SUB ,pNTROL SIGN REVIEW OF P & W
UARTER FOR JULY - SEPT., 1960
Cincinnati 15, Ohio

.''.ANAGER - CONTROL DESIGN
. Last quarter I suggested that the PWAR-llC might be a 10 MW reactor.
This is wrong. The PWAR-l1C apparently is designed for 200 MW
- operation but is expected to be operated at the IET at only 10 MW
but for 1000 hours (p 25). This is particularly interesting from
"""". the standpoint of a promotional scheme.
::::2. A control system mock-up next to an analogue computer is planned
....' at P & W and a "large portion" has been ordered and is scheduled
.;~- for delivery (p 71). This apparently is comparable to what we
planned for the XMA-1.
3. Hardware Status - Third Quarter, 1960:
From the following it is expected that we can estimate where they
stand along a schedule leading to a full-scale demonstration.
Vendor negotiation: drum actuator, motors and harmonic drives,
nutating-disc integrator for turbo pump control (Marquardt?).
Procurement order: syncros for actuators, heat exchanger instru-
mentation, high-temperature, neutron-sensitive ion and fission
Testing: Skinner-type seals, electrical hermetic seals, non-
lubricated bearings, breadboard electrical circuitry, 5000
cycles on limit switch for actuator, development turbo pump
control, thermaleshock tests on fuel nozzles in October, 1960.
