Job Description for Defence PIE Technician (Shifts):
UKNNL is where your understanding of reactors fuels the nation. As part of our Fuel Reactor & Reprocessing capability, you’ll play a vital role in developing the UK fuel cycle in line with advances in new technology and new processes. As old reactors reach the end of their lifespan, we need experts like you, with the technical skills to virtually model scenarios that not only enable us to explore new ways of managing the inputs and outputs of reactors, but also pave the way for the implementation of smaller, cleaner revolutionary new reactors. This is a place where you can use your knowledge and expertise to do long term meaningful work for years to come.
The UKNNL Defence teams comprise technical experts, specialists, technicians, modellers and engineers responsible for leading and developing the post irradiation examination of nuclear fuel. This area has a growing workload associated with current programmes, developing workstreams within spent fuel evaluation in support of nationally important programmes, and emerging requirements supporting development of new nuclear reactor technologies.
