L.VVay I IjJULL .:I I IE port aggregator tap will be provided by PG&E.1.5.7.3 For system health displays, the PPS will share a HMI unit in the Control Room on CC4 that will also be installed by the Process Control System (PCS) replacement project.1.5.8 Response Time The reactor trip response time is the time interval from when the monitored parameter exceeds its trip setpoint at the channel sensor, until loss of control rod Process Protection System Revision: 9 Interface Requirements Specification Page 24 of 78 stationary gripper coil voltage. The ESF response time is the time interval from when the monitored parameter exceeds its trip setpoint until the ESF equipment is capable of performing its safety function. The PPS is allocated a maximum response time of 0.409 seconds [1 .4.4.8].1.5.8.1 The ALS performs signal conditioning for the narrow range RTD's that support the Overtemperature AT (OTOT) and Overpower AT (OPDT) reactor trips, and the Tricon performs setpoint calculation and comparison and trip output. Therefore, the PPS time response allocation is shared between the ALS and Tricon portions of the PPS for these functions. 1.5.8.2 The preliminary worst case (deterministic) OTDT and OPDT PPS response time allocations shall be as follows: ALS: "0.175 seconds for RTD processing Tricon: 0.200 seconds Contingency: 0.034 seconds Total PPS Allocation: 0.409 seconds 1.5.8.3 The vendor shall provide means of verifying the actual response time if the system does not support deterministic methods of calculating worst case response time characteristics. 1.5.9 Accuracy The FRS specifies existing Eagle 21 accuracy requirements with the intent to maintain currently licensed Channel Statistical Allowance (CSA) margins such that no setpoint changes are required. Accuracy allocation between the ALS and Tricon for the RCS temperature parameters will be determined during the detailed design.

The I/O list contains the following information for each protection set. As noted below, some I/O list information is outside the scope of this interface specification. 2.1.1 I/O Power Supplies 1. Separate power supplies will be provided by PG&E for Triconex analog and digital I/O per the Triconex qualification.

2. All Tricon discrete inputs and outputs will be powered by PG&E in accordance with the requirements provided in the l/O list.3. All ALS discrete inputs and outputs will be wetted by 48 Vdc supplied by PG&E.4. The Pressurizer pressure channels are shared among the ALS, Tricon, and the control system, via qualified isolator modules, and will be powered by the Tricon ETP as shown in Figure 2-3.5. Deleted 6. All 4-20 mA analog input signals are powered from power supplies located within the PPS cabinets.

The 0-10 VDC analog signals from the Nuclear Instrumentation System (NIS) are powered by the NIS.7. PG&E will provide analog loop power supplies. Analog input loop power supply voltage should not exceed 40 Vdc, and may be as low as 24 Vdc based on the following considerations and assumptions:

a. Rosemount 1154 and 1154 Series H 1) Max qualified power supply voltage: 45 Vdc 2) Max Design loop resistance at 45 Vdc input: 1575 ohms 3) Mmn Design loop resistance at 45 Vdc input: 500 ohms 4) Max Design loop resistance at 24 Vdc input: Approx. 700 Ohms 5) Min Design loop resistance at 24 Vdc input: 0 Ohms b. Rosemount 1153 Series B&D Output Code P 1) Max qualified power supply voltage: 40 Vdc 2) Max Design loop resistance at 40 Vdc input: 1325 ohms 3) Mmn Design loop resistance at 40 Vdc input: 500 ohms 4) Max Design loop resistance at 24 Vdc input: Approx. 600 Ohms 5) Min Design loop resistance at 24 Vdc input: 0 Ohms c. Rosemount 1153 Series B&D Output Code R 1) Max qualified power supply voltage: 45 Vdc 2) Max Design loop resistance at 45 Vdc input: 1575 ohms 3) Min Design loop resistance at 45 Vdc input: 500 Ohms Process Protection System Revision:

Barton 763 max power supply voltage: 50 Vdc e. Barton 763 Max loop resistance at 40 Vdc input: Approx. 1250'ohms f. Barton 763 Mmn loop resistance at 40 Vdc input: Approx. 190 ohms g. Triconex 3805N Analog Output module OVP: 42.5 Vdc h. ALS input resistance is 200 ohms [Figure 2-2] with both "A" and "B" 302 connected in series (i.e., Rs = 100 ohms).i.Triconex 9792-610N Reg. Guide 1.180 FTP Approx. input resistance:

1) When powered from the FTP (max 48 Vdc supply): (250 + 1/(1/250 +1/3300)) = 482 ohms ~500 ohms)2) When externally powered: 250 ohms (i.e., temperature signals from the ALS)j. Resistances of external loop devices are (PG&E scope): 1) Isolator input 4-20 mA into 100 ohms (estimated)

2) Westinghouse VX-252 indicator:

5 ohms (including estimated wire resistance)

3) ERFDS: Loop-Specific (Usually 250 ohms or 50 ohms)4) RVLIS: 250 ohms k. ALS 4-20 mA analog outputs are powered by the ALS. Therefore,-

temperature inputs to the Tricon shall not use the Positive Temperature Coefficient (PTC) thermistor for loop overcurrent protection and the input resistance for Tricon temperature inputs is 250 ohms.8. Tricon Analog Output Power Supply a. Analog outputs in the safety-related Triconex Main Chassis will be powered by redundant 24 Vdc power supplies furnished by PG&E.b. Analog outputs in the non-safety related Triconex Remote RXM chassis will be powered by redundant24 Vdc power supplies furnished by PG&E and mounted in the rack housing the RRXM chassis.c. Deleted.2.1.2 Analog Inputs Figure 2-2, Figure 2-3, and Figure 2-4 illustrate typical PPS analog input signal wiring[1.4.5.6, 1.4.5.7]: 1. PT-455 signal shared among Tricon (DTT-IA functions), ALSA, ALS-B and an isolation device 2. LT-459 Signal shared among Tricon, ControBad ad an device 3. PT-5OS signal shared among the Tricon, and an isolation device 4. RCS Temperature signals are conditioned by ALS-A and ALS-B, respectively before they are input to the Tricon. Example wiring for these signals is shown in Figure 2-3.5. Tricon Al card type 3721N shall be configured for 14-bit resolution, unipolar.These cards are used for all 4-20 mA analog inputs to the PPS*6. Tricon Al cards 3703E (where used) and 3703EN shall be selected for 0-10 Vdc input, fail downscale. These cards are used for Nuclear Instrumentation (NI)inputs to the PPS. Process Protection System Revision: 9 Interface Requirements Specification Page 52 of 78 7. Signals from redundant field devices shall be processed on separate input boards (Not applicable to ALS).2.1.3 Discrete Inputs Signals from redundant field devices shall be processed on separate input boards (Not applicable to ALS).2.1.4 Discrete Outputs Figure 2-5 and Figure 2-6 illustrate typical ALS discrete output signal wiring that implements the diversity architecture [Figure 1-1] using a Line Sense Module (LSM)to provide a hardwired OR configuration between Diversity Groups ALS-A and ALS-B and to enable the ALS to perform continuous error checks.Upon detecting the following conditions, noted actions shall be taken: 1. Failure to Trip on Demand Close ALS Failure contact 2. Trip without Demand Close ALS Trouble contact The LSM is illustrated in Figure 2-1. Configuration of the LSM for use in an Energize to Trip (ETT) or Deenergize to Trip (DTiT) circuit is done through field wiring terminations on the LSM and does not require any modification of any electrical properties of the LSM itself. Thus, a single LSM can be used in an ETT or DTT circuit without the need to electrically configure the module for the trip circuit type before use.

PPS Failure Alarm due to failure to set trip on demand shall not be suppressed when the bistable is being tested in trip or bypass mode, except that the P-i13 Failure to set trip on demand MAS alarm shall be suppressed if the P-13 bistable bypass is initiated as in 2.6.6.3.h, above.4. Maintenance modes allowable under 3.c.(3) above shall include: 1. Test in Bypass: The bistable trip output is maintained in the untripped condition while in this mode; that is, Test in Bypass mode shall override the output of the channel trip comparator to prevent generation of a partial trip from the channel being tested.2. Test in Trip: The bistable trip output is mnaintained in the tripped condition while in this mode; that is, Test in Trip mode shall override the output of the channel trip comparator to initiate partial trip or actuation from the channel being tested.5. Parameter Update: Capability to update parameters such as trip setpoints or tunable parameters.

1. The parameter values to be updated are limited by the software application to pre-determined ranges.

Process Protection System Revision: 9 Interface Requirements Specification Page 72 of 78 2. The Maintenance Workstation software application shall request confirmation that the parameter update process is complete prior to saving the new tuning constant.6.

1. ALS bypass and test functions shall be accomplished through the ASU application implemented in the ALS MWS as discussed in Section 2.7.2.2. Placing a specific channel in bypass from the ASU shall not affect the safety function of other channels in the same ALS chassis that are not subject to the same bypass.3. Placing an individual channel in bypass in one ALS chassis (e.g., Chassis "A")from the ASU does not affect the safety function of any channels in the diverse ALS chassis (e.g., Chassis "B) in the same protection set.4. It shall be possible to place multiple channels in bypass concurrently within an ALS chassis. However, placing multiple channels in bypass shall require individual bypass actions for each channel. It shall not be possible to place multiple channels in bypass by a single action from the ASU.5. The Test ALS Bus (TAB) must be physically connected to the MWS as shown in Figure 2-7 to allow two-way communications on the TAB between the ALS chassis and the MWS.6. The ALS-A and ALS-B chassis partial trip outputs are connected to the SSPS input relays through an LSM that allows either ALS chassis to initiate a trip or actuation without affecting the ability of the other ALS chassis to initiate a trip or actuation

[Section 2.1.4, Figure 2-5, and Figure 2-6].7. The LSM shall not allow an ALS chassis to prevent the diverse ALS chassis from initiating a required trip or actuation.

8. Bypass switches on partial trip outputs, which allow removal of an ALS circuit board without initiating a false trip or actuation, will be provided by PG&E per FRS 3.2.1.3.5, 3.2.1,.3.6, and 3.2.1.5.3.

9. Trip switches on partial trip and actuation outputs, which allow a channel to be tripped manually, will be provided by PG&E per FRS 3.2.1.3.4.

10. Deleted.11. For deenergize to trip outputs, the PPS Failure contact closure due to bistable output failure to trip upon demand discrepancy shall be suppressed if a bypass is asserted from the ASU or from the manual bypass switch.12. Deleted 13. Deleted 14. The ASU shall be capable of storing 7 days of recent alarm log history. Oldest data shall be overwritten.

15. The ASU shall be capable of receiving data from both ALS Chassis A and ALS Chassis B concurrently.

16. PG&E will provide adm inistrative controls to prevent enabling the TAB on both ALS Chassis A and ALS Chassis B concurrently.

Process Protection System Interface Requirements Specification Revision: 9 Page 15 of 78.1 Introduction 1.1 1.2 1.3 1.3.1 Purpose This document specifies the requirements imposed on the Process Protection System (PPS), its subsystems, and other system components to achieve interfaces among these entities that are required for the PPS to perform its design function.This document is intended to be revised as the PPS replacement design progresses. Scope The PPS comprises Tricon equipment provided by Invensys/Triconex and Advanced Logic System (ALS) equipment provided by Westinghouse, LLC. This Interface Requirement Specification (IRS) provides: (1) requirements for the interfaces between external field devices such as process transmitters and the Tricon and the ALS; (2) electrical and communication interfaces between the Tricon and ALS and their associated peripheral devices; and (3) other interfacing Diablo Canyon Power Plant (DCPP) systems such as the Solid State Protection System (SSPS), Plant Process Computer (PPC), Main Annunciator System (MAS), Safety Parameter Display System (SPDS) and the Safety-Related 120 Vac and 125 Vdc Power Systems.All external interface requirements for each of these systems will be defined.Definitions and Acronyms Definitions The following definitions are used in this document: TERM DEFINITION Channel An arrangement of components, modules, and software as required to generate a single protective action signal when required by a generating station condition. A channel loses its_________________identity where single action signals are combined.Defeat Place a channel or function in an as-is condition. Electrical Class 1E Design Class I electrical systems, components and equipment[1.4.4.9] perform safety-related functions. Instrument Class IA and lB Category 1 devices below are considered to serve Class 1 E functions. All other instrument classes are considered to serve non-Class 1 E functions. Instrument Class IA Instrument Class IA instruments and controls are those that[1 .4.4.6] initiate and maintain safe shutdown of the reactor, mitigate the consequences of an accident, or prevent exceeding 10 CFR____ ___ ____ ___ 100 [1.4.5.2] off-site dose limits.Instrument Class lB Instrument Class lB instruments and c~ontrols are those th~at[1.4.4.6] -are required for post-accident monitoring of Category 1 and 2 variables in accordance with Regulatory Guide 1.97, Revision 3 [1.4.3.2]. Instrument Class IC Instrument Class IC instruments and controls have the[1.4.4.6] passive function of maintaining the pressure boundary integrity of PG&E Design Class I piping systems.Instrument Class ID Instrument Class ID instruments and controls are components [1:4.4.6] that have certain Design Class I attributes, but do not require conformance with all Class IA, IB, or IC requirements. Process Protection System Interface Requirements Specification Revision: 9 Page 16 of 78 TERM DEFINITION. .... .Instrument Class II Instrument Class II components are Design Class II devices[1.4.4.6] with non-safety-related functions. However, certain Class II components are subjected to some graded quality assurance requirements. May A termh used to denote permission to perform activities and is neither a requirement nor a recommendation. Out of Service An intentional inoperable condition established for a protection channel that prevents an unexpected interaction with other plant systems during maintenance activities. For protection system channels that include comparator outputs, the OOS condition is established when a comparator output from the PPS instrumentation is forced to a fixed state by plant personnel via the MWS.For the purpose of this definition, manual trip and manual bypass switches are external components and are not considered part of the PPS instrumentation. Partial Trip A condition where the SSPS input relay is in the tripped/actuated state.*For a Deenergize to Trip system output, the input relay state is False (0)* For an Energize to Trip system output, the input relay state is True (1)Protection Set The physical grouping of process channels with the same channel designation. Each of the four redundant protection sets is provided with a separate and independent power feed and process instrumentation transmitters. Thus, each of the four redundant protection sets is physically and electrically _________________independent from the other sets.Shall A term used to denote a legally binding (i.e., contractual) _________________ requirement. Should A term used to denote recommendations that are desirable, but not contractual requirements. Test in Bypass A maintenance condition in which the system output is maintained in the non-actuated condition.

For a Deenergize to Trip system output, the output is maintained in a True (1) state* For an Energize to Trip system output, the output is_________________

maintained in a False (0) state Test in Trip A maintenance condition in which the system output is maintained in the actuated condition.

For a Dee~nergi~z to Trip svs~tem output, the. output is maintained in a False (0) state a For an Energize to Trip system output, the output is______________

I maintained in a True (1) state Will A term used to denote intention or certainty; not a legally_________________binding (i.e., not contractual) requirement.

Process Protection System Revision: 9 Interface Requirements Specification Page 20 of 78 1.5.1 Protection Sets The PPS consists of sixteen (16) racks (per DCPP Unit) of instrumentation located in the Cable Spreading Rooms (Auxiliary Building, elevation 128). The sixteen racks are divided into four Protection Sets; five racks each for Protection Sets I and II, three racks each for Protection Sets ill and IV. Each Protection Set is physically separated and electrically isolated from the other sets.Protection Set I consists of Racks 1 thru 5 (RNP1A, RNP1B, RNP1C, RNP1D, and RNP1E). Set II consists of Racks 6 thru 10 (RNP2A, RNP2B, RNP2C, RNP2D, and RNP2E).Protection Set III consists of Racks 11 thru 13 (RNP3A, RNP3B, and RNP3C).Protection Set IV consists ofRacks 14 thru 16 (RNP4A, RNP4B, and RNP4C).Physical equipment will be assigned to specific PPS racks during detailed design.The existing Eagle 21 HMI units are located in Racks 5 (RNP1E), 9 (RNP2D), 12 (RNP3B) and 14 (RNP4A). These racks are expected to house the replacement PPS Maintenance Workstation and communications equipment. 1.5.2 Triconex Tricon Programmable Logic Controllers (PLC)The Tricon PLC shown in the following figures is composed of the Main Chassis and two Remote Expansion Chassis (RXMs), all within a given protection set. The Main Chassis is connected to a "Primary" RXM via triplicated copper I/O expansion bus cables. The Primary RXM (PRXM) is connected to a "Remote" RXM chassis using multimode fiber-optic cables. The Remote RXM (RRXM) chassis allows extending the I/O bus over longer distances than copper cables can support, and to provide electrical isolation for non-safety-related I/O signals, as required.Refer to the Triconex licensing Topical Report [1.4.5.3] for additional information. 1.5.3 Westinghouse Advanced LogicSystem (ALS)1.5.3.1 A typical ALS rack configuration as shown in the following figures contains two sets of the following components (See Reference 1.4.5.5 for additional details): ALS-1 02 -Core Logic Board (CLB)ALS-302 -Digital Input Board ALS-31 1 -Analog Input Board (Temperature) ALS-321 -Analog Input Board ALS-402 -Digital Output Board ALS-421 -Analog Output Board 1.5.3.2 ALS Service Unit (ASU)Th ASU is a dedicatedsoftware application that is-installed on tlhe-ALS Maintenance Workstation (MWS) described in Section 1.5.6 and shown in Figure 1-22. The ASU application is connected to the ALS during maintenance or testing by plant personnel. The ASU application provides non-intrusive diagnostic tools that allow plant personnel to access detailed status and configuration information of the system while the system is online.The ASU application also provides post-event analysis information about the system to plant personnel for evaluation of an event after it has occurred.The ASU application may be used to modify setpoints and tuning constants, but shall not be capable of altering functional programming (i.e., alter the Process Protection System Interface Requirements Specification Revision: 9 Page 21 of 78 algorithm) of the CLB.1.5.3.3 The ALS A and ALS B Conceptual architecture, which provides built-in diversity and defense in depth per the D3 evaluation approved by NRC[1.4.5.4], is illustrated in Figure 1-1. Wiring details are illustrated In Figure 2-5 and Figure 2-6.The manual bypass switches in Figure 1-1 allow one ALS diversity Group (i.e., ALS-A or ALS-B) to be bypassed and removed from service without tripping the channel. The manual trip switch may be used to initiate a partial channel trip independently of the ALS logic.Figure 1-1 ALS Diversity Architecture Concept De-energize to Trip Configuration Energize to Trip Configuration Note: Manual Trip switch as required by detailed design 1.5.4 Isolation Devices 1.5.4.1 The isolation devices shown in Figure 1-3, Figure 1-8, Figure 1-13, and Figure1-18are safety-related components providedby Westinghouse... 1.5.4.2 The isolation devices are separate and independent from both the Tricon and the ALS.1.5.4.3 All isolation devices are 4-20 mA DC input and 4-20 mA DC output.1.5.4.4 The qualified isolation devices shall perform the required isolation function when powered from non-safety-related I/O power. That is, credible faults (short circuit, open circuit, application of fault potential) on the Class II terminals will not adversely affect the Class I circuit. Process Protection System Revision: 9 Interface Requirements Specification Page 22 of 78 1.5.5 ALS Signal Conditioning 1.5.5.1 The ALS shall provide signal conditioning and isolation for the Reactor Coolant System (RCS) non-safety-related flow analog output signals 1.5.5.2 The ALS shall provide capability to normalize the RCS Flow scaling periodically by adjusting the gain and offset (i.e., mex+b) from within the ALS application via the ASU.1.5.5.3 The ALS shall provide signal conditioning for the RCS narrow range Resistance Temperature Detector (RTD) safety-related signals to the Overpower Delta Temperature (OPDT) and Overtemperature Delta T (OTDT) reactor trip functions, and the RCS Wide Range Temperature and Pressurizer Vapor Space Temperature RTD signals.1. The ALS shall convert the RTD signals from resistance to temperature.

2. The ALS shall provide the capability to update the resistance to temperature conversion coefficients (i.e., a, b, and c) periodically.

3. Analog temperature signal input range information is provided in the following FRS Sections: a) 3.2.3.9 (WR Hot Leg and Cold Leg Temperatures), b) 3.2.5.9 (Tavg, AT, OPDT Setpoint, OTDT Setpoint), and c) 3.2.8.9 (PZR Vapor Temp).1.5.5.4 Temperatures shall be transmitted from the ALS to the Tricon via safety-related 4-20 mA analog signals scaled as follows: 1. Narrow Range Tcold: 510 -630 deg F [FRS 3.2.5.9.1]

2. Narrow Range Thot: 530- 650 deg F [FRS 3.2.5.9.1]

3. Wide Range Thot: 0 to 700 0 F [FRS 3.2.3.9.3.a]

4. Wide Range Tcold: 0 to 700 0 F [FRS 3.2.9.3.b]

5. Pressurizer Vapor Temperature:

100 to 700 0 F [ERS 3.2.8.9.3.a]

6. The Tricon shall provide an mx+b filter on the 4-20 mA input signals per FRS 3.2.1.14.3.

1.5.5.5 If the actual temperature is below the low scale output value defined in Section 1.5.5.4 the ALS shall output the low scale value, or 0% of span=4.00 mA without initiating an Out of Range Low alarm.1.5.5.6 The ALS shall provide down-scale open RTD protection; that is, if the ALS detects an open or shorted RTD, it shall output a 0.0 mA analog signal.1.5.5.7 All temperatures shall be transmitted from the ALS to the Gateway computer via RS-422 signals scaled for the qualified range of the RTD input board.1_5.5_8. This-aiiows the-Tricon to-provide RTD-faiiure aiarming-and-ensures that the , Tricon does not indicate RTD failure when the temperature is below low scale but still functioning correctly, a condition that exists during plant shutdown 1'.5.5.9 In the latter case, the actual temperature is available from the ALS via the Gateway computer via the TxB1 data stream.1.5.5.10 Analog output signals shall fail low, if possible, upon detection of critical failure. Process Protection System Revision: 9 Interface Requirements Specification Page 23 of 78 1.5.6 Maintenance Workstation 1.5.6.1 Separate and independent Maintenance Workstation computers [Section 2.7]shown in Figure 1-22 are provided for the Tricon and ALS subsystems, respectively, for each Protection Set to allow PPS informatiOn processing and display. The two MWS computers in each Protection Set share common HMI peripheral devices such as the keyboard, video display, mouse (KVM), and touchscreen interface through a KVM switch [Section 2.3.7].1.5.6.2 The Tricon will be isolated from its dedicated Maintenance Workstation computer by the qualified safety-related Triconex Communications Module (TOM). Fiber optic cable electrically isolates the Tricon from external non-safety-related devices.1.5.6.3 The ALS broadcasts data to its dedicated Maintenance Workstation computer via the isolated one-way TxB2 RS-422 data links. TAB communications between the ALS and the MWS takes place via RS-485 data link. The TAB is physically disconnected from the MWS when the TAB is not in use. The TAB is connected and enabled only when maintenance is being performed on the ALS. It is disconnected at all other times. The TAB is enabled for short periods only when ALS maintenance is being performed, and maintenance will be performed under administrative controls by qualified individuals. This arrangement satisfies NRC DI&C ISG-04, Staff Position 10 of Section 1, Interdivisional Communications [1.4.3.4]. 1.5.6.4 A Maintenance' Workstation computer may access data only within its own protection set subsystem (i.e., Tricon or ALS). Communication with other protection sets or between subsystems within a Protection Set shall not be possible.1.5.7 Plant Process Computer Gateway and Other Non-,Safety-Related Communications Interfaces 1.5.7.1 The safety-related Tricon and ALS are connected to the non-safety-related PPC and workstation via the Gateway computer shown in Figure 1-22. The Gateway computer will be installed by PG&E in the Process Control `system (PCS) replacement project. The ALS-1 02 CLB provides isolation for the TxB1 and TxB2 one-way EIA-422 communication links to the PPC Gateway and the Maintenance Workstation, respectively. The ALS transmits data to the non-safety-related Gateway computer, which is common to all four protection sets, and to the Maintenance Workstation using serial, unidirectional, one-way communications channels that do not require any handshaking. 1.5.7.2 The Tricon will be isolated from the Gateway computer by a data isolation device such as the port aggregator network tap shown in Figure 1-22, which permits two-way communications between the Maintenance Workstation belonging to a specific protection set and the Tricon in that protection set, yetvy ev n I--U- L V %.c4L.VVay I IjJULL .:I I IE port aggregator tap will be provided by PG&E.1.5.7.3 For system health displays, the PPS will share a HMI unit in the Control Room on CC4 that will also be installed by the Process Control System (PCS) replacement project.1.5.8 Response Time The reactor trip response time is the time interval from when the monitored parameter exceeds its trip setpoint at the channel sensor, until loss of control rod Process Protection System Revision: 9 Interface Requirements Specification Page 24 of 78 stationary gripper coil voltage. The ESF response time is the time interval from when the monitored parameter exceeds its trip setpoint until the ESF equipment is capable of performing its safety function. The PPS is allocated a maximum response time of 0.409 seconds [1 .4.4.8].1.5.8.1 The ALS performs signal conditioning for the narrow range RTD's that support the Overtemperature AT (OTOT) and Overpower AT (OPDT) reactor trips, and the Tricon performs setpoint calculation and comparison and trip output. Therefore, the PPS time response allocation is shared between the ALS and Tricon portions of the PPS for these functions. 1.5.8.2 The preliminary worst case (deterministic) OTDT and OPDT PPS response time allocations shall be as follows: ALS: "0.175 seconds for RTD processing Tricon: 0.200 seconds Contingency: 0.034 seconds Total PPS Allocation: 0.409 seconds 1.5.8.3 The vendor shall provide means of verifying the actual response time if the system does not support deterministic methods of calculating worst case response time characteristics. 1.5.9 Accuracy The FRS specifies existing Eagle 21 accuracy requirements with the intent to maintain currently licensed Channel Statistical Allowance (CSA) margins such that no setpoint changes are required. Accuracy allocation between the ALS and Tricon for the RCS temperature parameters will be determined during the detailed design.

The I/O list contains the following information for each protection set. As noted below, some I/O list information is outside the scope of this interface specification. 2.1.1 I/O Power Supplies 1. Separate power supplies will be provided by PG&E for Triconex analog and digital I/O per the Triconex qualification.

2. All Tricon discrete inputs and outputs will be powered by PG&E in accordance with the requirements provided in the l/O list.3. All ALS discrete inputs and outputs will be wetted by 48 Vdc supplied by PG&E.4. The Pressurizer pressure channels are shared among the ALS, Tricon, and the control system, via qualified isolator modules, and will be powered by the Tricon ETP as shown in Figure 2-3.5. Deleted 6. All 4-20 mA analog input signals are powered from power supplies located within the PPS cabinets.

The 0-10 VDC analog signals from the Nuclear Instrumentation System (NIS) are powered by the NIS.7. PG&E will provide analog loop power supplies. Analog input loop power supply voltage should not exceed 40 Vdc, and may be as low as 24 Vdc based on the following considerations and assumptions:

a. Rosemount 1154 and 1154 Series H 1) Max qualified power supply voltage: 45 Vdc 2) Max Design loop resistance at 45 Vdc input: 1575 ohms 3) Mmn Design loop resistance at 45 Vdc input: 500 ohms 4) Max Design loop resistance at 24 Vdc input: Approx. 700 Ohms 5) Min Design loop resistance at 24 Vdc input: 0 Ohms b. Rosemount 1153 Series B&D Output Code P 1) Max qualified power supply voltage: 40 Vdc 2) Max Design loop resistance at 40 Vdc input: 1325 ohms 3) Mmn Design loop resistance at 40 Vdc input: 500 ohms 4) Max Design loop resistance at 24 Vdc input: Approx. 600 Ohms 5) Min Design loop resistance at 24 Vdc input: 0 Ohms c. Rosemount 1153 Series B&D Output Code R 1) Max qualified power supply voltage: 45 Vdc 2) Max Design loop resistance at 45 Vdc input: 1575 ohms 3) Min Design loop resistance at 45 Vdc input: 500 Ohms Process Protection System Revision:

Barton 763 max power supply voltage: 50 Vdc e. Barton 763 Max loop resistance at 40 Vdc input: Approx. 1250'ohms f. Barton 763 Mmn loop resistance at 40 Vdc input: Approx. 190 ohms g. Triconex 3805N Analog Output module OVP: 42.5 Vdc h. ALS input resistance is 200 ohms [Figure 2-2] with both "A" and "B" 302 connected in series (i.e., Rs = 100 ohms).i.Triconex 9792-610N Reg. Guide 1.180 FTP Approx. input resistance:

1) When powered from the FTP (max 48 Vdc supply): (250 + 1/(1/250 +1/3300)) = 482 ohms ~500 ohms)2) When externally powered: 250 ohms (i.e., temperature signals from the ALS)j. Resistances of external loop devices are (PG&E scope): 1) Isolator input 4-20 mA into 100 ohms (estimated)

2) Westinghouse VX-252 indicator:

5 ohms (including estimated wire resistance)

3) ERFDS: Loop-Specific (Usually 250 ohms or 50 ohms)4) RVLIS: 250 ohms k. ALS 4-20 mA analog outputs are powered by the ALS. Therefore,-

temperature inputs to the Tricon shall not use the Positive Temperature Coefficient (PTC) thermistor for loop overcurrent protection and the input resistance for Tricon temperature inputs is 250 ohms.8. Tricon Analog Output Power Supply a. Analog outputs in the safety-related Triconex Main Chassis will be powered by redundant 24 Vdc power supplies furnished by PG&E.b. Analog outputs in the non-safety related Triconex Remote RXM chassis will be powered by redundant24 Vdc power supplies furnished by PG&E and mounted in the rack housing the RRXM chassis.c. Deleted.2.1.2 Analog Inputs Figure 2-2, Figure 2-3, and Figure 2-4 illustrate typical PPS analog input signal wiring[1.4.5.6, 1.4.5.7]: 1. PT-455 signal shared among Tricon (DTT-IA functions), ALSA, ALS-B and an isolation device 2. LT-459 Signal shared among Tricon, ControBad ad an device 3. PT-5OS signal shared among the Tricon, and an isolation device 4. RCS Temperature signals are conditioned by ALS-A and ALS-B, respectively before they are input to the Tricon. Example wiring for these signals is shown in Figure 2-3.5. Tricon Al card type 3721N shall be configured for 14-bit resolution, unipolar.These cards are used for all 4-20 mA analog inputs to the PPS*6. Tricon Al cards 3703E (where used) and 3703EN shall be selected for 0-10 Vdc input, fail downscale. These cards are used for Nuclear Instrumentation (NI)inputs to the PPS. Process Protection System Revision: 9 Interface Requirements Specification Page 52 of 78 7. Signals from redundant field devices shall be processed on separate input boards (Not applicable to ALS).2.1.3 Discrete Inputs Signals from redundant field devices shall be processed on separate input boards (Not applicable to ALS).2.1.4 Discrete Outputs Figure 2-5 and Figure 2-6 illustrate typical ALS discrete output signal wiring that implements the diversity architecture [Figure 1-1] using a Line Sense Module (LSM)to provide a hardwired OR configuration between Diversity Groups ALS-A and ALS-B and to enable the ALS to perform continuous error checks.Upon detecting the following conditions, noted actions shall be taken: 1. Failure to Trip on Demand Close ALS Failure contact 2. Trip without Demand Close ALS Trouble contact The LSM is illustrated in Figure 2-1. Configuration of the LSM for use in an Energize to Trip (ETT) or Deenergize to Trip (DTiT) circuit is done through field wiring terminations on the LSM and does not require any modification of any electrical properties of the LSM itself. Thus, a single LSM can be used in an ETT or DTT circuit without the need to electrically configure the module for the trip circuit type before use.
