A Differential Equation from the Theory of Neutron Thermalisation

The heavy gas model using a synthetic kernel leads to coupled equations for the determination of the neutron flux in a bare reactor. The very special problem of solving analytically the defining equation for the energy dependent neutron flux in a region for which there are no source terms is considered. (auth)

Use of a Radioisotope Method to Measure Flow in the HIFAR Light Water Cooling Circuit (open access)

Use of a Radioisotope Method to Measure Flow in the HIFAR Light Water Cooling Circuit

A radioisotope method has been used to measure the flow in the light water circuit of HIFAR. A mean value of 756 pounds/sec was obtained which is in fair agreement with conventional Dall tube method. Attempts to measure the flow through individual cooling towers were not entirely successful, but some useful information was obtained.

Measurement of the Prompt Neutron Lifetime in HIFAR (open access)

Measurement of the Prompt Neutron Lifetime in HIFAR

The reactor transfer function of HIFAR has been measured at low power and compared with the calculated response determine the prompt neutron lifetime. Lifetime values in the range 600 to 800 microseconds, depending on the position of absorbers withing the core and reflector , were obtained with an estimated error of less than 100 microseconds.
