1 safe and reliable cable solutions for the world's nuclear industry Nuclear viability . Recent years have seen a (GCR), a Liquid Metal renaissance of nuclear power Fast Reactor (LMFR), worldwide. There are some or Accelerator-Driven System 435 nuclear power reactors (ADS), you are also looking in operation which account for to improve performance, 14% of the world's electricity, while lowering construction and 30% within the European and operating costs. Union. New reactors are being built in China, India, That is where custom-designed, Japan, the Russian Federation, nuclear-qualified cables play South Korea, France, Finland, an important role by providing Slovakia, Romania and Bulgaria.

However, to win wide of-the art cables for public acceptance, nuclear existing and new projects power has to be perceived as being absolutely safe , o ptimized operation, under all conditions and maintenance, and power far into the future. plant life management (PLIM). p roven solutions adapted As a nuclear power plant to national standards authority or operator, and requirements you not only expect new plants to achieve new levels of safety p erformance and and reliability, you are currently reliability over time revamping existing plants to (up to 60 years).

Whether you are attack, emergencies running a light-water reactor and natural catastrophes (Pressurized Water Reactor/. rapid response to technical PWR, French EPR/European requests and a long-term Pressurised Reactor, Russian supply of replacement cables VVER, or Boiling Water Reactor/BWR), a heavy-water R&D knowledge and support reactor (advanced CANDU for plant extension and type), a Gas Cooled Reactor, upgrades requires safe and reliable cables Nexans nuclear cables A complete range of cables help assure a clean source for quality and performance of economical energy reliability in extreme hot/cold, for coming generations.
