iii) For each test of a control listed in Table 2.5.4-1 with a "Yes" in the "Control" column, an actuation signal is generated. Tests from the actuation signal to the actuated device(s) are performed as part of the system-related inspection, test, analysis and acceptance criteria.

ITAAC Completion Description Multiple ITAAC are performed to verify that the Data Display and Processing System (DDS) provides for the minimum inventory of displays, visual alerts, and fixed position controls, as identified in COL Appendix C Table 2.5.4-1 (Attachment A), the plant parameters listed with a "Yes" in the "Display" column and visual alerts listed with a "Yes" in the "Alert" column can be retrieved at the Remote Shutdown Workstation (RSW), and the controls listed with a "Yes" in the "Control" column are provided at the RSW. The subject ITAAC performs inspections on the displays in Attachment A to verify the listed plant parameters can be retrieved at the RSW, inspections and testing of the alerts in Attachment A to verify that the listed plant parameters are used to generate visual alerts that identify challenges to critical safety functions, and testing of the controls listed in Attachment A to verify the listed controls generate actuation signals.

The plant parameters listed in Table 2.5.4-1 with a "Yes" in the "Displav" column can be retrieved at the RSW.

An inspection is performed to verify the retrievability of the VEGP Unit 3 and Unit 4 plant parameters at the RSW. The inspection for retrievability confirms that the plant parameters listed in Attachment A with a "Yes" In the "Display" column can be retrieved at the RSW.

U.S. Nuclear Regulatory Commission ND-19-1571 Enclosure Page 3 of 9 The inspection is performed in accordance with 3-DDS-ITPP-520 and 4-DDS-ITPP-520 (Reference 1 and 2)and visually confirms that when each of the plant parameters identified in Attachment A with a "Yes" in the "Display" column is recalled at the RSW,the recalled plant parameter appears on a display monitor.

The inspection results are included in References 1 and 2 and confirm that the plant parameters listed in Table 2.5.4-1 with a "Yes" in the "Display" column can be retrieved at the RSW.

References 1 and 2 are available for NRG inspection as part of the Unit 3 and Unit 4 ITAAC 2.5.04.02.1 Completion Packages(References 30 and 31).

The plant parameters listed in Table 2.5.4-1 with a "Yes" in the "Alert" column are used to Generate visual alerts that identifv challenges to critical safetv functions. The visual alerts actuate in accordance with their logic and values.

Inspections and testing are performed to verify the retrievability of the VEGP Unit 3 and Unit 4 visual alerts at the RSW. The inspections and testing confirm that the plant parameters listed in Attachment A with a "Yes" in the "Alert" column are used to generate visual alerts that identify challenges to critical safety functions(CSF)and actuate in accordance with their logic and values.

This ITAAC is completed as a combination of;

• PMS Factory Acceptance Test(FAT)- Functional testing of PMS inputs, outputs, logic, and function

• Site software installation and regression test - Hardware and software integration verification and testing of post system delivery changes.

• Preoperational Test of communication - Functional testing of the communication between the PMS output and the DDS input

• DDS FAT- Functional testing of DDS inputs, outputs, logic, and function Preoperational Test of the as-built RSW - Visual inspection and test of the visual alerts at the as-built RSW The PMS FAT was performed in accordance with PMS Software Program Manual WCAP-16096 (Reference 3), PMS Test Plan APP-PMS-T5-001 (Reference 4)and applicable Codes and Standards described in Vogtle 3 and 4 UFSAR Chapter 7(Reference 33). The DDS FAT was performed in accordance with PLS Test Plan APP-PLS-T5-001 (Reference 5).

The logic that generates the visual alerts is contained in both the Qualified Data Processing System (QDPS)of the PMS and the Nuclear Applications Programs(NAPs)of the DDS and are tested as follows:

• Logic and values of visual alerts generated in the QDPS are verified in the PMS FAT

• Logic and values of visual alerts generated in the NAPs are verified in the DDS FAT

U.S. Nuclear Regulatory Commission ND-19-1571 Enclosure Page 4 of 9 During the FAT, the plant parameters were simulated and adjusted to create applicable alert conditions. RMS outputs were monitored, and It was confirmed that the visual alerts actuate In accordance with their correct logic and values. This testing was performed In accordance with FAT Test Procedure APP-PMS-T1P-010(Reference 6). The results of the PMS testing are documented In the FAT test reports APP-PMS-T2R-010(Reference 7). The FAT results confirm that the PMS Inputs and outputs, logic and Installed software function correctly to provide for the visual alerts, as Identified In Attachment A.

Additional hardware and software Installation and associated Inspections and testing are performed on-slte to verify that the cabinets are Intact and functional In accordance with Units 3 and 4 for applicable Field Change Notifications(FCNs)AP1000 Vogtle Unit 3 PMS Initial Software Installation - Software Release 8.7.0.1 and API000 Vogtle Unit 4 PMS Initial Software Installation - Software Release 8.7.0.1 and B-GEN-ITPCI-001 (References 22, 23, and 34).

References 22, 23, and 34 Include steps that confirm and document successful software load and further confirm the physical properties of the as-bullt PMS. A regression analysis (I.e.,

change evaluation) Is performed post-delivery for hardware changes(References 27 and 28) and software changes(References 29, 35, and 36) If additional testing Is needed for the as-bullt system.

To provide communication between the PMS and DOS, the Maintenance and Test Panel(MTP)

In a given PMS division provides an Isolated (optlcal-to-electrlcal Isolation) pathway from the Intra-dlvlslonal communication bus to the Advant/Ovatlon Interface (AOI) Gateway associated with that division. Over the divisional AOI Gateway, the MTP transfers certain real-time data from the division's AF100 bus to the non-safety Real Time Data Network to support control and Information system functions performed In non-safety systems, such as the DDS. Testing In 3-PMS-ITPP-521 and 4-PMS-ITPP-521 (References 8 and 9) verifies the AOI gateway by ensuring datapolnts on PMS which are output to the DDS match those on the DDS.

During the DDS FAT, Inputs to the DDS were simulated and adjusted to create applicable alert conditions and It was confirmed that the logic and functionality of the DDS supports the visual alerts. This testing was performed In accordance with FAT Test Procedures APP-DDS-T1P-001 and APP-PCS-T1P-100(References 10 and 11). The results of the testing are documented In the FAT test reports APP-DDS-T1R-001 and APP-PCS-T2R-100(References 12 and 13).

Testing Is performed In accordance with 3-DDS-ITPP-520 and 4-DDS-ITPP-520 (References 1 and 2)to verify that when the applicable DDS Input Is simulated, each plant parameter listed In Attachment A with a "Yes" In the "Alert" column Is used to generate visual alerts that Identify challenges to CSF at the RSW. Testing In References 1 and 2 forces the applicable DDS input parameter from an engineering workstation and visually confirms that when each of the plant parameters Identified In Attachment A with a "Yes" In the "Alert" column Is used to generate visual alerts that Identify challenges to CSF,the summoned plant visual alert appears on a display monitor at the RSW.

The completed Unit 3 and Unit 4 factory test results (References 7, 12, and 13), FCNs (References 22, 23, and 34), regression test results (References 27, 28, 29, 35, and 36), and preoperatlonal test results (References 1, 2, 8, and 9) confirm that the plant parameters listed In Table 2.5.4-1 with a "Yes" In the "Alert" column are used to generate visual alerts that Identify challenges to critical safety functions. The visual alerts actuate In accordance with their logic and values.

U.S. Nuclear Regulatory Commission ND-19-1571 Enclosure Page 5 of 9 References 1, 2, 7 through 9,12, 13, 22, 23, 27 through 29 and 34 through 36 are available for NRG inspection as part of the Unit 3 and Unit 4 ITAAC 2.5.04.02.i Completion Packages (References 30 and 31).

For each test of a control listed in Table 2.5.4-1 with a "Yes" in the "Control" column, an actuation sional is oenerated. Tests from the actuation signal to the actuated device(s) are performed as part of the svstem-related inspection, test, analysis and acceptance criteria.

An operational test of the as-built system is performed using each RSW control. The test confirms that for each test of a control listed in Table 2.5.4-1 (Attachment A) with a "Yes" in the "Control" column, an actuation signal is generated. Tests from the actuation signal to the actuated device(s) are performed as part of the system-related inspection, test, analysis and acceptance criteria.

This ITAAC is completed as a combination of:

• Factory Acceptance Test- Functional testing of the PMS control circuit

• Site software installation and regression test - Hardware and software integration verification and testing of post system delivery changes

• Component test-testing of the remote shutdown room switches, including their interface with PMS and full testing of the hydrogen igniter soft controls at the RSW The Factory Acceptance Testing (FAT)follows the guidance of NEI 08-01 Section 9.4 (Reference 32)for the as-built tests to be performed at other than the final installed location.

The FAT was performed in accordance with PMS Software Program Manual WCAP-16096 (Reference 3), PMS Test Plan APP-PMS-T5-001 (Reference 4), and applicable Codes and Standards described in Vogtle 3 and 4 UFSAR Chapter 7(Reference 33).

The FAT included testing of PMS inputs and outputs, logic, and functionality. During this test, the manual inputs to the PMS were simulated and it was confirmed that the actuation signals were generated for the minimum inventory of controls at the RSW identified in Attachment A.

This testing was performed in accordance with the PMS FAT procedures APP-PMS-T1P-007 and APP-PMS-T1P-008(References 14 and 15). The results of the tests are documented in the FAT test reports SVO/SV3/SV4-PMS-T2R-007 and SV0/SV3/SV4-PMS-T2R-008 (References 16 through 21).

References 22, 23, and 34 include steps that confirm and document successful software load and further confirm the physical properties of the as-built PMS. A regression analysis (i.e.,

change evaluation) is performed post-delivery for hardware changes (References 27 and 28) and software changes(Reference 29, 35, and 36) if additional testing is needed for the as-built system.

U.S. Nuclear Regulatory Commission ND-19-1571 Enclosure Page 6 of 9 Component testing of the dedicated RSW controls identified in Attachment A is performed in accordance with component test packages SNCXXXXXX (Unit 3) and SNCYYYYYY (Unit 4)

(References 24 and 25). These component test packages utilize B-GEN-ITPCI-006,(Reference 26)to test the RSW manual controls. Selected RSW manual controls are actuated and PMS inputs are confirmed by visually inspecting the digital input light emitting diodes. The completed Unit 3 and Unit 4 component test packages confirm that select RSW manual control actuations are received at the PMS.

For the containment hydrogen igniters, testing is performed in accordance with 3-DDS-ITPP-520 and 4-DDS-ITPP-520(References 1 and 2). Testing in References 1 and 2 verifies the Hydrogen Control System (VLS) is available then the containment hydrogen igniters are energized using soft controls from the RSW. Local voltage verification at the igniter control relays verifies the hydrogen igniter soft controls generate an actuation signal and is documented in the test.

The completed Unit 3 and Unit 4 FAT results (References 16 through 21), FCNs (References 22, 23, and 34), regression test results (References 27, 28, 29, 35, and 36), completed component test packages (References 24 and 25), and preoperational test results (References 1 and 2) confirm that for each test of a control listed in Table 2.5.4-1 with a "Yes" in the "Control" column, an actuation signal is generated.
