Functional recovery procedure

what are the entry criteria for the functional recovery procedure?

ELAP is not in progress

SPTAs complete

• Any condition, or pattern of symptoms, for which abnormal or emergency guidance can NOT be identified 

• Actions taken in an ORP are NOT satisfying the SFSCs 

• Multiple event conditions exist 

what are the Exit criteria for the functional recovery procedure?

ELAP is in progress

OR

you can enter the ORP

OR

SAMG entry is required (CETs greater than 1200F)

when is SAMG entry required?

when CETs are greater than 1200F

how do we implement success path prioritization?

1) Jeopardized safety functions success path not met

2) Challenged safety functions, conditions are met but need support to continue to be met

3) success paths that are not impaired,

what is required when a shaded safety function is met?

Shaded success paths require no further action once met

RC-1, MVAC-1, MVAC-2, CI 

who delegates the performance of each success path?

CRS

what may the CRS delegate to other available licensed operators?

CRS may delegate non-jeopardized success paths to available Licensed operators (cant be BOP, OATC, or STA)

RC actions, what is required if reactor power criteria is not met?

stabilize Tcold (a DROP in RCS temp may result in a core restart)

what is the consequence of aligning Charging pump discharge to the HPSI path?

Seal injection and Aux spray will not be available

what is the minimum RWT and SFP level for boration?

RWT is 44%

SFP is 133’6 (bamp suction line)

what is required to inject with a HPSI pump and how is it achieved?

RCS depressurization is needed

depressurize with

RCS heat removal

HTRS and spray

what is the goal flow rate for injecting with the HPSI pump? why?

greater than or equal to 75 gpm indicated HPSI flow (square root extractor) ensures 40 GPM boration flow

what is required to satisfy MVA?

MVDC-1 and MVAC must be satisfied and supplied from the same train in order to satisfy MVA

all the vital busses have only one other units DG available, what unit is the unit 3B DG available to?

3B DG to U1 PBA-S03

if PK is energized from the battery only, what is the status of the MVDC-1 success path?

the MVDC-1 is challenged

if vital battery power cant be restored within 2 hours, what guidance is available to address the SITs and why?

Guidance to vent the SITs to prevent N2 injection

what is required if an ELAP is in progress?

go to the Blackout procedure

what would have us align a CS pump for RCS injection (app. 107)

PZR pressure less than 220 PSIA (LBLOCA)

LPSI not available

CS pumps not needed to meet CTPC

CS pumps not required for inventory control

RAS has not acutated

CSP pump flow greater than 5000 GPM may cause runout

if IC-1/2 are not met, what actions are taken? what affect can this have?

rapid RCS cooldown and depressurization will break flow and allow for SIT/LPSI injection if needed

what actions are taken in PC-1?

maintains pressure within P/T limits?

during PC-2, if both trains of PZR vents are available, where would we vent to? what if only A is available? what if only B is available?

both trains available, vent PZR to CTMT

if only A train, vent to CTMT

if only B train, vent to RDT

RCS must be subcooled for PZR vents to be effective

what can occur when operating AFA and you start reducing its flow?

overspeed trip (less work same steam will cause RPMs to go up)

what does HR-1 address?

HR-1 addresses SGTR, then ESD, then LOAF

what actions are taken on a ruptured /faulted SG that is steaming to atmosphere?

feed at 1360-1600 GPM until SG level has restored to 45-60% NR

get level above the TUBES (22% NR) to scrub volatiles

16.67 minute time critical action to commence feeding

what should be done when entering the FRP with a faulted SG or stopping RCPs for a LOAF

pull forward the steps as soon as the FRP is entered

what will cause CI-1 to be jeopardized?

will be jeopardized if SGTR or RCS to NC leak exists and they have not been isolated

what actions will CI-1 take to address SGTR, and IC for RCS to NC leak?

will send you to HR to address the faults

what actions are taken if both CS pumps are running on miniflow and you're not expected to exceed 8.5 PSIG within 1 hour?

stop both CS pumps

what conditions must be met to align LPSI to supply spray flow?

CSAS has actuated

unable to maintain 4350 gpm CS flow

LPSI pump is not needed

check LPSI amps greater than 60

if flow is not detected evaluate the system to verify proper operation

what is the guidance for stopping spray flow?

stop 1st CS pump if CTMT is less than 50 PSIG and not rising, and SI flow is adequate

stop CS if CTMT pressure is less than 5 PSIG and not needed for IODINE removal, long term cooling ECT

when are long term actions (LTA) taken?

implemented after all selected success paths in use have been performed and SFSC acceptance criteria for selected success paths are being satisfied

what are the SDC entry criteria? (normal conditions)

Lpzr greater than 30% and controlled

greater than 24F and subcooled

PZR less than 385 PSIA

Thot less than 335

RCS activity will not result in radiological consequences outside of CTMT

what are the SDC entry conditions with a loss of sump recirc?

PPZR < 385 psia 

Thot < 335°F OR REP CET < 350°F 

RVUH ≥ 16% (minimum inventory/NPSH for SDC operations, middle of the hot leg)  

RCS activity will NOT result in unacceptable radiological consequences outside containment
