Certain parts of the new nuclear reactor and associated technologies are designated as ‘Long Lead Items’ (LLIs) as they take a significant amount of time to manufacture and are needed early in the construction phase. They therefore need to be ordered well in advance of nuclear construction beginning on site and in order for Wylfa Newydd to start generating in the first half of the 2020s.
To enable this process to begin Horizon has signed a Deed with ONR to give the regulator oversight of Horizon’s procurement activities for the LLIs, which includes the reactor pressure vessels, in advance of Horizon applying for a full Nuclear Site Licence at Wylfa.
Janet Wilson, Licensing and Permitting Director at Horizon said: “This is a significant milestone for Horizon as it marks another step in our journey towards becoming a Nuclear Site Licensee and the construction and operation of Wylfa Newydd. The Deed is a sign of how we have grown and developed as an organisation over the last few years and we look forward to strengthening our working relationship with the ONR still further as our project advances.”
Under the Deed, Horizon will inform ONR of its schedule for procurement and make documents, activities, and premises relating to the procurement of LLIs available for inspection. Horizon will also work with the regulator to ensure that all procurement activities for the LLIs are in compliance with the ONR‘s standard licence conditions.
