What Are Nuclear Casks?

Nuclear casks are specially engineered containers designed to safely contain and transport radioactive materials. These heavy-duty enclosures are constructed to withstand extreme environmental conditions, radiation leakage, mechanical shock, and fire. Casks are essential components in nuclear operations, ensuring the containment of radiation and preventing environmental contamination during storage or transit of high-level waste, spent nuclear fuel, or sealed radioactive sources.

Key Features of Nuclead Nuclear Casks

Radiation Shielding

Our nuclear casks are manufactured using dense, lead-lined structures that effectively shield against gamma and neutron radiation. The lead used in our casks is refined to meet strict purity standards and engineered to deliver optimal shielding in compact dimensions.

Robust Construction

Each cask is built with multi-layered protection, including inner containers, radiation-absorbing liners, stainless steel exteriors, and neutron shielding where needed. These layers are designed to withstand extreme temperatures, impact, corrosion, and mechanical stress during transport or long-term storage.

Sealed and Secure Closure

Nuclead nuclear casks feature precision-engineered seals, locking systems, and gaskets to ensure a leak-proof, airtight environment. This guarantees that no radioactive materials or gases escape into the surrounding area under any condition.

DOT and NRC Compliance

All Nuclead nuclear casks are fabricated to meet U.S. Department of Transportation (DOT) and Nuclear Regulatory Commission (NRC) standards, including 10 CFR Part 71 regulations. For international shipments, we also accommodate IAEA packaging standards and export requirements.

Applications of Nuclear Casks

Spent Fuel Transport

Nuclear power plants require robust, shielded casks to transport spent nuclear fuel from reactors to storage facilities or reprocessing plants. Our casks are certified for this task and can be custom-designed for different fuel assemblies, whether PWR or BWR.

Long-Term Waste Storage

Nuclead casks are widely used for the interim or long-term storage of radioactive waste, including transuranic waste, high-level waste, and contaminated equipment. Their durability ensures safe containment for decades.

Isotope Shielding and Delivery

Medical and industrial isotope producers use our compact nuclear casks to shield and transport radioactive isotopes used in imaging, cancer therapy, oil exploration, and quality control.

Research Applications

Universities and research labs trust Nuclead nuclear casks for the secure containment of irradiated materials, experimental fuels, and radioactive samples during experiments or storage.

Government and Defense Use

Military agencies, homeland security units, and national labs depend on our nuclear casks for secure movement and storage of nuclear materials related to energy, defense, and non-proliferation programs.

Custom Nuclear Cask Fabrication

Design Flexibility

Nuclead offers a full range of custom nuclear cask designs based on your shielding requirements, radioactive load, transport method, and regulatory constraints. Whether you require cylindrical casks for reactor fuel rods or compact isotope flasks, we tailor every solution.

Lead Lining and Casting

Our facility can fabricate lead-lined casks in varying thicknesses depending on shielding needs. The lead is bonded to steel or alloy exteriors using advanced casting and welding processes to ensure integrity and long-term reliability.

Materials and Construction

We use only the highest-grade materials, including:

• Pure lead or lead alloys for internal shielding

• Stainless steel or carbon steel outer shells

• Neutron-absorbing materials such as borated polyethylene

• Silicone or Viton gaskets for high-temperature seals

Optional Components

Customers can request additional features such as:

• Shock absorbers

• Remote-handling mechanisms

• Temperature monitors

• Venting and filtering systems

• Forklift or crane lifting points

The Importance of Safe Cask Design in the Nuclear Industry

The role of nuclear casks in the nuclear fuel cycle cannot be overstated. As the demand for nuclear energy and radioisotopes continues to grow, so does the need for safe containment of materials that pose significant radiation risks. Proper shielding and secure containment help protect workers, the public, and the environment from radiation exposure while enabling the safe expansion of nuclear technology.

Cask design must account not only for the shielding of ionizing radiation but also for containment under extreme conditions such as fires, collisions, and water immersion. This is why Nuclead’s engineering approach emphasizes multi-layered protection, quality-tested materials, and a commitment to safety in every product we build.
