Each phase of the project, e.g., System Requirements Phase, Hardware Requirements Phase, Design Phase, and others, shall be covered by a subsection that documents in detail the V&V efforts during that phase, and the results thereof, including anomalies discovered and their resolution and consequent rework, reverification and revalidation. The documentation that each phase has been completed in full compliance with the requirements of that phase with respect to the specifications shall be included or specifically referenced from among the other required project documentation. The final report will consist of these subsections, together with subsections providing an overview and a summary of the entire V&V effort. The Requirements Traceability Matrix shall be included as an appendix to the final VVR. The format of the report will generally follow the outline below: 1. Purpose/Applicability/Limits/Exclusions of this VVR 2. Summary/Overview of the Project V&V effort 3. System Requirements Phase V&V Revision 2.1 2/18/2008 Page 4 of 24 ALS Class lE Controls: MSFIS V&V Report 4. Hardware Requirements Phase V&V 5. Design Phase V&V 6. Implementation Phase V&V (including Pre-Production Test Report)7. Test Phase V&V (including Final Acceptance Test Report)8. Installation and Checkout Phase V&V The VVR will supplement the Nutherm Qualification Test Report (QTR) by providing the details of the qualification of the system.The VVR shall be prepared by the V&V Engineer, and approved by the ALS MSFIS Project Manager.1.2 Reference Material Binding documents applicable to this VVR for this project are: 1.2.1 Wolf Creek Nuclear Operating Company (WCNOC) Specification J-105A(Q)1.2.2 CMP -Configuration Management Plan for Class 1E Qualified ALS MSFIS 1.2.3 WCNOC Procedure AP 05F-001 -Design Verification 1.2.4 WCNOC Procedure AP 05-002 -Dispositions and Change Packages 1.2.5 WCNOC Procedure AP 05-005 Design, Implementation & Configuration Control of Modifications 1.2.6 MSFIS V&V Report, CSI document 6101-00200 1.2.7 Qualification Test Report, Nutherm document WCN-9715R Revision 2.1 2/18/2008 Page 5 of 24 Revision 2.1 2/18/2008 Page 5 of 24 ALS Class 1E Controls: MSFIS V&V Report 2.1 Organization This section describes the organization for design/development and V&V of the subject system.The project includes three independent groups, under the oversight of the ALS MSFIS Project Manager and WCNOC Design Change Process: 1. WCNOC Design Change Process -responsible for the design and implementation of modifications at WCGS using established WCNOC processes and procedures (AP 05-005, Design, Implementation & Configuration Control of Modifications and AP 05-002, Design Change Process). As a part of the established processes and procedures, an independent V&V of the Design Change Package is performed by a qualified WCNOC Engineer. This independent V&V is in addition to the V&V activities performed by the Class 1 E Controls Supplier, the Qualification and Quality Oversight Contractor, and the V&V Engineer. A summary of all V&V activities is shown in Figure 1.2. Class 1E Controls Supplier -responsible for the design, development, integration, and final delivery of the product. For this project, CS Innovations (CSI) is providing this function.3. Qualification and Quality Oversight Contractor -responsible to provide both oversight and direct actions to independently ensure that the requirements on qualification of safety related hardware for the Class 1E system, including its performance, integration, configuration control, and documentation, are satisfied. Nutherm International (NI)performed this function.4. V&V Engineer -responsible to provide independent oversight and direct actions to ensure that the V&V requirements for a Class IE system are satisfied. Baseline Engineering is providing this function as staff augmentation to WCNOC Engineering. The V&V Engineer shall review and credit all underlying V&V activities performed by the Class lE Controls Supplier and/or the Qualification and Quality Oversight Contractor.

As noted above, CSI is now the Class 1 E supplier, and NI's role for the ALS MSFIS project is to provide environmental qualification (EQ) and supplemental, or"augmented", quality oversight. This results in some duplication of quality efforts on the project. CSI has independently performed some additional EMC testing (informally) and has also performed an additional Factory Acceptance Test (FAT). These activities are documented in the CSI MSFIS V&V Report (ref.1.2.6).Prior to implementation of the new procurement structure WCNOC performed a Part 50 Appendix B audit of CSI. This performance based supplier audit focused on the supplier's in-process activities that are needed to reach a conclusion about whether items produced by the supplier's process will perform their intended function. This audit relied, in part, on the confirmatory acceptance testing that was performed by NI. The audit results concluded that the CSI Quality Assurance Program was well implemented and satisfies the requirements of 10 CFR 50 Appendix B. WCNOC's audit of CSI's 10 CFR 50 Appendix B Quality Assurance Program and performance of the independent reviews and qualification testing by NI, combined with WCNOC quality and engineering personnel oversight surveillance activities, provided the basis for the approval of CSI's 10 CFR 50 Appendix B Quality Assurance Program to supply WCNOC with safety related material.

Seismic Test Procedure EMC Test Procedure Revision 2.1 2/18/2008 Page 10 of 24 ALS Class IlE Controls: MSFIS V&V Report 2.4 Tools, Techniques and Methodology 2.4.1 Tools One special tool is used in the V&V process, as follows: 1) A software tool (IBM Rational Pro) for tracking system requirements from the original specification through the various design documents, and generating the Requirements Traceability Matrix.2.4.2 Techniques and Methodologies The fundamental methodology is to verify and document that each phase of the system development life cycle resulted in a product that satisfies the requirements for that phase. It must be proven that all elements of the design conform to the requirements. Further, it must be demonstrated that the integrated product performs all of the required functions, with no unintended functions. To assure adequacy of the design and to facilitate the performance of the V&V process the following steps were taken: a. Detailed, well defined requirements were established and formatted to facilitate verification that each requirement is satisfied, e.g., to facilitate testing and tracking.b. To the maximum practicable extent, requirements were specified in well defined mathematical language, such as logic diagrams, state tables, or other unambiguous forms.c. A Requirements Traceability Matrix is maintained to facilitate verification that the requirements were correctly propagated forward through the design, testing and validation steps of the development process, and so that validation at each phase of the development process is related specifically to these requirements.

d. Testing is defined and derived from the established requirements.

e. Testing results are well documented.

f. Configuration management are enforced.Revision 2.1 2/18/2008 Reviion .1 /18/008Page I11 of 24 ALS Class IE Controls:

MSFIS V&V Report The life cycle used in this project follows the "waterfall" model and includes the following phases: 1) System Requirements Phase 2) Hardware Requirements Phase 3) Design Phase 4) Implementation Phase 5) Test Phase 6) Installation and Checkout 7) Operation and Maintenance

3.1 Management

The management of the V&V process for this project entails a close working relationship between the V&V Engineer and the ALS MSFIS Project Manager, to define the "fine structure" for the V&V work within the framework defined in this document. The V&V report (this document) is prepared and maintained as a living document during the life of the project by updating and adding material as each phase of the project is completed and any necessary iterations are performed. 3.2 System Requirements V&V 3.2.1 Overview System requirements were established by WCNOC in Specification J-105A(Q). CSI used this document to base the preparation of the conceptual design. One V&V step was taken in this phase: 1) Critical review of J-105A(Q) and resolution of comments and questions deriving there from.Revision 2.1 2/18/2008 Page 13 of24 Revision 2.1 2/18/2008 Page 13 of 24 ALS Class 1E Controls: MSFIS V&V Report The principal V&V method used in this phase was the critical review of the WCNOC specification followed by discussions to resolve any comments or questions. The Requirements Traceability Matrix was initiated to provide a formalized database that provides item number by item number correlations. Particular attention was given to assuring that the requirements are amenable to demonstration by test of the completed system. Approval was obtained from the CSI Lead Design Engineer, Qualification and Quality Oversight Contractor (NI), V&V Engineer and the Project Manager following resolution of all comments resulting from the System Requirements Verification. The criteria for satisfactory completion of this phase was the agreement by all parties that closure was achieved on all comments and that each individual technical requirement could be demonstrated through either test or analysis.3.2.2 Inputs/Outputs The inut for this phase was the initial J-105A(Q) specification, Revision 1.The output for this phase was the resolution of comments and issuance of Revision 2 of the J-105A(Q)specification. 3.3 HARDWARE REQUIREMENTS V&V The hardware requirements phase consisted of one step: 1) The preparation of the System Requirements Document (SRD, CSI Document 6101-00002, "MSFIS System Specification, Wolf Creek Generating Station"). The SRD provides a structured delineation of the system requirements contained in the J-105A(Q) specification that are satisfied by the design, and the manner and structure in which the design will function to satisfy those requirements. The SRD addresses:

a. Process inputs, including test inputs.b. System logic required for operation of the MSFIS.c. Process outputs, including ranges, accuracies, update interval, and human factors considerations of the operator interface.

d. Initialization requirements such as initial values and start-up sequence.e. Logic for response to detected failures.f. Operator interfaces (control panels, displays).

Revision 2.1 2/18/2008 Page 14 of 24 ALS Class 1E Controls: MSFIS V&V Report g. Automated in-service test and diagnostic capabilities.

h. Timing requirements for all time dependent events, including overall system requirements.

i. Limitations on processing time.j. Security requirements such as passwords.

k. Design features that provide administrative control of all devices capable of changing the content of stored setpoints and logic.1. Initialization requirements such as power-up and power-down.

m. Design features for the detection of system failure.n. Manually initiated in-service test or diagnostic capabilities.

o. Human factors engineering design features encompassing operator interfaces associated with operation, maintenance, and testing.p. Mechanical and electrical interfaces with existing systems and structures.

q. Design features necessary to assure satisfaction of the seismic and electromagnetic interference design requirements for the system.The SRD includes all of the technical requirements of the project in a form that facilitates tracking back to the statements of the J-105A specification, and forward to the succeeding phases of the development program.3.3.1 Verification and Validation Tasks The V&V tasks for the requirements phase consisted of independent reviews of the documents prepared in this phase against the WCNOC J-105A(Q) specification.

All questions, comments or anomalies found during the reviews were documented and resolved before proceeding to the design phase of the development process.Revision 2.1 2/18/2008 Page 15 of24 Revision 2.1 2/18/2008 Page 15 of 24 ALS Class 1E Controls: MSFIS V&V Report 3.3.2 Methods and Criteria The Requirements Traceability Matrix was updated to confirm that the complete set of J-105A specification requirements were covered by the SRD. This step included: 1. Tracing the requirements to the system requirements.

2. Review of identified relationships for correctness, consistency, completeness, and accuracy.3. Review to assure the requirements are testable.4. Assessment of how well system requirements were satisfied, and identification of key performance and critical areas of the design.3.4 DESIGN PHASE V&V The Tasks for the Verification and Validation of the design phase of the development process for the ALS MSFIS consisted of several activities as follows: Review, approval, and issue of the CSI Documents 6101-00002, MSFIS System Specification, Wolf Creek Generating Station prepared by the design team to satisfy the requirements of the WCNOC J-105A(Q) Specification.

Revision 3 of J-105A(Q) was issued on 6/29/07. This revision resolved several issues that were raised during the design phase and represents the "final" specification version moving forward from the Design Phase.Preparation and issue by the Design Contractor /Class 1E Controls Supplier of the following documents:

Final Acceptance Test 9715-TPS-9064 Review and approval of the Electromagnetic/Radio Frequency Interference Test Procedure prepared by the Qualification and Quality Oversight Contractor, to confirm that the system will perform satisfactorily Revision 2.1 2/18/2008 Page 18 of 24 ALS Class 1E Controls: MSFIS V&V Report in the EMI environment typical of a power plant control room, and will not affect other equipment installed there.EMC Test Procedure 9715-EMC-01 Review and approval of the Seismic Test Procedure prepared by the Qualification Contractor, to confirm that the system will remain functional during and after the seismic disturbances specified for the plant site.Seismic Test Procedure S-128P The Qualification and Quality Oversight Contractor issued the Dedication Plan for WCNOC review and approval. The Dedication Plan defines the ALS MSFIS Critical Characteristics and the applicable processes and standards to be applied in the commercial grade dedication of the equipment, in accordance with EPRI NP-5652. Review comments were incorporated and a final Dedication Plan was issued.Dedication Plan WCN-9715DP The Qualification and Quality Oversight Contractor completed a number of commercial grade surveys which included review of the Design Contractor /Class 1E Controls Supplier's design process / design architecture and found the controls and process to be adequate. The dates of the surveys are provided on the timeline diagram in Figure 2. The source surveillance and commercial grade survey were based on review of objective evidence of work performed by the Design Contractor /Class lE Controls Supplier on the ALS MSFIS project. The Qualification and Quality Oversight Contractor will include a detailed report of their reviews in the final Dedication Report.(Note: As discussed in section 2.3.3, the Qualification Contractor (NI) was responsible for all aspects of the Class lE qualification as the ALS MSFIS System procurement was originally structured. The Design Contractor (CSI) is now providing the equipment under their own Appendix B program, so some of the dedication activities have been re-iterated. The dedication activities provided by NI will be utilized at WCNOC as augment quality items and reports.)The Design Contractor /Class 1E Controls Supplier issued a Safety Assessment of the ALS MSFIS. The Safety Assessment analyzes the Functional Failure Paths of the MSFIS and from this analysis determines the safety assurance levels for major components. The safety assessment provides both a qualitative and quantitative analysis of the ALS MSFIS reliability and availability. MSFIS Safety Assessment 6101-00006 The Methods employed in the Verification and Validation of the Design Phase consisted principally of visual review of documents and drawings against the preceding phase Outputs and the engineering Revision 2.1 2/18/2008 Page 19 of 24 ALS Class 1E Controls: MSFIS V&V Report experience of the reviewers, and the writing of original documents to cover the required testing. The Criteria for acceptance were the projections of the experienced personnel performing the work that the documents being reviewed and prepared would meet the requirements of the Wolf Creek specification and work properly after installation irrespective of the specification requirements. The Inputs for the Verification and Validation of the Design Phase were the Wolf Creek J-105 specification and the CSI ALS Level-1 System Specification (6000-00000). The Outputs of the Verification and Validation of the Design Phase were the approvals of the several documents and drawings, and the approved test procedures. No Iterations affecting the outputs of previous phases were required, affecting either the Conceptual Design or Requirements Phases.3.5 IMPLEMENTATION and TEST PHASE V&V 3.5.1 Implementation Phase The implementation phase included the assembly of the first set of hardware, preliminary tests of operability, performance of the Preproduction Test by CSI, and performance of the Seismic and EMC tests by NI. The assembly and testing of the remaining production units was completed following satisfactory completion of the qualification testing.3.5.1.1 Verification and Validation Tasks The V&V Engineer worked closely with the design and qualification teams throughout this phase to ensure that the project objectives, as defined in the various levels of specifications were satisfied. The V&V Engineer verified that anomalies were being recognized and resolved in accordance with controlled processes. 3.5.1.2 Methods and Criteria The implementation phase consisted of the performance of the following tests: Seismic Test in accordance with Nutherm Seismic Test Procedure S-128P EMC Test in accordance with Nutherm EMC Test Procedure 9715-EMC-01 Preproduction Test in accordance with CSI ALS Board Test Plan 6000-00008 and MSFIS System Test Plan 6101-00004 Revision 2.1 2/18/2008 Page 20 of 24 ALS Class 1E Controls: MSFIS V&V Report 3.5.1.3 Inputs/Outputs Inputs to the V&V effort for this phase were the system design documents, the hardware, the Pre -Production Test Procedure, the Seismic Test Procedure, and the EMC Test Procedure. Outputs of the V&V effort for this phase were updates to the previously prepared V&V documentation, test procedure reviews and approvals, changes to the test procedures required as a result of any iterations initiated in this phase, and the test reports.Details of the Implementation Phase tests are as follows: The initial issue of the seismic test procedure was S-128P Rev.0, issued on 11/15/06. S-128P Rev.1 was issued on 12/22/06 for WCNOC review and comment, and S-128P Rev.2 was issued on 1/8/07 to incorporate the approval comments.The seismic test was performed on 1/11/07 at Wyle Laboratories. The seismic testing was completed successfully as documented in NI Qualification Report WCN-9715R Rev.0.The initial issue of the EMC test procedure was 9715-EMC-01 Rev.0, 11/26/06. Subsequently, Rev.1 was issued on 11/28/06 to incorporate clarifications and to add a "Safety Function Actuation Test". 9715-EMC-01 Rev.2 was issued on 12/04/06 to include CSI equipment grounding recommendations. Rev.3 was issued on 12/14/06 to add a note regarding the rationale for power lead surge withstand level tests.The final EMC test procedure revision, 9715-EMC-01 Rev.4 was issued on 12/19/06 to add test levels for the IEC 61000-4-4 Ring Wave Immunity Test, add a re-test of the IEC 61000-4-4 Electrical Fast Transient/Burst Immunity Test, and to add re-test, pre-test, and post-test verification sheets.CSI conducted several EMC "pre-tests" at a local National Technical Systems subsidiary in Phoenix, AZ from August 2006 through November 2006. These tests were performed to validate the ALS board designs against NRC RGI.180 / EPRI TR-102323 Revision 2 and also EPRI TR-102323 Revision 3, prior to formal testing.Formal EMC testing was performed 12/07 at Elite Electronic Engineering. Testing was satisfactorily completed, however anomalies that arose during IEC 61000-4-3 (Radiated Immunity, 26MHz to 10Ghz), IEC 61000-4-4 (Electrical Fast Transients), and IEC 61000-4-5 (Surge Immunity) resulted in minor modifications (grounding arrangement and surge suppression design) to the test specimen to achieve a satisfactory result. These modifications are detailed in the Nutherm EMC Test Report, WCN-9715ER Rev.0, dated 2/16/07 and in the following CSI Engineering Change Notices (ECN's): ECN 101-0000 -Modification to ALS-411 boards due to MOV early clamping during Surge testing ECN 101-0001 -Modification to ALS-905 boards due to capacitor early clamping during Surge testing ECN 101-0002 -Modification to MSFIS Assembly Panel to avoid fuses blowing during surge testing Revision 2.1 2/18/2008 Page 21 of 24 ALS Class 1E Controls: MSFIS V&V Report The ECN's are listed in Reference 1.1.6.EMI qualification testing was completed successfully as documented in NI Qualification Report WCN-9715R Rev.0. CSI revised the Bills of Material (BOM's) and equipment drawings to incorporate the surge suppression and grounding changes made during EMI qualification, and these changes were reflected in the production equipment. The preproduction test was completed satisfactorily on the qualification unit, and the test report is contained in the CSI equipment travelers.
