A study of the PRTR neutron kinetics and the moderator gas-balance system response to transients was made using analog-simulation techniques. Analytical equations were developed to describe the variables whlch affect the control of the PRTR. These equations were then combined to form mathematical models of the entire system and system components or subsystems. An analog study was conducted on the basis of these mathematical models, utilizing frequency- response techniques to investigate and dcscribe both the subsystems and the entire reactor system. The results which were obtained are presented on standard frequency-response diagrams. The moderator gas-balance teria to the gaus-balance system showed a tendency toward instability. However, disturbing influences of significant magnitude to cause operating difficulty are not believed to be present. Some oscillation of moderator level and power is postulated but this effect may be too small to be measured without special equipment. (auth)
