Package design

Designing and testing packages to transport a wide range of nuclear materials by sea, rail and road.  

Our extensive and unique expertise in nuclear transports includes the design of packages to safely contain material and demonstrate compliance with relevant national and international regulations. 

Over the past 40 years, we’ve helped customers securely package and move nuclear material for many different purposes – nuclear power generation, nuclear facility decommissioning programmes, hospital waste arising from diagnostics and treatments and other industrial processes. 

Scoping requirements

Each movement of nuclear material is often a unique challenge. Ensuring material is packaged securely not only protects people but also the environment in which it is being transported. No matter how big or small the challenge, we work closely with our customers to understand the full scope and implications of their needs.  

Regulatory, technical and stakeholder considerations are inherent in specialist nuclear transports. No two projects are ever the same, which is why we concentrate time upfront to get the full picture of the complexities so we can address them all, one at a time. This is essential for devising the right solution. 

NTS works closely with customers to understand the full scope and implications of their individual packaging needs. From this in-depth assessment, we then develop and design the best solution. 

Package design flexibility

Our team of engineers are experts in adapting existing packages, developing or modifying package components or, if required, design and engineering bespoke transport packages for a customer’s particular needs.  

NTS experience covers the complete range of flask designs for different materials, from sealed sources, fresh uranium and MOX fuel to spent fuel and high-level waste. We can also self-certify packages up to Type A classification. 

When customers procure a nuclear package from NTS, they are accessing decades of experience working with competent authorities, and different stakeholders to ensure it is suitable for their needs.
