概要
The sealing material of the containment vessel has been adopting improved EPDM rubber instead of silicone rubber from heat resistance, steam resistance, radiation resistance at severe accident. In order to evaluate the sealing performance of the improved EPDM rubber (EP-176), the steam seal test was conducted under a severe environment than the currently assumed severe accident. For the improved EPDM rubber (EP-176), we have found that the limit of sealing performance as O-ring is 300 ° C, 336 hours or more.
