Nuclear Marine Applications

Small nuclear reactors power over 500 maritime vessels worldwide in order to be at sea for long periods without refueling. Many are submarines, but also included are other vessels ranging from civil icebreakers to aircraft carriers – all carrying out important duties in making sure global maritime operations are conducted in a safe and efficient manner.

In order to control the reactor, cable penetrations are installed to safely conduct electricity and data signals through the fire-protective, pressure-resistant and hermetically-sealed walls of the bulkhead compartment. In case of an accident, these components play an especially critical role by helping prevent steam, pressure and radioactivity from escaping.

The vital purposes of these specialized vessels, the fact that the lives of the crew depend on their safe operation, and the dangers inherent in a nuclear reactor underline the importance of product safety and quality for nuclear-powered ships and submarines. SCHOTT Eternaloc® components help keep the seas safe and support the daily operations of vessels all across the world.

Uncompromising quality standards combined with leading engineering know-how have made SCHOTT the first choice as a cable penetrations supplier for nuclear-powered ships and submarines.

A SCHOTT Eternaloc® Electrical Penetration module for nuclear-powered ships and submarines consists of:
  • A metal housing with sealed-in conductors
  • Two glass-to-metal sealed barriers (utilizing compression sealing techniques)
  • Mating connectors, cabled according to customer specifications on demand
In addition to producing components for naval vessels, SCHOTT can supply Eternaloc® nuclear penetration assemblies for floating nuclear power plants used in the supply of power to remote places. Integration of glass-to-metal sealed nuclear EPAs into these systems helps deliver the same level of safety and maintenance-free performance found in traditional nuclear power plants and nuclear-powered vessels.
