(6) Where possible, equipment and accessories shall
be commercial grade or as nearly so as practicable. Finishes and toler-
ances most certainly can be commercial grade, with inspection and clean-
ing held to a minimum over that normally required for power plant
(7) A thorough study is required of all probable
modes of operation to cover future pipe connections, instrumentation ac-
commodations, equipment manipulation, sampling arrangements, etc.
The following series of experiments will be performed
for each of the various cores and for every significant modification to each
of the cores (i.e., modifications involving variations in flux and/or power
distribution, void coefficient, size, and orificing). Each individual experi-
ment would involve adjustment of the required parameters to their desired
values and measurement of the power level and/or system response as re-
quired. All other available information, such as that concerned with in-
ternal temperatures, pressures, flows, entrainment, carry-over, water
decomposition, radiation levels, etc., if available, and if significant, would
The experiments may be divided into three primary
groups. The first group would be pursued in order to determine the
characteristics of the reactor operating as a steady-state steam generator
and the limits of its stability as affected by the pressure, coolant flow, and
subcooling. The second group would involve investigation of the response
of the reactor to the type of steam flow, water flow, and subcooling tran-
sients which will occur when the reactor is a part of a power-generation
system. The third involves observation of the performance of the system
when various types of control methods are employed to eliminate unde-
sirable reactor response to variation in power demands.
Specifically, suggested experiments in the groups are:
(1) Steady-state operating characteristics (determi-
nation of power density vs. reactivity in steam voids up to limiting power
(a) Pressures of 600, 800, 1000, 1250, 1500,
(b) Subcooling equivalent to non-boiling lengths
approaching 0% and 100%, in 10% increments.
(c) Flows of 7500, 10,000, 15,000, 20,000, 27,500,
35,000 gpm for 4-ft diameter cores and in-
cluding lower rates for cores of smaller
