Finnish Case Study – Finnish Regulations for Decontamination During Operation (International Case Study on Organization and Detailed Technical Aspects of NPP Outage Decontamination)

The following are excerpts of STUK regulations: "A nuclear facility has to have rooms for the decontamination, repair and maintenance of activated or contaminated components and their parts. It is possible to place all systems and equipment that are of essential importance for decontamination in the decontamination rooms. In addition, separate rooms with radiation shielding have to be provided for the decontamination of highly activated and contaminated components. If necessary, it is possible to handle the components and objects to be decontaminated remotely and in a protected manner. Components requiring decontamination have to be identified during plant design. Their transport has to be planned such that their disassembling and transfer for decontamination does not result in significant occupational doses."
