An air sampling system to estimate concentrations of argon-41 in the V.P.I. physics building during reactor operation
A gamma scintillation spectrometer was assembled. and calibrated in a low background radiation area to analyze air samples. Air samples were taken from different locations in the physics building during reactor operation to determine the concentrations of A⁴¹ released to the surroundings of the …

Neutron radiographic methods
… different specimens including low Z materials and heavier materials such as iron have been used as test objects. The effects of alternate methods of obtaining the radiographs and of the different experimental parameters have been studied. Quantitative investigations were made of the effects of …

A study of the reactivity effects of the V. P. I. nuclear reactor
Once a reactor is critical and at a constant power level, the net reactivity at any time is zero. The major contributions to changes of reactivity in the V.P.I. Argonaut reactor are: 1) Fuel and coolant temperature changes 2) Graphite temperature changes 3) Xenon poisoning The control rods have to …
