RRFM 2009 Transactions - European Nuclear Society

• Removal of sludge from the SNF storage pool, to be done in spring 2009. Purification
of water in B4 by mechanical filtering is under way since 1996. It will be intensified by
new water chemical control system (WCCS) with ion exchange resin (CGH-8) that is
designed by SRNL, USA and which will be set in operation in B4 by mid-2009;
• Increased physical protection of nuclear material at the site, and
• A work on RS – RF Government-to-Government agreement for repatriation of the SNF
from the RA RR is in progress since November 2003, to be signed in 2009.
3.2 Decommissioning of RA Research Reactor project was initiated after 18 years of RA
RR extended shutdown. Proposal for RA RR decommissioning, based on economical,
technical and legislation reasons, was approved by decisions of the GoRS in summer 2002.
Detail decommissioning plan, including site characterisation, is initiated in 2003 within IAEA
TC project with the aim to select appropriate dismantling and decontamination techniques for
RAW and to obtain all necessary licenses. It is supposed that SNF will be removed from the
site by 2010 and D&D activities will be carried out in period 2011-2016.
3.3 Safe Management of Waste at the Vinča Institute project has to establish the
appropriate organisation structure for LL nad ML RAW management at the site, primarily
during shipment of the SNF, decommissioning of the RA RR and treatment of historical RAW
stored in the ‘Hanger 1 (H1)’. New RAW temporary storage facility (WSF, ‘Hanger 3’, H3) of
large capacity and RAW processing facility (WPF) are under construction and will be set in
operation in Spring 2009. Characterisation of large volume of RAW stored at the H1, it’s safe
repackaging and storage at H3 will be done in parallel with the RAW flow from the RA RR
SNF shipment and decommissioning activities. About 800 m 3 of the liquid LL & ML RAW,
stored at the Vinča site in four stainless steel underground tanks, will be safely conditioned.
High intensity radioactive orphan sources at the Vinča site will be properly treated and safely
stored in a well-protected storage facility within the RAW storage area.
3.4 Radiation Protection project supports fulfilment of above mentioned VIND projects in
aim to provide health physics and medical support, human and technical decontamination,
environmental and metrology monitoring, instrument’s calibration services and emergency
services. Activities of this project are supported by MSTD, EC and IAEA.
4. Conclusion
In spite of the complex structure and dependence of various influences, the VIND Program is
on the schedule, what is important particularly for the SNF shipment project.
