* 0POP04-DJ-0001 Loss of Class 1E 125 VDC*
* * *
What is RCDT discharge flow limited to?
**10 gpm**
## Footnote
* * *
If excess letdown directed to RCDT, must realize you are sending ≈ 20 gpm in and only 10 gpm out of RCDT.
* * *
*Note:
States many times in procedure that if you lose Class 1E 125 VDC Train B then excess letdown will realign to VCT.*

* * *
What must be done if **_LOCAL_** CCW HX temperature is \> 105 ˚F?
**Ensure HCV-0285 100% Open**
**Start PDP**
**Throttle HCV-0285**
**Place CCPs in PTL**
**Shut FV-0011**

* * *
What plant personnel must be informed of an unauthorized discharge?
**Unit Operations Manager**

**Duty Plant Manager**
**Resident NRC Inspector**
83
* 0POP04-RS-0001 Control Rod Malfunction*
* * *
If there is a dropped or misaligned rod, how far must the operators lower power to recover it?
* _No Power Reduction:_*
* *Fixed within 1 hr**
* _Lower to 75%:_*
* *Must Lower to 75% within 2 hrs**
**Lowering power to 75% within 1 hr allows you 4 hrs to fix problem prior to reducing power further**
* _Lower to 40%:_*
* *If power was not reduced to \< 75% within 1 hr**
84
* 0POP04-RC-0002 RCP Off Normal*
* * *
What must the operator do if all seal cooling is lost to the #1 RCP seal?
**Trip Rx**
**Ensure Main Turbine Tripped**
**Trip affected RCP within 1 minute**
**Perform 0POP05-EO-EO00**
* * *
**If RCP Seal temp \< 230 ˚F:**
* **Ensure PDP Recirc Valve 100% open**
* **Start PDP**
* **Slowly close PDP Recirc Valve to lower seal water bearing temp \< 1˚F/min**
85
* 0POP04-CC-0001 CCW System Leak*
* * *
If CCW is lost to the CCP Supplemental Cooler or to the CCP lube oil cooler, how long until CCP failure?
* _Supplemental Cooler:_*
* *4 minutes**
* _Lube Oil Cooler:_*
* *8 minutes**
86
* 0POP04-IA-0001 Loss of Instrument Air*
* * *
What IA pressure is a manual Rx Trip required?
**60 psig**
87
* 0POP04-AE-0007 Loss of all AC while on S/D Cooling*
* * *
What are the time sensitive actions to ensure the Class 1E batteries last 8 hrs?
* _Batteries will last 4 hours:_*
* *De-energize ESF Sequencers (30 mins)**
* _Batteries will last 8 hours:_*
* *Initiate FSG04 (Deep Load Shed) (30 mins)**
**Complete FSG04 (2 hrs)**
* * *
Initially Class 1E Batteries will only last 2 hrs.
88
* 0POP04-RS-0001 Control Rod Malfunction*
* * *
What actions must be taken if a control rod is deemed untrippable?
* _1 Rod:_*
* *Be in MODE 3 in 6 hrs**
* _≥ 2 Rods:_*
* *Trip the Rx, Go to EO**
* * *
*Note:
I&C must verify current on grippers before a stuck rod is considered untrippable.*
89
* 0POP04-RP-0002 Loss of Automatic PZR Level Control*
* * *
What are the immediate actions of 0POP04-RP-0002 Loss of Automatic PZR Level Control?
**Place FK-0205 in Manual**
**Adjust FK-0205 to maintain PZR level**
90
* 0POP04-FW-0001 Loss of SG Level Control*
* * *
What must be done if you are on the LPFRVs, they fail to respond in auto or manual, and the MFRVs are not responding?
* _≥ 5% Rx Power:_*
* *Trip the Rx**
**Perform 0POP05-EO-EO00**
* _\< 5% Rx Power:_*
* *Reduce power to 3% Rx Power**
**Transition to AFW**
91
* 0POP04-RP-0002 Loss of Automatic PZR Level Control*
* * *
What must the operator do if PZR level reaches 17%?
**Secure Letdown**
**Secure Charging**
**Secure PZR Heaters**
* * *
Must secure charging because letdown is secured and, in AOP Land, you do not want to stress the PZR spray nozzle.
92
* 0POP04-RC-0002 RCP Off-Normal*
* * *
What is the basis for closing the #1 Seal leakoff valve 3 mins to 5 mins after securing the RCP during a high #1 Seal Leakoff flow alarm?
* _3 Mins:_*
* *Allows RCP to stop so you do not damage the #2 Seal**
* _5 Mins:_*
* *Reduces damage to Bearings, Seals, and Shaft**
