The government of the Republic of Korea, as a contracting party to the Joint<br/>Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive<br/>Waste Management (hereinafter referred to as “Joint Convention”) which entered into<br/>force on June 18, 2001, and deposited the ratification of on September 16, 2002,<br/>described the state of implementing the contracting party’s obligations in the Third<br/>National Report, pursuant to Article 32 (Reporting) of the Joint Convention.<br/>This National Report was prepared in accordance wi

The Korean government has maintained a consistent national policy for stable energy supply by fostering nuclear power industries under the insufficient energy resources in the country. Nuclear power reached approximately 40 % of total domestic electricity generation. Since the commencement of the first commercial operation of Kori Unit 1 in April 1978, 20 units of NPPs are commercially operating as of October 2005. Four units out of the 20 operating NPPs are Pressurized Heavy Water Reactors (PHWRs) at Wolsong.

This study presents a synthesis of information and interpretations relevant to surficial processes at the Yucca Mountain Site. The report is part of the technical basis which will be used to evaluate the suitability of Yucca Mountain, Nevada, as a site for a mined geologic repository for the permanent disposal of high-level radioactive waste and spent nuclear fuel. It provides a description of the surface characteristics, preclosure hydrology, and erosion at the Yucca Mountain Site. This report will provide the technical basis to evaluate three technical guidelines from the U.S.
