8 Containers for disused SRS at the Ukrainian State Corporation Radon specialized enterprises Specialized enterprise Type of container Availability Dniptopetrovsk state interregional specialized combine УКТІВ-120, ПКТ1В-180Н, ПКТ1В- 230, ПКТ1В , ПКТ1Ф-420Н Donetsk state specialized combine ПКТ1В-180Н, УКТ1В Kyiv state interregional specialized combine Kharkiv state interregional specialized combine Odesa state interregional specialized combine Lviv state interregional specialized combine УТА УКТ-І А-60, УКТІВ-80, УКТІВ-100, УКТІВ-120, ПКТ1В-180, КН-4, УТА УТА КИЗ-17, КН-Н, УКТ-І А-100, УКТ-І А- 80 Total УТА ПКТІІА-420Н ПКТIВ-180Н ПКТIВ-230Н

9 DSRS Transportation 4 specialized vehicles has been produced under the US technical assistance 9

10 Storage of disused SRS in welltype storages Storage with the capacity of 20 kg-eqv. Rahas been build and operated since It is equipped with trip, radiation protection systems and alarm system. Containsseveral thousands of sources with total activity approximately 0,3 kg-eqv.ra. Main nuclide- Cs

11 Transport packaging set ПКТІВ- 120Н Transport packaging set is intended for safe transportation and temporary storage of disused closed SRS with isotope 137Cs 60Co. Capacity of loading can of shielding container enables to place up to 1000 retrieved sources. 11

12 Module mobile protective cell for unloading of theblocks SRS, place at the sites of Ukrainian State Corporation Radon Assigned for safe extraction of sealed (enclosed) SRS from the blocks sources of type Э-1/Э-3, Э-1М/Э-4М, БГИ -30, БГИ-45, БГИ-60А, БГИ-75А, БГИ-90А, БГИ-45У, БГИ-60У, БГИ-75У, БГИ-90У and their transshipment into container from the Transport packaging set ПКТІВ-120Н. 12

13 Mobile hot site 13

14 Mobile complex for unloading of the blocks SRS 14

15 Centralized disused SRS Storage The Storage is being built with the financial support of the Department of Energy and Climate Changes of the United Kingdom and European Commission Construction Start March 2011 End of construction December

16 General characteristics of Centralized Storage for DSRS Expected amount of DSRS is approximately spc. Main works on storage loading are oriented for the period up to 15 years with average production from 6 to 120 sources per day. Into the storage are placed: RAW in the form of DSRS in transport packaging sets (ПКТIВ- 120Н, ПКТ I В-180Н, ПКТ I В-230Н, ПКТ I В , ПКТ II В- 420 type or in other certified containers) DSRS in SRS blocks (type БГИ andэ) packages with alpha-sources in containers-collectors КС-004А radioisotope thermoelectric generator ( Betta-M type RTG)

17 Primary technologies According to transport-process scheme of the storage there are envisaged five flows : 1 Flow RTG 2 Flow blocks of sources BGR type 3 Flow neutron sources 4 Flow γ (Со-60, Cs-137 etc.), β(sr -90/Y-90 etc.), α+γ (Ra-226, Am-241)-sorces 5 Flow α -sources(pu-238, 239)

18 General schematic of sources movement in Centralized Storage for DSRS

19 Logistic plan of DSRS transportation from special combines to Centralized Storage for DSRS Information about presence of DSRS at special combines Availability of containers (packaging sets) at special combines, suitable for transportation into Centralized Storage for DSRS. Availability of purpose-build vehicle suitable for containers transportation into Centralized Storage for DSRS. Development of proposals concerning their transportation priority into Centralized Storage. Additional needs in purpose-build vehicles. Additional needs in containers, stands, other equipment which may be used in works related to preparation to transportation and direct transportation of DSRS into Centralized Storage for DSRS. Level of readiness of centralized Storage for acceptance of neutron sources from special 19 combines.

20 Automated system of management of radioactive waste transportation 20

21 Public campaign on collection of orphaned SRS from the population Puprose: to create a mechanisms of delivery by individuals and entities of radioactive materials without charging and without penalties to interest population in SRS delivery to special combines to raise awareness of potential SRS hazard on human health and environment to explain that illegal trade of radioactive materials would not bring substantial gains First stage: Introduction of amendments in the Criminal Code of Ukraine concerning voluntary delivery of radioactive materials Second stage: pilot campaign in one of region 21

22 RAW management of Military Programs Origin from the Soviet Period in Ukraine October2010 start of holding consultations and negotiations with the management of NATO Support Organization consideration of this issue at the meeting of the Working Group of the Ukraine-NATO Commission expert mission to the objects (storages) Trust Fund creation officially confirmed официально 2012 developed the draft Implementing Agreement Implementing Agreement has been signed 2014 internal procedures for ratification of the Implementing Agreement Signing ceremony of the Implementing Agreement between the Cabinet of Ministers of Ukraine and the NATO Support Organization (NSPO) for the Disposal of Radioactive Sources of Military Programs Origin from the Soviet Period in Ukraine 18 September

23 List of the proposed projects 1. Storage for long term storage of high level vitrified RAW from processing of spent nuclear fuel of reactorsvver-440 of Ukrainian NPP, coming from Russian Federation: storage construction; development and production of nonstandard equipment including loadtransfer device and penal for long-term storage of vitrifiedhigh level RAW 2. Disused sealed radioactive sources: Management of SRS, which are placed at well-type storages (inspection, development and production of equipment for retrieval, works on extraction); production of containers for neutron sources (type ПКТІІА-420Н or ПКТІІА-500Н) development and production of recharging containers, compliant with containers ПКТІІА-420Н or ПКТІІА-500Н (if supplier does not have the hot cell for transshipment of neutron SRS) 23

24 List of the proposed projects (continuation) production of stands for transshipment of neutron sources from one container into another. production of containers for γ-sources. production of technology containers for SRS sorting in hot cells of Centralized Storage. development of equipment and SRS retrieval from the inactive historical storages. RTG transportation from Odesa special combine to Centralized Storage. instrumentation of Ukrainian State Corporation Radon rapid response teams with technical means for radiological emergency response connected with loss of control over SRS (special technical means for accident localization, containers, radiation-measurement equipment, field instrumentarium for express analysis) 24
