  • This paper introduces the 'Smart Scoping for Environmental Investigations Technical Guide' issued by the US Environmental Protection Agency in 2018, which describes the use of smart scoping during lifecycle of remedial investigation projects. This paper also briefly summarizes the guidelines of soil and groundwater contamination investigation of South Korea. The smart scoping practices can support the development of a robust and realistic conceptual site model that is very useful for investigations and evaluations of the contaminated site. The application of evaluation tools relevant for the site-specific characteristics is important for the development of a conceptual site model. The smart scoping recommends the use of previous investigation data and implementation of best proven strategies for successful remedial investigation project. The use of smart scoping in contaminated site investigation will provide better management of contaminated sites.

  • A scoping system is ultimately aimed at accomplishing the efficient Maritime Safety Audit by enhancing the MSA and thus now it's necessary to consider introducing the scoping system to MSA in more positive way. However, system design which will be optimized to MSA needs to be developed in such a way of analyzing the domestic environmental impact assessment system as well as comparing with the current operation of scoping system in foreign countries.

  • In this study, we individualize the clauses to sort out the troubled ones, draw up a interrelation model in order to visually organize the relations, and finally, suggest the desirable application idea. The interrelation model suggested in this study has been made based on the matrix method. On this matrix, we arranged the environmental factors on horizontal and vertical axis, and when we describe the relation of each factors, we set the horizontal axis as the base and divided the content into three grades : Fine, Medium, and Poor. In addition to that, we expressed those three grades into numerical value like 3 points for Level Fine, 2 points for Level Medium, and 1 point for Level Poor and then, we converted this numerical values into index numbers. We could classify the index numbers such as AS, PS, Q-index, P-index. AS is an index numerically shows the degree of giving environmental effect, PS is an index numerically shows the degree of receiving environmental effect, Q-index is an index shows the aggravate degree, and P-index shows the relation degree. The Q/P-index with large numbers has considerable effect on the environmental system, while the small numbered Q/P-index barely effect on the environmental system. Moreover, we classified the environmental factors into 5 levels(I~V) according to the relations between the Q-index and P-index. Level I is less affected by the environment and has more giving effect, while Level V is more sensitively affected by the environment and has more receiving effect, which we considered important. Therefore, we could come up with the result that if we consider the each level of factors when we evaluate the EIA, the result would be far more accurate and reliable since it contains mutual relation aspect of EIA. The suggested interrelation model in this thesis is presentable as one of those scoping system. We highly believe the need of scoping system in EIA and suggest the interrelation model as the alternative idea for scoping system.

  • This paper assessed environmental impacts of marine sand mining on coastal areas and Exclusive Economic Zones (EEZs) of Korea, and diagnosed problems of the related assessment statements for suggesting key assessment items (scoping) and system improvement. To mitigate conflicts and environmental impacts caused by large-scale, concentrated sand mining, we suggest it is critical to promote sustainable and eco-friendly utilization of marine resources while listening opinions from various stakeholders and analyzing alternative plans. Especially, it should be mandatory as a scoping item to provide verifiable data on the amount of sand, potential and accumulative impacts by mining, and key assessment items (e.g. erosion and sedimentation by submarine topography, benthic change, spreading of suspended solids, water pollution, grain-size change, and impact on fisheries resources). We also suggest that postassessment and monitoring should be improved to enable tracking of environmental impacts caused by sand mining through seasonal monitoring together with intermittent short-term surveys. In addition, effective measures to mitigate the impacts is also essential. As repeated sand mining at large-scale can damage marine ecosystems by long-term accumulated impacts, we suggest that assessment systems and regulatory policies should be developed and established, especially for ensuring reliability of assessment and review on selected major sandmining projects.

  • This paper concerns with developing a simplified in-core fuel management scoping tool for PWR. For this purpose the point reactivity model is put into a fuel cycling decision code, FCYPRM. Modified Borresen's coarse-mesh diffusion theory and nodal expansion method are utilized to form a spatial neutron analysis code, CMSNAP. Numerical experiments are per- formed to determine a set of empirical shuffling rules for working out an automated fuel loading pattern search code, ALPS. The numerical examples are presented for verifying effectiveness and applicability of individual codes. By structuring and applying three codes for reload core design problem of a PWR, it is demonstrated that these codes provide an effective in-core fuel management scoping tool for PWR.

  • The objective of this study is intended to propose plans for reforming environmental impact assessment(EIA) systems by reviewing the current legal systems of EIA related laws and their implementation status in Korea, and by comparing the Korean situation to EIA systems in several foreign countries. This study tried to integrate all EIA related systems scattered over several laws into one comprehensive EIA law, and also to develop legal procedures necessary to accomplish the legislative purpose of the integrated EIA law. Therefore, I propose four reforms (1) All EIA systems should be integrated into one comprehensive EIA act. (2) Administrative plans and policies, though environmentally harmful, which are not currently subject to any prior consultation system, should be covered by the prior consultation system. (3) A screening or scoping should be adopted. (4) Widen civil participation should be encouraged and the administrative control enforcement and introduction of group litigation or citizen suits would be considered.

  • Scoping analyses for the Safety Injection System (SIS) configuration for Korean Next Generation Reactor (KNGR) are peformed in this study. The KNGR SIS consists of four mechanically separated hydraulic trains. Each hydraulic train consisting of a High Pressure Safety Injection (HPSI) pump and a Safety Injection Tank (SIT) is connected to the Direct Vessel Injection (DVI) nozzle located above the elevation of cold leg and thus injects water into the upper portion of reactor vessel annulus. Also, the KNGR is going to adopt the advanced design feature of passive fluidic device which will be installed in the discharge line of SIT to allow more effective use of borated water during the transient of large break LOCA. To determine the feasible configuration and capacity of SIT and HPSI pump with the elimination of the Low Pressure Safety Injection (LPSI) pump for KNGR, licensing design basis evaluations are performed for the limiting large break LOCA. The study shows that the DVI injection with the fluidic device SIT enhances the SIS performance by allowing more effective use of borated water for an extended period of time during the large break LOCA.

  • The FISPACT-II inventory simulation platform is a modern computational tool with advanced and unique capabilities. It is sufficiently flexible and efficient to make it an ideal basis around which to perform extensive simulation studies to scope a variety of responses of many materials (elements) to several different neutron irradiation scenarios. This paper briefly presents the typical outputs from these scoping studies, which have been used to compile a suite of nuclear physics materials handbooks, providing a useful and vital resource for material selection and design studies. Several different global responses are extracted from these reports, allowing for comparisons between materials and between different irradiation conditions. A new graphical output format has been developed for the FISPACT-II platform to display these "global summaries"; results for different elements are shown in a periodic table layout, allowing side-by-side comparisons. Several examples of such plots are presented and discussed.
