DCPP PPS Validation Test Plan Revision: 0 Page: 7 of 38 Date: 10/13/2011

1. Purpose and Scope 1.1. Purpose The purpose of this Validation Test Plan (VTP) is to prescribe the scope, approach, and resources of the testing activities that are required to be performed for the V10 Tricon portion of the Diablo Canyon Power Plant (DCPP) Process Protection System (PPS) to support the following:

" To detail the activities required to prepare for and conduct the system integration tests.

" To identify the tasks for responsible teams to perform and the schedule to be followed in performing the tasks.

  • To define the sources of the information used to prepare the plan.

" To define the test tools and environment needed to conduct the system test.

1.2. Scope The DCPP PPS system is classified as nuclear safety related (Class 1E), and all project nuclear safety related activities shall comply with the applicable requirements of Invensys Operations Management Nuclear Quality Assurance Manual (IOM-Q2) [Ref 2.4.1] and any additional quality requirements specified in the Project Management Plan (PMP) [Ref 2.4.5], Project Quality Plan (PQP)[Ref 2.4.6], Software Quality Assurance Plan (SQAP) [Ref 2.4.7], and Software Verification and Validation Plan (SVVP) [Ref 2.4.8].

This VTP will address safety concerns during the development of Protection Set software test specifications, procedures and test cases, Pre- Factory Acceptance Test (Pre-FAT) and Factory Acceptance Test (FAT). It will also ensure that software-contributed hazards will be tracked and mitigated adequately throughout the development lifecycle (via the Project Traceability Matrix (PTM) and Hazard Tracking List). This plan will ensure the performance of assessments of the software safety mitigation effort and their effectiveness (in each phase summary report and final report).

This VTP is prepared in accordance with Test Control, PPM 6.0 [Ref 2.4.4], Application Program Development PPM 7.0 [Ref 2.4.4], and follows the guidelines described in IEEE 1012-1998 "IEEE Standard for Software Verification and Validation" [Ref 2.1.1 ].

The PPS is composed of four separate Protection Sets (1, II, III, and IV), each comprising the V10 Tricon, the Westinghouse Advanced Logic System (ALS) platform, and the Maintenance Workstation (MWS). The ALS and MWS are not within scope of supply of this project.

However, the ALS will convert certain sensor inputs to a signal type compatible with the V 10 Tricon hardware. Specifically, the ALS will process resistance temperature detector (RTD) inputs and convert them to 4-20 milliamp signals. This conversion is necessary to satisfy Diablo Canyon Power Plant loop accuracy requirements. See the Functional Requirements Specification (FRS) [Ref 2.3.2] for additional information. These ALS inputs to the VIO Tricon will be simulated during the Factory Acceptance Test (FAT).

Title:

DCPP PPS Validation Test Plan Revision: 0 Page: 8 of 38 Date: 10/13/2011 From here on, the VIO Tricon portion of the Protection Set will be referred to as V1O Tricon Protection Set.

1.3. Test Plan Overview This VTP covers a full system test for the VIO Tricon Protection Sets. This includes application functions, system interfaces, and system performance (e.g., response time). This VTP addresses only the TriStation Application Project (TSAP) VIO Tricon Protection Set application code developed using TriStation 1131 (TS 1131). This VTP does not include V&V of the TSI 131 programming tool, which will be used to develop the TSAP software. Hardware and software procured by vendors other than Invensys Operations Management will be verified and validated by the originating organization under separate programs.

Testing is performed to ensure satisfactory hardware, software and integration system performance in accordance with Pacific Gas & Electric specifications. Equipment calibration shall be performed before testing activity and traceable to National Institute of Standards and Technology (NIST). Measures will be taken to establish that tools, gages, instruments, and other measuring and testing devices used in activities affecting quality are properly controlled, calibrated, and adjusted at specified periods to maintain accuracy within acceptable limits. Tests performed as part of system integration include:

" Pre-Factory Acceptance Test (pre-FAT)

" Hardware Validation Test (HVT)

" Factory Acceptance Test (FAT) 1.3.1. Pre-Factory Acceptance Test (pre-FAT)

The purpose of the Pre-Factory Acceptance Test (pre-FAT) is to ensure that the FAT procedure is developed properly in accordance with the VI10 Tricon Protection Set for PPS hardware, applicable software, and associated components function as designed in an operating integrated system environment.

The Pre-Factory Acceptance Test (Pre-FAT) informally executes the Factory Acceptance Test procedures to determine their suitability, correctness, completeness, and efficiency of the test procedures. Results from the Pre-FAT may be used to identify integration deficiencies.

However, the primary goal of the Pre-FAT is to improve the test procedures themselves prior to the initial run of the FAT.

1.3.2. Hardware Validation Test (HVT)

The purpose of the Hardware Validation Test (HVT) is to demonstrate that the VI 0 Tricon Protection Set hardware and interfacing hardware components function as designed in an operating integrated system environment prior to FAT.

The HVT is developed in accordance with Project Procedures Manual (PPM) 6.0, [Ref 2.4.4]. In order to complete the HVT, each test item must be initialed by test personnel and at the end of

DCPP PPS Validation Test Plan Revision: 0 Page: 9 of 38 Date: 10/13/2011 each test section an initial and date is required from test personnel, QA, and a Pacific Gas and Electric representative.

The HVT will be performed by simulating inputs at the terminal blocks for Analog Inputs (Al) and Digital Inputs (using Measurement and Test Equipment, M&TE) which are processed and made available to the non safety-related MWS via the NetOptics Port Aggregator Tap. The CAPE Software and applicable I/O modules together with hardware test software TSAP and TriStation laptop will be utilized to manipulate point values and display status as necessary.

1.3.3. Factory Acceptance Test (FAT)

The purpose of the Factory Acceptance Test (FAT) is to demonstrate that the VI 0 Tricon Protection Set for PPS hardware, application software, and associated components function as designed in an operating integrated system environment.

Note that V10 Tricon System software verification testing will be conducted prior to the FAT as part of verification and validation (V&V) of the VIO Tricon Protection Set software application under separate procedures. Software verification testing is conducted during the Implementation Phase of the project lifecycle - see the Software Verification and Validation Plan [Ref 2.4.8] for additional information.

FAT procedures are developed specific to the Pacific Gas & Electric application specifications.

Systematic testing will be based on the functional diagrams series drawings [Ref 2.3.5] and will provide for documented check-off of each step. The application program is loaded into the system and the test procedures implemented. Pacific Gas & Electric will approve the test procedures prior to starting FAT and have the opportunity to witness FAT. At the highest level, each Protection Set functions as follows:

" Perform a system service routine, which initializes, syncs, and establishes the system staging.

" Process input signals read from Tricon analog input and digital input signals.

" Perform computations for the programs.

  • Process program results and send output data from the Tricon analog and digital output modules.

iPZ 1.4.2. Software The TriStation 1131 Application Programming Software that runs on Microsoft Windows XP operating system will be used to develop the software application for the V1O Tricon Protection Sets. Invensys Operations Management will provide the TriStation 1131 software and license.

Refer to Software Requirements Specification (SRS) [Ref 2.4.10] for additional details.

1.4.3. Software that is not subject to Validation

" TriStation 1131

" Tricon Firmware

  • TS1131 Standard Libraries
  • Windows 2000/XP/7TM** - TriStation Laptop/Workstation OS
    • Windows OS, PC, and laptop (these are not tested, but functionally checked prior to test/integration activities).

1.4.4. System Communication The Class I (safety-related) V10 Tricon Protection Set will utilize two Tricon Communication Modules (TCM) in the Main Chassis to communicate with external Class II (non-safety) devices.

The fiber optic cable electrically isolates the Tricon TCM from the external Class II devices.The NetOptics Network Aggregator Tap directs the network traffic between the TCM and MWS.

The NetOptics device permits two-way communications between the non-safety MWS belonging to a specific Protection Set and the Tricon in that Protection Set, but allows only one-way communication to other non-safety systems (e.g., the PPC Gateway server computer) to be determined by PG&E (though not within the Invensys Operations Management scope). The NetOptics devices will be procured by Pacific Gas & Electric and provided to Invensys Operations Management at the start of pre-FAT.

The non-safety media converters, procured by Invensys Operations Management, will be set up between the Tricon Main Chassis and the NetOptics Network Aggregator Tap. The media

The MWS is a non-safety device that will be developed separately from the PPS Replacement Project under a separate Pacific Gas & Electric Purchase Order (PO), budget, and staff.

However, the MWS will be available during FAT to facilitate testing of the VIO Tricon Protection Sets.

The network equipment, including media converter, NetOptics Network Aggregator Tap, and gateway hub, and the MWS will not be within the test scope of this VTP. The Nuclear Delivery (ND) group will coordinate with Pacific Gas & Electric for system staging prior to turn over to Nuclear IV&V. The Nuclear IV&V group will confirm proper operation of network communications system interfaces before beginning testing addressed in this VTP. The Optical Fiber from TCM + 10/1 00baseT Ethernet Media Converter to port aggregator will be supplied by IOM.

The MWS will be utilized at the start of pre-FAT to exercise its interface with the Vi 0 Tricon Protection Set and test the TSAP application code.

1.4.5. System interfaces The following is a list of the PPS system interfaces:

" Advanced Logic System (ALS)

" Plant Process Computer (PPC)

" Main Annunciator System

" Main Control Panels

" Hot Shutdown Panel

" Solid State Protection System (SSPS)

" Rod Control System

  • Pressurizer Pressure Control System
  • Pressurizer Level Control System

" Auxiliary Feedwater (AFW) Control System

  • Reactor Vessel Level Indicating System (RVLIS)

" Low Temperature Overpressure Protection System (LTOPS)

  • Residual Heat Removal (RHR) Interlocks For additional detail refer to the Hardware Requirements Specification (HRS) [Ref 2.4.9]. The above list is only shown for overview understanding of the PPS system interfaces and they are not within the test scope of this project.

4. Wide Range Input to LTOPS provides protection against over pressurization at III Reactor low plant temperature. IV Coolant Pressure Input to Residual Heat Removal (RHR) valve interlock circuit provides protection against improper operation of RHR isolation valves.
5. DTTA Delta Temperature & Average Temperature I Overtemperature Delta-T (OTDT) Reactor Trip provides DNB II protection. The setpoint for the OTDT reactor trip and III Overtemperature Turbine Runback (OTTR)are continuously IV calculated by the PPS for each of the four reactor coolant loops.

Overpower Delta-T (OPDT) Reactor Trip provides protection against excessive power (fuel rod rating protection). The setpoint for the OPDT reactor trip and Overpower Turbine Runback (OPTR) are continuously calculated by the PPS for each of the four reactor coolant loops.

6. Pressurizer Pressurizer High Water Level Reactor Trip provides backup I Level protection to the Pressurizer High Pressure Reactor Trip and II prevents the pressurizer from becoming water solid during low III worth and low power rod withdrawal accidents.

DCPP PPS Validation Test Plan Revision: 0 Page: 25 of 38 Date: 10/13/2011 Title Description Protection 1I. Steam Steam Generator (S/G) High-High Level Turbine Trip and I Generator Feedwater Isolation (P-14, S/G High Level Permissive) provide 11 Narrow Range protection against S/G overfills and damage to the main steamlines III Level or main turbine. IV S/G Low-Low Level Reactor Trip and Auxiliary Feedwater (AFW) Pump Start protects the reactor from loss of heat sink in the event of loss of feedwater to one or more S/Gs or a major feedwater line rupture. The signals to actuate reactor trip and start AFW pumps are delayed through the use of a Trip Time Delay (TTD) for reactor power levels below 50% of rated thermal power.

The use of the TTD allows added time for natural S/G level stabilization or operator intervention to avoid an inadvertent protection system actuation.

12. Turbine Chamber Pressure High to P-13 Interlock. The purpose of the P-13 I Impulse permissive is to provide an input to P-7 indicative of low turbine II Chamber power when less than the setpoint. The purpose of the P-7 Pressure permissive is to disable selected Reactor Trip signals while operating at low power levels.

Turbine Impulse Chamber Pressure Low Interlock C-5 blocks control rod withdrawal. The purpose of the C-5 interlock is to prevent automatic outward rod motion when power is less than the design limit for Rod Speed and Direction.
