SN2010-EXTRA. A XENON TRANSIENT DATA REDUCTION CODE FOR THE IBM-650
SN2OlO -EXTRA is an IBM-650 code to reduce xenon transient test data. The code requires an augmented IBM650 with automatic floating-point arithmetic and index registers. Average running time is less than one minute per measurement. A measurement consists of all the data for one rod configuration. During a xenon transient test, the buildup and subsequent decay of the xenon present in the reactor is followed by determining the times that different control rod settings are just critical. The reactivity decreases as the xenon concentration increases until eventually the period becomes negative. BF/sub 3/ detectors follow the change in neutron population. The pulses from the detectors are counted, and the counts plus time and run number are scanned and punched into paper tape automatically. Static data consisting of information and control parameters are recorded manually. The data are converted to reactivity values which are then treated by a linear least square curve fit routine to determine the time of criticality, i.e., when reactivity is zero; and the time rate of change of reactivity. Rod worths are calculated for successive measurements. (auth)
