Project summaryAs in all republics, a point of burial was organized for radioactive waste (RPBRW) in Tajikistan. After the collapse of the USSR, the centralized service fell into a state of disarray. The situation with RPBRW was aggravated as a result of the civil war in Tajikistan.
A republican point of burial of radioactive waste is located in the Fayzabad region of the Tajikistan Republic, 40 km from Dushanbe. The RPBRW is situated in a zone of high seismic activity. The burial place contains both liquid (LRW) and solid (SRW) radioactive waste.
Two burial places were removed from operation in the beginning of the 1990s. It is a filled burial place of solid radioactive waste and a burial place of liquid radioactive waste.
Questions of the protection RPBRW have now become especially topical because of a reduction in financing, as there is a threat of possible infiltration for terrorist activity.
At the same time, unsatisfactory condition of containers (for LRW) could result in radioactive penetration into ground water.
The purpose of the project is the complex inspection of the RPBRW and the development of measures for its rehabilitation.
Here, a study of documentation will be conducted and a radioecological inspection performed on the RPBRW and the area within its vicinity. Special attention will be given to the possible leakage of radioactive liquids and to paths of migration of mobile nuclides.
LRW will be studied.
The sorption properties of local ground, bentonite clays and industrial cationites will be investigated and their characteristics will be compared.
On the basis of the obtained data, a means will be developed to transform LRW to solid phase for subsequent burial, along with methods and instrumentation for clearing LRW containers.
At the same time, a means to preserve SRW burial places will be developed.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
