Title:

DCPP PPS Validation Test Specification Revision: 1 Page: 9 of 138 Date: 04/04/2014 1 Purpose This document constitutes the entire validation test specification (VTS) for the Invensys Operations Management (IOM) portion of the Diablo Canyon Power Plant Process Protection System Replacement Project. Per PG&Es request, and as described fully in the validation test plan [Ref 3.2.5], this specification also addresses specific communication interface testing of the Tricon, NetOptics Network Port Aggregator Tap (hereafter, port aggregator), Maintenance Workstation (MWS) and KVM switch.

Under IOM process, hardware validation testing is embedded in the system validation test plans and test specifications. Therefore, this document addresses the design of protection set Tricon hardware validation testing. Note that, under IOM process, hardware validation includes a considerable amount of hardware verification testing; i.e., assessing conformance of the hardware to Hardware Requirement Specifications (HRS).

IOMs deliverables to PG&E consist primarily of four V10 Tricon systems, executing application specific TriStation Application Projects (TSAPs). The V10 Tricons are major elements in the four protection sets that make up the plant protection system; one Tricon per protection set.

The detailed description of IOMs scope of delivery, which effectively defines the items subject to validation, is provided in the project management plan (PMP) [Ref 3.2.2]. Hereafter, the four Tricons subject to this validation test are referred to collectively as the V10 Tricon Protection Set. Individually, the protections sets are denoted as Protection Set I, Protection Set II, Protection Set III, and Protection Set IV (using a Roman numeral convention).

The protection sets include equipment outside IOMs scope of delivery. Except where noted, in this document the terms Protection Set I, Protection Set II, Protection Set III, and Protection Set IV refer exclusively to the protection set components with Invensys scope of supply.

This document describes the design of all validation tests to be carried out on the V10 Tricon Protection Set. Several tests are common to one or more V10 Tricon Protection Sets, because of redundant functionality and/or design among them. Some tests are unique to a specific V10 Tricon Protection Set, because of its unique functions or design.

This document contains sufficient detail to permit the development of the validation test cases and procedures, although test case and procedure details will draw upon information in the engineering documents.

This VTS was developed in accordance with PPM 6.0: Test Control [Ref 3.2.1] and conforms to IEEE-829-1983: IEEE Standard for Software Test Documentation [Ref 3.4.2] and NRC guidance documents (Section 3.3). Table 1 describes the correlation between PPM development requirements, IEEE-829-1983 guidance, and the layout of this document.

Title:

DCPP PPS Validation Test Specification Revision: 1 Page: 11 of 138 Date: 04/04/2014 2 Scope The scope of this test specification is defined by the system validation test plan. In brief, this test specification will include hardware of all four V10 Tricon Protection Sets and their related TriStation Application Project (TSAP). MWS and the communication peripherals (media converters, port aggregator taps and touchscreen device via a KVM switch) will be utilized as test tools for complete interface tests between V10 Tricon Protection Set and MWS.

This specification does not encompass the validation testing for any other hardware or software, although it may describe the use of other hardware and software during validation testing.

As a validation test specification, this document describes those tests that assess the conformance of the test items against their requirements specifications, as found in the four V10 Tricon Protection Set software requirements specifications (SRSs) [Refs 3.2.7] and hardware requirements specifications (HRSs) [Refs 3.2.11 thru 9.2.14]. Thus, software verification testing is explicitly out-of-scope of this test specification. (Such testing is specified in the software verification test specification [Ref 3.2.6].)

In the DCPP PPS Replacement Project, there is no system requirements specification. Instead, there is a hardware requirements specification (HRS) and a software requirements specification (SRS). The SRS contains the bulk of the product functional requirements, since most functionality is implemented in software. Therefore, the SRS is tantamount to a system requirements specification, and the system validation test is carried out against the SRS. The HRS is also tantamount to a system hardware requirements specification, and the hardware validation test (HVT) is carried out against the HRS.

DCPP PPS Validation Test Specification Revision: 1 Page: 19 of 138 Date: 04/04/2014 6 Features to be Tested This section describes the features (i.e., functional, performance, and other requirements) to be tested. It specifically identifies the features that apply to each of the four V10 Tricon Protection Sets, as well as to the port aggregator. Not all test item features will be validation tested. See Section 7 for identification of features that will not be tested, including justification for not testing those features during validation testing.

6.1 Har dwar e Validation Testing Hardware validation testing, under IOM process, involves substantial hardware verification activity. HVT assesses whether the completed V10 Tricon Protection Sets satisfy the requirements specified in their respective hardware requirements specifications (HRSs). The Tricon platform is supplied with certificates of conformance for the internal components of the platform. No verification testing of those components is required. However, as further verification of the assembled hardware, the following features are tested as part of hardware validation testing:

• Tricon Power modules

• Tricon I/O modules

• I/O module points, including spare points specified in drawings or the HRS

• Tricon Communication Modules interface with MWS

• Loop Instrument power supplies 6.2 System Validation Testing System validation testing assesses whether the completed V10 Tricon Protection Sets satisfy the requirements specified in their respective software requirements specifications (SRSs). The FRS

[Ref 3.1.2], and IRS [Ref 3.1.4] provide the system-level requirements. The requirements applicable to the V10 Tricon (i.e., Invensys scope of supply) were translated into software and hardware requirements, and those are the basis of validation testing.

System validation testing addresses the requirements categories shown in Table 2, taken from the indicated sections of the SRS.

DCPP PPS Validation Test Specification Revision: 1 Page: 23 of 138 Date: 04/04/2014 8.2 Har dwar e Validation Testing Hardware validation testing validates the V10 Tricon Protection Sets hardware against their respective HRSs. The HVT purpose and scope are defined in the validation test plan. That plan provides a basic description of the test approach. This document provides additional test approach information.

8.2.1 Hardware Configuration The hardware being validated is the deliverable V10 Tricon Protection Set hardware for Protection Set I, Protection Set II, Protection Set III, and Protection Set IV. The V10 Tricon Protection Sets components are provided with certificates of conformance from the IOM Tricon manufacturing facility. Prior to hardware validation testing, the hardware is assembled in the IOM Lake Forest facility, in a climate-controlled, secure test environment. All four V10 Tricon Protection Sets are received, assembled, and tested in this facility, at essentially the same time.

Title:

DCPP PPS Validation Test Specification Revision: 1 Page: 25 of 138 Date: 04/04/2014 8.2.3 Outline of Hardware Validation Testing HVT is performed in parallel (not necessarily simultaneously; i.e., in lock step) on each of the four V10 Tricon Protection Sets.

The testing first verifies that the hardware configuration is correct. This is accomplished through a series of inspections, power-on tests, and calibration verification steps, to confirm the hardware configuration conforms to design documentation and is in proper working order.

Testing continues via the execution of the hardware validation test procedures, which comprise the hardware validation test cases. (These tests identify the set of hardware validation tests that will sufficiently verify and validate the Tricon Protection Sets against their design descriptions and requirements specifications.)

Per the software verification and validation plan (SVVP) [Ref 3.2.4]; HVT results are documented in the hardware validation test report.

8.3 System Validation Testing System Validation Testing (SysVT) validates the V10 Tricon Protection Sets against their respective software requirements specifications.

The test targets are the four deliverable V10 Tricon platforms loaded with the four deliverable TriStation application projects (TSAPs), each one developed specifically for a specific V10 Tricon Protection Set: Protection Set I, Protection Set II, Protection Set III, and Protection Set IV.

SysVT is performed on each V10 Tricon Protection Set using (via) Factory Acceptance Test procedure (FAT) by Nuclear IV&V personnel, supported by Nuclear Delivery personnel and Nuclear QA personnel. The tests may be witnessed by PG&E representatives.

Before System validation testing can begin on any individual V10 Tricon Protection Set, the following prerequisites must be met, in the order shown, for that V10 Tricon Protection Set.

DCPP PPS Validation Test Specification Revision: 1 Page: 26 of 138 Date: 04/04/2014 8.3.3 Test Anomalies In the event a V10 Tricon Protection Set is found to be in nonconformance with its requirement specifications, or in case of any abnormal test conditions, the anomaly is documented on a System Integration Deficiency Report (SIDR), in accordance to PPM 6.0 and PPM 10.0, Nonconformance and Corrective Action. Software anomalies are also documented per PPM 7.0.

8.3.4 Test Environmental Conditions System validation tests are carried out under the normal environmental conditions (temperature and humidity) of the Triconex facility.

DCPP PPS Validation Test Specification Revision: 1 Page: 32 of 138 Date: 04/04/2014 9.3.2 SRS Tag Traceability In general, each test case identifier is traceable to a single or multiple requirment elements in the SRS. Each requirment element is tagged by a base requirement ID (R-#) or a derived requirement ID (DR-#), which is specified in the SRS.

The test cases traceability is documented in the initial revision of the Validation Test Specification. As the Validation Test Specification is updated with PG&E design inputs revision 9, it is also streamlined with the removal of the test cases traceability from this revision of the specification and moving forward. The test cases traceability will be part of the Implementation-phase PTM referenced by this specification.

The streamlining effort of moving the test cases traceability from the Validation Test Specification to the PTM complies with IEEE 829-1983 guidance on the test cases traceability and requirement coverage and completeness.

9.4 Factor y Acceptance Tests Design The following sections represent the general categories of V10 Tricon Protection Set features subject to system validation testing. Each section identifies system validation tests of those features.

The tests are assigned identifiers that are used as the test procedure identifiers. Only a brief description of the test is provided, the aim being only to identify the number and types of tests that make up factory acceptance testing. Test details are provided in the test procedures and test cases.

Tracing back to the SRS requirements is accomplished via the test identifier and the project traceability matrix.
