Testimonials

George Swalwell

Licensing Engineer, London

 

I am a Licensing Engineer at newcleo, with a background in Physics and Nuclear Engineering.

Working at newcleo has allowed me to accelerate my development whilst working on a genuinely exciting project. I have particularly enjoyed collaborating with the diverse team across the UK, Italy, and France, solving challenging technical problems together as we work on our advanced modular reactor technology. The autonomy and responsibility I have been given to lead on some prominent projects has been extremely rewarding.

I am currently working to towards becoming a Chartered Engineer, supported by my team. My experience has given me a great insight into the wider UK nuclear industry, and I have also been given the opportunity to develop my technical and leadership skills. newcleo provides fantastic opportunities for young engineers, technicians, and financial professionals alike. The team is very supportive, and it is a genuinely exciting time to join the nuclear industry!

Mariacarla D'Orazio

Safety & Licensing Engineer, Turin

 

I am now working in newcleo’s Turin office in the Safety and Licensing team, where I lead many aspects of the lead-cooled fast reactor (LFR) design, including auxiliary systems and the creation of preliminary documents on safety. I joined newcleo after obtaining a degree in Energy Engineering at Politecnico di Torino in 2021, and I have since progressed in terms of both of my professional skills and my projects.

Working with my international peers from UK and France is an exciting challenge. Throughout my time so far at newcleo, I have really appreciated the balance between of autonomy and agency that is encouraged by the organisation on one hand, and the close guidance and support of the management team on the other. This approach to our working culture has really helped me produce valuable work - even when I was a fresh graduate. 

Since joining newcleo, I have had the opportunity to directly apply what I learned from my studies.

I really believe in the power of the technology we are creating, and I feel proud to contribute to the design of our LFRs. I am glad to have had the chance to join newcleo so early on our journey of growth.
