U.S. Nuclear Regulatory Commission ND-22-0262 Enclosure Page 2 of 5 ITAAC Statement Design Commitment 9.d) The PMS provides the interlock functions identified in Table 2.5.2-7.

Inspections/Tests/Anaivses An operational test of the as-built PMS will be performed using real or simulated test signals.

Acceptance Criteria Appropriate PMS output signals are generated as the interlock conditions are changed.

ITAAC Determination Basis Testing was performed to verify that the Protection and Safety Monitoring System (PMS) provides interlock functions identified in Combined License Appendix C Table 2.5.2-7 (Attachment A).

ITAAC 2.5.02.09d is completed as a combination of:

G Factory Acceptance Test -

Functional testing of interlocks G

Site software instaiiation and regression test - Hardware and software integration verification and testing of post system delivery changes The Factory Acceptance Testing (FAT) foliows the guidance of NEI 08-01 Section 9.4 (Reference 15) 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 1), PMS Test Plan APP-PMS-T5-001 (Reference 2) and applicable Codes and Standards described in Vogtie 3 and 4 Updated Final Safety Analysis Report (UFSAR) Chapter 7

(Reference 3).

The FAT included testing of PMS inputs and outputs, logic, and functionality. During this test, the initial condition for the test scenarios was established and confirmed that the interlocks actuate as appropriate for the interlocks described in Vogtie 3 and 4 UFSAR Chapter 7, Section 7.6. During the test, the process parameters were simulated and adjusted to create applicable interlock conditions, PMS outputs were monitored, and it was confirmed that the interlocks work as designed, in accordance with PMS Channel Integration Test procedures APP-PMS-T1 P-008 and APP-PMS-T1 P-009 (References 4 and 5). The results of the testing are documented in the FAT test reports APP-PMS-T2R-008 and APP-PMS-T2R-009 (References 6 and 7).

U.S. Nuclear Regulatory Commission ND-22-0262 Enclosure Page 3 of 5 Additional hardware and software installation and associated inspections and testing performed on-site to verify that the cabinets are intact and functional in accordance with Unit 3 PMS Initial Software Installation documented in SV3-PMS Cabinet Software Loading-001 (Reference 10) performed by Work Order 1123193 (Reference 8), and Cabinet Diagnostics documented in SV3-PMS-ITR-800548 (Reference 14). References 8 through 11 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) was performed for hardware changes and software changes (References 12 and 13) and determined that no additional testing is needed for the as-built system.

The completed Unit 3 FAT (References 4 through 7), Software Installation (Reference 8),

Regression test results (References 12 and 13) and Cabinet Diagnostics (Reference 14) confirm that appropriate PMS output signals are generated as the interlock conditions changed.

References 1 through 14 are available for NRC inspection as part of the ITAAC 2.5.02.09d Unit 3 Completion Package (Reference 16).

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. The ITAAC completion review is documented in the ITAAC Completion Package for ITAAC 2.5.02.09d (Reference 16) and is available for NRC review.

ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.5.02.09d performed for VEGP Unit 3 and the prescribed acceptance criteria were met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition, in accordance with approved plant programs and procedures.
