The Occupational Radiation Exposure (ORE) for the water primary cooling system (PCS) of the SEAFP was assessed taking into account the first wall/blanket section only. All the potential radiological sources were considered and the analysis was restricted to the most important source at the PCS, the activated corrosion products (ACP). The relevant dose rate was evaluated using the computer code MCNP. Comparison of the results with the respective values measured at the fission PWR plants made it possible to transfer the parameters relevant to the working activities to the SEAFP PCS. Maintenance and inspection were found to be the only working tasks applicable to the SEAFP circuit and the worker access was considered to be allowed 24 b after the plant shut down only.
