Abstract

Abstract

In order to guarantee the fire safety of nuclear power plants, we have studied the radio resistance of two kinds of fireproof materials—the cable fireproof coating and organic fireproof putty, which are widely used in nuclear power stations. The results indicate that the γ-ray over 1000 kGy can seriously deteriorates the bending-resistance performance, the wet-resistance and heat-resistance, the cold-resistance and heat-resistance performances of the cable fireproof coating. The γ-ray over 500 kGy not only possess great effects on the corrosion performance of the organic fireproof putty but decreases the fireproof capability greatly.
