Nuclear Power Plants

The extreme process conditions in Nuclear Power Plants has demanded the use of NICHIAS product technologies.

NICHIAS supplies Wall penetration part sealing materials which are used on walls and floors through which piping and cabling pass - as it has excellent air tightness, water tightnesss and radiation resistance, to metallic heat insulation with lead which is used as a heat insulation material for applications requiring radiation shielding performance as in equipment and piping inside the reactor containment vessel (lead sheets are combined with the metal heat insulation materials), to metallic heat insulation materials used for the pressure container of nuclear reactors in re-circulation equipment, to specialist bellows (flexible expansion joints made of special rubber materials) which are used to seal the clearance between the pipes penetrating buildings, walls and floors and the pipe holes in a nuclear power plant, to specialist gaskets proven in use in the nuclear industry, to re-usable flexible heat insulation materials for the insulation of piping, valves, flanges, etc where the insulation material needs to be able to be removed during plant inspection and maintenance.

Gaskets & Packings
Insulation & Sealing Materials

Gaskets

This expanded graphite tape filler spiral wound gasket is used for pressure vessels, heat exchangers and valves of nuclear power plants. It is designed to cope with the high temperatures and pressures in nuclear power plants, and we control soluble chlorine, fluorine and sulfur in the production process to make it suitable for such plants.

Packings

This packing is suitable for nuclear power plants. The amounts of soluble chlorine and fluorine are controlled in the production process.

Metallic thermal insulation material

This metallic heat-insulating material is used for the reactor pressure vessel, recirculation equipment, and all apparatuses and pipes. It is made of thin stainless steel sheet to prevent corrosion, has high mechanical strength, and can be easily and quickly attached or detached, reducing exposure dose during working.
