3. Controls exist In the MCR to cause the components Identified In Table 2.7.4-1 to perform the listed function.

4. Displays of the parameters Identified In Table 2.7.4-1 can be retrieved In the MCR.

Inspections. Tests. Analvses Testing will be performed on the components In Table 2.7.4-1 using controls In the MCR.

Inspection will be performed for retrlevablllty of the parameters In the MCR.

Acceptance Criteria Controls In the MCR operate to cause the components listed In Table 2.7.4-1 to perform the listed functions.

The displays Identified In Table 2.7.4-1 can be retrieved In the MCR.

ITAAC Determination Basis Tests and Inspections were performed to ensure controls exist In the Main Control Room (MCR) to cause the components Identified In Combined License (COL) Table 2.7.4-1 (Attachment A) to perform the listed functions and to verify the displays of the parameters listed In Attachment A can be retrieved In the MCR.

Controls In the MCR operate to cause the components listed In Table 2.7.4-1 to perform the listed functions.

Testing was performed In accordance with the Unit 3 component test procedure listed In Reference 1 to verify controls In the MCR operate to cause the Diesel Generator Building Ventilation System (VZS) components (fans and heaters) listed In COL appendix C Table 2.7.4-1 (Attachment A) to perform the listed functions. At a MCR operator workstation, the fans listed In Attachment A were started using Plant Control System (PLS) controls from the MCR. For the heaters listed In Attachment A, the applicable heater controller was locally adjusted to above ambient temperature and the heaters were enabled using PLS controls from the MCR.

Inspections verified the fans started and heaters energized on the PLS monitor In the MCR and was documented In the test. Local verification of fan and heater status was performed during the component testing.

Unit 3 test results (Reference 1) confirmed that controls In the MCR operate to cause the components listed In Table 2.7.4-1 to perform the listed functions.

The displavs Identified In Table 2.7.4-1 can be retrieved In the MCR.

An Inspection was performed In accordance with the Unit 3 component test procedure listed In Reference 1 for VZS component Indication verifications, and visually confirmed that when each of the displays of parameters Identified In Attachment A was summoned at a MCR workstation, the summoned plant parameter appeared on a display monitor at that MCR workstation.

U.S. Nuclear Regulatory Commission ND-21-0713 Enclosure Page 3 of 4 The Unit 3 test results (Reference 1) confirmed that the VEGP Unit 3 plant parameter displays Identified In Attachment A can be retrieved In the MGR.
