OVERVIEW

Linking global infrastructure to critical operations

Prysmian Group delivers a complete portfolio of superior nuclear cables for systems and components involved in the production of nuclear energy, including medium-voltage, instrumentation, control, communication, fiber optic and cables for special radiation-monitoring equipment.

Quality and performance guaranteed:

  • A wide range of state-of-the art cables for existing and new power stations
  • Designed and third-party approved solutions in accordance to main environmental standards and design requirements
  • Performance and reliability over time (up to 60 years)

ULTROL® 60+ cable solutions for Generation III+ and Legacy nuclear power facilities

ULTROL® 60+ cables deliver reliable low- and medium-voltage power for efficient power production, distribution, control and communications in nuclear facilities. For optimized operation in all known reactor environments from inside and outside containment, to the turbine island and balance of plant, ULTROL 60+ cables meet flame testing and long-term thermal endurance to exceed 60-year service life for GEN III+ and legacy reactor profiles.

Founded on a legacy of over five decades of dedicated manufacturing excellence, our nuclear quality assurance program is compliant with 10CFR50 Appendix B, ANSI N45.2, ASME NQA-1 (1994 and 2008/9), ISO 9001. Extensive third-party qualification testing ensures that every ULTROL 60+ cable conforms to industry standards, as well as your specific needs. Our committed R&D, manufacturing, engineering, quality assurance and sales teams are your valuable resource to satisfy and support your complex nuclear business.

ULTROL 60+ is a step above the rest:

  • Satisfies the most stringent nuclear safety standards for inside and outside containment
  • Conforms to all U.S. Nuclear Regulatory Commission regulations
  • Demonstrates thermal aging and radiation resistance up to 350 MRad exposure levels, proving service life of 60+ years
  • Meets/exceeds loss-of-coolant accident (LOCA) and high-energy line break (HELB) environmental qualification testing per IEEE 323 and IEEE 383
  • Provides excellent wet-electrical (submersion) performance upon aging at 90° C over two years
  • Delivers reliability in extreme conditions (cold/hot temperatures, humidity, abrasion, fire performance in emergency, etc.)
  • Offers tougher abrasion-resistant, flame-retardant Cross-linked Polyolefin (XLPO) jacket compound

As one of the first radiation- and moisture-resistant cables with flame-retardant insulation to guarantee a 40-year service life, the ULTROL® name has been synonymous with reliability and safety in nuclear cable for nearly 40 years. Backed by a continued commitment to provide the nuclear industry with cable solutions that deliver maximum service life, Prysmian has extended ULTROL’s demonstrated quality and performance with its latest mastery of technology—ULTROL 60+. Based on a combination of ULTROL’s original renowned technology and Prysmian’s industry-leading R&D, processing capabilities and decades of nuclear experience, ULTROL 60+ features a unique balance of highly engineered insulation and jacket compounds coupled with high-grade copper conductors that ensure reliable electrical performance and superior durability under all operating conditions. Proven to meet the most rigorous Generation III reactor requirements for a 60-year operating life and beyond, ULTROL 60+ is ready to support the modernization and construction of pressurized and boiling water nuclear power plants worldwide.
