During 40EP-9EO09 Functional Recovery, what is the Success path prioritization?
- Jeopardized
- Challenged
- Not impaired
During 40EP-9EO09 Functional Recovery, which success paths require no further action once met (shaded)
- RC-1 - CEA insertion
- MVAC-1 - Off-site power
- MVAC-2 - DG power
- CI - CNTMT isolation
During 40EP-9EO09 Functional Recovery, who directs the performance of each success path?
- CRS
During 40EP-9EO09 Functional Recovery, Who can the CRS delegate non-jeopardized success paths to?
- Other available licensed operators
- BOP/OATC/STA address jeopardized funcitons
During 40EP-9EO09 Functional Recovery, what action is required if Rx Power criteria in NOT met for Reactivity Control?
- Stabilize Tc
- Borate
During 40EP-9EO09 Functional Recovery, What is the minimum RWT level to use CH pumps as a boration path?
What is the minimum SFP level?
- RWT > 44%
- SFP > 133’ 6”
During 40EP-9EO09 Functional Recovery if using the HPSI pump for boration, what is the minimum flow?
- ≥ 75 gpm
- Sq root extractor minimum
- Ensures > 40 gpm
During 40EP-9EO09 Functional Recovery, which DG’s from another unit can be cross connected?
True of False during 40EP-9EO09 Functional Recovery, MVAC and MCDC must be satisfied from the same train?
- True
During 40EP-9EO09 Functional Recovery, if Vital Battery Chargers cannot be restored in 2 hours, what actions must be performed and why?
- Vent SIT’s
- Prevents N2 injection to RCS
During 40EP-9EO09 Functional Recovery, what is the minimum HPSI Flow if SBOG’s are providing power to the HPSI pump?
- > 165 gpm
- Use RCGVS to lower pressure if needed
During 40EP-9EO09 Functional Recovery, what are the required conditions to use CSP for RCS injection?
- Ppzr < 220 psia
- LPSI not available
- CSP not needed
- CSP needed for IC
- RAS not actuated
- CS flow < 5000 gpm (pump damage)
During 40EP-9EO09 Functional Recovery, What condition must be met for RCGVS to be EFFECTIVE?
- RCS subcooled
- Bubble will form and hold pressure if not
Where can each train of RCGVS be vented to?
A - CNTMT
B - RDT
When operating AFA locally, what is the concern when lowering SG flow?
- Overspeed trip
- Less work, same steam flow => speeds up
During 40EP-9EO09 Functional Recovery, HR-1 addresses which casualties in which order?
- SGTR
- ESD
- LOAF
During 40EP-9EO09 Functional Recovery, with a ruptured/ faulted SG, what is the required feed rate, level and why?
45 - 60% NR
1360 - 1600 gpm
- 1360 - reduce offsite dose
- 1600 - stress on SG (water hammer/ thermal)
During 40EP-9EO09 Functional Recovery, what is the MINIMUM level to minimize offsite dose with a Ruptured/ Faulted SG?
- Above SG tubes
- ≈ 22% NR
During 40EP-9EO09 Functional Recovery, how long do you have to start feeding a Ruptured/ Faulted SG?
- 16.67 minutes TCA
During 40EP-9EO09 Functional Recovery, how many AF pumps do you feed with? why?
- 2
- AFA will not provide enough feed alone
- 3 pumps could exceed max flow for feedring (2000 gpm)
During 40EP-9EO09 Functional Recovery, what are the requirements to use LPSI for CS flow
- CSAS actuated
- Unable to maintain 4350 gpm
- LPSI pump not needed
- LPSI < 60 amps
- THERE WILL BE NO FLOW INDICATION
What are the guidlines for stopping CS pumps?
Both on miniflow and not expected > 8.5 psig in 1 hour
< 5 psig, not needed for iodine removal/ H2 mixing and one of:
- CNTMT cooling restored
- SDC in svc
Stop 1 CSP:
- < 50 psig, SI flow adequate
During 40EP-9EO09 Functional Recovery, when are Long Term Actions implemented?
- All success paths perfomed
- SFSC for paths satisfied
During 40EP-9EO09 Functional Recovery, what is the NORMAL SDC entry criteria?
- Lpzr > 30% [38]
- ≥ 24°F [44] subcooled
- Ppzr < 385 psia
- Th < 335°F
- RCS activity wont make AB unacceptable
During 40EP-9EO09 Functional Recovery, what is the LOSS OF SUMP RECIRC SDC Entry Criteria?
- Ppzr < 385 psia
- Th < 335°F or REP CET < 350°F
- RVUH ≥ 16%
- RCS activity ok for AB
