High temperature incore tests of self-powered neutron detectors

  • 1. Atominstitut, Vienna (Austria)

Description

The radiation and temperature behaviour of self-powered neutron detectors was investigated with an incore irradiation furnace constructed at the Atominstitut which allows to test several detectors simultaneously in the temperature range from 100 deg. C to 800 deg. F. The furnace was installed in the central thimble and consists of a Niobium cylinder, a vacuum temperature insulation gap and a second capsule containing the detectors and the resistance furnace. The temperature control is performed by four thermocouples and the temperature is kept constant over the whole temperature range to ±1,3 deg. C. The temperature gradient along the incore detectors does not exceed 2,5 deg. C. With the equipment three different self-powered neutron detectors have been tested incore up to 800 deg. C and the signal deviations caused from temperature and radiation effects have been investigated. The results were compared to other experiments with the same detectors which have been performed in an out core furnace. (author)
