POWER TRACE ANALYSIS CODES, SNAVELY AND PIP FOR THE IBM-7090
Two programs were prepared for the purpose of obtaining objective statistical information concerring the HRT power trace. The PIP code was used to obtain frequency distributions of power peaks. The SNAVELY program computed the reactivity additions necessary to account for the observed power fluctuations. Frequency distributions were calculated concerning the size and rate of these additions. The behavior of fluid recirculation rates, variation in which could lead to reactivity changes, was also computed. Provision was made for calculating Fourier series coefficients in order to discover pericdicities. Input to these programs consists of reactor power data obthined at equal time intervals. The calculation speed is sufficiently high that over 20,000 values of the power may be processed in a reasonably short time (10 to 15 minutes). (auth)
