(b) Heat exchanger outlet temperature - high-
temperature contact for plant annunciator
(7) Primary Make-up Ion Exchanger System (Step III)
Conductivity of ion exchanger discharge.
(8) De-aeration System (Step III)
(a) Flow - as mentioned above, de-aeration flow
from the De-aerating-Hotwell will be
measured by a 24-hr circular chart pro-
portional recorder-controller which will
maintain desired flow by automatic ad-
justment of the flow control valve position.
(b) Temperature of gas entering after-condenser.
(c) Temperature of gas leaving after-condenser.
(d) Temperature of condensate leaving after-
condenser-high-temperature contact for
plant annunciator actuation.
(e) Temperature of gas leaving recombiner.
(f) Other instrumentation as required for
(9) Chemical Shut-down System
(a) Pressure - local indication only. Low pressure
contact for plant annunciator actuation.
(b) Liquid Level - local indication only (gage
Low-level contact for plant annunciator actu-
(10) Core Spray System
Flow into reactor - no indication. A flow detector
actuates plant annunciator when flow into reactor
(11) Emergency Cooling System
(a) Flow into coolers - no indication. A flow de-
tector actuates a common plant annunciator
when flow into either cooler occurs.
(b) Effluent steam temperature - high-temperature
alarm detects water leakage into cooler and
actuates plant annunciator.
(12) Auxiliary Cooling Water System
(a) Auxiliary cooling water effluent temperatures -
high-temperature contacts on all secondary
