Book excerpt: The Modular High-Temperature Gas-Cooled Reactor (MHTGR) is an advanced power plant concept which has been under design definition since 1984. The design utilizes basic high-temperature gas-cooled reactor features of ceramic fuel, helium coolant and a graphite moderator which have been under development for 30 years. The geometric arrangement of the reactor vessels, the core and the heat removal components has been selected to exploit the inherent characteristics associated with high temperature materials. The design utilizes passively safe features which provide a higher margin of safety and investment protection than current generation reactors. The design has been evaluated to be economically attractive relative to modern coal fired plants. The design and development program is a cooperative effort by the US government, the utilities and the nuclear industry. 8 refs., 4 figs., 4 tabs.

Download or read book The Modular High Temperature Gas-cooled Reactor (MHTGR) Containment Trade Study written by . This book was released on 1990. Available in PDF, EPUB and Kindle. Book excerpt: The modular high temperature gas-cooled reactor (MHTGR) is an advanced reactor concept under development in a cooperative program involving U.S. government, the nuclear industry, and the utilities. The design utilized the basic hig-temperature gas-cooled reactor features of ceramic fuel, helium coolant, and a graphite moderator. The key design parameters, including power, power density, and core and configuration of the MHTGR are selected to utilize the inherent properties of these materials to develop passive safety features that provide a significantly higher margin of safety than current generation reactors. In this paper the reference MHTGR module is combined with several alternatives, each characterized by an alternative containment building structure providing differing degrees of radionuclide containment. The reference design and each alternate are described and their performance compared. The MHTGR radionuclide source and how it related to the radionuclide retention provided by buildings and building features are discussed. This is followed by more detailed considerations leading to the selection of five alternatives. The underlying assumptions and approach employed in assessing alternative designs are summarized. The evaluation of the cost and offsite does reduction benefit of the reference design and selected alternatives are described. Finally, the various alternatives are compared with each other allowing conclusions to be drawn. All design concepts meet the U.S. Environmental Protection Agency's Protective Action Guidelines at the site boundary hence precluding the need for emergency drills, sheltering, or evacuation of the public.

Download or read book Research and Development Associated with Licensing of MHTGR (Modular High Temperature Gas-Cooled Reactor). written by . This book was released on 1990. Available in PDF, EPUB and Kindle. Book excerpt: The Modular High Temperature Gas-Cooled Reactor (MHTGR) currently under development by the US Department of Energy (US-DOE) for commercial applications has top-level goals of producing safe, economical power for the US utility industry. The utility industry has been represented in formulating design and licensing requirements through both a Utility User Requirements Document'' and by participating in the DOE system engineering process known as the Integrated Approach.'' The result of this collaboration has been to set stringent goals for both the safety and operational reliability of the MHTGR. To achieve these goals, the designer must have access to a more comprehensive data base of properties in several fields of technology than is currently available. A technology development program has been planned to provide this data to the designer in time to support both his design activities and the submittal of formal licensing application documents. The US-DOE has chosen the Oak Ridge National Laboratory (ORNL) to take the lead in planning and executing these technology programs. When completed these will augment the designer's current data base and provide the necessary depth to meet the stringent goals which have been set for the MHTGR. It is worth noting that the goals of safety and operational reliability are complementary, and the data required from the technology development program will be similar. Therefore, the program to support the licensing of the MHTGR is not separate from that required for design, but is a subset of that which meets all the requirements that result from implementing the US-DOE's integrated approach. 38 figs.

Book excerpt: "Modular High-temperature Gas-cooled Reactor Power Plant" introduces the power plants driven by modular high temperature gas-cooled reactors (HTR), which are characterized by their inherent safety features and high output temperatures. HTRs have the potential to be adopted near demand side to supply both electricity and process heat, directly replacing conventional fossil fuels. The world is confronted with two dilemmas in the energy sector, namely climate change and energy supply security. HTRs have the potential to significantly alleviate these concerns. This book will provide readers with a thorough understanding of HTRs, their history, principles, and fields of application. The book is intended for researchers and engineers involved with nuclear engineering and energy technology.

Book excerpt: This paper presents the approach used to define the technology program needed to support design and licensing of a Modular High-Temperature Gas-Cooled Reactor (MHTGR). The MHTGR design depends heavily on data and information developed during the past 25 years to support large HTGR (LHTGR) designs. The technology program focuses on MHTGR-specific operating and accident conditions, and on validation of models and assumptions developed using LHTGR data. The technology program is briefly outlined, and a schedule is presented for completion of technology work which is consistent with completion of a Final Safety Summary Analysis Report (FSSAR) by 1992.
