THE HFETR SPENT FUEL ELEMENTS AS γ RADIATION SOURCE AND ITS USES

This article presents the main results of the radiation research on the spentfuel elements in HFETR. The spent fuel element irradiation facilities and itsmeasurement results are described. It also gives the experimental results on theradiation crosslinking of polyethylene and radiation degradation of polytetrafluoroc-thylene by the spent fuel element irradiation. The value of the spent fuel elementsas γ radiation source for radiation Processing is well demonstrated.
