Our Expertise

Without doubt, our biggest assets are our people.

We’re proud to work with so many professional Engineers and Scientists. Thanks to their vast experience and expertise they can deliver innovative packaging solutions time after time. Our technical team regularly provide input to various committees that set UK industry standards, and offer insight when regulations are under review.

Our team consists of a cross section of seasoned personnel who have spent many years within the nuclear industry working directly on nuclear plant and process and have gained a first hand knowledge of what delivering safe solutions means. We also look to the Young Generation Network which allows a unique blend of knowledge and experience to be exchanged between the older and younger generations. Younger people are encouraged to stay and provide a resource for the future.

In recognition of the need for continued improvement, we constantly strive to improve and enhance our training for all our staff. In recognition of this, we have been awarded NEF Assured Nuclear, the industry specific standard for assuring deliverers of training in the nuclear sector. The Independent Advisory Panel recommending the award commended the company for its engagement and drive in ensuring consistency in learning and training development particularly given its size and capacity to deliver. We are the first SME in the nuclear field to be granted the award. The NEF Assured Nuclear Award is recognised by the National Skills Academy Nuclear.

Our training helps us ensure consistency and benchmark against industry standards for training for all staff. The NEF scheme has been specifically developed to assure the quality of training that is delivered ‘in house’ by nuclear organisations, and helps us to enhance our approach to training. It recognises the need for continuous improvement and for training to impact directly on business objectives and highlights performance in six areas: strategy and planning, engagement, design and delivery, innovation, standards and impact.
