14. Controls exist in the MCR to cause the components identified in Table 2.1.2-3 to perform the listed function.

Inspections. Tests. Analyses Testing will be performed on the components in Table 2.1.2-3 using controls in the MCR.

Acceptance Criteria Controls in the MCR operate to cause the components listed in Table 2.1.2-3 to perform the listed functions.

ITAAC Determination Basis Testing was performed in accordance with Unit 3 Initial Test Program (ITP) Work Order(WO)

SV3-RCS-T0W-1248486 (Reference 1) to verify that controls exist in the Main Control Room (MCR)to cause the components identified in Combined License(COL) Appendix C Table 2.1.2-3(Attachment A)to perform the listed function.

The individual heater groups for each bank of heaters were tested to verify proper operation utilizing the Plant Control System (PLS). Testing was coordinated and performed during Unit 3 Hot Functional Testing. The MCR pressurizer heater On/Off control function was verified to control each pressurizer heater group using MCR pressurizer heater group current indication, as the pressurizer heater groups were cycled on and off.

The report documenting the Unit 3 test results, ITAAC Technical Report SV3-RCS-ITR-800066 (Reference 2), confirmed that controls in the MCR operate to cause the components listed in Attachment A to perform the listed functions.
