TREQ 1648565-55 During shift in early September 2015 a leak was identified on the FC pool gate that separates the cask wash down pit from its adjacent pool. During initial investigation it was apparent that several operators were unaware of the capabilities or limitations of these pools and pits that are WEST of the 755' FB IFTS Fuel Transfer Pool. One knowledge deficiency in particular was that the fuel cask wash down area (pit) was not immediately recognized as NOT being a pool that would be capable of retaining fuel pool water if a seal failure were to occur. This information was either not covered or not retained by operators when the FC system review was performed. I do recall that there was some brief discussion about how the upcoming handling of casks may occur.

OPEX Beaver Valley Unit 1 2015-11-10 1 :57 PM

1. 320530 Failure of DG CO2 System to Actuate During Surveillance Testing Abstract:

On 11/10/15 during the 18 month surveillance test of the Unit 1 number 1 Diesel Generator CO2 system, the valves for the CO2 system did not actuate when tested from a Manual discharge pushbutton. In the event of a fire CO2 fire suppression would reduce the potential for damage to safety-related equipment important to safe shutdown. The cause was a pilot valve mechanical plunger became stuck.

Since a compensatory firewatch was established this event had minimal impact on station operations.

BC081r4_Controllers 4. State the purpose of a controller.

A controller is device that compares input signal with setpoint and generates output based on difference ( error signal)

Five types of controllers:

1. Two position controller

2. Proportional controller

3. Proportional plus derivative

4. Proportional-plus-reset controller

5. Proportional-plus-reset-plus-rate controller 96

BC081r4_Controllers 5. Describe the theory of operation of the following types of controllers:

Two position Two-Position Controllers The device has two positions: on or off The opening and closing of final control element results in cycling characteristic of measured variable ON WATER FLOW OFF -

BC081r4_Controllers 5. Describe the theory of operation of the following types of controllers:

Proportional plus derivative The proportional plus derivative (PD) controller or rate controller results in a more rapid response and less offset than the pure proportional controller.

99

BC081r4_Controllers 5. Describe the theory of operation of the following types of controllers:

Proportional-plus-reset controller Offset Error:

The difference between setpoint and measured variable is called "error" This error signal maintains control valve at specific position in response to change in demand of system Proportional-plus-reset controllers automatically reset measured variable to setpoint, thus, offset error is eliminated 100

BC081r4_Controllers 5. Describe the theory of operation of the following types of controllers:

Proportional-plus-reset-plus-rate controller To overcome disadvantages of Pl controller, "rate section" may be added 101

Valve Characteristics The flow characteristic of control valve is relationship between flow rate through valve and percentage of valve travel

a.

To compare and discuss flow characteristics of valve, it is helpful to plot curve as percentage of travel versus percentage of flow

% SPAN OF POSITIONER OUTPUT PRESSURE 102

Valve Positioner The primary function of valve positioner is to maintain control valve disk at position that is directly proportional to its controller output pressure A valve positioner can be used to reverse signal to valve and to overcome frictional forces within valve on high-pressure drop applications.

Valve positioners are usually mounted on side of diaphragm actuators and on top of piston and rotary actuators Because of large volume of pneumatics required to operate valve, valve positioner has independent, regulated, pneumatic supply.

Use of valve positioner should be considered for systems where it is necessary to provide control of process with minimum overshoot and fastest possible recovery following disturbance HIGH PRESSURE PNEUMATIC SUPPLY FAIL CLOSED (normal seated valve) 103

Valve Positioner cont.

In many cases, valve positioner improves performance of process control loop Studies have shown that use of valve positioners is clearly beneficial in slow processes and clearly detrimental in fast processes use of valve positioner should be considered for systems where it is necessary to provide control of process with minimum overshoot and fastest possible recovery following disturbance HIGH PRESSURE PNEUMATIC SUPPLY FAIL CLOSED (normal seated valve) 104

1 PA05J controller operations (02422997-82)

Request: Training be performed for E0-1 and EO-C populations on 1 PA05J controller operations.

Newer equipment operators do not have full understanding of how to operate Bailey/NUS controllers at the 1 PA05J panel in a transient condition.

Feedwater Heater Abnormal Level 8.3.1 Feedwater Heater Abnormal Level CAUTION

<<CM-7>>

A Low level in the heater may cause level to be too near the bottom of the "snorkel" which will introduce a possible steam path into the drain cooler which would cause increased vibration and would lead to tube damage. See Appendix F: Feedwater Heater Distance To Snorkel.

Time spent with a low heater level must be minimized to reduce the potential for heater tube damage.

Highfeedwater heater levels cause extraction steam valves to the respective heater to close. If this occurs, refer to CPS 4005. 01, Loss of Feedwater Heating while continuing in this procedure.

NOTE See Appendix B, HEATER VALVE LIST for valve numbers associated with each heater vessel.

Emergency drain valve controller output is" 100%for valve fully closed.

Normal drain valve controller output [s 0%for valve fully closed.

1.

IF Feedwater Heater Abnormal Level is result of a system malfunction or FW heaters are not operating properly, THEN

1)

Refer to CPS 4005.01, Loss Of Feedwater Heating for possible entry*conditions.

2)

As necessary to help determine heater level high or low, use Appendix G, Feedwater Heater Level Diagnostics.

3)

Determine which drain control is malfunctioning, and if necessary, take manual control of the valve.

4)

If normal drain valve control is malfunctioning, it will be necessary to reduce the emergency drain setpoint in order to maintain relatively normal heater level.

In this case, normal drains should be positioned in manual to maintain as little flow as practical through the emergency drains.

5)

If any heater controls are left in manual, the controls should be checked frequently due to the possibilities of controllers drifting in manual and due to changing demands that occur with123 small load changes.

310201.16 Respond to Feedwater Heater Abnormal Level cont.

8.3.1 Feedwater Heater Abnormal Level (cont'd)

2.

IF Feedwater Heater Abnormal Level is result of a plant manipulation 9r transient (i.e., bypass valve operation, removal/

restoration of FW Htrs, etc.),

<<CM-6>>

THEN After stabilization of the feedwater heaters, verify proper operation of the feedwater heaters:

1)

Normal level being maintained. (P680/1PA05J).

2)

Normal and Emergency Drain Controllers operating properly.

3)

ES isolation valves positioned correctly.

4)

FW heater bypass valves positioned correctly.

5)

BOP-5 video services parameters indicate normal values.

6)

Feedwater temperatures are normal.

NOTE JCB003A(B) and JCB005A(B) isolate (close) on Flashtank high level.

If condensate flow is attempted to be restored with Flash tank high level sensed, the heater isolation valves (JCB003A(B) & 5A(B)) will stroke open then immediately closed.

124

310201.19 Preparing Feedwater Heater Level Control For Maintenance Or Trouble-Shooting Of A Normal Drain Valve Malfunction CAUTION Section 8.2.3.1 shall be reviewed prior to proceeding due to changes infeedwater heating.

8. 3. 4 Preparing Feedwater Heater Level Control For Maintenance Or Trouble-Shooting Of A Normal Drain Valve Malfunction

1.

At panel 1PA05J, verify level indicating cont.roller for the emergency level control valve is in AUTO, and controlling at a reduced setpoint as described in 8.3.1.1.3.*

2.

Verify/place the normal drain*controller in MANUAL.

3.

Slowly close the normal drain valve using the closed push button on the level indicating controller while observing that the emergency level controller responds to maintain heater level.

4.

IF Necessary due to the malfunction, THEN

1)

Isolate the malfunctioning drain valve.

(refer to Appendix B Table 1 for list of normal drain isolation valves)

2)

Ensure the emergency level controller is maintaining heater level as desired on emergency level indicating controller.

5.*

WHEN Trouble-shooting/maintenance is complete, THEN Ret1.hn normal drain regulator to service by performing the following as appropriate:

1)

Appropriate portion of CPS 3102.01V002, Heater Drains Valve Lineup completed (if needed).

2)

Appropriate portion of CPS 3102.01V004, Heater Drain Instrument Valve Lineup completed (if needed).

3)

Open the heater normal drain valve until the emergency drain automatically closes, and place the normal drain valve in automatic.

4)

Restore the heater emergency drain controller setpoint to its nominal value.

Phase Separators - 3909.02 D

1iscussion The Phase S~parators collect waste sludge from the Reactor

. ~'Jater Clean Up Fi 1 ter Demineralizer Backwash Receiving Tank..

After a sufficient volume of slu,dge has-been accumulated, tank contents are decanted, recirculated and transferred to a Vendor for processing.

Once tank contents have b*een transferred, the tank an*d associated components are flushed to remove sludge residue.

Tank recirculation is normally performed manually.

Flushing 0£ the tank ~nd associated components is also performed manually..

Operation of the Phase Separator Sludge System to transfer sludge for processing will be a coordinated evolution bet,ueen Operations and Vendor.
