Seminar on

Decommissioning of nuclear facilities

Studsvik, Nyköping, Sweden
14 – 16 September 2010

A Nordic Nuclear Safety Research (NKS) seminar organised by Studsvik Nuclear AB (Studsvik) and Swedish Nuclear Fuel and Waste Management Co (SKB).

A seminar on the theme “Decommissioning of nuclear facilities” will be arranged in Studsvik, Nyköping, Sweden, 14-16 September 2010. The seminar is sponsored by NKS and arranged by Studsvik and SKB.

The abstracts sent in have been reviewed by three working groups and a complete, but so far preliminary, program has been established (see below).

The seminar consists of three sessions, external presentations and study visits at the Studsvik site. The external presentations are made initially by representatives from IAEA and OECD/NEA. The subjects for the three sessions are Decommissioning and dismantling, Free release and radiological survey, Waste management and final disposal respectively.

Use the link to the right for a complete invitation.

Please, use the link to the right to register. The registration shall be done before July 2^nd.

Please, contact Anders Appelgren if you have some questions about the seminar. Anders can be reached on +46 155-22 12 57 or anders.appelgren@studsvik.se.
