Inventory of radioactive waste and spent fuel. Edition 2004

Since it was founded, ENRESA has drafted and updated an inventory of radioactive waste in Spain, based on the data received from the producers of this waste. Initially, a study was made of the situation at 1 January 1986 regarding the main producers generating radioactive waste, using the resources available with a view to preparing the first draft of the 1st General Radioactive Waste Plan. Subsequently, with the collaboration of the electricity companies, hospital and research centres, industrial companies using radioactive isotopes, etc. our detailed knowledge of the situation has improved. This has enabled us to elaborate strategies and management programmes with greater precision. In order to facilitate the availability of data, computer based systems have been developed which allow information on the situation to be collected instantaneously for use in short and medium term projects, which in turn facilitate long term predictions. This document constitutes a synthesis of the radioactive waste inventory based on the information available to ENRESA. The inventory is basically intended to provide information on the volume of the waste which was stored at each installation as of 31 December 2004, as well as providing a forecast of future waste generation for all producer installations and, consequently, supplying data on the total inventory of waste to be managed in Spain. Nevertheless, it should be pointed out that the values for forecasts given in this report are based on the experience of ENRESA and on studies carried out, and it was decided to round off the values. Therefore, this data may not match other data given in the past or at a possible future data. After describing the classification of radioactive waste to be managed, chapter 3 of this document lists and briefly describes the radioactive waste producers and the main characteristics of the waste generated. Chapter 4 contains the inventory of radioactive waste, focused on the type of producer, including the inventory of the Disposal Facility at El Cabril, which, due to the mission entrusted to it, is responsible for providing information on the current stock of waste and the forecasts of waste to be received in the future, and the waste currently stored in foreign installations which, in time, will be returned to Spain as it had been waste treated in Spain and then Exported to these installations abroad. Chapter 5 of this document summarises the data given in the previous chapters, providing an inventory of each of the types of waste which require a differentiated management process. This chapter also refers to the situation on 31 December 2004, as well as the inventory for each type of waste which will have to be managed in Spain in the future. Finally, it should be mentioned that in the 2004 inventory, it was decided not to include contaminated material stored temporarily in the nuclear power plants where a management process had not yet been decided on with regard to classification as radioactive waste. Moreover, contaminated liquid waste or suspension of ion exchange resins which are stored in nuclear power plants, awaiting conditioning as LILW package pieces, were not included in this study. And lastly it should be stressed that fuel elements which are irradiating in the reactors of the nuclear power plants have also been excluded from this study. (Author)
