DEDICATION PLAN WCN-971 5DP, REV I PAGE 4 OF 24 PURPOSE The purpose of this dedication plan is to present and define the critical characteristics and the applicable processes and standards which will be used to dedicate the commercial grade items described in the "Device Descriptions" section of this document.

This dedication plan addresses critical characteristics primarily. Additional testing and verification, beyond that required for dedication of the units described in the "Device Descriptions" section of this document, will be performed (as applicable) to ensure items purchased through Nuthermn International are the items described in the customers specification sheets and/or Purchase Order.

All qualification work is accomplished in accordance with customer purchase order and specification requirements, Nuclear Regulatory Commission Guidelines, and applicable Institute of Electrical and Electronic Engineers Standards.

DEDICATION PLAN WCN-9715DP, REV I PAGE 5 OF 24

• EPRI TR-106439 - "Guideline on Evaluation and Acceptance of Commercial Grade Digital Equipment of Nuclear Safety Applications" DEVICE DESCRIPTION The Main Steam and Feedwater Isolation System (MSFIS) has two distinct functions:

• Steam Line Isolation System (SLIS) - Main Steam Line Isolation minimizes the uncontrolled cool down of the Reactor Coolant System (RCS) that would result from a main steam line rupture. Input signals pass from the detectors through the Solid State Protection System (SSPS) to the MSFIS cabinet where the output signal is generated.

" Feedwater Isolation System (EWIS) - Feedwater isolation minimizes the potential for excessive post-trip cool down of the RCS due to overfilling the steam generators. It also prevents moisture carryover caused by high steam generator levels, and isolates normal Feedwater in the event of a high Energy Line Break inside containment.

MSFIS will include a safety-related logic-controller-based system to performn the control functions of the Main Steam Isolation Valves (MSIVs) and Main Feedwater Isolation Valves (MFIVs) with system-medium actuators. The MSFIS System has two redundant subsystems located in separate cabinets:

MSFIS Channel 1 (1) located in MSFIS Cabinet SA075A (Train A)

MSFIS Channel IV (4) located in MSFIS Cabinet SA075B (Train B)

Each MSFIS cabinet is capable of supplying the control logic outputs required for operating each of the 4 Main Steam Isolation Valves and 4 Main Feedwater Isolation Valves.

Dedication activities will be performed by Nutherm International Inc. on the control system ALS Racks and Assembly Panels for Channels I and IV.

DEDICATION DESCRIPTION GENERAL The dedication process, per EPRI Report 5652, assumes that "the design requirements of the item have been satisfactorily translated into specification requirements as reflected in the procurement document." The guideline goes on to describe three fundamental issues which, once addressed, provide a foundation for the acceptance process of a particular item. The three fundamental issues as described in EPRI Report 5652 are as follows:

501 South I Ph Street PHONE: 618-244-6000 INTRNAIONL, NC.Mt.

Vernon IL 62864 FAX: 618-244-6641

DEDICATION PLAN WCN-9715DP, REV 1 PAGE 6 OF 24

" Determine the safety function of the item

• Confirm the item is commercial grade

• Identify critical characteristics.

These three fundamental issues are addressed during the technical review process and a Component Dedication Planner (CDP) is generated for each item to be dedicated. In the case of more complex systems such as the MSFIS system a Critical Characteristic Matrix is used to quantify Critical Characteristics and the Verification methods used. The Critical Characteristic Matrix for the replacement MSFIS system has been incorporated into this Dedication Plan.

EPRI NP-5 652 is used as a guideline for the dedication process of commercial grade items. As stated in section 1.3.4, 'the methods in the guideline are in conformance with existing regulatory requirements. The methods for accepting commercial grade items are consistent with the provisions of Criterion VII of Appendix B to I OCFR50 which states:

"Measures shall be established to assure that purchased material, equipment, and services, whether purchased. directly or through contractors and subcontractors, conform to the procurement documents.

These measures shall include provisions, as appropriate, for source evaluation and selection, objective evidence of quality fturnished by the contractor or subcontractor, inspection at the contractor or subcontractor, inspection at the contractor or subcontractor source, and examination of products upon delivery."

Nutherm International has incorporated the guideline into its QA program and in-place procedures for the dedication of commercial grade items. See Figure 1 for a block diagram of the generic dedication process. The methods referred to (Method 1 thru 4) are described in detail in EPRI NP-5652. Nutherm International employs a combination of method 1 and other acceptance methods. Figure 2 is a schematic logic diagram for employing method 1, taken from EPRI NP-S 652. Though not all inclusive, the diagram provides a general feel for the dedication process using this method.

MSFIS REPLACEMENT SYSTEM The critical characteristics are divided into three general categories; Product Information, Physical Attributes, and Performance. EPRI TR-106439 incorporated Product Information in the Physical Attributes categories and added Dependability. Though the MSFIS system is not software based, many of the critical characteristics and dedication activities described in EPRI TR-106439 are applicable and have been incorporated into this Dedication Plan. The critical characteristics of this system are varied enough that all four acceptance methods will be used to verify acceptability. For newer, more complex systems this is not unusual. System and other experts will be used, as applicable, to provide any necessary technical expertise throughout the dedication process. 1IOCFR21 states:

DEDICATION PLAN WCN-9715DP, REV 1 PAGE 7 OF 24 "dedication is an acceptance process undertaken to provide reasonable assurance that a commercial grade item to be used as a basic component will perform its intended safety function and, in this respect, is deemed equivalent to an item designed and manufactured under a 10 CFR Part 50, appendix B, quality assurance program. This assurance is achieved by identifying the critical characteristics of the item and verifying their acceptability by inspections, tests, or analyses" As previously stated, a Critical Characteristics Matrix was developed as part of the dedication process. This matrix lists each Critical Characteristic along with its Acceptance Criteria. For each characteristic the matrix also lists the Validation Document(s) and Validation Method(s) which will be used in the dedication process.

Following the matrix a more detailed explanation of each characteristic category and applicable characteristics is included. EPRI TR-106439, 1996, "Guideline on Evaluation and Acceptance of Commercial Grade Digital Equipment for Nuclear Safety Applications", section 4.2 "Guidance on Defining and Verifying Critical Characteristics",

states:

"Translation of design requirements into critical characteristics for a commercial grade item is a key element in the dedication process. It is the link between the technical evaluation, which defines requirements, including hardware, software, human-machine interface, quality and reliability requirements, is an important prerequisite for dedication of a commercial grade item."

A thorough review of Wolf Creek Generating Station Specification J-1 05A(Q), was performed to generate the Critical Characteristics Matrix, with Acceptance Criteria directly linked to Specification requirements, as applicable.

DEDICATION PLAN WCN-9715DP, REV 1 PAGE 18 OF 24 PHYSICAL CHARACTERISTICS Physical characteristics are those characteristics of the item that deal with its construction, materials, shape, form and fit, etc. The critical characteristics classified as physical attributes are determined during the Technical Review and listed on the Critical Characteristics Matrix. The Project Manager evaluates critical physical attributes based on the item's safety function and determines the best method to verify them. Typically, for dedication, these characteristics are compared with a tested item in the Nutherm International, Inc. Test Specimen Library. The comparison is documented, then reviewed and evaluated by the Nutherm Engineering department. Any differences between the tested item and the dedicated item are evaluated with respect to the level that the item is being dedicated to (e.g. Seismic, Mild Environment) and documented either on the Comparison sheet or a Record of Dedication. Through the comparison process, reasonable assurance is gained of the physical similarity between the item to be dedicated and the item previously tested.

MSFIS System critical physical characteristics are listed above. Similarity will be established to the qualified part as well as design documents during the dedication process, with any differences noted and evaluated for impact on qualification by Nutherm Engineering Department.

Product information verification is required to provide reasonable assurance that the item ordered is in fact the item received, as is part of the Physical Characteristic category of Critical Characteristic. This portion of the dedication process includes, but is not limited to, Part Number/Model Number verification and Manufacturer verification. Product information verification is performed and documented at receipt inspection in accordance with Nutherm International, Inc. Quality Assurance Manual No.: QA-N-1 0179-5 and the applicable approved procedures. Section 1.3.3 of EPRI NP-5 652 states; "Part number verification is an integral step in the acceptance of commercial grade items and is included in each of the four acceptance methods.

Verification of a part number and the utilization of the acceptance methods in this guideline provide assurance of acceptability.

Since suppliers furnish commercial grade items for general industrial use, they may change the product design or the manufacturing process, and not the part number. These actions are taken without concern for the nuclear end user's design requirements. The methods described in this guideline provide various means to accept a commercial grade item without sole reliance upon part number verification."

Because of possible changes by the manufacturer, Product Information alone is an insufficient basis for acceptance of commercial grade items for nuclear safety related applications. This is especially true of complex digital equipment. By combining Product Information verification with the applicable testing, comparisons, etc. of an item's Physical Attributes, Performance characteristics, and Dependability characteristics reasonable assurance of acceptability can be achieved.

DEDICATION PLAN WCN-9715DP, REV 1 PAGE 19 OF 24 Each cabinet of the MSFIS System contains the following which will be verified during the dedication process:

• 2 ALS Control System Racks; one Main Steam (MS) rack and one identical Feed Water (FW) rack. Each Rack contains the following boards:

o 1 Core Logic board (CLB) o 2 Digital Input boards (IPB) o 1 Solid-State Output board (SOB) o 3 Solid State FET & Sensor Output boards (FSB) o 1 Service & Test board (STB) o 2 Redundant Power Supply Modules (PSU)

• 1 Assembly panel, with MS and FW components as follows:

o 125V Terminal and Distribution Block o

125V Fuse Blocks for Solenoid Outputs o

125V Fuse Block and Suppression Filter to Power Supplies In addition to Nutherm's normal receipt and visual inspection procedures, each board of each rack will be subject to visual inspection in accordance with Nutherm Procedure TPS-9062, Rev. 0 "ALS Rack Component Verification"'. Each board revision and part number will be recorded along with any other distinguishing marks such as lot numbers, date codes, etc. Software Revision Number for the FPGA logic will be recorded and verified against design documents. Each component on every board will be compared to the manufacturer Bill of Materials (BOM) and Board Layout drawings, as applicable, with any discrepancies noted and addressed in the Dedication Report. Quality of workmanship, such as soldering and overall construction, will be compared with the quality of the qualification unit with any discrepancies noted and addressed in the Dedication Report.

Component verification against design documents, BOM, and Board Layout drawings provides objective evidence that design control by the manufacturer has been implemented.

PERFORMANCE The Performance section of the dedication plan lists the operational cri tical characteristics determined during the technical evaluation. Performance characteristics are verified through testing, analysis, or, in the case of UL listings, comparison with 501 South 11Wt Street PHONE: 618-244-6000 INUtERAINAIC Mt.

All testing at the Nutherm Test Laboratory is performed by technicians Certified Level II (minimum) in accordance with ANSI N45.2.6 and the requirements of the Nutherm Quality Assurance Program. All quantitative data is taken using measuring and test equipment (M&TE) which is calibrated under the Nutherm Quality Assurance Program, by calibration facilities which operate under Nutherm approved 10CFR5O, Appendix B Quality Assurance programs. Standards used in performance of calibration are traceable to NIST. When no national standards exist, the basis for calibration is otherwise documented. In all cases, the accuracy of the M&TE used is equal to or greater than the accuracy requirement specified by the engineering department for the test. The description of the test equipment used is presented on the test data sheets.

Performance testing will be performed on the MSFIS systems to verify proper operation and compliance with the applicable sections of Wolf Creek specification J-105A. A Final Acceptance Test (FAT), TPS-9064, will be performed on the supplied MSFJS control system. A detailed test procedure for FAT testing has been developed by Nutherm in cooperation with CS Innovations, for approval by Wolf Creek prior to the start of testing.

The test procedure was developed based on design documents from CS Innovations as well as WC specification requirements. Actual system response to stimulus is compared to designed response as delineated in design documents through Acceptance Criteria. As part of the FAT abnormal conditions and events testing will be performed to verify proper system response to abnormal conditions.

In addition to verifying the performance critical characteristics, thorough testing of the supplied equipment provides objective evidence of design control and built-in quality, adding to the reasonable assurance that the dedicated equipment is suitable for the specified safety related application.

DEPENDABILITY The Dependability category of critical characteristics is described in detail in EPRI TR-106439. These characteristics are difficult to verify through testing and inspection alone.

Because built-in features can have a significant impact on the robustness of electronic devices, dedication activities will continue throughout the design and prototype phases following the life cycle approach. Various verification and validation steps with appropriate documentation will be performed at the different phases of the life cycle as described in the Critical Characteristics Matrix. To gain reasonable assurance in the dependability of the MSFIS system, a combination of inspections, vendor process reviews, verification and validation steps, and product development and documentation review will be used to verify the critical characteristics listed in this plan.

DEDICATION PLAN WCN-9715DP, REV I PAGE 21 OF 24 The following steps will be taken to verify the built-in quality critical characteristics:

" An initial Commercial Grade Survey was performed at CS Innovations (CSI).

Follow-up surveys and source inspections will be performed to verify continued compliance with the CSI QA program.

• A source inspection will be performed to provide objective evidence that the CSI QA program was applied to the production of the dedicated items.

" A System Reliability Analysis (SKA) was performed under the Wolf Creek (WC)

Quality Assurance program. The SRA report will be reviewed and approved by qualified WC personnel and included in the final Dedication Package. WC will provide documentation and attestation that the SRA critical characteristic has been adequately verified.

• Surveys and source inspections, as required, will be performed to verify that CSI QA program was applied to the hardware design. The CSI process follows the recommendations of DO-254, "Design Assurance Guidance for Airborne Electronic Hardware". DO-254 describes in detail the Hardware Design Life Cycle and the data which will be developed as evidence of compliance. The surveys and inspections will provide assurance that this process was followed and the appropriate data is available.

" Surveys and source inspections, as required, will be performed to verify that CSI implements appropriate configuration control. The processes and procedures used by the manufacturer will be evaluated. In particular, version control of FPGA design files and design tools will be verified. Design documents will be verified against delivered equipment as fur-ther objective evidence that design control was implemented. The other aspects of configuration control which will be verified include; documented plans and procedures, baseline maintenance, change control, and error reporting processes.

• Selection of the FPGA and design tools was documented. Said documentation will be included in the final Dedication Report.

" A Failure Modes and Effects (FMEA) analysis was performed under the WC QA program. The FMEA report will be reviewed and approved by qualified WC personnel and included in the final Dedication Package. WC will provide documentation and attestation that the FMEA critical characteristic has been adequately verified.

• Problem reporting is incorporated in the Nutherm Quality Assurance Manual.

Surveys and source inspections, as required, will be performed to verify that CSI has error-reporting procedures. Conformance to such procedures will be verified.

DEDICATION PLAN WCN-9715DP, REV I PAGE 22 OF 24 VERIFICATION AND VALIDATION Verification and Validation performed by Nuthermn will involve several steps-and processes. Quality Control Inspections (QCI) in accordance with Nutherm procedures will be performed on the production items. These inspections will include Visual Inspections, Point to Point Continuity Verification, Verification of Specified Parts, as well as a detailed inspection and comparison of board components, BOM's, and board layout drawings. A Final Acceptance Test will be performed in accordance with an approved procedure to verify' conformance to purchase order and specification requirements. The Critical Characteristics Matrix lists the performance characteristics which will be verified through testing.

DO-254, "Design Assurance Guidance for Airborne Electronic Hardware", contains detailed requirements for Verification and Validation. Surveys and source inspections will be performed, as required, to verify that the CSI V&V processes, plans, and implementation conform with the requirements of DO-254.
