1.5 Identification

This section identifies the systems, interfacing entities, and other interfaces to which thisdocument applies.

1.5.1 Protection Sets

The PPS consists of sixteen (16) racks (per DCPP Unit) of instrumentation located in theCable Spreading Rooms (Auxiliary Building, elevation 128). The sixteen racks aredivided into four Protection Sets; five racks each for Protection Sets I and II, three rackseach for Protection Sets III and IV. Each Protection Set is. physically separated andelectrically isolated from the other sets. Figure 1-1 illustrates the hardware thatcomprises the sixteen (16) protection sets.Protection Set I is comprised of Racks 1 thru 5 (RNP1A, RNP1B, RNP1C, RNP1D, andRNP1E).Protection Set II is comprised of Racks 6 thru 10 (RNP2A, RNP2B, RNP2C, RNP2D, andRNP2E).Protection Set III is comprised of Racks 11 thru 13 (RNP3A, RNP3B, and RNP3C).

Protection Set IV is comprised of Racks 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 PPSMaintenance Workstation and communications equipment.

1.5.2 Triconex Tricon Programmable Logic Controllers (PLC)

The Tricon PLC shown in the following figures comprises the Main Chassis and twoRemote Expansion Chassis (RXMs), all within a given protection set. The Main Chassisis connected to a "Primary" RXM via triplicated copper I/O expansion bus cables. ThePrimary 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 overlonger distances than copper cables can support, and to provide electrical isolation fornon-safety-related I/O signals, as required.Refer to the Triconex licensing Topical Report [1.4.5.3] for additional information.

1.5.3 CS Innovations Advanced Logic System (ALS)

1.5.3.1 A typical ALS rack configuration as shown in the following figures containstwo sets of the following components (See Reference 1.4.5.5 for additionaldetails):

ALS CLB - Core Logic Board

ALS IPB - Input BoardALS OPB - Output Board

ALS PSU - Power Supply Unit

1.5.3.2 ALS ASU -Auxiliary Service Unit

The ASU shown in Figure 1-22 is a dedicated piece of test equipment which can be



connected to the ALS rack during diagnostics or testing by plant personnel. The ASUprovides non-intrusive diagnostic tools that allow plant personnel to access detailedstatus and configuration information of the system while the system is online. TheASU also provides post-event analysis information about the system to plantpersonnel for evaluation of an event after it has occurred.The ASU can modify setpoints and tuning constants, but cannot alter functionalprogramming (i.e., alter the algorithm) of the CLB.

In the PPS Replacement project, the Maintenance Workstation will perform thefunctions of the ASU.

1.5.3.3 The ALS A and ALS B conceptual architecture to provide built-in diversityand defense in depth per the D3 evaluation approved by NRC [1.4.5.4] isillustrated in Figure 1-1. Wiring details are illustrated In Figure 2-5 andFigure 2-6.

The manual bypass switches in Figure 1-1 allow one ALS diversity Group (i.e., ALS-Aor 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 ofthe ALS logic.

.1.5.4 Isolation Devices

The isolation devices shown in Figure 1-3, Figure 1-8, Figure 1-13, and Figure 1-18 aresafety-related components powered from the Class II 24 Vdc I/O power supplies providedby PG&E. The isolation devices are separate and independent from both the Tricon andthe ALS. All isolation devices are 4-20 mA DC input and 4-20 mA DC output. Input andoutput range information is provided in the I/O List [Appendix 3.1]. The qualified isolationdevices perform the required isolation function when powered from non-safety-related I/Opower. That is, credible faults (short circuit, open circuit, application of fault potential) onthe Class II terminals will not adversely affect the Class I circuit.


1.5.5 ALS Signal Conditioning

1.5.5.1 The ALS shall provide signal conditioning and isolation for the ReactorCoolant System (RCS) non-safety-related flow analog output signals withcapability to normalize the scaling periodically.

1.5.5.2 The ALS shall provide signal conditioning for the RCS narrow rangeResistance Temperature Detector (RTD) safety-related signals to theOverpower Delta Temperature (OPDT) and Overtemperature Delta T (OTDT)reactor trip functions, and for the RCS Wide Range Temperature andPressurizer Vapor Space Temperature RTD signals.

1.5.5.3 The ALS shall convert the RTD signals from resistance to temperature. TheALS shall provide capability to update the resistance to temperatureconversion coefficients periodically. Analog temperature signal input andoutput range information is provided in the I/O List [Appendix 3.1]

1.5.5.4 Temperatures shall be transmitted from the ALS to the Tricon via 4-20 mAanalog signals scaled per Appendix 3.1.

1.5.5.5 All temperatures shall be transmitted from the ALS to the Gateway computervia RS-422 signals scaled for the full input range per Appendix 3.1.

1.5.5.6 The ALS .shall provide down-scale open RTD protection. If the ALS detectsan open or failed RTD, it shall output an analog signal below the Triconsignal failure threshold, which is -5% of span = 3.20 mA per the FRS [6]. Ifthe actual temperature is below the low scale value provided in Appendix 3.1,the ALS shall output the low scale value, or 0% of span = 4.00 mA. Thisallows the Tricon to provide RTD failure alarming and ensures that the Tricondoes not indicate RTD failure when the temperature is below low scale butstill functioning correctly, a condition that exists during plant shutdown. In thelatter case, the actual temperature shall be available from the ALS via the.Gateway computer.

1.5.6 Maintenance Workstation

Separate and independent Maintenance Workstation computers [Section 2.7] showninFigure 1-22 are provided for the Tricon and ALS subsystems, respectively, for eachProtection Set to allow PPS information processing and display. The two MWScomputers in each Protection Set share common HMI peripheral devices such as thekeyboard, video display, mouse (KVM), and touchscreen interface through a KVM switch[Section 2.3.7].

The Tricon will be isolated from its dedicated Maintenance Workstation computer by thequalified safety-related Triconex Communications Module (TCM). Fiber optic cableelectrically isolates the Tricon from external non-safety-related devices.

The ALS broadcasts data to its dedicated Maintenance Workstation computer via theisolated one-way TxB2 RS-422 data links. TAB communications between the ALS andthe MWS take place via RS-485 data link. The TAB is physically disconnected from theMWS when the TAB is not in use. The TAB is connected and enabled only whenmaintenance is being performed on the ALS. It is disconnected at all other times. TheTAB is enabled for short periods only when ALS maintenance is being performed, andmaintenance 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].

A Maintenance Workstation computer may access data only within its own protection setsubsystem (i.e., Tricon or ALS). Communication with other protection sets or betweensubsystems within a Protection Set is not possible.


1.5.7 Plant Process Computer Gateway and Other Non-Safety-Related CommunicationsInterfaces

The safety-related Tricon and ALS are connected to the non-safety-related PPC andworkstation via the Gateway computer shown in Figure 1-22. The Gateway computer willbe installed by PG&E in the Process Control System (PCS) replacement project. TheALS Core Logic Board (CLB) provides isolation for the TxB1 and TxB2 one-way EIA-422communication links to the PPC Gateway and the Maintenance Workstation,respectively. The ALS transmits data to the non-safety-related Gateway computer, whichis common to all four protection sets, and to the Maintenance Workstation using serial,unidirectional, one-way communications channels that do not require any handshaking.

The Tricon will be isolated from the Gateway computer by a data isolation device such asthe port aggregator network tap shown in Figure 1-22, which permits two-waycommunications between the Maintenance Workstation belonging to a specific protectionset and the Tricon in that protection set, yet allows only one-way communication to thePPC Gateway Computer. The port aggregator tap will be provided by PG&E.

For system health displays, the PPS will share a HMI unit in the Control Room on CC4that 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 parameterexceeds its trip setpoint at the channel sensor, until loss of control rod stationary grippercoil voltage. The ESF response time is the time interval from when the monitoredparameter exceeds its trip setpoint until the ESF equipment is capable of performing itssafety function. The PPS is allocated a maximum response time of 409 ms [1.4.4.8].The ALS performs signal conditioning for the narrow range RTD's that support theOvertemperature AT (OTDT) and Overpower AT (OPDT) reactor trips, and the Triconperforms setpoint calculation and comparison and trip output. Therefore, the PPS timeresponse allocation is shared between the ALS and Tricon portions of the PPS for thesefunctions.The preliminary worst case (deterministic) OTDT and OPDT PPS response timeallocations are as follows:ALS: 175 ms for RTD processing

Tricon: 200 ms

Contingency: 34 msTotal PPS Allocation: 409 ms

The vendor shall provide means of verifying the actual response time if the system doesnot support deterministic methods of calculating worst case response timecharacteristics.

1.5.9 Accuracy

The FRS specifies existing Eagle 21 accuracy requirements with the intent to maintaincurrently licensed Channel Statistical Allowance (CSA) margins such that no setpointchanges are required. Accuracy allocation between the ALS and Tricon for the RCStemperature parameters will be determined during the detailed design.

2 Interface RequirementsThis section specifies the requirements imposed on the systems, subsystems, configurationitems, or other system components to achieve required interfaces among these entities.

2.1 Process Interface Requirements

Appendix 3.1 describes process inputs and outputs for the PPS replacement project.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

The Triconex qualification requires that separate power supplies be used for analog anddigital i/o.

1. All Tricon discrete inputs and outputs will be powered in accordance with therequirements provided in the I/O list.

2. The Containment Pressure Bypass switch inputs to the ALS will be dry contactswetted by 48 Vdc supplied by PG&E.

3. The Pressurizer pressure loops are shared among the ALS, Tricon, and the controlsystem, via qualified isolator modules, and will be powered by the Tricon ETP asshown in Figure 2-3.

4. Where the analog input signal source is a process transmitter, bounding loopresistances per the I/O list are as follows:

a. Max resistance < 750 ohms

b. Min resistance > 200 ohms5. All 4-20 mA analog 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.

6. PG&E will provide power supplies which will accommodate the above bounding loopresistance values. Analog input loop power supply voltage should not exceed 40Vdc, and may be as low as 24 Vdc based on the following considerations andassumptions:

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) Min 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



3) Min Design loop resistance at 40 Vdc input: 500 ohms

4) Max Design loop resistance at 24 Vdc input: Approx. 600 Ohms



c. Rosemount 1153 Series B&D Output Code R




4) Max Design Loop Resistance at 24 Vdc input: Approx. 700 ohms

5) Min Design Loop Resistance at 24 Vdc input: 0 ohms

d. Barton 763 max power supply voltage: 50 Vdc

e. Barton 763 Max loop resistance at 40 Vdc input: Approx. 1250 ohmsf. Barton 763 Min loop resistance at 40 Vdc input: Approx. 190 ohms

g. Triconex 3805N Analog Output module OVP: 42.5 Vdc

h. ALS input resistance is 220 ohms [Figure 2-4] when both "A" and "B" 302boards are in the circuit.

i. Triconex 9792-61 ON Reg. Guide 1.180 FTP Max 48 Vdc (Approx. inputresistance: (250 + 1/(1/250 + 1/3300)) - 482 ohms)

j. Input and output loop resistances as shown in Appendix 3.1 based onTriconex resistance above and:

* Isolator input 4-20 mA into 20 ohms (estimated)

" Westinghouse VX-252 indicator: 5 ohms (including estimated wireresistance)

* ERFDS: 50 ohms

" RVLIS: 250 ohms

k. ALS 4-20 mA analog outputs are powered by the ALS. Therefore,temperature inputs to the Tricon will not use the Positive TemperatureCoefficient (PTC) thermistor for loop overcurrent protection and the inputresistance for Tricon temperature inputs is 250 ohms.

7. Tricon Analog Output Power Supply

a. Analog outputs in the safety-related Triconex Main Chassis will be poweredby redundant 24 Vdc power supplies furnished by PG&E.

b. Analog outputs in the non-safety related Triconex Remote RXM chassis willbe powered by redundant 24 Vdc power supplies furnished by PG&E andmounted in the rack housing the RRXM chassis.

c. The Tricon analog output power supply shall not be shared with any discreteinput or output signals.

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 (DTTA functions), ALS-A, ALS-B and anisolation device

2. LT-459 signal shared among Tricon, Control Board indicators and an isolation device

3. PT-505 signal shared among the Tricon, and an isolation device

4. RCS Temperature signals are conditioned by ALS-A and ALS-B, respectively beforethey are input to the Tricon. Example wiring for these signals is shown in Figure 2-3.

5. Tricon Al cards 3721 (where used) and 3721N shall be configured for 14-bitresolution, 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 Vdcinput, fail downscale. These cards are used for Nuclear Instrumentation (NI) inputsto the PPS.

7. Signals from redundant field devices shall be processed on separate input boards.

2.1.3 Discrete Inputs

Signals from redundant field devices shall be processed on separate input boards.

2.1.4 Discrete Outputs

Figure 2-5 and Figure 2-6 illustrate typical ALS discrete output signal wiring thatimplements the diversity architecture [Figure 1-1] using a Line Sense Module (LSM) toprovide a hardwired OR configuration between Diversity Groups ALS-A and ALS-B andto enable the ALS to perform continuous error checks for detecting the followingconditions:

* Failure to Trip on Demand

• Trip without Demand

" Failure to Bypass

* Illegal Bypass

The LSM is illustrated in Figure 2-1. Configuration of the LSM for use in an Energize toTrip (ETT) or Deenergize to Trip (DTT) circuit is done through field wiring terminations onthe LSM and does not require any modification of any electrical properties of the LSMitself. Thus, a single LSM can be used in an ETT or DTT circuit without the need toelectrically configure the module for the trip circuit type before use. This allows a singlepart number to be used to provide spares for both ETT and DI7 circuit configurations.

Refer to the ALS Design Specification [1.4.5.6] for additional information regarding theLSM and field wiring interface.

Without these function blocks programmed into the applicationprogram application program parameters cannot be modified with the keyswitch in theRUN position. The Tricon protection set is considered inoperable when the keyswitch isnot in RUN position.

The HMI application in the ALS MWS computers shall interface (1-way) with the ALS viathe isolated TxB2 RS-422 data link. The two MWS computers in each Protection Setshare peripheral devices through a KVM switch. Refer to Section 2.3.7 for details.

2.7.2 Auxiliary Service Unit Application Software

Software application shall be provided by Vendor CS Innovations to run on the ALSMaintenance Workstation Computers. The ASU application utilizes a two-way RS-485communication link to communicate with the Test ALS Bus (TAB) that is physicallydisconnected from the MWS computer when it is not in use. The activation of the TABvia connecting the TAB data link to the MWS computer does not interfere with the abilityof the ALS safety channels to perform their respective safety functions and the ALS is stilloperable during activation of the TAB. Therefore, individual instrument loops may beplaced is bypass for maintenance and the rest of the ALS safety channel is still operablewith respect to its safety function.

To detect the TAB connection, the ALS-1 02 DI #2 needs to be connected to ALS-1 02'lnput.Rtn as shown in Figure 2-7 [Reference 1.4.5.8, Figure 4-2].

2.8 Alarm Interface Requirements

The PPS shall provide the following alarm output signals from each Protection Set forconnection to the Main Annunciator System (MAS) in the DCPP Main Control Room(MCR). Separate input signals shall be provided for these alarms from each ProtectionSet per Section 3.2.1.5 of the FRS [1.4.4.2].

2.8.1 PPS Failure (Deenergize to Alarm with Reflash capability)

The conditions listed in FRS Section 3.2.1.5.1 shall provide signals to initiate the PPSFailure alarm in the Main Control Room.

2.8.2 PPS Trouble (Deenergize to Alarm with Reflash capability)

The following platform-specific inputs to the Main Control Room PPS Trouble Alarm shallbe provided in addition to those listed in FRS Section 3.2.1.5.2. Other alarms not listedhere or in the FRS may be provided to meet platform diagnostic requirements.

2.9.6.6 Tricon PPS Subsystem Specific Requirements

1. External trip switches will be provided on PPS partial trip and actuation outputsthat de-energize to trip. The switches may be used for SSPS input relay testingor to trip or actuate the channel manually if needed. External trip switches arenot required for energize to trip outputs.

0


2. On-line testing shall be controlled by the safety-related Tricon processor enabledvia a permissive from an external safety-related hardwired Out of Service (OOS)switch.

3. When the OOS switch is activated, the safety-related function processor shallallow the associated instrument channel to be taken out of service whilemaintaining the remainder of the Protection Set operable. Features to limitinadvertently placing a channel OOS shall include, but not be limited to:

a. Approved PG&E procedures are required to perform testing operations.

b. Operation of the hardware OOS switch alone shall not place the channel outof service.

c. More than one specific action shall be required at the MaintenanceWorkstation to perform the maintenance functions. In order to perform anytest operation from the maintenance workstation, the user must:

(1) Activate the OOS switch for the specific loop to be tested

(2) Log in as a maintenance user on the maintenance workstation

(3) Open the maintenance screen for the specific loop being tested

(a) On the maintenance screen, request the desired test mode(b) On the maintenance screen, confirm the requested test mode (Loop

.is placed OOS only after the requested mode is confirmed)

(c) If it is desired to change the test mode, repeat steps 3.(a) and 3.(b)while the channel is OOS; selecting a different test mode alone shallnot cause or require returning the channel to service.

(4) The channel shall return to service:

(a) When the OOS switch is returned to its normal position; or

(b) When so commanded from the MWS

d. Feedback is provided to the user on the maintenance workstation that thehardware OOS switch for the loop to be tested has been activated.

e. Continuous indication is provided in the control room that a loop is OOS.

f. If the safety-related hardware out of service switch is not activated, non-safety-related actions or failures cannot adversely affect the safety-relatedfunction.

g. An instrument loop is not permitted to be bypassed if external trip switch is inthe trip position. The user may test in trip in this condition following requestand confirmation as described above.

4. Maintenance modes allowable under 3.c.(3) above shall include:

a. Test in Bypass: The channel trip output is maintained in the untrippedcondition while in this mode; that is, Test in Bypass mode shall override theoutput of the channel trip comparator to prevent generation of a partial tripfrom the channel being tested.

b. Test in Trip: The channel trip output is maintained in the tripped conditionwhile in this mode; that is, Test in Trip mode shall override the output of thechannel trip comparator to initiate partial trip or actuation from the channelbeing tested.

c. Parameter Update: Capability to update parameters such as trip setpoints ortunable parameters.

(1) The parameter values to be updated are limited by the softwareapplication to pre-determined ranges.


(2) The Maintenance Workstation software application shall request operatorconfirmation that the parameter update process is complete prior to saving thenew tuning constant.

2.9.6.7 ALS PPS Subsystem Specific Requirements

1. ALS bypass and test functions are accomplished through ALS Service Unit(ASU) software implemented in the MWS as discussed in Section 2.7.2.

2. Placing a specific channel in maintenance bypass shall not affect the safetyfunction of other channels in the same ALS chassis that are not subject to thesame maintenance bypass.

3. Placing an individual channel in maintenance bypass in one ALS chassis (e.g.,Chassis "A") shall not affect the safety function of any channels in the diverseALS chassis (e.g., Chassis "B) in the same protection set.

4. Multiple channels may be placed in maintenance bypass concurrently within anALS chassis. However, placing multiple channels in maintenance bypass shallrequire individual bypass actions for each channel. Multiple channels shall notbe placed in maintenance bypass by a single action.

5. The Test ALS Bus (TAB) must be physically connected to the MWS as shown inFigure 2-7 to allow two-way communications on the TAB between the ALSchassis and the MWS.

6. The ALS-A and ALS-B chassis partial trip outputs are hardwire OR'd to the SSPSinput relays through an external LSM to allow either ALS chassis to initiate a tripor actuation. Refer to Figure 2-5 and Figure 2-6 for LSM usage.

7. The LSM shall not allow an ALS chassis to prevent the diverse ALS chassis frominitiating a required trip or actuation.

8. External bypass switches are provided for the individual ALS-A and ALS-B partialtrip outputs to allow removal of an ALS circuit board in without initiating a falsetrip or actuation.
