Exam 11 prep Flashcards
(111 cards)
1
Q
What is the purpose of PPS?
A
- Assure SAFDL AND pressurizer safety limits are not exceeded during an Anticipated Operational Occurrence
- Redundant and independent to ensure
- No single fault will cause an actuation
- No single fault will cause a loss of safety function
- 4 separate (train) sensing channels
- 6 logic matrices that contain relays to trip RTSGs
2
Q
How does a loss of one PN bus affect PPS?
A
- Loss of a single PN power supply: 2 RTSGs open (A & C OR B & D)
3
Q
How does a loss of 2 or more PN buses affect PPS?
A
-
Loss of any 2 or more PN power supplies: Rx Trip
- Also due to instruments losing power you will get a FULL ESFAS actuation. (Every signal except LOP)
4
Q
What happens in PPS if a single parameter exceeds its trip setpoint?
What actions are required and how long do you have?
A
-
Single parameter exceeding trip setpoint: No trip only alarms
- If the instrument is determined to be bad causing this trip then we will bypass it. (New logic is now 2 out of 3 instead of 2 out of 4)
- 1 hour time limit to get this channel bypassed
5
Q
What will happen in PPS if one parameter is bypassed in A train and its trip setpoint is exceeded in B train?
What actions are required and how long do you have to do it?
A
- One parameter in bypass the same parameter has a trip on another channel: NO TRIP (Only 1 out of 3, needed 2 out of 3)
- If this is also due to a failed instrument then within 1 hour 1 channel is placed in bypass and the other is tripped (this is done by I & C)
6
Q
What should be done to the signals associated with PPS A if PNA is lost?
A
-
ALL signals on that associated cabinet should be bypassed.
- Since these are pushbuttons that stay depressed even though power is gone the bypasses will still work
7
Q
Which leg of ESFAS logic is responsible for valve group actuations? Pump group actuactions?
A
- 1-3 leg (Valve group relays)
- 2-4 leg (Pump group relays)
8
Q
How does loss of a single PN bus affect the ESFAS portion of PPS?
A
- Half leg trip on both A and B trains (same leg)
- The bottom of the electrical circuit for initiation relays is basically “cross-connected” so you need contacts to open on both legs to cause a full actuation. (A SINGLE CONTACT GOING OPEN WILL NOT MOVE ANYTHING)
- There is a fuse in the current return for each leg
- IF this fuse were to blow then the associated relays of that leg will also de-energize causing an actuation of its associated components (half leg trips)
9
Q
What type of manual initiation is available from B05?
What configuration will ensure complete esfas actuation?
A
-
Manual initiation of each channel is available for each train from B05
- However there is a catch: FOR A FULL ACTUATION YOU MUST TAKE MORE THAN ONE CHANNEL TO INITIATE TO HAVE AN ACTUATION. (Also the 2 MUST NOT be same train A&C/B&D)
10
Q
At the Aux relay cabinet, how are initiation signals manually initiated?
How are channels reset at the Aux relay cabinet?
A
-
Trip/Resetting @ Aux Relay Cabinet
- To Reset ONLY 1 BUTTON PRESS IS NEEDED (for 1 Train)
- To Initiate 2 BUTTONS ARE REQUIRED (for 1 train)

38
What would happen if an attempt to bypass the same parameter across multiple PPS channels was performed?
* **Bypassing Parameters on PPS Cabinets**
* There is a priority. YOU ARE NOT ABLE TO PLACE THE SAME PARAMETER IN BYPASS ON MULTIPLE CHANNELS
* **It will automatically ensure 2 channels aren’t bypassed on the same parameter by removing one of the parameters from bypass**
* Priority: A→B→C→D. So if “B” is already in bypass for a parameter and “A” bypass button is pushed “B” will come out of bypassed. The same relationship exists for “B” to “C” (“C” would “lose”)
* The same priority is available for being able to place a channel in test
39

* **YOU ONLY GET ONE FILL TO 40.8% WR and the DAFAS WILL NOT FEED ANYMORE**
* If you get a MSIS in the middle of a DAFAS actuation it will stop feeding. Pumps will remain running.
* **8 keys to bypass DAFAS in the Aux Relay Cabinets - fun fact.**
42
With regard to RAS, should it be manually initiated based on RWT level trending towards its setpoint?
Why or why not?
* **RAS should NEVER be manually initiated on trend this allows enough water inventory into containment**
43
What happens to the LPSI pumps and miniflows on a a RAS initiation?

47
What will occur if the Linear Calibration switch on the Safety ex core drawer is placed in a position other than OPERATE?
* Placing the **Linear Calibration** switch on the ex-core safety channel NI drawer to **other than the OPERATE** position will cause a channel **Variable Overpower trip**.
48

* Placing the **Logarithmic Calibrate** switch on the NI drawer to **other than the OPERATE** position will cause a channel **High log power trip**.
49
What will occur when depressing the TEST pushbutton on B05?
How do you reset this?
* **Depressing the TEST Push Button**
* Lights **all three sections of the bistable status indicators on the ROM** and **similar indicators** on the corresponding PPS cabinet **BCP**.
* **Releasing the TEST PB will extinguish only the BYPASS** portion of the bistable status indicators.
* Returns the white P (pretrip) and red T (trip) sections of the bistable indicators to their original state if the alarm or test condition has cleared.
* Pre-trip and Trip lights will stay lit until this happens.
50

* **4 total 2 “A” train and 2 “B” train**
* **These are powered by their respective PK busses**
53
What ensures there is negative pressure in the Aux bldg?
* A SUPPLY AHU CANNOT BE STARTED unless an EXHAUST FAN IS ALREADY RUNNING
* **This is sensed by D/P across AFU fans**
* 2 SUPPLY AHU’s CANNOT BE RUNNING WITH JUST 1 AFU RUNNING
* **IF “A” AHU and “A” AFU are running and the “B” AHU is taking to start then the “A” AHU trips off to ensure just a 1 for 1 combo**
* This same pattern holds true if 2 “B” train units were running.
* **Here’s where it gets really silly**
* IF “A” AHU and “B” AFU are running and the “B” AHU is taken to start……**it will not start**
* **IF all 4 are running and a LOW D/P condition is sensed on the “B” AFU then the “A” AHU WILL TRIP**
* Same holds true for “A” AFU and “B” AHU

* **1 fan can handle the total heat load though 2 are usually running**
* Both ACU’s are supplied from a **common suction.**
* Powered from Class Load Centers **PG**
63
What is the auto start of the CEDM ACUs?
* Standby Units will auto start on a **low D/P** @ **120 secs after low D/P**

64
When should the CEDM ACUs be placed in operation?
What action is required if CEDM cooling is lost when RCS is \> 300F?
* ACUs must be in operation prior to \>225F RCS temp
* **If CEDM cooling is lost and RCS Temp \>300F then CEDM cooling must be restored or the CEDM must be de-energized w/in 40 minutes**
65
How do the CEDM and Cont normal ACUs operate during a SIAS?
During a LOP?
* **SIAS**
* **Containment Normal & CEDM ACUs stop on a SIAS**
* May be overridden

* **LOP**
* **Running Containment Normal and CEDM ACUs will load shed and then be restarted by the sequencer ~ 55 secs into the sequence**
66
How do the Rx cavity fans and Pzr normal fans operate?
* **Reactor Cavity Fans & Pressurizer Normal Cooling Fans**
* **Powered by SIAS LOAD SHED PANELS**
* Both will auto start the opposite fan on a sensed low D/P
67
How do the MSSS supply fans operate?
* Normally 1 AHU and 1 Filter is running while the other is standby
* Standby fan will auto start on low D/P
* **2 exhaust fans are installed to remove heat from the MSSS 100’ and above.**
* Each fan takes suction on one side of the MSSS and therefore both are normally running.
