I will explain the initial conditions and state the task to be performed. You will be allowed to use any reference normally available in the Control Room to complete the task. Ensure you indicate to me when you finish your assigned task by returning the material needed for the task that I provided to you.
Initial Conditions Unit 2 is at 100% power. The 2B CCW pump has developed a shaft seal leak. The pump seal requires replacement. No other equipment is out of service. The 2C CCW pump has been mechanically and electrically aligned and is running on the B header.
Initiating Cue On the attached matrix, develop a Tag out boundary for the 2B CCW Pump that would facilitate replacing the pump shaft seal.

Prior to opening drain, contact Chemistry (see note bottom of page)
NOTE: Pull to Lock position is critical step in that if pump were left in spring loaded stop position the 2C CCW pump would not start on LOOP.

- As per Ops Policy 406, Vents and Drains do not require a danger tag. It is preferred, but not required.
- V14536 Drain Open #Danger
- V14145 Drain Open #Danger
- V14149 V14549 Vent Open #Danger NOTE: Only one of the two drains are required. If both drains are opened that is acceptable also.
- Critical Step NOTE From ADM-09.08, Operations In-Plant Equipment Clearance Orders, step 3.3.12:
Prior to draining, obtains verification from chemistry that NO biocide hazard exists before issuing a clearance on the TCW system, CCW system or EDG Cooling Water Systems that may require the draining of liquid from the system.
From 0-NOP-24.01, Draining Potentially Hazardous Or Toxic Systems to The Environment. Chemistry should also be questioned if the CCW system has any activity. If Chemistry questioned, state there is no activity in the CCW system. (Normally the SRO would coordinate with Chemistry to determine the drain path for CCW. i.e. activity and nitrate concentration).
