Section XL
,1.2 To perform a quarterly full stroke of 2CC-724A&B,2P-11 A&B discharge check valves
. as required by ASME Section XI.
1.3 To perform a quarterly full stroke of 2CC-738A&B, CC to HX-11 A&B RHR heat exchangers as required by ASME Section XI, and annual stroke to satisfy environmental qualification requirements.
1.4 To perform a quarterly non-quantified backleakage evaluation of 2CC-724A&B, 2P-11 A&B discharge check valves as required by ASME Section XI.
2.0 PRECAUTIONS AND LIMITATIONS-2.1 IF TIIERE IS ANY PROBLEM IN PERFORMING THIS TEST, IMMEDIATELY
- NOTIFY THE DUTY SHIFT SUPERINTENDENT. ' OPERATION OF THIS EQUIPMENT IS A TECHNICAL SPECIFICATION REQUIREMENT (15.3.3.C).
2.2 Mir.imum flow required for a component cooling water pump during continuous operation is 100 gpm.
2.3 Flow combinations in the component cooling system' are shown on Figure 1 of OP 6A.
Maximum CC flow rate through a single CC heat exchanger is 7862 gpm.-
I.4 L Care must be exercised when handling the treated component cooling. water because it is 2
- mildly toxic. _ Refer to AOP 12A, " Oil and Hazardous Material Spill," and the WE CHES LManual for the Health llazards of Potassium Chromate.
.' 2.5 The dedicated' operator that is required for 2CC-824A/B is a level 3 dedicated operator.
Upon receipt of a U2 SI signal, the dedicated operator will need to reposition the valve per the local plaque prior to initiating sump recirculation.
