System Control and Recorder Panels
a. General Description
The other necessary controls, indicators, and re-
corders not contained at the control console will be contained along the
three wall faces in view of the console operator. The location of each
component, except where specified, will be determined by the Laboratory
at a time when more information relative to size, type and number of
instruments is available.
A multi-point emergency shut-down annunciator,
featuring mechanical reset, will be installed on the central portion of the
control room wall panel. This annunciator shall provide interlock contacts
of a fail-safe variety which may be used for emergency shut-down purposes.
A multi-point standard plant annunciator featuring
electrical reset will be installed adjacent to the above unit. This may take
the form of several annunciator cabinets, in order to provide sufficient sta-
tions conveniently, but all cabinets shall have common reset and audible
alarm features as described below.
The annunciator panels will be elevated so they are in
view of all points in the control room in front of the panels. They shall be
so arranged that in the event of an abnormality, a horn sounds and a flash-
ing light behind a translucent panel bearing the identification of the ab-
normality is energized. The operator's actuation of a reset button (separate
for shut-down annunciator and plant annunciator) silences the horn and
causes the hitherto flashing light to remain on continuously. When the ab-
normality is corrected, the light again flashes and a bell is heard. A
second actuation of the reset button silences the bell and de-energizes the
flashing light. The sound of the shut-down annunciator horn shall be louder
and easily distinguishable from the plant annunciator horn. The annunciators
shall be wired so that horn and bell are actuated for an abnormality re-
gardless of other stations which are in the reset condition with lights on
c. Nuclear Data Recorders
The nuclear data recorders will be located adjacent to
or below the annunciator panels. These will include:
(1) Three miniature, linear scale strip chart contin-
uously indicating millivolt recorders for power-level trip circuits. The re-
corders will be equipped with high and low-level alarm contacts which can
be set to desired levels for limited indication and shut-down annunciator
operation. Test circuits must also be provided.
