3Statistics for the period 1998 - 2003
4Origin of SIR in scrap in Bulgaria
1. Events inside the country (theft)
2. Import of contaminated scrap metal
3. Illicit traffic
5Existing and planned national regulatory
mechanisms
- Existing mechanism - legislation
- Act on the Safe Use of Nuclear Energy (ASUNE) -
June 2002 (new) - Basic Standards for Radiation Protection
(BSRP-2000) - January 2001 (new Regulation, based
on the IBSS No. 115 of IAEA, 1996) - Regulation No.0-35 on the safe use of sources of
ionizing radiation (1974) - Regulation No.5 on the issue of licenses for the
use of atomic energy (1989) - Regulation No.46 for safe transport of
radioactive materials (1976) - Regulation No.7 for safety management of RAW
(November 1991) - Regulation on emergency planning and response
(April 1998)
6Existing mechanism - Authorisation process
(licenses and permits for safe use of SIR)
Existing and planned national regulatory
mechanisms (cont.)
- The authorisation process is basic mechanism for
effective - control over possession and use of radiation
sources, which - includes granting of licenses
- granting of permits.
- According the new ASUNE there are six types of
licenses - use of sources of ionising radiation (SIR)
- manufacturing of radiation sources or of parts
thereof - handling of radiation sources for services
- import/export of radiation sources
- specialised training of persons engaged in
practices with SIR - transport of SIR
7Existing and planned national regulatory
mechanisms (cont.)
Existing mechanism - Authorisation process
(licenses and permits for safe use of SIR)
- According the new ASUNE there are six types of
permits - setting of a facility with radiation sources on
specific site - construction of a facility with SIR, assembly and
preliminary tests - decommissioning of a facility with SIR
- temporary storage of radiation sources
- single transport of SIR
- import and export of SIR or of parts thereof
8Existing and planned national regulatory
mechanisms (cont.)
- Article 35 of SUNEA
- license for operation of a nuclear facility is
being granted to a legal entity, registered in
the Republic of Bulgaria, which has approved
emergency plans for action in case of an
accident. Concerning the facilities with SIR
which provides the requisite measures for
radiation protection ensuring for all categories
exposured individuals, as in normal
circumstances, as well as in case of incidents
and accidents - Article 117 of SUNEA
- ... Emergency planning measures are being
established by the emergency plans as follows - - off-site emergency plan
- - on-site emergency plan
9Existing and planned national regulatory
mechanisms (cont.)
- inspections - to determine on-site whether
practices are carried out and sources are used in
accordance with the requirements of relevant
regulations and with any license or permits
conditions - radiation safety appraisals
- accident notification and investigation
- periodic feedback from users about key safety
parameters. - The priority and frequency of inspections
depend on the risk and complexity associated with
the practice, as well as potential accident
consequences and the type and frequency of
violations found during inspections.
10Types of practices and sources covered by the
legislation and requires emergency planning
- measures for emergency planning and emergency
preparedness are established by the state bodies
and licensees implementing activities related to - design of nuclear facilities
- construction of nuclear facilities
- commissioning of nuclear facilities
- operation and decommissioning of nuclear
facilities - manufacture, transportation and storage of
nuclear material - practices with sources of ionising radiation.
11Types of practices and sources covered by the
legislation and requires emergency planning
(cont.)
- nuclear and radiation accidents and incidents,
affecting potentially or really on the territory
of the Republic of Bulgaria or abroad, have
occurred - in nuclear facilities
- in facilities, operated with SIR (industrial,
agriculture, medical, research, etc) - in falling of satellite with nuclear reactor or
nuclear and radioactive substances on board - in use of nuclear weapons, nuclear and
radioactive materials for terrorist purposes,
sabotages and illegal traffic (SIR of an unknown
or untraceable origin) - in transportation of nuclear materials and SIR
- in radioactive wastes management, etc.
- the scrap metal processing facilities
12Existing emergency plans
- Off-site emergency plans
- - National Basic Plan
- (National Emergency Plan) for conducting
- of rescue and urgent post accident restoration
- works in case of disasters, accidents and
- catastrophes (last version April 2002)
- - in accordance to the National Emergency Plan,
emergency plans of the municipal administration
bodies and of the local self- government, of the
ministries and the organisations (last version
2002 2003) were developed.
Actions in case of an
radioactive cont. scrap
13Existing emergency plans (cont.)
- On-site emergency plans
- The NPP Kozloduy Emergency Plan, version 3, 2000
- The Plan for eliminating of the consequences and
for protection of the population and of the
environment in case of radiation accident during
transportation of spent/fresh nuclear fuel,
2001/April 2002 - Emergency Plan on RAW Department at NPP Kozloduy
, (July 2001) - The Emergency plan for the Nuclear Scientific
Experimental Base (NSEB) Bulgarian Academy of
Sciences, December, 2001 - The Emergency Plan of Permanent Repository of
Radioactive Wastes Novi Han, January, 2003 - The Emergency plans of all facilities (over 1500
in number), using SIR and generating RAW (last
versions in the period 1998 2003) - The Emergency Plans of the scrap metal processing
facilities
14Monitoring of the movement of radioactive
materials - scrap metal
Kremikovtsy facility
Stomana-Industry - Perniik facility
Automatic radiation monitoring
Manual dose-rate control (continuos)
15Governmental and private sector response
procedures and requirements
- In case of accident with SIR an inter
organisational team is being formed by the
Permanent Commission, which includes experts
from - Members of the emergency response team
- NRA
- Civil Protection State Agency
- National Centre on Radiobiology and Radiation
- Protection Ministry of Health
- Ministry of Internal Affairs Service "Control
of the Dangerous Substances" - Ministry of Environment and Waters (in case of

- 1. Detection of increasing of ?-background
- 2. Removing the wagon in a special place
- 3. Notification of the NRA, CPSA, MH, MI
- 4. Police investigation (for the origin of the
source) - 4. Determination the location of the SIR by
measurements - 5. Dose-rate control (continuously)
- 6. Individual dose control (continuously)
- 7. Request assistance (if necessary)
- 8. Guttering the national emergency response team
- (if necessary)
18Dispositioning (removal) of detected radioactive
materials (cont.)
9. In situ gamma-spectrometry for isotope
determination 10. Off-loading of the wagon
(partially or complete) 11. Localisation of the
source 12. Removing of the source 13. Temporary
storage 14. Monitoring 15. Exemption of the
clear scrap 16. Informing the population 17.
Informing the IAEA 18. Transpiration of the
founded SIR for special investigation (source
number, activity, etc.) 19. Transpiration of the
founded SIR to the permanent RAW repository
19Conducting drills and exercises
- Full scope emergency drills are organized each 5
years, for gaining knowledge about the national
emergency plan. - Exercises on adoption of plan elements are
annually performed - for 6 years 15 exercises, for example
- Bulgarian-Turkish exercises Combating of
- illicit trafficking of nuclear materials,
October 2002
20- Planned activities and mechanism
- Further development of the existing secondary
legislation by - developing a new categorization of the site used
sources of ionizing radiation (SIR) - developing a new threat categorization of
facility emergencies - including the scrap metal
processing facilities (category V) - Developing a new secondary legislation
- More clear lines of authority and responsibility
- Contractual requirement for submission of
certificate for radioactivity content in scrap
metal
21Planned activities and mechanism
- Strengthening the capabilities at all levels -
regulator, competent authorities (MH, CPSA, MI,
etc) and operator - Improvement of the Quality Management System
- Intensification of the use of external
expertise's. - Enhancement of the individual qualification of
the staff - Conducting drills and exercises
- Motivation of the staff.
