U.S. Nuclear Regulatory Commission ND-19-1437 Enclosure Page 2 of 4 ITAAC Statement Design Commitment

11. The RMS hardware and software Is developed using a planned design process which provides for specific design documentation and reviews during the following life cycle stages:

a) Not used b) System definition phase c) Hardware and software development phase, consisting of hardware and software design and Implementation d) System Integration and test phase e) Installation phase Inspectlons/Tests/Analvses Inspection will be performed of the process used to design the hardware and software.

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

a) Not used.

b) Specification of functional requirements.

c) Documentation and review of hardware and software.

d) Performance of system tests and the documentation of system test results. Including a response time test performed under maximum CPU loading to demonstrate that the PMS can fulfill Its response time criteria.

e) Performance of Installation tests and Inspections.

ITAAC Determination Basis An Inspection was performed to verify that the Protection and Safety Monitoring System (PMS) hardware and software were developed using a planned design process that provided for specific design documentation and reviews during the following life cycle stages: System definition phase, hardware and software development phase (consisting of hardware and software design and Implementation), system Integration and test phase, and Installation phase.

PMS was developed by the vendor using defined processes, activities and organizational responsibilities per WCAP-16096-P-A (Reference 1) as supplemented by WCAP-15927-P (Reference 2). The defined processes were further Incorporated Into the vendor's processes and procedures that Include the software and hardware development life cycle (I.e.,

requirements, design, manufacturing, factory testing. Independent verification and validation, and delivery).

U.S. Nuclear Regulatory Commission ND-19-1437 Enclosure Page 3 of 4 An inspection of the vendor's processes and procedures used to design the hardware and software was performed, and it was concluded that the processes define the organizational responsibilities, activities, and configuration management controls for specification of functional requirements, documentation, and review of hardware and software, and performance of system tests and the documentation of system test results, including a response time test performed under maximum Central Processing Unit(CPU)loading to demonstrate that the PMS fulfills its response time criteria. Technical report APP-GW-GLR-620"API000 Design Certification ITAAC 2.5.02.11: Protection and Safety Monitoring System Design Process Technical Report"(Reference 3)documented the results of the inspection and included references to vendor processes and procedures that define each of the Acceptance Criteria.

An inspection of processes used for the performance of installation tests and inspections was performed. The results of this inspection were documented in Reference 4. Hardware (e.g.,

PMS cabinets) was installed and inspected in accordance with 26139-000-4MP-T81C-N3301, "Electrical Equipment Installation" (Reference 5). Software installation and regression analysis were per SV3-GW-GCW-300(Reference 6). Energization and post-installation tests were performed per the component test procedure B-GEN-ITPCI-001 (Reference 7).

The results of the above PMS inspections concluded that the process defined the organizational responsibilities, activities, and configuration management controls for the following: specification of functional requirements, documentation, and review of hardware and software, performance of system tests and the documentation of system test results, including a response time test performed under maximum CPU loading to demonstrate that the PMS fulfills its response time criteria and performance of installation tests and inspections.
