Abstract
The TK.-6 spent fuel flask (Figure 1) is used to transport spent VVER-440 fuel in Russia and some of the countries of Central and Eastern Europe and Finland. It has been in use since 1979 and is currently operated as a Type B(M) package. As part of its T ACIS Programme (Technical Assistance to the Commonwealth of Independent States) the European Commission is supporting a detailed review of the TK.-6 flask design, against the 1985 IAEA Regulations (IAEA, 1990). The work is currently being carried out by Ove Arup & Partners, with VNIPIET and AEA Technology as sub-contractors. This paper describes the TK-6 flask design and operating conditions, and presents the results of some of the assessment work completed to date.
