Compiled systems notes (CE,CEDMCS,COLSS,COND OPS, CONTROL OIL)

what cools CE isophase?

Turbine cooling water

what happens to stator cooling on a loss of NKN-D41?

no stator cooling trips

how do we do the auto start test?

press a button that simulates a low flow condition, pump must be manually secured

what three signals from the main turbine will not start the standby pump?

generator differential, stator ground, and unit differential

what will happen when you get the stator cooling green trouble alarm?

you have 70 seconds to resolve the issue or the unit will trip

what is the purpose of SLMS

monitors H2 being vented to the roof

how many quadrants are lost for CEDMCS on a loss of PND

¼ anti pac man

what does a CWP prevent?

CWP prevents all outward CEA motion in any mode

where can the RTSG breakers be operated from?

locally at the breaker, the SPLA, and PPS

what is the maximum limit we can withdraw a CEA

maximum withdrawal is the upper electrical limit (UEL)

what do the RSPT input to the PC when a rod drops?

inputs a 0

if the CWP is placed in bypass what is the one mode of operation the CEA CAN NOT be moved in?

they can not be moved in stby with CWP bypassed

what signals will bring in a CWP?

2/4 HI PZR pre trip

2/4 LO DNBR pre trip

2/4 HI LPD pre trip

RPCB (clears after 10 seconds)

CEA misalignment from CPC/CEACS

what rates can we insert CEAS?

CEAS move in at 30 inches per minute or 3 inches per minute

how many inches is reg group overlap?

90 inches

where do we get the UGS (upper group stop) and LGS (lower group stop)?

they are generated from up and down pulse counts from internal logic from ovation

what happens to pulse counters on a CEA slip (not drop)

counters will not see a Slip and will not reset at all

what does CEACs provide on a CEA deviation

provides a penalty based on direction of deviation

what are the safety channels calibrated to?

safety channels are calibrated with JSCALOR

what happens if FW flow is less than actual?

the VOPT will be less conservative

what happens to COLSS if in core instrumentation fails?

COLSS will be out of service

what does the power limit margin compare?

compares licensed power to selected power (smooth)

If COLSS Tcold lowers by 5f what happens to power as read by JCPCAL immediately, and over an hour

If Tcold goes down power will initially go up but over time will be corrected by JSCALOR and brought back down

what happens to tilt on a slipped CEA?

tilt will go up due to ICI seeing flux shifting

how does COLSS see view a dropped CEA

COLSS will view a dropped CEA as if the whole group has dropped

what happens to LPD POL if CEAs lower in the core

LPD POL will lower

what happens of LPD and DNBR POL if PZR pressure lowers

DNBR pol lowers, but LPD pol is unaffected

what happens to JSCALOR if FW temp fails low

JSCALOR will go up and overtime affect the other powers

what happens to DNBR POL if ASI becomes more negative

DNBR POL goes down

what is the purpose of COLSS vs CPC

COLSS is for indications and alarms

CPC is for protection and trips

if BD is secured with constants still in what will happen to JCPCAL?

initially lower and lower an hour later due to a lowering JSCALOR

If RCP DP lowers what is the affect on NKBDELT

RCP DP lowering will cause NKBDELT to go up

if BD is secured but constants are still in, what affect does this have on the JSCALOR VOPT

JSCALOR VOPT is less conservative

how are input failures sensed by PC and CMC

Input failures are sensed by both the PC and CMC

How are alarms reported in the control room?

reported to the CRS without delay using 3 way communication

what is unique about the BDAS and PDIL alarms

these alarms can not be left in fast flash

who is allowed to take command function in mode 5 and 6

an RO is now able to take command of the control room

what are the two handed operations in the control room

ADV, Aux feed, HPSI, SIAS/CIAS

how often does an RO perform board walkdowns

walkdowns performed every two hours

who is responsible for overall appearance of the CR? who is responsible for scheduling painting and MODs

SM is responsible for the overall appearance of the control room

UOM is responsible for scheduling painting and mods

what is required in order for the peer checker and the IV to be the same person

SM approval and a CR must be generated

what defines an “expected alarm”

the alarm must be briefed

who monitors the plant during shift turnover?

OATC

describe the alignment for control oil cleaning

control oil flow control valve diverts flow through filters for clean up

what is the logic and setpoint for EHC turbine trip?

setpoint at 1100 psig

2/3 logic

when does the standby control oil pump auto start?

auto starts at 1300 PSIG
