Session I: Country Report Presentation
- Updates on Radiation Safety and Radioactive Waste Management/Revision of Consolidated Report on Radiation Safety drafted in 2010 -
All countries in this session have based their radiation protection systems on the IAEA guidelines. As such, much of the material is similar, with small variations. The contents of most of the presentations were likewise similar following this format:
  1. Radiation Safety in Radiation Industry Facilities
     1.1. Legislative Framework, Policy and Structure
     1.2. Radiation Facilities and Radiation sources
     1.3. Education and Training
  2. Status of Radiation Safety Management
     2.1. Radiation Workers
     2.2. Public
     2.3. Radioactive Waste Management Update

1) Australia
Mr. L Dimitrovski began by explaining Australia's fragmented legal framework and the political reality of the environmental parties having a big influence on the development of policy. He spoke of the challenges facing in Australia: how to recycle heavy water for the reactor; expanding Mo-99 production with the decline in world production; building a new synroc plant for waste treatment; and the return of reprocessed spent fuel as Intermediate Level Waste. There is a national education and training scheme for radiation protection, which is being expanded regionally as part of the Regional Security of Radioactive Sources project. ANSTO's emergency preparedness is good, and there have been two recent emergency exercises involving the local officials.

2) Bangladesh
Dr. Islam spoke of the structure of the Bangladesh Atomic Energy Commission (BAEC) and how it is both the regulator and the operator. He detailed the activities of the Health Physics and Radioactive Waste Management group, including all the regional and international projects that Bangladesh is involved in. The national radioactive waste policy is being updated and reviewed currently, as Bangladesh would like to have a nuclear power plant (NPP) program. Bangladesh plans to have two 1000 MWe nuclear power plants by 2021. The radioactive waste from these facilities will be treated on site and then transferred to the BAEC and its centralised waste facility until a disposal site is opened. Physical security has been upgraded at all radioactive facilities as part of an international project. There is a national emergency plan which is overseen by the regulator.

3) China
Mr. Zhang spoke of how China has developed a new plan after the Fukushima Daiichi incident. There were four parts:
1. Check the emergency plans and nuclear safety of all radiation facilities;
2. Assess all nuclear power plants under construction for emergency preparedness and nuclear safety;
3. Assess all nuclear facilities for emergency preparedness and nuclear safety;
4. A suspension of new approvals for nuclear power plants until a new plan for radiation safety has been developed.
All tasks are nearly completed.

4) Indonesia
Dr. Syahrir focused on radiation safety, explaining the legal framework and the structure of the regulator. The licensee is responsible for emergency planning, education and training of radiation workers. Future problems in Indonesia are: Orphan sources and scrap metal; Clearance level application; Reuse and recycling of sealed sources; Decommissioning a reactor; and siting a waste disposal facility. A preliminary safety analysis report (PSAR) has been developed for siting a nuclear power plant with a view to having a nuclear power program in Indonesia. There have been improvements in emergency preparedness following from exercises, training and documentation reviews within a technical co-operation project with ANSTO (Australia).

5) Japan
Mr. Yasushi NAKAMURA reviewed the present state of radiation control in nuclear power plants in Japan. He discussed the system of rules for radioactive waste management and radiation work management. He emphasized the technical specifications of NPP, which specify measures for ensuring safety have to be made prior to operation, and approval shall be obtained from Government. The technical specifications also cover radioactive waste management and radiation management (control). He described the treatment of radioactive gas, liquid and solid wastes from NPP. As electric power companies have discharge control guides 50μSv per year, all plants under normal operation released less than 1% (one hundredth) of the guideline. However, the increasing generation of solid radioactive waste is important problem for us. Environmental monitoring is being carried out in areas surrounding power plants by working with local governments.
Mr. Yasushi NAKAMURA discussed radiation work management in a NPP. Radiation workers must go through these procedures to work inside a control area. For the last decade, EPD replaced film badges and TLD. In Japan, whole-body counters are used before starting work at the nuclear facilities, when leaving the nuclear facilities, and periodically while working. After 1990, more than 90% of workers received dose below 5mSv/y. In the radiation management system, a radiation control work permit is needed for start working. A NPP is divided into 3 areas. The controlled areas are classified according to the extent of radiation or contamination.

6) Kazakhstan
Mr. Yuri Aleinikov presented the status of Radiation Safety and Radioactive Waste Management in Kazakhstan. He described the legislative framework and regulatory body in Kazakhstan. The regulatory authority is the Committee of Atomic Energy, Ministry of Industry and New Technologies. He gave the details of R&D on Nuclear Reactor, such as experiment on core melting in Na-coolant for fast reactor, etc. There is the decommissioning project of a nuclear reactor which shut down in 1997. The storage facility of DSRS and solid waste is in place, under the Ministry of Science. He also described on the radioactive waste long term storage, RW casks, the feasibility study on the project radiation protection chamber and long term storage of solid waste and spent fuel treatment.

7) Malaysia
Mr. Nik Marzukee provided and overview on Use of Radiation Sources and Status of Radiation Safety Management. He explained nuclear regulatory system related in Malaysia. Although the major part of the responsibility is under the AELB, the control of radioactive applications in medical purposes is under the jurisdiction of the Director General of Health, Ministry of Health. The records of specialists and workers are under both the AELB and MoH. He added there are approximately 7 providers and 100 radiation safety training courses covering subjects in radiological protection. SSDL-Nuclear Malaysia provides standardisation and calibration. The lab is member of the IAEA/WHO Network of SSDLs.
Mr. Nik Marzukee listed the orders, license conditions, codes of practice, guidelines established under Act 304 and by regulatory directive from the AELB.
He detailed the radioactive waste inventory in Malaysia.

He continued with regard to radiological Protection for workers / Area / Public / Emergency.

8) Mongolia
Ms. N. Oyuntulkhuur gave an overview of RS and RWM in Mongolia. She described the application of nuclear technology in Mongolia, but there is no nuclear power plant in Mongolia. The legislative framework, regulatory body and its functions was given in details. The Nuclear Energy Law was established in 2009. There are 1213 radiation workers, in 163 organizations which deal with radioactivity. The Nuclear Energy Agency (NEA) is the regulatory body. There are several controls regarding to radiological protection from public, such as control of discharge of radioactive waste, control of food stuffs, consumer products, radon, uranium exploration, NORM, materials for recycling, etc.

9) Thailand
Ms. Nanthavan YA-ANANT updated Report on Radiation Safety and Radioactive Waste Management in Thailand. In the first part, she described legislative framework and regulatory (Office of Atoms for Peace - OAP) and operator (TINT) organizations. She updated the amount of radioactive material and atomic energy users (OAP,2010) and the courses and curriculum related to radiation safety.
The second part is Status of Radiation Safety Management. She started with Radiation Safety Management in radioisotope Usage, Research Reactor and Radioactive Waste Management, which should follow the licensing system, standards and guidance. The OAP operates and maintains a SSDL for national standard radiation dosimetry and calibration of radiation protection instruments. The Department of Medical Science of Ministry of Health operates a SSDL for radiation dosimetry as National Standard for film-badges and TLD badges. Thailand has two International Monitoring System Stations under the CTBTO and other gamma (dose rate and accumulation) radiation monitoring. She explained the National Nuclear and Radiological Emergency Preparedness and Response Plan which covers drills and exercises for radiological and nuclear emergency. On radioactive waste management, she stressed there is only one radioactive waste management center in Thailand which covers collection, transportation, segregation, treatment, conditioning, and storage. She updated the inventory of existing radioactive wastes at TINT (as May 2010).

10) Vietnam
Mr. Nguyen Ba Tien provided an update on radiation safety and radioactive waste management in Vietnam. The first NPP will be put in operation in 2020 with capacity of 2000 MW and the second NPP with capacity of 2000 MW will be put in operation in 2021. The Atomic Energy Law comes to enforce on 1st January 2009. In 2008, there are more than 5,300 radiation workers belong to radiation installation and related organizations. Currently the Service monitors approximately 6,000 workers. There are 358 radiation facilities with a 500 kW reactor and a 30 MeV cyclotron. The RWM facilities are in Dalat, for treatment and disposal, and in Hanoi, an interim storage facility. INST in Hanoi operates and maintains a SSDL for national standard radiation dosimetry and calibration of radiation protection instruments. INST follows intercomparison and international supports in SSDL.
In the Status of Radiation Safety Management, Mr. Nguyen Ba Tien listed Vietnam standards on radiation safety. Regarding site selection for Low Level Radwaste Central Facility, only the coastal region of south-central Vietnam might be considered as relevant and the most suitable region for a national near surface disposal facility of low and intermediate levels radioactive wastes.
