What are the main seals used in nuclear power plants?
Similar to thermal power plants or petrochemical plants.Seal depends on the equipment, in addition to nuclear island equipment, nuclear power and thermal power. Nuclear island equipment seals are also more than a radiation protection requirements.
Nuclear power plants mainly use sealed gaskets, graphite gaskets are used in pipelines, rubber gaskets are used in non-standard equipment. Nuclear grade graphite gaskets require high levels of halogens and sulfur
Rubber gaskets shall consider radiation resistance to ensure that irradiation does not speed up rubber aging. For building joints, sealant will be used to fill the gap.
