legacy storage facilities with radioactive waste generated resulting from
military programs of the Former USSR remained on the territory of Ukraine
since 70-80s. The transfer of these legacy storage facilities into an
environmentally safe state (remediation) by means of radwaste
retrieval and further management is envisaged in Task 12 of the National Target
Environmental Program for radioactive Waste Management approved by the Law of
Ukraine No. 516-VI of 17 September 2008.
of support implementation of this Task, the Cabinet of Ministers of Ukraine
signed the Implementing Agreement with NATO Support Agency (NSPA) on Radioactive
Waste in the Military Programs of the Former USSR in Ukraine ratified by the
Law of Ukraine No. 526-VIII of 17 June 2015.
project within the Implementing Agreement became retrieval and further
management of radwaste coming from the Vakulenchuk burial in Zhytomyr oblast and the territory
In order to implement
the Pilot Project, the NT-Engineering Company, assigned as the work executor
resulting from the tender results carried out by the NATO
Support Agency (NSPA) in Ukraine, obtained the SNRIU license No. ОВ
001054 of 29 September 2016 for the right for radioactive waste processing
related to radwaste retrieval from the Vakulenchuk burial.
safety assessment of the following documents was carried out under the license
The Technical Decision on Radioactive
Material Relocation from the Vakulenchuk Legacy
Burial to Kyiv Interregional Special Combine, the Safety Analysis Report, the
Program for Radioactive Materials Management implementation of works, as well as other
licensing documents submitted by the NT-Engineering Company.
Resulting from the review, the
license conditions specified the following work stages:
Stage 1 – arrangement of working
environment at the site;
Stage 2 – site planning and creation
of process areas;
Stage 3 – radwaste
retrieval from the burial site and detailed radiation survey of storage
Stage 4 – radwaste
retrieval from the burial building, dismantling of the building, retrieval of
liquid radwaste (if available), backfilling;
Stage 5 – burial site remediation and
radiation survey related to remediation criteria achievement.
retrieved radioactive waste in the form of spent radiation sources from the Vakulenchuk burial and transported it for storage to SSE
Kyiv SISC. The activities related to retrieval and fragmentation of solid
radioactive waste in form of reinforced concrete structures of the facility,
transfer of liquid radwaste pumped from the facility
to solid state through cementing, and transfer of this radwaste
for disposal to Buryakivka RWDS were also performed.
The SNRIU also reviewed and agreed the technical decision on management
of liquid medium revealed in the Vakulenchuk burial released
from radioactive waste that was presented by the Licensee according to the
conditions of the issued license.
The nuclear and radiation safety review of the NT-Engineering
Company documents on Stage 5 implementation:
Selection and Justification of Remediation Criteria of the Area Released from Radwaste at the Vakulenchuk Burial
Site, the of Final Radiation Survey Program, and Technical Decision on Final
Remediation of the Burial Site was performed by the SNRIU under the European
Commission Project INSC UK/TS/48 with involvement of European experts.
exposure dose not exceeding 10 µSv/year for people
who can live in future at- or near the remediated burial site, that complies
with requirements fixed in the radiation safety standards of Ukraine was
established as the basic criterion for the burial site remediation.
The experience gained in
the result of the pilot project implementation will be further considered in
planning, designing and safety assessment under implementation of future projects
on radwaste retrieval from legacy storage facilities
including radwaste generated under the military
programs of the former USSR.
