2015년 7월 이란과 서방국가와의 잠재적인 핵협상이 극적으로 체결됨에 따라 오랜 기간 동안 문제되었던 이란의 핵 문제가 서서히 해결되고 있다. 이란의 핵협상 과정을 눈여겨 봐야 하는 이유는 한반도 역시 북한의 핵문제로 인해 큰 위협을 받고 있기 때문이다. 북한과 이란의 핵문제를 비교할 경우 양 국의 정치체계와 구조, 핵협상 과정에서 큰 차이가 있기 때문에 북한의 핵문제를 해결하기 위한 정책적 시사점을 찾기가 사실상 어렵다. 일부에서는 이란의 핵문제와 북한의 핵문제와는 상당한 차이가 있기 때문에 이란의 핵협상으로부터 북한의 핵문제 해결을 위한 시사점을 찾기 힘들 것이라는 부정적 견해를 내고 있고 또 다른 한편에서는 이란의 핵협상 결과가 분명 북한의 핵문제에 긍정적 영향을 미칠 수 있는 요인을 찾을 수 있을 것이라는 견해를 제시하고 있다. 이란과 북한의 핵문제가 상당한 차이가 있음에도 불구하고 이란의 핵 협상과정에서 북핵문제 해결을 위한 긍정적인 방안을 찾고자 하는 것은 그만큼 북한의 핵문제가 한반도 전체의 사활과 관련된 문제이기 때문이다. 본 연구에서는 이란의 핵협상 타결과정과 성공요인을 분석하는 데 초점을 맞추고, 분석된 요인으로부터 북한의 핵문제 해결을 위한 시사점을 알아보고자 한다.

As North Korea signed 'the Korea Peninsula Non-Nuclearization Joint Declaration' at the end of last year as well as full-scope safeguards agreement with the IAEA in Jan.30 1992, her nuclear activity was incorporated into the international monitoring system and opportunities were arranged to .obstruct her nuclear weapon development and nuclear material diversion, which have been international issues up to recent years. However, achieving goals of the Joint Declaration and safeguards agreement should presuppose North Korea's sincerity toward the abandonment of nuclear weapon development. In this study, first of all, her nuclear policy, current situation of nuclear development and the capability of nuclear development are analyzed. Also, based on the analysis. attempts have been made to find methods of effective performance of the South-North Korea mutual nuclear inspection and the suggested methods are as follows; 1) Analysis of the limits of IAEA inspection and suggestion of its supplementary strategies 2) Securing and training professional inspectors for the South-North mutual inspection 3) Establishment of the verification technology to detect nuclear material diversion.

Characterization of special nuclear material may be performed using energy spectroscopy of either the neutron or gamma-ray emissions from the sample. Gamma-ray spectroscopy can be performed relatively easily using high-resolution semiconductors such as high-purity germanium. Neutron spectroscopy, by contrast, is a complex inverse problem. Here, results are presented for $^{252}Cf$ and PuBe energy spectra unfolded using a single EJ309 organic scintillator; excellent agreement is observed with the reference spectra. Neutron energy spectroscopy is also possible using a two-plane detector array, whereby time-of-flight kinematics can be used. With this system, energy spectra can also be obtained as a function of position. Spatial-dependent energy spectra are presented for neutron and gamma-ray sources that are in excellent agreement with expectations.

China, Japan and Korea are the world's top 10 energy consumers, and so very interested in the development of seabed hydrocarbon resources in order to meet their energy demands. The East China Sea is the tri-junction area where three countries' entitlements on the maritime boundaries are overlapped. There are abundant oil reserves in the East China Sea, and therefore competitions among countries are growing to get control of them. Although these countries have concluded the bilateral agreements to jointly develop resources in the East China Sea, they do not function as well. Because joint development and management of seabed petroleum resources can lead to stable development system, and to lower possibility of legal and political disputes, the needs for joint development agreement among three countries are urgent. Meanwhile, Northeast Asian seas are semi-closed seas, which are geographically closed and vulnerable to marine pollution. Moreover there are a lot of nuclear power plants in coastal area, and seabed petroleum resources are being developed. So it is likely to occur nuclear and oil spill accidents. Fukushima nuclear disaster and Bohai Bay oil spill accident in 2011 are the cases to exhibit the potential of major marine pollution accidents in this area. It is anticipated that the risks become higher because power plants and offshore oil platforms are extending gradually. Therefore, the ways to seek the joint marine environmental protection agreement focused on regulation of nuclear power plant and offshore oil platform have to be considered. In this paper, we try to find the way to make joint development and joint environmental protection agreement in Northeast Asian seas. We concentrate on the measure to drive joint development of seabed petroleum deposits in East China Sea's overlap area, despite of maritime delimitation and territorial disputes, and we try to drive joint marine environmental protection system to respond to marine pollution and accidents due to offshore oil platform and nuclear power plants. Through these consideration, we seek solutions to deal with lack of energy, disputes of maritime territorial and boundary delimitation, and marine pollution in Northeast Asia.

The cladding temperatures and axial mass distribution computed by MAAP5 were compared with their measured values in the test bundle of the Phebus Test FPT0. The computed cladding temperatures were in good agreed with the measured values in the pre-transient phase. In the transient heat-up phase, the computed temperatures were overestimated by the Baker-Just correlation in MAAP5, but the computed temperatures could simulate the subsequently measured values. The computed mass distribution in the axial direction was in qualitative agreement with the measured one for post-test fuel damage observations. The calculated flow areas of inner and outer regions in the test bundle were compared with the photographic observations. MAAP5 computed them at the height of 0.2 m where the molten pool formed was in qualitative agreement with the photographic observations. It was found that the remaining steam flow paths might be caused by the gas-liquid two-phase flow counter-current flow limitation.

In PWR three-dimensional transient coupling calculation software CORCA-K, the nodal Green's function method and diagonal implicit Runge Kutta method are used to solve the spatiotemporal neutron dynamic diffusion equation, and the single-phase closed channel model and one-dimensional cylindrical heat conduction transient model are used to calculate the coolant temperature and fuel temperature. The LMW, NEACRP and PWR MOX/UO₂ benchmarks and FangJiaShan (FJS) nuclear power plant (NPP) transient control rod move cases are used to verify the CORCA-K. The effects of burnup, fuel effective temperature and ejection rate on the control rod ejection process of PWR are analyzed. The conclusions are as follows: (1) core relative power and fuel Doppler temperature are in good agreement with the results of benchmark and ADPRES, and the deviation between with the reference results is within 3.0% in LMW and NEACRP benchmarks; 2) the variation trend of FJS NPP core transient parameters is consistent with the results of SMART and ADPRES. And the core relative power is in better agreement with the SMART when weighting coefficient is 0.7. Compared with SMART, the maximum deviation is -5.08% in the rod ejection condition and while -5.09% in the control rod complex movement condition.

본 논문은 한국정부가 유치한 아태원자력협정(RCA)사무국의 국제기구화 추진 현황과 향후 과제를 중심으로 분석하였다. 주요 내용으로는 RCA사무국 유치와 지원활동, 국제법적 지위 확보와 관련된 주요 문제점에 대해서 기술하였다. 이와 함께 RCA 협정개정과 사무국의 국제기구화 추진에 대한 주요 쟁점 분석과 대응 방향을 분석하였다. 한국은 개도국으로서 원자력의 이용개발을 성공적으로 수행한 모델로 평가받고 있으며 앞으로 원자력 기술 선진국으로서 역할을 보여주는 것이 필요하다. 여기에는 국제기구 유치가 적절한 수단이 될 수 있다. 한국정부가 유치에 성공한 RCA사무국의 국제법적 지위 확보는 협정개정이나 보조협정의 체결이 필수적이다. 이를 위해서는 2017년 협정개정과 이후 본부협정 체결을 목표로 범부처 차원의 RCA사무국 국제기구화기획단을 운영하는 것이 바람직이다. 이와 함께 사무국의 지원단도 구성하여 사무국의 사업 수행과 기술적 지원을 수행하는 것도 필요하다.
