미국 NRC는 현재 가동중이거나 신규건설될 원전플랜트에 적용할 중대사고예방 및 축소에 관한 세부적인 정책안을 마련하여 시행중이다. 이를 위해서는 중대사고의 성격과 결과에 대한 철저한 연구에 의해 뒤받침 되는 규제 가이드라인의 제정이 필요하다.

Energy demand forecast which serves as an essential input in energy policy is exposed to multiple factors of uncertainty such as GDP and weather forecast uncertainty. The Master Plan of Electricity Market in Korea which is biennially prepared is critically based on fluctuating energy demand forecast whereas its resulting proposal on electricity generation mix is substantially irreversible. The paper provides a real options model to evaluate energy transition policy by considering Knightian uncertainty as a measure to study multiple uncertainties with multiple set of probability distributions. Our finding is that the current energy transition policy under the master plan is not robust in terms of securing stable management of electricity demand and supply system.

존 켈리 회장은 7월 12일 경주시 힐튼호텔에서 열린 '원자력 안전 및 해체산업 육성 국제 포럼'에 참석하여 'Perspectives on the Future of Nuclear Power in the United States'를 주제로 특별강연을 했다. 켈리 회장은 강연을 통해 미 행정부의 원자력정책, 미국 원자력산업의 단기 도전 과제, 전력 생산에서의 이산화탄소 감축과 원전 역할, 원전의 지속적인 운영, 미국에서 진행되는 신형 원자로 설계 등을 피력했다. 켈리 회장은 이날 언론과의 인터뷰에서 "한국은 원자력산업 강국인데, 원전 안전성에 대한 과학적인 근거보다 정치적 이슈로 신규 원전을 짓지 않고 수명 연장 대신 조기 폐쇄를 결정한 것은 우려할 사안"이라고 말하고 "원전산업 축소는 장기적으로 기업의 전력 확보가 어려워져 경제적 타격을 입는다. 특히 한국은 원전을 수출하면서 탈원전정책을 펴면 수출에 지장을 받지 않을까 걱정된다."고 밝혔다. 켈리 회장은 MIT 원자력공학박사로 미국 에너지부(DOE) 원자력에너지 기술책임자를 지냈다. 본고는 발표 내용을 정리한 것이다.

In this paper, we empirically evaluate the potential performance of energy conversion policy and analyze its effects on power generation sector. We first examine the degree of substitutability between energy inputs by measuring the price elasticities of energy demands and then estimate the changes in CO₂ generation when the proportions of nuclear power plants and renewable power generation are increased. The shadow prices of nuclear power and renewable energy are calculated to compare the potential costs of power generation between the two energy sources. We analyze the impacts of the expansion of nuclear power plants and renewable power generation on power supply price. Nuclear and renewable energy were measured to be complementary to each other. The expansion of nuclear power plants has been more effective in reducing CO₂ emissions than increasing renewable power generation. In most years over 2002 to 2016, the impact of nuclear power expansion on the power supply price was generally higher than that of renewable power generation, with relatively large range of fluctuations.

우리나라의 현행 전원믹스는 경제성의 측면에서 상당히 왜곡된 것으로 언급되고 있으며, 전력시장의 기저발전기에 대한 규제상한 가격은 이를 간접적으로 입증하는 근거라 할 수 있다. 균등화 발전원가를 이용하여 장기한계비용을 도출하고, 이를 부하지속곡선에 대입하여 산출한 경제적 전원믹스은 원자력 발전용량의 대폭적인 증가의 필요성을 보여준다. 이는 원전이 기저전원으로 경제성을 가지는 측면이 있지만 무엇보다도 우리나라의 높은 부하율(편평한 부하지속곡선)에 기인하고 있다. 이산화탄소 배출비용의 부과는 원전의 경제적 우위를 확장시키는 반면 전원다변화를 현격하게 축소시키는 결과를 가져와 정책목표간 조율이 필요함을 시사한다. 균등화 발전원가는 전력시장체제의 가격 및 수익에 대한 리스크를 효과적으로 반영하지 못하므로 포트폴리오 이론 및 실물옵션 이론 등을 활용한 경제성 평가방법론의 개발이 향후 과제로 제기된다.

This paper analyzes the effects of nuclear power generation on industrial growth in using the data of 22 manufacturing sectors in 14 nuclear power countries. The hypothesis that the change in the proportion of nuclear power generation in total electricity generation affects industrial value-added and industrial output through industrial electricity price reduction was tested using the dynamic panel data model. First, it was estimated that the increase in nuclear power generation by a 1% leads to a 0.8% reduction in electricity price. The results indicate that when nuclear power generation increased by a 1% point, industrial value-added and output increased by 0.16% and 0.23%,respectively, in the short-run and by 0.51% and 0.85%, respectively, in the long-run. It was also inferred that the effect of nuclear generation on industrial competitiveness working through electricity price reduction rely on institutional settings in the electricity markets. That is, the competitive effect is greater in the countries such as U.K and Japan where electricity price is high and price volatility is large. Meanwhile, in Germany which has pursued phasing out nuclear power, industrial competitiveness is promoted through stable electricity supply.

Korea faces major changes in energy policy, which include eco-friendly and zero-nuclear power. On the other hand, there are very few policies for the waste-management of mid- to large-sized lithium-ion batteries, such as electric car batteries and energy storage systems, which are expected to increase explosively due to such energy policy changes. Therefore, this study estimated the amount of mid- to large-sized lithium ion batteries waste and performed economics analysis of a middle and large sized secondary battery recycling project. Based on the results, a policy alternative for the revitalization of the related lithium-ion battery recycling industry is suggested. As a result, the B / C ratio of a domestic mid - to large - sized lithium ion battery recycling project is 1.06, in which the benefit is higher than the cost, so the business is economic feasible. Although the recycling project's economic efficiency is high, the recycling industry has not been activated in Korea because the domestic demand for rechargeable batteries recycling is very low. To solve this problem, this study proposes a plan to activate the industry by adding lithium secondary batteries to the EPR (Extended Producer Responsibility) items.

This paper uses research on the Levelized Cost of Electricity (LCOE) in South Korea to conduct a simulation analysis on the impact of nuclear power dependency and usage rates on the social costs of power generation. We compare the $7^{th}$ basic plan for long-term electricity supply and demand, which was designed to increase nuclear power generation, to the $8^{th}$ basic plan for long-term electricity supply and demand that decreased nuclear power generation and increased renewable energy generation in order to estimate changes in social costs and electricity rates according to the power generation mix. Our environmental generation mix simulation results indicate that social costs may increase by 22% within 10 years while direct generation cost and electricity rates based on generation and other production costs may increase by as much as 22% and 18%, respectively. Thus we confirm that the power generation mix from the $8^{th}$ basic plan for long-term electricity supply and demand compared to the $7^{th}$ plan increases social costs of generation, which include environmental external costs.

The concept of a risk society, which was originally suggested by German sociologist Ulrich Beck, is insufficient to reveal how a certain risk materially and discursively unfolds on the ground and how its various dynamics are recognised by diverse actors because of the concept's spatial insensitivity. As an alternative approach, this paper introduces the concept of the riskscape, which was suggested by German geographer Detlef $M{\ddot{u}}ller$-Mahn, and analyses this concept in the context of the East Asian developmental state. It is meaningful that the East Asian developmental state thesis has strongly promoted the role of the state in stimulating national economic development in underdeveloped countries. However, it should also be noted that an active state role in encouraging modernisation and economic growth within a very short time produces consequences of what Beck calls 'manufactured risks', such as nuclear power plants. Therefore, it is essential to analyse the state in comprehending modernisation and the risk society in East Asia. More specifically, using the case of the location policy for nuclear power facilities, this article reveals how dominant social forces acting in and through the state constructed a national riskscape that minimises the gravity of local risks while prioritising the economic value of the national economy over local risks to produce rapid modernisation. Additionally, it is argued that a dominant national riskscape may become weak from competing with different riskscapes that are constructed based on contingency factors (e.g., political democratisation or a natural disaster). Based on these analyses, the article emphasises that interdisciplinary research using the concept of the riskscape is required to better explain the risks in East Asia.
