I Page: 6 of 24 Date: 10/14/2011 1 Introduction 1.1 Purpose The Software Integration Plan (SIntP) describes the system integration strategy for the Diablo Canyon Power Plant (DCPP) Process Protection System (PPS) Replacement Project. The SIntP describes generally the strategy for integrating the V10 Tricon Protection Set software functions together into a Tricon System Application Program (TSAP). integrating the TSAP with the hardware, and the steps involved in the software integration process. Without a Software Integration Plan it is possible that the integrated system will lack important elements, or that some integration steps will be omitted. The form and content for the SIntP is based on Sections 3.1.7 and 4.1.7 of NUREG CR-6101 [Ref. 1.4.3.1].The integration process begins in the Implementation Phase of the project lifecycle in accordance with the Project Procedures Manual when the software functions for the PPS Protection Set are developed using TriStation 1131 (TS 1131) (see Appendix 2 Exhibit 2 -Application Software Development, section 2.3 of the Project Procedures Manual (PPM) [Ref. 1.4.4.1.1).

The application software is an implementation of the software detailed design documented in the PPS Replacement Project Software Design Descriptions (SDDs), [Ref. 1.4.4.21, 1.4.4.27, 1.4.4.28, and 1.4.4.29], ', using the latest released version of TS 1131 listed on the Nuclear Qualified Equipment List (NQEL)[Ref. 1.4.4.1 0].A Nuclear IV&V Implementation Phase Summary Report shall be prepared to summarize Implementation Phase project activities.

The project Software Development Plan (SDP),[Ref. 1.4.4.21 ], describes the software development process for the PPS Replacement Project. The PPM contains the set of implementing procedures for the PPS Replacement Project [Reference 1.4.4.1].Software integration consists of three major steps: 1) Integrating the various software programs into a single TSI 131 project file (i.e., PT2 file), 2) Integrating the TS 1131 PT2 file with the V 10 Tricon hardware, 3) Testing the integrated V10 Tricon product.During the first step, standard TS 1131 function blocks are combined to produce Programs that implement the Protection Set protective functions.

These programs implement the software design described in the four Protection Set SDDs [Ref. 1.4.4.21, 1.4.4.27, 1.4.4.28, and 1.4.4.29], which are, ultimately, based upon the functional requirements contained in the customer input documents, including the Conceptual Design Document [Ref. 1.4.2.2], the Functional Requirements Specification

[Ref. 1.4.2.11, the Interface Requirements Specification

[Ref. 1.4.2.3], and the Functional Block Diagrams [Reference 1.4.2.4].

The individual TS 1131 programs are combined into a Master TSAP project file (PT2 file). Once all the protection functions have been implemented in accordance with the SDDs, a Software Development Checklist is generated and the TSAP issued'A SDD will be developed for each of the four PPS Protection Sets. For simplicity, they will be identified collectively as 993754-1-810

[Ref. 1.4.4.21, 1.4.4.27, 1.4.4.28, and 1.4.4.29].

See the Project Management Plan, [Ref. 1.4.4.22], for additional details on the project document numbering scheme.

The second step involves staging the system in a secure area and loading the TSAP (PT2 file). The V 10 Tricon equipment, materials, parts, and components are staged in a secure location that can accommodate system integration construction, assembly, inspection, and testing activities, as explained in the Regulatory Guide 1.152 Conformance Report [Ref. 1.4.4.24].

All items listed on a project bill of material will be staged and adequately protected to prevent loss or damage. Only authorized personnel will be allowed access to the staged system. System assembly and initial power-on testing is performed in accordance with the PPM. After initial checkout, the staged V10 Tricon Protection Set equipment is formally turned over to Nuclear IV&V in preparation for Test Phase system validation testing.The final step consists of validation testing of the staged system comprising the VI10 Tricon Protection Set hardware and TSAP. The testing activities are defined in the project Hardware Validation Test (HVT) [Ref. 1.4.4.3 11 and Factory Acceptance Test (FAT) [Ref. 1.4.4.34]procedures.

The validation testing is the responsibility of the Nuclear Independent Verification

&Validation (IV&V) staff, including configuration control of the staged equipment, test tools, and test documentation, until completion of validation testing.Figure 1 PPS Replacement Design Concept n v'e. n s" s Operations Management inv e.n s" Triconex Document:

I Page: 8 of 24 Date: 10/14/2011 7 1.2 Scope This Software Integration Plan applies only to the software programs associated with the V 10 Tricon portions of the PPS, shown in Figure I PPS Replacement Design Concept.1.3 Definitions and Acronyms 1.3.1 Definitions Configuration Function Function Block Network"The arrangement of a computer system or component as defined by the number, nature, and interconnections of its constituent parts." (as per reference 1.4.4.6) Note -it is interpreted that a "component" in the context of this definition includes the library functions and function blocks included with TriStation 1131 Program Developers software.A function is a logic element which yields exactly one result. Unlike a function block, the data associated with a function is not retained from one evaluation of the function to the next. Functions do not have to be instanced.

A function block is a logic element which yields one or more results.To use a function block in a program, an instance of the function block must first be declared.

Each instance is identified by a user-defined instance name. All of the data associated with a specific instance of a function block is retained from one evaluation of the function block to the next.The individual subdivisions of a Tricon Program written using Function Block Diagram logic.Within the Tricon Project file, the collection of user defined logic structures which define the logic executed by the controller.

The overall configuration file which defines the operation of a Tricon controller.

A general purpose, high-level programming language, similar to PASCAL or C. Structured Text is particularly useful for complex arithmetic calculations, and can be used to implement complicated procedures that are not easily expressed in graphical languages.

I Page: 14 of 24 1 Date: 10/14/2011 2 Identification of Integration Process 2.1 Integration Level This Software Integration Plan (SIntP) specifies levels of integration consistent with the Software Requirements Specification (SRS) and Software Design Description (SDD) and also specifies objects needing to be included at the Hardware, Software, Instrumentation, and Data level. The scope of the integration process can be broken down to the various objects that will be included in each integration step of each level.The PPS Replacement system is composed of the V10 Tricon and the Westinghouse ALS, as shown in Figure 1; but only the V10 Tricon is within the scope of this SIntP, thus multiple levels of integration are not required.

However, several integration steps will be required at that single level.2.2 Integration Objects and Strategies This section lists all objects included in each integration step as well as a strategy for the integration process.As mentioned in section 1.1 of this document, the three integration steps are executed sequentially:

I) Integrating software units (functions, program) in each TSAP.2) Integrating software with VIO Tricon hardware (chassis, MP, TCM, and I/O modules).3) Testing the integrated system with simulated I/O signals and the Maintenance Workstation.

Steps at more detailed levels are generally required to be completed successfully before a step at a more general level can be performed.

The integration sequence is shown in Figure 4 Integration Process Sequence below: After the factory acceptance test results are accepted by PG&E (which may require returning to previous project life cycle phases and regression analysis and testing, the final Nuclear IV&V report w i n v'e. n s'.ý= s, M T i n Ve. n s" Operations Management Triconex Documnent:

Once the System Integration Document Package is signed off and the equipment is packaged, the system integration activities under this plan end. It is important that the quality records (e.g., design documentation, TSAP Project files, and Nuclear IV&V reports) are packaged with the validated V 10 Tricon Protection Set equipment and shipped to the customer.

Therefore, the scope of this plan extends past the software-hardware integration steps to include final packaging for shipment to the customer.4.2 Personnel and Responsibilities The full details on project personnel, their responsibilities, and project organizational structure are discussed in the Project Management Plan (PMP) [Ref. 1.4.4.22].

Referring to Figure 3: PPS Replacement Project Organization Structure in the PMP, the following two highlighted groups will be responsible for software integration:

1) Software Design 2) Nuclear Independent Verification

& Validation (IV&V) Staff The customer technical requirements are translated into project documents and drawings such as the project Software Requirement Specification (SRS)2 [Ref. 1.4.4.11, 1.4.4.12, 1.4.4.13, and 1.4.4.14], which, in turn, is translated into software design configuration items in the Software Design Description (SDD) [Ref. 1.4.4.26, 1.4.4.27, 1.4.4.28, and 1.4.4.29].

Then the Software Design team, under direction of the Project Engineer, develops the TriStation Application Project (TSAP) using TriStation 1131.The V10 Tricon Protection Sets will be built by the Hardware Design team, also under direction of the Project Engineer, based on project Hardware Requirement Specification (HRS)3 [Ref. 1.4.4.15, 1.4.4.16, 1.4.4.17, and 1.4.4.18]

that has been translated into mechanical and electrical drawings.After assembly and QA/QC checkout, the V 10 Tricon Protection Set equipment will be transferred to Nuclear IV&V for Hardware Validation Testing [Ref. 1.4.4.33]

and Factory Acceptance Testing[Ref. 1.4.4.34]

in accordance with the Software Verification and Validation Plan [Ref. 1.4.4.12].

The personnel who will be involved in the integration activity are listed and kept up to date in accordance with the NSIPM [Ref. 1.4.4.2].

A copy of project personnel qualification and training records will be included in the PPS Replacement Project document file. See the Project Management Plan [Ref. 1.4.4.22]

for additional details on project training requirements.

2 An SRS will be developed for each of the four PPS Protection Sets. For simplicity, they will be identified collectively as 993754-1-809
