- Insulation Performance of a Cable Insulated with Flame-retardant Ethylene-propylene-diene Rubber Removed from a Nuclear Power Plant under Severe Accident Conditions
抄録
<p>The insulation performance of cables removed from an actual plant was investigated in a simulated severe accident (SA) environment. The cable insulated with flame-retardant ethylene propylene diene rubber (FR-EPDM) was a safety cable in the plant. A similar FR-EPDM-insulated cable was aged artificially to the degree equivalent to what the removed cable would have been suffered. These cables were irradiated with 60Co gamma rays at a dose rate of 10 kGy/h for 50 hours at room temperature to simulate the radiation exposure during a SA. The cables were then exposed to a steam environment for 168 hours to simulate the SA. During the steam exposure, the insulation resistance of the cables was measured continuously. As a result, the minimum insulation resistance was about 108 to 109 Ωm in the two cables, indicating that both have sufficient insulation performance.</p>
