U.S. Nuclear Regulatory Commission ND-23-0417 Enclosure Page 4 of 16 ITAAC Determination Basis Multiple ITAAC were performed to verify by inspections and tests that each of the Chemical and Volume Control System (CVS) makeup pumps provide a flow rate of greater than or equal to 100 gpm to the Reactor Coolant System (RCS) and provides spray flow to the pressurizer. This ITAAC also ensures safety-related displays identified in Combined License (COL) Table 2.3.2-1 can be retrieved in the Main Control Room (MCR), displays identified in COL Table 2.3.2-3 can be retrieved in the MCR, controls in the MCR operate to cause the remotely operated valves identified in COL Table 2.3.2-1 to perform active functions, controls in the MCR cause pumps identified in COL Table 2.3.2-3 to perform the listed function, and the pumps identified in COL Table 2.3.2-3 start after a signal is generated by the Plant Control System (PLS). Additionally, this ITAAC verifies the valves identified in COL Table 2.3.2-1 as having Protection and Safety Monitoring System (PMS) control perform the active function identified in the table after receiving a signal from the PMS, valves close within the following times after receipt of an actuation signal: V090, V091 < 30 sec; V136A, V136B < 20 sec, each motor-operated valve and check valve change positions as indicated in COL Table 2.3.2-1 under preoperational test conditions. Upon loss of motive power, each remotely operated valve identified in COL Table 2.3.2-1 assumes the loss of motive power position.

i) Each CVS makeup pump provides a flow rate of greater than or equal to 100 gpm.

Testing was performed in accordance with Unit 4 pre-operational test procedure listed in SV4-CVS-ITR-800301 (Reference 1) to confirm that with suction aligned to the boric acid storage tank, the Reactor Coolant System (RCS) at greater than or equal to 2000 psia and a flow path established to the RCS, that each CVS makeup pump provides greater than or equal to 100 gpm flow rate measured at the pump discharge.

With the RCS at 555°F - 559°F and 2220 psig - 2250 psig, the CVS system was aligned to perform a boron addition to the RCS. The A CVS makeup pump suction was aligned to the boric acid storage tank and a boron addition was initiated using the operating procedure. The flow rate on the discharge line of the A CVS makeup pump was monitored and trended. This testing was repeated utilizing the B CVS makeup pump. The Unit 4 A CVS makeup pump flow rate was 106.837 gpm and the Unit 4 B CVS makeup pump flow rate was 106.893 gpm.

The completed test results (Reference 1) confirmed that each CVS makeup pump provides a flow rate of greater than or equal to 100 gpm with the RCS at greater than or equal to 2000 psia.

Each CVS makeup pump provides spray flow to the pressurizer.

Testing was performed in accordance with Unit 4 pre-operational test procedure listed in SV4-CVS-ITR-800301 (Reference 1) to confirm that with suction aligned to the boric acid storage tank, the Reactor Coolant System (RCS) at greater than or equal to 2000 psia and a flow path established to the pressurizer auxiliary spray, that each CVS makeup pump provides spray flow to the pressurizer.

With the RCS at 555°F - 559°F degrees and 2220 psig - 2250 psig, the CVS system was aligned to provide make-up to the RCS. The makeup flow control valve was placed in manual, suction was aligned to the boric acid storage tank, and the A CVS makeup pump was started.

The auxiliary spray valve was opened, and the makeup flow control valve was throttled open until flow was established. The discharge flow rate was monitored and trended. The B CVS makeup pump was started, and the A CVS makeup pump was stopped. The makeup flow

U.S. Nuclear Regulatory Commission ND-23-0417 Enclosure Page 5 of 16 control valve was throttled to provide flow at the pump discharge and the flow rate was monitored and trended.

The completed test results (Reference 1) confirmed that each CVS makeup pump provides spray flow to the pressurizer with the RCS at greater than or equal to 2000 psia.

Safety-related displays identified in Table 2.3.2-1 can be retrieved in the MCR.

An inspection was performed as documented in SV4-CVS-ITR-801301 (Reference 2) to ensure the safety-related displays identified in Combined License (COL) Table 2.3.2-1 (Attachment A) can be retrieved in the MCR.

The valves listed in Attachment A as having safety-related displays for valve position are located on the MCR PMS Visual Display Units (VDUs) and verified to indicate on each of the VDUs.

The completed inspection results (Reference 2) confirmed that safety-related displays identified in Table 2.3.2-1 can be retrieved in Unit 4 MCR.

Controls in the MCR operate to cause the remotely operated valves identified in Table 2.3.2-1 to perform active functions.

Stroke testing was performed in accordance with Unit 4 component test work package listed in SV4-CVS-ITR-804301 (Reference 5) using controls in the MCR to confirm that the remotely operated valves identified in COL Table 2.3.2-1 (Attachment B) perform their active function.

The valves identified in Attachment B were stroke tested using an operator workstation in the MCR. The valves were initially opened and were stroked closed using the Plant Control System (PLS) and verified locally to have closed.

The completed test results (Reference 5) confirmed that controls in Unit 4 MCR operate to cause the remotely operated valves identified in Table 2.3.2-1 to perform active functions.

i) The valves identified in Table 2.3.2-1 as having PMS control perform the active function identified in the table after receiving a signal from the PMS.

Testing was performed in accordance with Unit 4 component test procedures listed in SV4-CVS-ITR-802301 (Reference 3). These component test packages confirm that the valves identified in Table 2.3.2-1 (Attachment C) as having PMS control perform the active function identified in the table after receiving a signal from the PMS.

The component test packages in Reference 3 established initial conditions with each valve verified locally and in the MCR to be in the open position. An actuation signal was generated by PMS using the PMS Maintenance and Test Panel (MTP) to generate a signal to close the valves in Attachment C. Each valve was verified locally and in the MCR to be closed.

The completed test results (Reference 3) demonstrated that the valves identified in Table 2.3.2-1 as having PMS control perform the active function identified in the table after receiving a signal from the PMS.

Testing was performed using the component test packages in reference 3 and positioned the valves to the open position. An actuation signal was generated by PMS using the PMS Maintenance and Test Panel (MTP) to generate a signal to close the valves and the valves were verified locally and in the MCR to be closed. The valve closure times are listed in Attachment D.

The completed test results (Reference 3) demonstrated that the Unit 4 valves close within the following times after receipt of an actuation signal: V090, V091 < 30 sec, V136A/B < 20 sec.

iii) Each motor-operated valve changes position as indicated in Table 2.3.2-1 under pre-operational test conditions.

Testing was performed in accordance with Unit 4 pre-operational test procedure listed in SV4-CVS-ITR-800301 (Reference 1) to confirm the motor-operated valves listed in COL Appendix C Table 2.3.2-1 (Attachment E) change position under pre-operational flow, differential pressure, and temperature conditions.

Testing established the pre-operational test conditions of RCS at atmospheric pressure and ambient temperature and ensured the RCS makeup rate was greater than or equal to 135 gpm and less than or equal to 175 gpm which provided the greatest differential pressure for makeup line Motor-operated Valve (MOV) operation. CVS-PL-V090 was closed and verified to be closed locally and then reopened. The pre-operational test conditions were re-verified and CVS-PL-V091 was closed and verified to be closed locally.

Pre-operational test conditions were established with the RCS at 555°F - 559°F degrees and 2220 psig - 2250 psig with purification in service at normal operating temperature and pressure.

CVS-PL-V001 was closed and verified to be closed locally and then CVS-PL-V001 was re-opened. Pre-operational test conditions were re-verified and CVS-PL-V002 was closed and verified to be closed locally, then CVS-PL-V002 was opened. The pre-operational test conditions were re-verified and CVS-PL-V003 was closed and verified to be closed locally.

The completed test results (Reference 1) demonstrated that each motor-operated valve for Unit 4 changes position as indicated in Table 2.3.2-1 under pre-operational test conditions.

Testing was performed in accordance with work orders listed in Reference 1 to confirm that each check valve with an active safety function changes position as indicated in COL Table 2.3.2-1 (Attachment F) under pre-operational test pressure, temperature, and fluid flow conditions.

Testing established the pre-operational test conditions of gas flowing to CVS-PL-V217 with a pressure between 58.1 and 59 psig. CVS-PL-V217 was verified to open by test connections on CVS-PL-V218 and CVS-PL-V216. Once required pressure was reached, CVS-PL-V217 was

U.S. Nuclear Regulatory Commission ND-23-0417 Enclosure Page 7 of 16 verified to close by measuring its leakage rate, which is within the containment leak rate test program limits (i.e., approximately 0.6% of the administrative limit).

Testing established the pre-operational test conditions of RCS at atmospheric pressure and ambient temperature and makeup in service. CVS-PL-V081 was closed and CVS-PL-V067 was verified to be open by ultrasonic flow indication. CVS-PL-V081 was reopened, and ultrasonic flow indication (no flow) and non-intrusive monitoring were used to demonstrate that CVS-PL-V067 was closed.

Testing established the pre-operational test conditions of RCS at atmospheric pressure and ambient temperature and makeup and purification in service. CVS-PL-V091 was closed and CVS-PL-V100 was verified to open by ultrasonic flow instrument indication. CVS-PL-V091 was opened and CVS-PL-V100 was verified to close by flow indication (no flow).

Pre-operational test conditions were established with the RCS at 555°F - 559°F degrees and 2220 psig - 2250 psig for the performance of the check valve testing that follows.

With pre-operational test conditions established and purification flow established, CVS-PL-V001 was closed and check valves CVS-PL-V080, CVS-PL-V081, and CVS-PL-V082 were verified to close using non-intrusive valve disc position verification.
