U.S. Nuclear Regulatory Commission ND-21-0628 Enclosure Page 2 of 4 ITAAC Statement Design Commitment

4. The DAS hardware and any software are developed using a planned design process which provides for specific design documentation and reviews during the following life cycle stages:

a) Development phase for hardware and any software b) System test phase c) installation phase The planned design process also provides for the use of commercial off-the-shelf hardware and software.

Inspections/Tests/Analvses Inspection will be performed of the process used to design the hardware and any software.

Acceptance Criteria A report exists and concludes that the process defines the organizational responsibilities, activities, and configuration management controls for the following:

a) Documentation and review of hardware and any software.

b) Performance of tests and the documentation of test results during the system test phase.

c) Performance of tests and inspections during the installation phase.

The process also defines requirements for the use of commercial off-the-shelf hardware and software.

ITAAC Determination Basis An inspection was performed to verify that the Diverse Actuation System (DAS) hardware and software were developed using a planned design process which provides for specific design documentation and reviews during the following life cycle stages: Development phase for hardware and any software, system test phase, and Installation phase. The planned design process also provided for the use of commercial off-the-shelf hardware and software.

DAS was developed using defined processes, activities, and organizational responsibilities per APP-DAS-GEH-001 (Reference 1). The defined processes were further incorporated into the vendor's processes and procedures that include the software and hardware development life cycle (i.e., development phase, hardware and software requirements, design, manufacturing, factory testing, and delivery).

U.S. Nuclear Regulatory Commission ND-21-0628 Enclosure Page 3 of 4 An inspection of the vendor's processes and procedures used to develop and test the hardware and software was performed, and It was concluded that the processes define the organizational responsibilities, activities, and configuration management controls for documentation and review of hardware and any software, performance of tests and the documentation of test results during the system test phase, and requirements for the use of commercial off-the-shelf hardware and software. Technical report APP-GW-GLR-623,"AP1000 Design Certification ITAAC 2.5.01.04: Diverse Actuation System Design Process Technical Report"(Reference 2) documents the results of the Inspection and Includes references to vendor processes and procedures that define each of the Acceptance Criteria.

An Inspection of processes used for the performance of tests and Inspections during the Installation phase was performed. The results of this Inspection are documented In SV3-DAS-ITR-800519(Reference 3). DAS cabinets were Installed and Inspected In accordance with 26139-000-4MP-T81C-N3301,"Electrical Equipment Installation"(Reference 4). The DAS Is designed using the Advanced Logic System (ALS) platform. The platform Is based on Field Programmable Gate Array(FPGA)technology that does not utilize software-based controls and does not require software loading on site. Software Installation for the DAS service unit Is per SV3-GW-GCW-0125(Reference 5). Post-Installation tests are performed per the component test procedure B-GEN-ITPCI-002(Reference 6) after completion of the system energization.

The results of the above DAS Inspections conclude that the processes define the organizational responsibilities, activities, and configuration management controls for documentation and review of hardware and any software; performance of tests and the documentation of test results during the system test phase; performance of tests and Inspections during the Installation phase; and requirements for the use of commercial off-the-shelf hardware and software.

References 1 through 6 are available for NRC Inspection as part of the Unit 3 ITAAC 2.5.01.04 Completion Package (Reference 7).

ITAAC Finding Review In accordance with plant procedures for ITAAC completion. Southern Nuclear Operating Company(SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC.
