The High Temperature Gas-cooled Reactor (HTGR) is particularly attractive due to its capability of producing high temperature helium gas and inherent safety characteristics. These interesting aspects make HTGR worthy of discussion on the future advanced reactors. The Japanese interest in the HTGR has resulted in the construction of the High Temperature Engineering Test Reactor (the HTTR) at the...
The high temperature gas-cooled reactor (HTGR) is a graphite moderated, helium cooled reactor with ceramiccoated fuel particles (TRISO fuel particles). The HTGR is inherently safe and expected to be applied to various industrial fields such as electric generation, hydrogen production, etc. with high efficiencies. It is also recognized as a representative advanced nuclear system for the future. ...
► The new HTGR + MED coupling scheme was proposed. ► KAIST coupling scheme uses PCHE without any intermediate loop. ► KAIST coupling scheme has independent structure between MED and heat sink. ► Water production capacity increases by 258% compared to previous researcher's results. ► Water cost is reduced by 9.0% compared to previous researcher's results. a b s t r a c t a r t i c l e i n f o Th...
A conceptual design for a small HTGR in the 100 MWe size range is described. The reactor drives indirect closed-cycle gas turbine power conversion units using helium as the working fluid and provides both electricity and thermal energy (via a 3800 F hot-water utility system) to serve the projected needs of large U.S. Army installations and industrial facilities in the continental U.S. in the po...
Nodal expansion method (NEM) is a typical nodal in solving neutron diffusion equation coarse mesh spatial discretization. NEM has been extended to cylindrical geometry previous studies. Cylindrical can be realized by different forms, where the variables coupling equations are classified as net current, flux or partial current at surface, respectively. The three types of forms have implemented P...
Progress continued on method development for the dissolution of difficult-to-dissolve materials, the automated analysis of plutonium and uranium, the preparation of plutonium materials for the Safeguard Analytical Laboratory Evaluation (SALE) Program, and the analysis of HTGR fuel and SALE uranium materials. The previously developed Teflon-container, metal-shell apparatus was applied to the dis...
The inherent passive heat removal characteristics of modular High Temperature Gas-Cooled Reactors (HTGRs) are well known. Modular HTGRs use a combination coated-particle fuel, ceramic core materials, geometry, and power level to maintain acceptable fuel temperatures for all credible operating accident conditions. Heat from the reactor vessel is radiated cavity cooling system (RCCS), which remov...
Abstract High Temperature Gas-cooled Reactor (HTGR), which has well-known safety features and high temperature heat supply capability, is expected to be widely used for technology utilization including the hydrogen production, so contributing reduction of carbon dioxide emissions in various sectors. The 10 MW gas-cooled test (HTR-10) had been constructed operated China as a pilot plant demonstr...
