You have a critical role to play in providing more environmentally friendly electricity. Nuclear energy is an emission-free, dependable, ‘always-on’ power source which today supplies 10% of global electricity.
Our nuclear cable accessories meet the specific needs associated with protecting many of the 200,000 connections required in the construction and maintenance of your plants. Our nuclear cable accessories have been subjected to the Loss of Coolant Accident Test (LOCA) and High Energy Line Break Test (HELB) to establish their performance in a postulated nuclear accident environment. Our products are designed and manufactured under a quality assurance program that complies with 10 CFR 50 Appendix B and several other national and international standards.
Our Raychem heat shrink components and kits, seal and insulate reliably electrical connections in your nuclear power plants. Manufactured from heavy-wall, flame-retardant, crosslinked polyolefin and precoated with a nuclear grade adhesive, these products are designed to withstand the radiation levels and temperatures found inside the containment buildings of nuclear stations.

One Connectivity Partner
As your critical partner to the nuclear industry, our mission is to support, sustain, and solve your electrical connectivity needs by providing essential components that are compliant with the demanding requirements of US and global regulatory laws.
Our reputation is built on over 40 years of experience in the nuclear market. In fact, our Raychem revolutionary heat shrink technology pioneered radiation crosslinking in the 1950s and has been supplying cable accessories to the nuclear power industry since the 1970s. Today, most safety-related Class 1E splices are made using our Raychem heat shrink components.

Design
In addition to supplying base components (tubing and molded parts), we design and manufacture a wide variety of kits to seal and insulate specific connections in your nuclear plant. These kits have the added advantage of being pre-designed to be consistent with the type-tested designs and contain all the components required for your installation.
Advantages of pre-designed kits:
- Design details and calculations are reviewed and documented
- Multiple checkpoints exist in the documentation to verify proper kit selection
- Traceability is provided and maintained
- Detailed installation instructions provide step-by-step guidance
Qualification Testing
Our nuclear products are designed to perform in extreme environments and are tested beyond the design basis conditions of your nuclear power plants.
Nuclear Equipment Qualification (EQ) for products involves compliance with industry-accepted standards, including IEC/IEEE 60780-323, IEEE 383, and other international standards. The materials used in many of TE’s products have been tested and proven to perform their intended function for the lifetime of the plant typically 40 to 60 years at 90°C. We use many recognized methods to confirm the lifetime, including the Arrhenius method for accelerated aging of plastics. These materials are then used individually as components, as tubing for simple splices, or in various combinations called ‘kits’ that are designed for your complex applications.
Our Class 1E safety-related harsh environment products are type-tested in the intended use configuration and in worst-case conditions by our own or independently certified laboratories. The results of these tests are presented in Energy Division Reports (EDR) which are used for EQ purposes in our certificate of conformance/compliance.
As a recognized manufacturer of the IEEE Nuclear Standards Certification Program, end-users are assured that the equipment qualification testing, reported test results, and regulatory compliance have been verified by an extensive, independent technical auditing team, approved by the IEEE Conformity Assessment Program. This provides confidence and assurance that the products purchased meet all your necessary standards of quality and safety.
Train
We offer training for Raychem nuclear-qualified products to your installers, inspectors, and engineering personnel. These sessions cover the basic elements of material science, heat shrink polyolefin technology, specific product functions, and hands-on installation.
Certification
All our nuclear-qualified products are supplied with a Certificate of Compliance / Conformance.
