There are no nuclear power stations and no nuclear fuel cycle activities in Ireland. There are 2.5 tonnes of natural uranium in storage on the campus of a university, which was previously incorporated in a sub-critical assembly. This material is stored in the building in which it was previously used. Other than in relation to these uranium sources, the application of the Convention is limited to radioactive waste arising from the medical, industrial and research applications of radioisotopes.

This Report gives an outline of Ireland’s national policy, State institutional framework and general legislation governing all aspects of the implementation of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management in Ireland. It also sets out measures adopted to implement the relevant obligations of the Convention noting that Ireland does not have any spent nuclear fuel to deal with.

Ireland became a member of the International Atomic Energy Agency in 1970. In March, 2000, Ireland was the 25th State to ratify the IAEA Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, thus bringing the Convention into force.

Posiva Oy is studying the Finnish bedrock for the geological disposal of spent nuclear fuel. The study is based on the site selection research programme started originally in 1983. The programme is in accordance with the decision in principle by the Council of State in 1983 and aims at the selection of one site in 2000. Four sites, Hastholmen in Loviisa, Kivetty in Aanekoski, Olkiluoto in Eurajoki and Romuvaara in Kuhmo, have been studied in detail. This report summarises the results of the site investigations carried out at Olkiluoto.

The report outlines the current design and safety concept for the planned repository. It summarises the approach used to formulate scenarios for the evolution of the disposal system over time, describes these scenarios and presents the main models and computer codes used to analyse them. It also discusses compliance with Finnish regulatory requirements for long-term safety of a geological repository and gives the main evidence, arguments and analyses that lead to confidence, on the part of Posiva, in the long-term safety of the planned repository

This second version of the Olkiluoto Site Report, produced by the OMTF (Olkiluoto Modelling Task Force), updates the Olkiluoto Site Report 2004 (Posiva 2005) with the data and knowledge obtained up to December 2005.<br/>The main product of the modelling has been to develop a descriptive model of the site (the Site Descriptive Model), i.e. a model describing the geometry, properties of the bedrock and the water and the associated interacting processes and mechanisms.
