Handling of Spent Nuclear Fuel and Final Storage of Vitrified High Level Reprocessing Waste. 4. Safety Analysis

摘要

The report is a safety analysis on the management of high-level radioactive waste from reprocessing of spent fuel. The work is part of the Swedish KBS-project. Handling, storage and transport will be done in accordance with international and national rules. Management and storing of vitrified high-level waste will be done according to the principals tested in the Marconle plant in France. The probability of the most severe accident, a ship collision with fire, is calculated to 3 . 10 exp -6 per year. If this will occur near a big city the maximal collective dose is about 30 000 manrem. This means that a maximum risk of 6 cases of radiation induced cancer occurs. For the most severe case concerning final disposal, a deep-well with drink water near the final storage, the individual dose is calculated to increase in the future by mostly 0.4 rem for 30 years, which will be reached after about 200 000 years. This is less than the variations of the natural radiation. (Atomindex citation 09:408911)
