해외원전의 기능적중요도결정 프로세스 적용 추세

이상대,염동운 한국에너지학회 2021 한국에너지공학회 학술발표회 Vol.2021 No.4

원전 기능적 중요도결정(FID) 프로세스는 발전소를 구성하는 모든 설비를 대상으로 안전성, 신뢰성 및 운전가능성을 기준으로 설비의 기능적 중요도를 분류하는 것이다. 중요도 분류는 구조물이나 설비 고장으로 인해 중요한 기능이 무효화되거나, 성능이 저하되어 용인되지 않는 영향이 발생할 경우 해당 설비는 필수기기로 분류되어 관리하며 그렇지 않은 경우에는 비필수설비 혹은 고장허용설비(RTF)로 분류한다. 최근 해외 발전사들은 효율적인 방식으로 높은 수준의 발전소 안전성과 신뢰도를 유지할 수 있도록 중요도 분류 기준을 변경하는 활동을 추진하고 있다. 미국 원자력발전협회(INPO)는 설비성능지원 방문 그리고 미국 및 타국가 발전사 벤치마킹에서 얻은 경험을 반영하여 필수기기 정의를 다음과 같이 변경하였다. ·원자로 비상정지(scram) 또는 트립(발전정지유발기기) ·20% 이상의 심각한 출력 과도상태(출력 상실 사건) ·완화계통성능지표(MSPI : mitigating system performance index) 감시 기기 고장 ·다음과 같은 필수 안전기능의 어떤 것이라도 완전히 상실되도록 할 수 있는 단일 고장 —노심, 원자로냉각재계통(RCS) 또는 사용 후 핵연료저장조(SFP) 잔열 제거 — 격납건물 격리, 온도 또는 압력 — 반응도 제어, 필수 교류 전원 정비규정(Maintenance Rule)의 고안전중요도(HSS : high safety significant) 기능 또는 고위험도(RS : risk significant) 기능 상실을 초래할 수 있는 단일 설비 고장 해외 발전소들은 설비 안전성 뿐만 아니라 경제성을 고려하여 지속적으로 설비 신뢰성을 향상 시키는 활동을 수행 중이며, 이러한 활동의 일환으로 설비 중요도결정을 변경시키고 있다.국내 원전도 이러한 해외 발전소의 설비관리 추세를 적극적으로 검토 및 반영해야 할 필요가 있을 것으로 사료된다.

Forms of participation that are currently prescribed in the National Land Use and Planning Act and its subordinate legislation are largely public hearing, council hearing, opening plan document, newspaper announcements, and website announcements. The metropolitan area plan needs to go through public hearings and regional council hearings. And local government’s urban basic plan and urban management plan should go through the procedures circulated with public hearing, council hearing, opening plan document, and listening to local opinion. The actual practice of citizen engagement approach based on the rule of law is lacking and very formal. Of course 31 cities and counties of the Gyeonggi Province have citizen participation progresses on the legal system in the process of making and implementing urban plans. But they do not have plenty of new ways of citizen participation. So, citizen consulting group meetings are held in 28 cities and counties (90.3% of total), citizen talks are made in 24 cities and counties (77.4% of total), and citizen participation forums are held in 3 cities and counties (9.7% of total). So, citizen participation in the current system and practices strikes steps of information provision and consultation stage in the five phase of citizen participation. In order to practice citizen participation in urban planning practices, we propose the following measures instituted. First, local government need to create a citizen participation plan from the outset of plan-making. Second, operate the citizen participation forums from planning an early stage. Third, actively take advantage of the SNS and mobile environments in order to enhance openness and transparency. Fourth, submit citizen participation report on the process of plan draft review by upper government. Fifth, link a expert committee and dispatch experts in an advisory role to the citizen forums. Futhermore, the Gyeonggi Province should also promote provincial ordinance improvements for the citizen participation. In the short term, the province needs to amend the urban basic plan guideline draft to insert the rules of citizen participation practices. In the mid-to long-term, the province needs the Ordinance for the Citizen Participation-oriented Urban Planning to establish a regulatory mandates and incentives.

Currently, one of the most important problems of Korea is the low fertility - ageing society. The aggregate birthrate of Korea does not surpass 2.0 per woman and the rate of old person(over 65 years old) had marked 7% already in Korea and Gyeonggi Province. In this situation, this study aims to research the urban policy change response to the low fertility-ageing society and to know how to do. The direction of urban policy change response to the low fertility -ageing society is not to build the houses and facilities for accommodating pregnant woman and old person but to make pregnant woman and aged person-friendly urban space with well combined housing, transportation, cultural and welfare facilities. This policy is a kind of adaptation policy response to the phenomenon of the low fertility -ageing society. So, we have to do more challengeable policy approach to introduce young person and well educated and skilled foreigners into city centre. In getting urban policy change, the most important thing is breaking the policies of suburban newtown development, supply-oriented housing development and mobility-based transportation investment. To do so, we have to decrease index of city population and housing provision, to change from suburban newtown development to inner city regeneration, to focus on walkability transportation facilities, to implement barrier-free and universal design concept, and to introduce younger city programs. In addition, to implement the urban policy change response to the low fertility-ageing society, I would like to suggest 4 strategies and 12 policy tools. The 12 policy suggestions are i) investigation on barriers of city and countryside for pregnant woman and aged person ii) building complex town of residential-child care-educational facility iii) designation of aged person-friendly district iv) restructuring and collecting countryside villages v) rebuilding residential service facilities for old person vi) integrated residential and public health service system vii) leisure and cultural infra for aged person viii) supply of 3 generation lifelong house ix) providing retirer"s house x) law making of community development act response to the low fertility-ageing society xi) Gyeonggi Provincial urban planning ordinance response to the low fertility-ageing society, and integrated provincial government department for implementing policies of low fertility-ageing society.

Korea has severe disparities and social problems between regions, communities. Futhermore, Korea has a weak sense of community and social conflicts within and between communities. Until now, regional development policy has been established on the basis of the balanced development concept and mainly infrastructure construction and industrial park designation. From now, new approaches based on community welfare, health and health care, and social conflict management are needed in making regional development policy frame. Recently, international organization’s and Europe and Korea’s experimental regional growth strategy is focused on the efficiency - social equity - local autonomy in common. OECD is to promote the complementarity between different policy areas, that is, the mix of efficiency-equity-sustainability principles. Spatial practices that include the social cohesion objectives in the policy of regional development policy appear in examples of policies of EU, UK and France. EU operates inclusive growth, UK acts comprehensive budget subsidy (that is, a single pot budget), and France seeks to combine social cohesion policy and urban policy. Promoting effects and side effects of social cohesion-oriented regional development policy may appear. In the positive effects, firstly, it could achieve efficiency, equity, and environmental sustainability in regional development. Secondly, officials and residents can apprehend overall results of project and program budget and easily monitor the projects. But, side effects appear. The priority of individual program and project become ambiguous. And responsibilities between competent ministries and departments of municipality can be unclear. We propose three policy improvement suggestions. First, regional development policy should extend to social cohesion objectives. Second, to the vulnerable areas, integrated regional policy system should be made in regional government. Third, as a integrated regional restructuring subsidies in case of Gyeonggi Province, the Integrated Community Development Grant of Gyeonggi Province should be introduced.
