(8) Condenser By-pass Steam Flow - The flow of
steam through the hotwell by-pass will be measured and indicated in the
control room on a multipoint flow indicator.
(9) Hotwell Pressure - Hotwell pressure will be meas-
ured and continuously recorded on a 24-hr circular chart proportional
recorder-controller. This signal will control the position of the condenser
by-pass steam flow control valve S9. The controller will have adjustable
control point and band width, and high and low alarm contacts to actuate the
(10) Hotwell Temperature - Hotwell temperature will
be measured and indicated in the control room on a multi-point temperature
(11) Hotwell Level - Hotwell level will be measured by
a differential pressure device and continuously recorded on a 24-hr circular
chart proportional recorder-controller. The controller will have an ad-
justable set point and band width and will be used to control the make-up
water flow control valve. High and low level alarm contacts will be pro-
vided to actuate the plant annunciator.
(12) Hotwell De-aeration Flow Rate - The rate of flow
from the hotwell vent line will be continuously recorded on a 24-hr circular
chart proportional recorder-controller, which will maintain desired flow by
adjustment of flow control valve position. Adjustable set point and band
width are required.
(13) Reactor Feed-water Flow Rate - The rate of feed-
water flow will be measured by means of an orifice. This signal will be
continuously recorded on a linear chart proportional recorder-controller.
This signal, coupled with reactor water level and total steam flow, com-
prise the standard three-element feed-water control system.
(14) Reactor Feed-water Temperature - The reactor
feed-water inlet temperature will be measured at a point on the feed-water
line as close to the reactor vessel as possible. This signal will be indicated
on a multi-point temperature indicator.
(15) Forced Circulation Water Outlet Subcooling - The
differential between the reactor temperature (2 above) and the individual
reactor coolant outlet lines (close to the vessel) will be measured and indi-
cated on a multi-point differential temperature indicator.
(16) Forced Circulation Water Inlet Subcooling - The
differential between the reactor temperature (2 above) and the reactor
coolant inlet temperature will be continuously recorded on a linear scale
strip chart recorder. This signal is for multi-purpose control and will go
to the Jack Board.
