Abstract
A pair of adiabatic calorimeters were designed, constructed and applied to the estimation of the dose absorbed by epoxy resin, in a vertical experimental pipe of JRR-4 (swimming pool). One of the calorimeters was made of epoxy absorber, and the other of graphite (carbon). With this pair of calorimeters, the contributions of γ-rays and neutrons to the dose can be separately determined. The dependency of the dose upon the vertical location of the material in the experimental pipe was investigated with the reactor power set at 2.5 MW, and the dependency upon the reactor power was measured in the reactor power range of 0.05–2.5 MW. The calibration of the calorimeter output (V) to absorbed dose (rad) was made with a Fricke dosimeter in a γ-ray field.Keywords
