primary loop and can be done with standard instrumentation.
* An intensive investigation is currently under way to determine the
best means of monitoring primary coolant purity. Details of this
study are covered in Section 4. 6. The target of this pursuit is in-
line continuous monitoring of carbon and oxygen. Provision will
be made for eventual installation of in-line continuous monitoring
instruments even though sampled batch monitoring may be used
at startup.
* Engineering effort will be required for the selection of the neces-
sary instrumentation and transducers required for the primary
and secondary loops to assure that the reactor is adequately and
safety instrumented. The goal is to select transducers with high
inherent reliability to assure continuity of reactor operation.
Redundancy will be used where required for reactor safety consid-
erations on critical parameters.
Tertiary coolant flow and temperature will be monitored by proven
instrumentation. Heat exchanger integrity will be checked by monitoring
for secondary loop reaction products in the tertiary loop. Almost all of
the tertiary loop and miscellaneous instrumentation is standard and requires
little or no development.
Instrumentation for closed loops will be somewhat similar to that
for the open loops in order to standardize as much as practical for ease
of maintenance. However, there is more latitude in locating certain
sensors for the closed loops external to the reactor. Therefore, they
will be more accessible.
Other instrumentation will be required to monitor and some-
times control such items as primary and secondary coolant purification,
building radiation monitoring, vibration, gas purity and pressure, charging
machine position, heating and ventilation, and others.
3. 7. 3 Data Recording, Computation, and Retrieval System
The basic function of the FFTF will be to provide reliable experi-
mental data in an area of new technology. To this end complete records
must be maintained of all reactor operating conditions and all test loop
