Supporting Exceptional Material Durability and Stability
Nuclear applications subject materials to conditions found nowhere else in engineering — sustained neutron bombardment, extreme thermal cycling, corrosive coolants, and the mechanical stresses of high-pressure containment. Material failure is not an option.
Goodfellow supplies the high-purity metals, alloys, ceramics, and polymers that nuclear engineers specify for these environments, from zirconium alloys for fuel cladding to MACOR® for reactor fixtures — available in research quantities through to production volumes, with no minimum order.




Material Challenges in Nuclear Fusion Reactor Design
Nuclear fusion reactors place radically different demands on materials depending on where they sit in the system. Steam pipes, control rods, fuel cladding, condensers, and reactor housings each operate under distinct combinations of temperature, pressure, fatigue, and corrosion conditions — requiring precise material selection for every application.
Fusion also presents a fundamentally different radiation challenge to fission. The radiation produced decays significantly faster, making it more manageable — but the materials must still withstand intense neutron flux during operation.
Goodfellow has direct experience supporting engineers and researchers through material selection for fusion reactor design and construction. In 2022, the Lawrence Livermore National Laboratory achieved a historic milestone — producing more energy from a fusion experiment than was put in — using materials supplied by Goodfellow.
Nuclear Material Qualification and Testing
Meeting the qualification standards required for nuclear-grade materials demands rigorous, accredited validation. Material performance under neutron flux, thermal cycling, and corrosive conditions must be thoroughly characterised before components can be approved for use in reactor environments.
Tensile testing, creep analysis, corrosion resistance, and microstructure characterisation for nuclear-grade materials are available through our ISO/IEC 17025-accredited materials testing laboratory.

Technical Solutions and Services
Working as your experienced partner in the nuclear fusion sector, we can find and supply the highest quality materials for your products. Our nuclear energy applications and innovative alloys can help you achieve unparalleled performance and better energy efficiency in building and plant design.


Alloys
Nuclear structures demand alloys that perform under mechanical stress, high temperature, and radiation exposure simultaneously. Vanadium-bearing stainless steels are widely specified for structural components where strength-to-weight ratio matters.
Containment buildings require reinforced steels capable of withstanding blast overpressure and extreme thermal events, while the reactor core itself is surrounded by thick steel shielding as a primary safety barrier.
Goodfellow supplies a broad range of structural and specialist alloys to meet these exacting requirements across every part of the facility.


Polymers
Radiation resistance and chemical inertness make polymers essential in nuclear pipework and sealing applications. PTFE is among the most widely specified — used for pipe coatings, O-rings, and fluid seals where airtight or watertight integrity is critical.
Goodfellow supplies PTFE tubes in a range of diameters to match standard fittings, with a working temperature range up to 260°C, making them suitable for high-temperature steam environments.
Our PTFE materials offer reliable chemical protection for metal pipework throughout the reactor system.


Ceramics
Ceramics are valued in nuclear applications for their chemical inertness, thermal stability, and resistance to radiation degradation — properties that make them effective as protective layers around reactor cores.
Goodfellow supplies MACOR®, a machinable glass ceramic widely used in nuclear power generation for fixtures, reference blocks, and structural components.
MACOR® can be precision-machined to tight tolerances and operates at temperatures up to 1000°C. Custom-machined MACOR® components are available to exact customer specifications.


Zirconium Alloys
Zirconium's low neutron capture cross-section and strong chemical resistance make it one of the most important structural metals in reactor design — particularly for fuel cladding and core components where neutron economy is critical.
Goodfellow supplies zirconium alloys and pure zirconium in a range of forms and thicknesses to suit different construction requirements.
For applications where purity is paramount, we also offer high-purity zirconium grades containing less than 0.01% hafnium, specifically manufactured for nuclear use.
