6 Page 3 of 47 1 1.1 1.2 1.3 1.3.1 Introduction 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 is comprised of Tricon equipment provided by Invensys/Triconex and Advanced Logic System (ALS) equipment provided by Westinghouse CS Innovations, 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 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 DEFIINIITION 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.Electrical Class 1E Design Class I electrical systems, components and equipment[1.4.4.9]

perform safety-related functions.

Instrument Class. IA and IB 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 IB Instrument Class lB instruments and controls are those that[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:

6 Page 4 of 47 1.3.2 TERM D.EFINITION 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.

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.Acronyms ACRONYM DEFINITION ALS Advanced Logic System AMSAC ATWS Mitigation System Actuation Circuitry ASU (ALS) Auxiliary Service Unit ATWS Anticipated Transient Without Scram CDD Conceptual Design Document CLB Core Logic Board COM Communications Board DCM Design Criteria Memorandum DDE Dynamic Data Exchange DCPP Diablo Canyon Power Plant DFWCS Digital Feedwater Control System FRS Functional Requirements Specification I&C Instrumentation and Controls IEEE Institute of Electrical and Electronic Engineers I/O Input/Output IPB (ALS) Input Board IRS Interface Requirements Specification LLC Limited Liability Corporation MAS Main Annunciator System MCR Main Control Room NQEL Nuclear Qualified Equipment List NR Narrow Range NRC (USNRC) (United States) Nuclear Regulatory Commission OPB (ALS) Output Board OPDT Overpower Delta T OTDT Overtemperature Delta T PG&E (PGE) Pacific Gas & Electric Company PCS Process Control System PLC Programmable Logic Controller PPC Plant Process Computer PPS Process Protection System PRXM Primary Remote Expansion Module PSU (ALS) Power Supply Unit RCS Reactor Cooling System RNARA Auxiliary Relay Rack A Process Protection System Interface Requirements Specification Revision:

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. Figure 1-1 illustrates the hardware that comprises the sixteen (16) protection sets.

Process Protection System Revision:

6 Interface Requirements Specification Page 7 of 47 Protection Set I is comprised of Racks 1 thru 5 (RNP1A, RNP1B, RNP1C, RNP1D, and RNP1 E).Protection Set II is comprised of Racks 6 thru 10 (RNP2A, RNP2B, RNP2C, RNP2D, and RNP2E).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 (RNP1 E), 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 comprises 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 CS Innovations Advanced Logic System (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 CLB -Core Logic Board ALS IPB -Input Board ALS 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 ASU 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 also provides post-event analysis information about the system to plant personnel for evaluation of an event after it has occurred.The ASU can modify setpoints and tuning constants, but cannot alter functional programming (i.e., alter the algorithm) of the CLB.In the PPS Replacement project, the Maintenance Workstation will perform the functions of the ASU.1.5.3.3 The ALS A and ALS B conceptual architecture to provide 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 2-4 and Figure 2-5.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.

Process Protection System 14 Interface Requirements Specification Revision:

6 Page 8 of 47 1.5.4 The manual trip switch is used to trip the channel in the unlikely event that both ALS diversity groups are inoperable.

Isolation Devices The isolation devices shown in Figure 1-3, Figure 1-8, Figure'1-13, and Figure 1-18 are safety-related components powered from the Class II 24 Vdc I/O power supplies provided by PG&E. The isolation devices are separate and independent from both the Tricon and the ALS. All isolation devices are 4-20 mA DC input and 4-20 mA DC output. Input and output range information is provided in the I/O List [Appendix 3.1]. The qualified isolation devices 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.Figure 1-1 ALS Diversity Architecture Concept De.energize to Trip Configuration Energize to Trp Configuration W Tnpa~mqdW by, O.W deM 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 with capability to normalize the scaling periodically.

1.5.5.2 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 for the RCS Wide Range Temperature and Pressurizer Vapor Space Temperature RTD signals.1.5.5.3 The ALS shall convert the RTD signals from resistance to temperature.

The ALS shall provide capability to update the resistance to temperature conversion coefficients periodically.

Analog temperature signal input and output 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 mA analog signals scaled per Appendix 3.1.

Process Protection System Revision:

6 Interface Requirements Specification Page 9 of 47 1.5.5.5 All temperatures shall be transmitted from the ALS to the Gateway computer via 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 detects an open or failed RTD, it shall output an analog signal below the Tricon signal failure threshold, which is -5% of span = 3.20 mA per the FRS [6]. If the 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. This allows the Tricon to provide RTD failure alarming 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.

In the latter case, the actual temperature shall be available from the ALS via the Gateway computer.1.5.6 Maintenance Workstation The non-safety-related Maintenance Workstation shown in Figure 1-22 is used to maintain the Tricon and the ALS and also to view data from both.The Tricon will be isolated from the Maintenance Workstation by the qualified safety-related Triconex Communications Module (TCM). Fiber optic cable electrically isolates the Tricon from external non-safety-related devices.The ALS broadcasts data to the Maintenance Workstation via isolated one-way RS-422 data links so that a single Maintenance Workstation may be used to view data from both the ALS and the Tricon in a given Protection Set.TAB communications between the ALS and the MWS take 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 open 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].

A Maintenance Workstation may access data only within its own protection set.Communication with other protection sets is not permitted.

1.5.7 Plant Process Computer Gateway and Other Non-Safety-Related Communications Interfaces The safety-r6lated 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 Core Logic Board (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.

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, yet allows only one-way communication to the PPC 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 CC4 that will also be installed by the Process Control System (PCS) replacement project.

Process Protection System Revision:

6 Interface Requirements Specification Page 10 of 47 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 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 409 ms [1.4.4.8].

The ALS performs signal conditioning for the narrow range RTD's that support the Overtemperature AT (OTDT) 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.

The preliminary worst case (deterministic)

OTDT and OPDT PPS response time allocations are as follows: ALS: 175 ms for RTD processing Tricon: 200 ms Contingency:

34 ms Total PPS Allocation:

409 ms 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.

6 Interface Requirements Specification Page 36 of 47 2 Interface Requirements This section specifies the requirements imposed on the systems, subsystems, configuration items, 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 and digital I/O.1. All Tricon discrete inputs and outputs will be powered in accordance with the requirements provided in the I/O list.2. The Containment Pressure Bypass switch inputs to the ALS will be dry contacts wetted by 48 Vdc supplied by PG&E.3. The Pressurizer pressure loops are shared among the ALS, Tricon, and the control system, via Moore Isolator modules, and will be powered by the Tricon ETP as shown in Figure 2-2.4. Where the analog input signal source is a process transmitter, bounding loop resistances per the I/O list are as follows: a. Max resistance

< 750 ohms b. Min resistance

> 200 ohms 5. 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 adjustable power supplies which will accommodate the above bounding loop resistance values. Analog 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) 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 1) Max qualified power supply voltage: 40 Vdc 2) Max Design loop resistance at 40 Vdc input: 1325 ohms 3) Min 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 Process Protection System Revision:

5 ohms (including estimated wire resistance)" 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 Temperature Coefficient (PTC) thermistor for loop overcurrent protection and the input resistance 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 powered by redundant power supplies furnished by PG&E. The analog outputs share the same power supplies used for Tricon Main Chassis analog inputs as discussed in the previous section.b. Analog outputs in the non-safety related Triconex Remote RXM chassis will be powered by redundant 24 Vdc power supplies furnished by PG&E and mounted in the rack housing the RRXM chassis.2.1.2 Analog Inputs Figure 2-1, Figure 2-2, and Figure 2-3 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 an isolation 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 before they are input to the Tricon. Example wiring for these signals is shown in Figure 2-2.5. Tricon Al cards 3721 (where used) and 3721N shall be configured for 14-bit resolution, unipolar.

These cards are used for all 4-20 mA analog inputs to the PPS Process Protection System Revision:

6 Interface Requirements Specification Page 38 of 47 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.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 2-4 and Figure 2-5 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 for detecting the following conditions:

0 Failure to Trip on Demand 0 Trip without Demand 0 Failure to Bypass 0 Illegal Bypass Configuration of the LSM for use in an Energize to Trip (ETT) or Deenergize to Trip (DTT)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. This allows a single part number to be used to provide spares for both ETT and DTT circuit configurations.

Refer to the ALS Design Specification

[1.4.5.6]
