1.1 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.
Accordingly, various requirements are marked "to be provided by _ ," to indicate information that will be supplied later by others.1.2 Scope 1.3 1.3.1 The PPS is comprised of Tricon equipment provided by Invensys/Triconex and Advanced Logic System (ALS) equipment provided byWestinghouse 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 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.Electrical Class 1 E 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 1E 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 IB 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.
Process Protection System Interface Requirements Specification Revision:
4 Page 2 of 44 1.3.2 TERM DEFINITION 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, 1B, or IC requirements.
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.

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 tothe 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 a 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. The manual trip switch is used to trip the channel in the unlikely event that both ALS diversity groups are inoperable.
1.5.4 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 PG&E 120 Vac safety-related power supply. 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 out range information is provided in the I/O List [Appendix 3.1].

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 3.1.1.5.5.5 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 [3]. 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.
Process Protection System Revision:
4 Interface Requirements Specification Page 7 of 44 1.5.6 Maintenance Workstation The non-safety-related Maintenance Workstation shown in Figure 1-22 is used to maintain and configure the Tricon using the TriStation 1131 Developer's Workbench and also to view data from both the Tricon and ALS.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 is configured for one-way communications, broadcasts data to the Maintenance Workstation Dynamic Data Exchange (DDE) server, so that a single Maintenance Workstation may be used to view data from both the ALS and the Tricon in a given protection set.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-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 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. This HMI unit will obtain PPS data through a connection to the PPS Gateway Computer as shown in Figure 1-22.1.5.8 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 Process Protection System Revision:
4 Interface Requirements Specification Page 8 of 44 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 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.

4 Page 30 of 44 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 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. PG&E will provide 24-45 Vdc 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:

Reg Guide 1.180 FTP Max 48 Vdc (Approx input resistance:
(250 + 1/(1/250 + 1/3300)) -482 ohms)j) Input and output loop resistances as shown in Appendix 3.1 based on Triconex resistance above and:* Moore CPT isolator input 4-20 mA into 20 ohms* Westinghouse VX-252 indicator:
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.6. Analog outputs will be powered by 24 Vdc.2.1.2 Analog Inputs Figure 2-1, Figure 2-2, 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. TE-413A and TE-423A signals are conditioned by ALS-A and ALS-B, respectively before they are input to the Tricon. These signals are shown in Figure 2-2 only to illustrate typical wiring for analog signals that are powered externally to the Tricon ETP. The DCPP PPS Nuclear Instrumentation (NI) input channels will utilize a different Al card (3703EN) from the Al card (3721 N) used for other Tricon analog inputs and will NOT be connected to the same ETP.5. Tricon Al cards 3721 (where used) and 3721N will be configured for 14-bit resolution.
- 6. Tricon Al cards 3703E (where used) and 3703EN will utilize the default 12-bit resolution.

[Figure 1-1] using a Line Sense Module 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:
- Failure to Trip on Demand* Trip without Demand* Failure to Bypass* 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.
