ALS Class IE Controls: MSFIS V&V Report 2.1 Organization This section describes the organization for design/development and V&V of the subject system.
The V&V organization includes three independent groups, under the oversight of the ALS MSFIS Project Manager and WCNOC Design Change Process. The three groups are represented in Figure 2-1:
- 1. WCNOC - 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, Dispositions and Change Packages). Baseline Engineering is providing the function of a project V&V Engineer. The project V&V Engineer is responsible to provide independent oversight and direct actions to ensure that the V&V requirements for a Class 1E system are satisfied. The V&V Engineer shall review and credit all underlying V&V activities performed by the Class 1E Controls Supplier and/or the Qualification and Quality Oversight Contractor. In addition to the V&V Engineer, 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 Design Contractor/Class 1E Controls Supplier, the Qualification and Quality Oversight Contractor, and the project V&V Engineer. A summary of all V&V activities are shown in Figure 2-2.
- 2. Design Contractor/Class 1E Controls Supplier (CS Innovations) - 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 (Nutherm International) -
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.

ALS Class 1E Controls: MSFIS V&V Report Subsequent to the issue of the VVR, Revision 1 (8/31/07), WCNOC implemented a revised procurement structure for the MSFIS equipment. As noted above, CSI is now the Class 1E 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 MSFIS V&V Report (CSI document 6101-00200).
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 N1. 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. Figure 2-3 provides a timeline depicting the activities associated with the ALS MSFIS controls.

ALS Class 1E Controls: MSFIS V&V Report 2.2 Configuration Management Responsibilites 2.2.1 V&V Staffing:
The V&V Engineer has a broad background and experience in the design, development, test and operation of nuclear power plant instrumentation and control systems, and the standards and practices in this discipline, particularly regarding the experience in applying digital computer technology in these applications. The V&V Engineer shall perform and/or direct the performance of the V&V activities of the project.
2.3 Tasks and Responsibilities This section identifies the responsibilities of specific individuals and organizations within the framework of the VVR.
2.3.1 Project Manager Responsibilities The ALS MSFIS Project Manager is responsible either personally, or through the actions of others, for the performance of the entire ALS MSFIS Project, including all aspects of design, development, manufacture, testing, and shipping. The following elements of V&V related activities are included in these responsibilities:
Prepare System Specification Prepare Project Plan Coordinate subcontracted design, qualification and testing 2.3.2 Verification and Validation Engineer Responsibilities The V&V Engineer is an independent individual that is responsible to supervise and/or perform the System V&V Plan including the content of the documentation thereof. Responsibilities include:
Perform and/or supervise verification and validation activities for each project phase.
Prepare the following plans:
System V&V Plan MSFIS Configuration Management Plan (CMP)
Revision 2.5 1/25/2009 Page 12 of 29
ALS Class 1E Controls: MSFIS V&V Report Prepare the following documents:
MSFIS V&V Report (VVR)
Requirements Traceability Matrix (RTM)
System Reliability Analysis (SRA)*
Failure Modes and Effects Analysis (FMEA)*
- The SRA and FMEA, although not "traditional" V&V functions, are being performed by the V&V engineer. The reports will be included in the VVR, Revision 3, as significant factors in the total system V&V process.
2.3.3 Qualification and Quality Oversight Contractor Responsibilities The following elements of V&V related activities are included in these responsibilities:
Prepare the following plans:
Qualification Plan (Note: The Qualification and Quality Oversight Contractor (NI) was responsible for all aspects of the Class 1E qualification as the ALS MSFIS Controls procurement was originally structured. The Design Contractor/Class 1E Controls Supplier (CSI) is now providing the equipment under their own Appendix B program, so some of the dedication activities have been re-iterated. )
Prepare the Following Procedures:
Seismic Test Procedure EMC Test Procedure 2.4 Tools, Techniques and Methodology 2.4.1 Tools One special tool is used in the V&V process, as follows:
Revision 2.5 1/25/2009 Page 13 of 29
ALS Class 1E Controls: MSFIS V&V Report
- 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. The output of the software tool has been reformatted to a tabular format for ease of review.
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 is enforced.
- g. Changes in requirements are controlled through a process of approval, documentation, and verification and validation commensurate with the scope and criticality of the changes.
1/25/2009 Page 14 of29 Revision 2.5 1/25/2009 Page 14 of 29
ALS Class 1E Controls: MSFIS V&V Report
- h. Software that has been procured for use in design and/or testing shall be controlled during all phases of MSFIS development.
- i. Procedures assure configuration control, including verification that the configuration used during testing is the same as that used for the final system..
1/25/2009 Page 15 of29 Revision 2.5 1/25/2009 Page 15 of 29
ALS Class 1E 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) Design Phase
- 3) Implementation Phase
- 4) Test Phase
- 5) Installation and Checkout
- 6) 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 VVR (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 WCNOC J-105A(Q) and resolution of comments and questions deriving there from.
1/25/2009 Page 16 of29 2.5 Revision 2.5 1/25/2009 Page 16 of 29
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 were 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 input for this phase was the initial WCNOC J- 105A(Q) specification, Revision 1.
The output for this phase was the resolution of comments and issuance of Revision 2 of the WCNOC 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").
The SRD provides a structured delineation of the system requirements contained in the WCNOC 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.
Revision 2.5 1/25/2009 Page 17 of 29
ALS Class 1E Controls: MSFIS V&V Report
- e. Logic for response to detected failures.
- f. Operator interfaces (control panels, displays).
- 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 WCNOC J-105A(Q) specification, and forward to the succeeding phases of the development program.
Revision 2.5 1/25/2009 Page 18 of 29
ALS Class 1E Controls: MSFIS V&V Report 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.
3.3.2 Methods and Criteria The Requirements Traceability Matrix was updated to confirm that the complete set of WCNOC J- 105A(Q) 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 V&V 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 document 6101-00002, "MSFIS System Specification," prepared by the design team to satisfy the requirements of the WCNOC J-105A(Q) Specification. Revision 3 of WCNOC 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.

ALS Class 1E Controls: MSFIS V&V Report Design Contractor/Class 1E Controls Supplier on the ALS MSFIS project. The Qualification and Quality Oversight Contractor included a detailed report of their reviews in the final Dedication Report.
(Note: The Qualification Contractor (NI) was responsible for several aspects of the Class 1E qualification as the ALS MSFIS procurement was originally structured. The Design Contractor/Class 1E Controls Supplier (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 augmented 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 (CSI document 6101-00006)
The methods employed in the V&V of the design phase consisted principally of visual review of documents and drawings against the preceding phase outputs and the engineering 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 WCNOC specification and work properly after installation irrespective of the specification requirements.
The inputs for the V&V of the design phase were the WCNOC Specification J-105A(Q) and the MSFIS System Specification (CSI document 6101-00002). The outputs of the V&V 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. The first set of hardware included cables (cable harnesses for connecting MSFIS racks to field terminal blocks in the SA075A and SA075B cabinets), panels (Assembly panel for fusing and distribution of Class-lE 125V), ALS-boards (ALS-101, ALS-201, ALS-301, ALS-401, ALS-411, ALS-905, and backpanel), and MSFIS racks (include ALS boards and backpanel).

The ALS achieves this by implementing distributed control where no single failure will result in an untimely actuation, which in most cases results in a plant trip, or fail to perform the safety function (fail to Mounting hardware and wiring devices as necessary actuate on-demand). The distributed control is R-MSFIS.141, to mount the replacement components and achieved by having multiple autonomous boards in the R-MSFIS.142, 1.1.7 interconnect them to each other and existing circuits. 2.1-2 system each controllina a Dart of the system.
