Spain's Approach to PLiM for LTO

There are eight nuclear units in Spain located in six different sites. All were designed for 40 years of operation. One example is Santa Maria de Garoña (SMG), which reached LTO in 2011. This plant has completed the process and the application required to operate beyond 40 years. The other plants in Spain have not yet applied for LTO, as they will not reach 40 years of operation until the 2020s. The SMG plant is taken as an example of a fully completed LTO application process. In Spain, the organizational structure for PLiM varies widely from plant to plant. Some have a dedicated organization, others do not. The main task in an LTO application is the preparation of an integrated ageing management assessment plan. At SMG, this was developed by a team specifically created for this purpose. A group of 12 specialists from Spanish engineering companies worked for 2.5 years, together with a group of 10 staff from the plant. Experts in the US licence renewal process were also used during the project to assess the work done. The structure of the team that prepared the integrated ageing management assessment plan is shown. After submitting the application for LTO, a new position was created in the plant to manage and coordinate the AMP. In addition, 10 programme owners were nominated to manage the 43 AMPs
