IAEA 안전기준 및 방사선원 위험도정보에 근거한 차등 인허가(면제·신고·등록·허가) 모델을 수립하고 정기보고, 검사, 심사 및 선량제약치 도입과 같은 인허가 범주에 따른 차등화된 규제요건을 도출하였다. 또한 현행 원자력안전법 관계법령에서 단일 허가로 인허가 관리되고 있는 대형 방사선시설의 안전성 확인절차를 개선하기 위하여 다단계 인허가체계 도입(안)을 도출하였다. 또한 안전성능에 기반한 규제 선도국의 규제검사체계 분석을 수행하고, 상기에서 제시한 차등 인허가 제도에 적합하고 한정된 규제자원의 효율적 운영을 도모하기 위한 규제검사제도 개선(안)을 도출하였다. 또한 위험도 범주에 따라 저용량 방사선원(신고대상)인 가스크로마토그래피 중 전자포획형과 고위험 방사선원(허가대상)인 방사선투과검사용 방사선원에 대한 방사선리크스 평가모델을 분석하였다.

소유ㆍ관리 책임이 명확하지 않은 미규제 방사선원(부지오염 등의 기존피폭상황 포함)에 대한 국가안전관리 표준모델을 수립하였다. 또한 우리국민의 생활패턴에 기반한 선량평가인자를 활용하여 방사선리크스 평가모델을 마련하고 이를 이용하여 선량평가 코드를 개발하였다.

국제안전기준과 국내외 적용사례 검토를 통해 도출한 방사선분야 운영·규제경험 및 교훈반영을 위한 개념설계 모델을 시범사업형태로 적용하여 그 효과성을 검증하였으며, 방사선원 및 방사선이용시설의 안전성능 모니터링을 위한 성능지표체계를 도출하였다.

또한 사용자 규제와 연계성을 강화함으로써 차등적 인허가체계 규제효과성을 제고하기 위한 방사선기기설계승인 제도개선(안)을 도출하였다.

Ⅳ. Research Results

1. Development of authorization and inspection technologies for the lifecycle of utilization of radiation, based on risk-informed and performancebased approach

In this study, a comprehensive draft action plan to improve the authorization system and regulatory inspection program based on the conceptual model for graded authorization(exemption, notification, registration and license), which is to be applicable in Korea, was proposed. In the proposed model, the following provisions were included:

- Introduction of the concept of registration into the authorization system and development of graded regulatory requirements in regard to assessment, inspection and dose constraint, etc.

- Introduction of multistage authorization for complex and large scale radiation facilities and development of relevant regulatory requirements such as periodic safety review and pre-operational inspection, etc.

2. Development of an optimized safety management technology for unregulated radiation sources

The implementation procedure for national response and management of unregulated sources or existing situations originated from past activities which are not under regulation was developed. It includes improvement plan for management of radioactive materials of which responsibilities of possession and management are not clear, which is anticipated to be the root cause of the radioactive contamination of a road in Seoul 2011 and financial arrangement for disposal.

In addition, standard model for risk assessment with factors suitable for domestic characteristics which is to be applicable for restoration of contaminated site was developed. Based on this model, dose assessment code was developed by use of C++ programming language.

3. Development of the Verification Technology for Radiological Risk

A standard model was established in order to assess the radiological dose from handling, storage etc. two types of radiation source being used for electron capture detectors for gas chromatographs and industrial radiography, which are subject to notification and license within the graded authorization system

4. Development of a systematization technology for feedback of regulatory experiences and lessons-learned in radiation safety

In this study, a pilot project of a conceptual model operating and regulatory experience and lessons-learned system was implemented to verify its effectiveness. The database for all information collected from implementation of a pilot project(internal and external operating and regulatory experience and lessons-learned derived from its analysis) was developed by use of a spreadsheet software.

In addition, international standards and technical information on safety performance indicator of selected leading countries were investigated and analyzed. Based upon this analysis, safety performance indicators were selected which is to be applicable in radiation sources and facilities in Korea.

5. Development of comprehensive technical standards for radiation devices

In this section, the effectiveness of regulatory framework for design approval of radiation devices in Korea and technical status which should be improved were was analysed. Based upon those results, a draft improvement plan, which are newly proposed classification of radiation devices, which is attributed to required level for user authorization system, reinforcement the interfaces between design approval of radiation devices and regulatory activities of authorized users and strengthening of regulation on implementation of quality assurance program of radiation devices, was derived.
