Examples of Implications of Different Planning and Characterization Strategies on Costs: French Reactor Siloé. Appendix IV

The Siloé facility is an open pool type research reactor built in France in 1961 by the French Alternative Energies and Atomic Energy Commission (CEA). Located on the Grenoble site, it has been used mainly for fundamental research experiments, production of radioisotopes for medical use, materials testing and production of spiked silicon for industry. The reactor started operation in 1963. With an initial operating power of 15 MW, in 1967 it increased to an operating power of 30 MW and in 1972 to an operating power of 35 MW. In December 1997, the reactor was shut down and the post‑operational cleanout phase began, lasting until 2005. On 26 January 2005, the Nuclear Safety Authority authorized the CEA to permanently shut down the facility in order to start dismantling activities. The dismantling strategy is immediate dismantling through to release conditions, with reuse of the buildings.
