Abstract : The barometric coefficient of a reactor has been determined in the past by following the change in reactivity due to variations in atmospheric pressure. These changes are normally small and it has therefore been difficult to obtain an accurate measurement of the barometric coefficient. For this reason, it was decided to use the reactor fans to simulate the barometric effect. By sealing the inlet air ducts and operating one or more fans a uniform pressure drop ranging from 15 to 53 mm Hg could be maintained over the reactor. These pressure changes are much greater than would be provided by the most severe weather conditions.
