diate action should be taken to reduce core temperature by
using Emergency SCRAM 'ESC', SCRAM 'F1', or Rod Height 'R0'.
Also consider using Emergency Cooling 'E100'.
Warning (Yellow) Point: Reactor core temperature above
750F.

could result in localized boiling and fuel element failure.
Use Emergency SCRAM 'ESC'.
Warning (Yellow) Point: Reactor pressure below 2 X Reactor
temperature.
Danger (Red) Point: Reactor pressure below 1.8 X Reactor
temperature.
03

the reactor core is in danger of becoming uncovered. Use
Emergency Cooling 'E100', or Make-up Feed to Primary 'M100
DP'.
Warning (Yellow) Point: None.
Danger (Red) Point: Reactor coolant level below 100%.
04

tely inserted.

This alarm indicates above normal radiation levels in the
containment building. This may be due to normal continuous
high power operation or to fuel element failure. No im-
mediate action necessary.
Warning (Yellow) Point: Radiation level above 200 Milli-
rem/hour.
Danger (Red) Point: Radiation level above 500 Milli-
rem/hour.
06
Press Lvl - Pressurizer Level
This alarm indicates that the pressurizer level is out of
specification. A level too high will result in a pres-
surizer failure and primary coolant leakage. Pressurizer
level too low will result in pressurizer heater failure and
loss of pressurization to the reactor. Control level with
Primary Drain Valve 'F2' and Make-up Feed 'DP'.
Warning (Yellow) Point: Pressurizer level above 85% or
below 50%.
Danger (Red) Point: Pressurizer level above 90% or below
45%.
07
Pri Flow - Primary Coolant Flow Rate
This alarm indicates that the primary coolant flow rate is
out of range. If the flow is too low, the reactor core
receives inadequate cooling. If too high, the primary pump
is overstressed and may fail prematurely.
Warning (Yellow) Point: Primary flow above 90%, or below
.12 X Reactor temperature.
Danger (Red) Point: Primary flow 0.
08
Emerg Low - Low Emergency Coolant Level
This alarm indicates that the Emergency Coolant reservoir
is below safe operating levels.
Warning (Yellow) Point: Emergency Coolant below 25%.
Danger (Red) Point: Emergency Coolant level below 10%.
09
Xchg Temp - High Heat Exchanger Temperature
This alarm indicates that the Heat Exchanger temperature is
exceeding design limits. Action should be taken to reduce
Primary temperature and to increase Secondary Coolant Flow
'S100'.
Warning (Yellow) Point: Heat Exchanger temperature above
495F.
Danger (Red) Point: Heat Exchanger temperature above 500F.
10
Sec Level - Secondary Coolant Level
This alarm indicates low Secondary Coolant level. Make-up
Feed 'DS' should be used to bring the level back to 100%.
Warning (Yellow) Point: Secondary Coolant level below 90%.
Danger (Red) Point: Secondary Coolant level below 50%
11
Sec Flow - Secondary Coolant Flow
This alarm indicates that the Secondary Coolant flow rate
is out of range. Low Secondary Coolant flow can cause Heat
Exchanger failure or Secondary Coolant pump damage. High
flow can result in overstressing the pump.
Warning (Yellow) Point: Secondary Coolant Flow rate above
90%.
Danger (Red) Point: Secondary Coolant Flow rate 0.
12
Cnd In Temp - High Condenser Inlet Temperature
This alarm indicates high condenser inlet temperature.
This can result in damage to the turbine, Secondary Coolant
pump and to the Condenser circulating pump.
Warning (Yellow) Point: Condenser inlet temperature above
275F.
Danger (Red) Point: Condenser inlet temperature above
300F.
13
Cnd Hi Press - High Condenser Pressure
This alarm indicates high Condenser Pressure due to high
condensate temperature or low Secondary Coolant flow. High
Condensate pressure damages the Secondary Coolant pump.
Increase Secondary Coolant Flow 'S100'.
Warning (Yellow) Point: Condenser Pressure above 4 Psi.
Danger (Red) Point: Condenser Pressure above 10 Psi.
14
Cnd Out Tmp - High Condenser Outlet Temperature
This alarm indicates high Condenser outlet temperature.
High condensate temperature causes damage to the Secondary
Coolant pump. Increase Secondary Coolant flow 'S100', or
decrease Heat Exchanger Temperature.
Warning (Yellow) Point: Condenser Outlet Temperature above
195F.
Danger (Red) Point: Condenser Outlet Temperature above
212F.
15
Turb Speed - Turbo-Generator Speed
This alarm indicates that the Turbo-Generator system is not
on design speed of 3,600 RPM. Turbo-Generator overspeed
damages the turbine and generator. Generator Trip valve
'F3' and Generator Field control 'F4' effect Turbo-Genera-
tor speed.
Warning (Yellow) Point: Turbo-Generator speed other than
3,600 RPM.
Danger (Red) Point: Turbo-Generator speed above 3,636 RPM.
16

Coolant, Condenser Circulation, Lube Oil, Emergency Cool-
ing, and Make-up Feed.

Cntrl Warn - Control/Auxiliary Power Warning
This alarm indicates loss of auxiliary power or an error
detected by the automatic control system. Loss of aux-
iliary power results in failure of all pumps and controls
if the generator is not producing power.
