- Translation of Design Requirements and Testing Commercial-Grade Dedication
Design and Testing Requirements 6
Gutor Electronic, Wettingen, Switzerland Inspection conducted in June 2018 to assess Gutors quality activities associated with the design, fabrication, and testing of components that comprise the Uninterruptable Power Supply System for the Westinghouse AP1000 reactors being constructed at the Vogtle Units 3 and 4.
Inspection Results Gutor failed to ensure the suitability of materials, parts, equipment, and processes that are essential to the safety-related functions of the inverters being supplied to the Vogtle Units 3 and 4 nuclear power plants Gutor failed to develop acceptance criteria to ensure that the battery chargers acceptance tests meet the design requirements as stated in Westinghouse's purchase order Take-away: Suppliers need to ensure that design and testing requirements are met and document these design and testing requirements for activities affecting quality.
Design and Testing Requirements 7
Target Rock (TR) at the East Farmingdale, NY facility Inspection conducted in May 2018 to verify TRs design control and testing activities for the NuScale emergency core cooling system (ECCS)
Inspection Results TR did not provide the information for the first-of-a-kind-engineering (FOAKE) ECCS proof of concept testing as required by NuScale purchase order Also during Safety-Related testing activities TR do not establish controls to ensure the measuring and testing instrumentation used during testing activities affecting quality were adequately controlled, calibrated and adjusted at specified periods to maintain accuracy within necessary limits
Design and Testing Requirements 8
Target Rock contd Take-away: Suppliers need to meet the requirements for the design documents and the requirements for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, systems and components Suppliers should be able to demonstrate the adequacy of the design, testing and dedication through retention of auditable records providing reasonable assurance of acceptable for M&TE
Commercial-Grade Dedication 9
Flowserve Corporation, Lynchburg, VA Inspection conducted in January 2018 to assess the design, fabrication, and testing of the Limitorque motor-operated valve actuators Inspections Results Flowserve did not verify the validity of the Certificates of Conformance for hardness and tensile strengths of motor shafts material Flowserve did not maintain sufficient records for the commercially-dedicated fasteners Flowserve records lacked evidence that material testing on commercially-dedicated hardware and fasteners confirmed suitability of the parts
Commercial-Grade Dedication 10 Flowserve contd Take-away: Suppliers need to ensure that design requirements meet the procurement documents and prescribed dedication activities Suppliers should be able to demonstrate the adequacy of the design, testing and dedication through retention of auditable records providing reasonable assurance for acceptability
Commercial-Grade Dedication 11 Schulz Electric Company (SEC) New Haven, CT Inspection conducted in April 2018 to assess SECs rewinding, repair, reverse engineering and supply of safety-related motors to the nuclear industry Inspection Results SEC did not establish and implement an acceptable method to verify the material composition of shafts used in AC motors provided by a commercial supplier SEC failed to provide objective evidence to support the verification of Critical Characteristics by source evaluation and selection, objective evidence of quality furnished by the supplier, inspection at the supplier source, and/or examination of products upon delivery suppliers Take-away: Suppliers need to ensure that technical requirements are met, and ensure that any changes to dedication activities of commercial grade items are documented
12 Part 21 Evaluation and Reporting EVALUATING DEVIATIONS AND REPORTING DEFECTS AND NONCOMPLIANCE UNDER 10 CFR PART 21 13 New Regulatory Guide - RG 1.234 issued April 2018 Endorses Revision 1 of NEI 14-09, Guidelines for Implementation of 10 CFR Part 21 Reporting of Defects and Noncompliance Provides clarification on Part 21 requirements for reporting and evaluating
