  • 4. Korea Institute of Nuclear 4 New Legislation • In 2003, the Law for Physical Protection and Radiological Emergency (LPPRE) was promulgated, followed by the Enforcement Decree of the LPPRE and the MOST ordinances in 2004. • The MOST notices on the technical standards are under development. • Establishment of off-site emergency management centers near nuclear power plant sites is under way.
  • 5. Korea Institute of Nuclear 5 • Exemption: Radioactive materials whose total activities or activity concentrations do not exceed the exemption levels of the IAEA BSS are exempted from regulation. Consumer products specified by the Notice 2001-03 of the MOST are also exempted from regulation. • Notification: Radioactive material is contained in a well- shielded assembly; its activity is lower than 10 thousand times the exemption level; the dose rate does not exceed 10 µSv/hr. • License: Sealed sources having activity levels exceeding notification level; all unsealed radioactive sources except for those exempted. Activities of the Regulatory Authority
  • 6. Korea Institute of Nuclear 6 • Safety regulation on radioisotopes & radiation generators is carried out in the following forms: – Safety reviews and inspections on the usage and sales of radioisotopes for authorization and licensing – Licensing, safety reviews and safety inspections on large capacity accelerators – Safety reviews and inspections on the usage of nuclear fusion facilities – Design approval for radiation generating devices – Licensing reviews and inspections on the usage of nuclear materials. Activities of the Regulatory Authority
  • 7. Korea Institute of Nuclear 7 • Safety activities on the transportation of radioactive materials are carried out in the following forms: – Design approval of special form radioactive materials – Design approval of packages for radioactive materials – Manufacturing inspection and in-service inspection for packaging – Inspection on the safety of transportation of radioactive materials. Activities of the Regulatory Authority
  • 8. Korea Institute of Nuclear 8 • RASIS (Radiation Safety Information System) – Integrated network system of authorization and management of radiation sources – Trace radiation sources from manufacture or import to disposal, and manage the inventory – Databases shared with the MOST, KINS, other organizations such as Customs Service – Since the third quarter of 2003, the quarterly reporting of source inventory has been made through the online system. Activities of the Regulatory Authority
  • 9. Korea Institute of Nuclear 9 • Development of a real-time tracking system using the GPS and CDMA technology is under way to locate and recover industrial radiography sources when they are stolen or misplaced. A central monitoring system will be established in KINS. • To prepare for radiological emergencies involving lost or stolen radioactive sources, a facility will be constructed within the KINS site. The facility will be used to secure radioactive sources and to maintain emergency equipment that will be used by the emergency response team. Activities of the Regulatory Authority
  • 10. Korea Institute of Nuclear 10 Occupational Exposure Control • Since 2003, ICRP 60 recommendations have been fully implemented regarding the occupational dose limits and effective dose concepts incorporating internal dose • Medical hospitals are conducting sampling and measurement of airborne radioactivity (especially for I- 131) in the workplace to determine the need for internal dose assessment for the workers • Research is under way to set up technical standards for quality assurance of the internal dose assessment especially for WBC
  • 11. Korea Institute of Nuclear 11 Occupational Exposure Control • According to the Atomic Energy Act, nuclear licensees should have a personnel monitoring program for their radiation workers. • Personal dosimetry services for the assessment of external doses are provided by the accredited organizations. These organizations report monthly or quarterly occupational exposure of individual worker to the Korean Radioisotope Association (KRIA). KRIA maintains the records of occupational exposure of all radiation workers.
  • 12. Korea Institute of Nuclear 12 • Registration is required for any service that processes personal dosimeters used for monitoring of individual occupational radiation exposure. • KINS reviews and inspects the quality assurance program and consistency of quality for dosimetry service system and conducts performance test on the system on a yearly basis. • Research is under way to establish a reporting level for occupational exposures. Occupational Exposure Control
  • 13. Korea Institute of Nuclear 13 • KISOE (Korean Information System on Occupational Exposure) – internet-based network system – monitors and analyzes the trend of occupational exposures for the categorized radiation users – gives advice on the preventive action for the reduction of worker doses – ultimately aims to relate health effects with occupational exposures Occupational Exposure Control
  • 14. Korea Institute of Nuclear 14 Occupational Exposure in 2003 Category Collective dose (man-mSv) Average dose (mSv) No. of workers (person) Medical 2,574 0.97 2,654 Industry 4,197 0.93 4,513 NDT 9,161 2.80 3,272 Sale 6,068 0.82 704 Research 801 0.43 1,863 Education 1,384 0.33 4,195 Public 128 0.52 247 NPP 10,314 1.18 8,741 Total 29,069 1.11 26,189
  • 15. Korea Institute of Nuclear 15 • In 2003, the MOST set up a plan for the reduction of occupational exposures, especially in the nuclear power plant and industrial radiography areas. • For the industrial radiography area, the target for annual individual worker dose was set to 3.00 mSv in 2003, 2.50 mSv in 2005 (3.22 mSv in 2001). • For the nuclear power plant area, the target collective dose was set to 0.80 man-Sv/unit.year in 2004 (19 units O/H) 0.60 man-Sv/unit.year in 2005 (13 units O/H). • Through the periodic review of the performance of each sector, improvement in the management of occupational exposures will continue. Occupational Exposure Control
  • 16. Korea Institute of Nuclear 16 Medical Exposure Control • MOST : radiation therapy and nuclear medicine • KFDA : diagnostic radiation generators; dose QA program for quality assessment network • MOST notices “Standards regarding radiation safety management in medical areas” specifies: – Quality assurance program for prescribed dose delivery control – Safety requirements and calibration of irradiation equipment for radiotherapy referring IAEA TRS No.277 or equivalent – Qualification of Medical Physicist
  • 17. Korea Institute of Nuclear 17 Public Exposure Control • Environmental radiation monitoring: Currently a central and twelve local environmental radiation monitoring stations are operated along with unmanned posts at 25 locations nationwide. • KINS participates in the inter-comparison tests of the samples between some foreign laboratories such as EML, JCAC, RMTC to assure the quality of the measurement results of environmental samples.
  • 18. Korea Institute of Nuclear 18 • Safe management of radioactive waste and spent nuclear fuels: – The on-site storage is expected to reach the maximum capacity in about the year of 2008 for radioactive waste and 2016 for spent nuclear fuel. – The construction of waste disposal facilities is an urgent task that should be resolved in near future Public Exposure Control
  • 19. Korea Institute of Nuclear 19 • The government of the Republic of Korea, as a contracting party to the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management submitted to the IAEA its first national report for the implementation of the joint convention. • Korean delegations participated in the first review meeting held in the Headquarters of IAEA, Vienna, 3-11 November 2003.
