Total dosimetry for the ten year outages of Units 2-4 and 5 carried out in 1990-1991 at the Bugey Nuclear Generating Centre

The French regulation imposes a very important revision for pressurized water reactors which must be carried out every 10 years. Altogether, all the interventions on the primary and secondary circuits represented 800,000 hours of work for each unit. Total dosimetry varied from 3.45 Sv for Bugey 5 to 6.38 Sv for Bugey 2 - these results were very close to the previsions made according to the activity index of the primary circuit. (author)
