Project Title Study on the Evaluation of Decontamination & Decommissioning Technologies and Their Demands in Korea 2. Objectives of the Project Most of the developed countries including USA, UK and France are expected to stop construction of new nuclear power plants for the time being and to extend the existing NPP and also to decommission the nuclear facilities mainly related to the back end nuclear fuel cycle development activities. Decontamination and decommissioning (D&D) in these countries becomes one of the most important nuclear industry. D&D of the TRIGA MARK II and III, the first nuclear reactor in Korea has been already started. Considering the importance of the decontamination and decommissioning, it is time to launch the national D&D technology development program. The purpose of the study is to evaluate the D&D technology demand and its current status to screen the necessary technologies for the national R&D program and then is to identify the development circumstance and future prospects of the selected technologies necessary to the R&D planning. 3. Contents and Scope of the Study D&D market in Korea as well as abroad was classified into three fields such as a research reactor, a commercial nuclear power plant and a nuclear fuel cycle and then forecasted by 2010 as a short term demand and also by 2030 as a long term demand. A technology tree diagram was developed by classifying into the lower level of the technologies up to 3 or 4 level and then the current status of the final technology items were evaluated by using the evaluation criteria. KOPEC select the technologies subject to development in the short term and also in the long term. The short term('01-06) development v technologies were further analyzed into its technology tree and then evaluated their future prospects. IV. Results The domestic D&D market ie expected to increase gradually in the future and the large D&D market has been already formulated abroad, especially in the U. S. A. mainly for the nuclear fuel cycle facilities. The short term D&D needs in the country will be the decommissioning for the TRIG A research reactors and the uranium conversion facility we are facing, the back end nuclear fuel cycle development facilities for maintenance and refurbishment, and the nuclear power plants for operation and maintenance including the plant life time extension. The demand of the nuclear fuel cycle R&D facilities in North Korea also will be gradually increased depending on the reunification of the Korean peninsular. The short term R&D items were selected using the above results by KOPEC. The technology tree was analyzed in the study as follows: Level 0 Level 1 Level 2 Source temVd • D&D source term evaluation Characterization residual nuclide • Residual nuclide evaluation after decommissioning evaluation Dry decontamination • Unite decontamination using RFC, CCyand plasma Decontamination applicable to highly • In-situ decontamination in the hot cell technologies active radiation • ReusUwaste down-grade decent, after transportation • 3 dimensional laser cutting technology Dismantling and Laser dismantling • mobile remote robots remote operation and remote operation • TRIGA remote metal cutting demonstration Sludge treatment decommissioning • Uranium sludge waste treatment and metallic waste waste mangmnt • Metallic waste reduction and reuse reuse Environment Soil decontamination • Soil waste decontamination restoration and restoration • Site restoration and TRIG demonstration TIOGA • Automatic surface contamination measure equipment decommissioning • RSR under water dismantling equipment Immediate national application field • Mobile remote radiation survey equipment D&D project • Activated graphite treatment TRIGA application • Activated concrete degradation ageing decommissioning • Activated metal degradation by ageing related R&D • TRIGA D/B and computer dismantling simulation vi The short term R&D is expected not only to apply to the current D&D projects but also to contribute to the national fuel cycle development and also to the technology exports in the future. V. Proposals for Application The results will be used to establish the national long term R&D planning on 'Decontamination and Decommissioning Technologies'. CONTENTS CHAPTER I.

It represents the results of the inquiry by the Thorium Systems Task Force whose membership included representatives of Babcock & Wilcox Company, Gulf General Atomic Company, the Argonne National Laboratory, the Brookhaven National Laboratory, the Oak Ridge National Laboratory, the Pacific Northwest Laboratory, and the U.S. Atomic Energy Commission. Publication of this report, which provides information basic to the AEC reactor development program, completes one phase of the evaluation effort outlined in the 1967 Supplement to the 1962 Report to the President on Civilian Nuclear Power, issued in February 1967. The 1967 Supplement outlined changes since 1962 in the technical, economic and resource picture and provided background for further study. Specifically, this report represents the consensus of the task force on the potential use of the thorium cycle and the specific thorium fueled reactor designs which have been proposed.

RESUME :O n décrit un programme d'essais non destructifs pour examiner les elements combustibles de réacteur en (U.Zr)C-C. I. INTRODUCTION The Los Alamos Scientific Laboratory has been active for the past twenty years in the development and testing of graphitic-based high temperature reactor fuel elements. The initial involvement was in the field of nuclear propulsion systems. Project Rover began as a program to develop a nuclear-powered, hydrogen-propelled rocket engine. The target exhaust temperature of the propellant was about 2775 K. The fuel element for such an engine would have to maintain its integrity and strength at higher temperatures and would have to resist currosion by the hot hydrogen gas, which is very reactive. These constraints limited the choice of materials to a very few. Carbon melts above about 3800 K, has excellent high-tenperature strength, and is not a strong neutron absorber. It is very reactive to high temperature hydrogen. The basic fuel element foi the Rover Program became uranium-loaded graphite. The enriched uranium fuel was incorporated into the graphite matrix as uranium oxide, later as py- rolytic-carbon coated uranium dicarbide inicrospheres, and, aosf recently, as a solid solution of uranium carbide and zirconium carbide.

INTRODUCTION History of the Proposal to Cut Off the Production -of Fissile Material for Nuclear Weapons Although the original nuclear weapons control proposals such as the 1946 Baruch Plan - focused on the control of nuclear weapons materials, recent arms control negotiations have focused principally on the control of long-range nuclear weapons delivery systems. This has been in part due to the shift in the focus of the nuclear arms race from the quantitative to the qualitative. In part also it resulted from the Soviet Union's reluctance to allow intrusive verification arrangements.

Of course, there are a great many “nuclear fuel cycle” scenarios to consider; if not in practice, then at least in theory. The simplest conceptually is the “once through” fuel cycle in which the spent fuel is discarded.

In 1970 this Laboratory was still largely a weapons lab, but Livermore was doing a better. more aggressive selling job and was pushing for the enhanced radiation weapons and all the strategic weapons—the nuclear warheads for Minuteman and Polaris. Their reputation was better than ours, or at least perceived to be so by some people. Harold’s vision was to restore the luster that Los Alamos had lost. It’s true that he thought the Laboratory was premier in all fields and he would undertake anything, but above all he wanted to be first in our principal mission of weapons develop- ment, SCHREIBER: There’s another aspect to the Bradbury-Agnew transition that I feel is also important to recognize, At the end of World War 11, when Norris became Director, a lot of people who had served during the war years on Laboratory advisory boards simply disappeared.
