Zusammenfassung:	PURPOSE: EPDM for a nuclear power plant having a mixed reinforcing agent is provided to improve mechanical properties like elongation, tensile strength, etc, and radiation resistance which is stabling effect against oxidant deterioration according to irradiation radiation even in sever environment like accidents. CONSTITUTION: A mixing method of EPDM for a nuclear power plant having a mixed reinforcing agent comprises: a step of stabilizing mixture of EPDM, carbon black, a crosslinking agent, an anti oxidant, a cray reinforcing agent with the weight-mixing ratio of 100:40:1:0.5:10; a step of processing the outcome by vulcanization the mixture for decomposition of the crosslinking agent and for a crosslinking reaction; and a step of irradiating radiation to the sheet, and measuring elongation and tensile strength difference between before and after radiation irradiation by using a part of a sheet as a specimen.
