The reactor scrams are summarized in a table which identifies the component.that opens the safety circuit and the reason or cause for the safety circuit trip. Caution should be exercised in the use of the summary for specific analysis of reactor scram causes. In a high percentage of cases, the component that opens the safety circuit is not at fault. A description of the reason or cause for a particular scram is given in the body of the report. The actual outage time charged to the cause of the reactor scram is given with the exception of scrams caused by tube leaks or fuel failures.

Expressions are presented for the electric and magnetic fields due to a pulse of charge, which may be oscillating transversely while moving down an infinitely long highly conducting pipe of circular cross section. The expressions are evaluated at large distances from the pulse and the fields are shown to decrease algebraically in the distance behind the pulse. In the absence of transverse oscillations the longitudinal electric field varies as the inverse three-halves power of the distance; in the presence of oscillations the dominant field component is the transverse magnetic field, which decreases as the inverse one-half power. In the long-range limit the amplitude of the fields is proportional to the square root of the wall resistivity. The phase of the field associated with the oscillating pulse is shown to be the phase of the pulse at the time when it passed the point of observation.
