This paper deals with the result of an analysis on the effect of the power generation by municipal solid waste(MSW)-refuse derived fuel(RDF) and the introduction of tipping fee sharing between RDF manufacturing and power generation project. As a model case for the MSW generated at small and medium cities in our country, an analysis of the RDF power generation and Tipping fee sharing shows that 1) MSW amount of 7,800* $10^3 $t/y could produce 1,950*$10^3$t/y of RDF 2) Electric power generated by MSW-RDF could supply 290,000 households/year and 98,548 C-t/y of $CO_2$ could be reduced. 3) Tipping Fee should be shared by the considering of the contents of project of both side between RDF Production and power generation.

This study investigated the status of resident participation in the policy of supplying new and renewable energy in rural areas. According to the survey, most of the rural residents were well aware of the new and renewable energy supply project promoted by the government. However, it was found that participation in the project was difficult mainly for economic and social reasons. In order to activate the participation of rural residents who can't participate in the renewable energy power generation project for economic and social reasons, it is necessary to develop and promote business models and support policies for power generation projects in which village communities participate. Changes in residents' acceptability due to resident education and operation for solar power systems were analyzed. As a result of the survey, it was found that the satisfaction of rural residents was high when new and renewable energy power generation projects were introduced in rural areas. Therefore, it is thought that the government's goal of increasing farm household income and expanding the supply of new and renewable energy in rural area can be successfully achieved by the improvement of resident acceptability and the increase of the participation rate. Lastly, this study presented a plan to improve the resident acceptability of the renewable energy system by using the rural solar project and survey results.

Solar thermal power generation allows additional benefits of cheap thermal storage and easy hybridization with other fossil fuel-driven power generation. KIER has been performing the project for solar thermal chemical reaction hybrid power generation. The project is to build and operate the first solar thermal chemical reaction hybrid power generation system in Korea. For concentrating solar thermal energy $m^2$ dish type concentrator was adapted and a heliostat is installed for reflecting horizontal insolation to the dish concentrator. At the moment building the dish concentrator including mirror and heliostat with sun tracking system was completed and it's performance are being closely evaluated. This paper will introduce some detailed designs and construction procedures which we have experienced so far.

Maximum power consumption was up to 6,228kW in the summer of 2007 due to steady development of industry as well as increased demand of individual. Twenty fossil-Fired Thermal Power Plant for 500MW were underconstructed at present. KEPRI(Korea Electric Power Research Institute) manage 'Development of Advanced Fossil-Fired Thermal Power Generation System' project to construct high efficient power plant of 1000MW capacity for preparing increased demand of power. Design of control logic and data sampling were explained and high efficient control logic was simulated in detail in 'The Development of Next Generation Power Plant Instrument and Control System'(sub-project of 'Development of Advanced Fossil-Fired Thermal Power Generation System' project).

The growing demand for new energy infrastructure has often been encountered with the difficulties of siting in power plants and electric transmission lines. Siting such large-scale and complex facilities produces so many-sided issues that it is highly necessary to develop an approach to resolving the related problems and conflicts. This paper introduces how the stakeholders have handled the issues and resolved conflicts with residents opposed the construction of 765 kV transmission line. The solar photovoltaic power generation, called "Hee-Mang Sunlight Power project", is used for persuading residents to agree with constructing high-voltage transmission line and sharing benefits. It is considered how the project performance such as generation output and resident's profits is and proposed what the project should be revised and supplement. The project is shown that the intractable spiting in energy systems can be smartly resolved with cost-effective institutional solutions instead of relatively expensive technical ones.

KIER have been developing high-temperature solar technology, especially the solar thermal power generation system, since the early of 1990s. In 1994, the first research on high temperature solar technology started with PTC technology. At the moment the most advanced 10kW dish system is under demonstration for 10kW solar thermal power generation. Test results showed about 19.2% solar to electricity average efficiency. Another research activities of KIER is hybrid power generation. For hybridization, solar and LFG(landfill gas) are used. Another hybrid solar system is with solar chemical reaction. In this system, power unit is gas turbine, and the heat content of fuel(like natual gas) is upgraded by solar energy through chemical reaction. The latest project on solar thermal power generation is for 1 MW power tower system. This is the Korea-China Joint project.

This research documents the initial findings and recommendations for developing a risk management tool to assess and quantify the risks associated with the construction of the next generation of nuclear power plants. The proposed tool builds upon the Construction Industry Institute's International Project Risk Assessment (IPRA) Best Practice. This paper provides an overview of the investigation to assess the unique risk elements pertaining to nuclear power plant construction and documents the preliminary findings from historical project performance data to better understand the function and use of the IPRA's Relative Impact value.

2010년 12월에 착수한 인공 지열 저류층 생성기술(EGS)를 이용한 지열발전 pilot plant 프로젝트에서 계획된 5 km 깊이의 doublet 시스템에서 실현 가능한 발전량 목표를 추정하였다. 지하 5 km 에서의 암반 온도는 경북 포항지역의 평균 지온증가율은 $33^{\circ}C$/km로 하였을 때 지표온도를 감안하면 $180^{\circ}C$로 추정된다. 암반과의 열교환을 통해 생산되는 지열수의 온도를 $160^{\circ}C$, 발전 후 주입수의 온도를 $60^{\circ}C$로 생각할 수 있고, 이때 binary 발전의 열효율은 0.11이 가능하다. 최근의 EGS에서 실현 가능한 생산 유량인 40 kg/sec을 가정한다면 총 발전량은 1.848 MW로 계산되며, 지열수 양수 펌프와 binary 발전의 냉각에너지 소요량을 고려하면 순 발전량 1.5 MW가 가능해진다.
