INL Advanced Reactor Technologies

  
IntroMessage
  
Advanced Reactor Technologies (ART)  is a national program funded by the U.S. Department of Energy (DOE). Here at INL, work is focused specifically on developing a High Temperature Gas-cooled Reactor (HTGR), which will offer enhancements in safety and efficiency. This HTGR has a modularized design, which enables plants with larger power demands to simply build more than one module.  Modularization requires no extra design work and increases safety and efficiency by allowing a singular module to run or be stopped at any given time in the event of an incident or a changing need for power. HTGRs also produce process heat during operation, making them ideal for location near other industrial plants that could put this process heat to use in their own production and thus reduce the need for non-renewable energy sources upon which these plants currently rely.

The idea of a nuclear reactor operating at high temperature was first conceived in the early days of nuclear power plant development.
The idea of a nuclear reactor operating at high temperature (>700C) was first conceived in the early days of nuclear power plant development and government programs were instituted to develop the fuels, materials, and power conversion systems that could withstand these temperatures.

FullStory
  
TRi-structural ISOtropic particle fuel — or TRISO, for short — is a type of micro fuel particle, quite possibly the most robust type of nuclear fuel.
  
Tristructural isotropic (TRISO) coated particle fuel is the key fuel concept for the high-temperature gas-cooled reactors (HTGRs), selected by the US Department of Energy (US-DOE) [1]. A TRISO fuel particle consists of a fuel kernel of UO2 or UCO and multiple coatings of a porous graphite buffer layer, inner pyrolytic carbon (IPyC) layer, silicon carbide layer as the primary pressure vessel, and a dense outer pyrolytic carbon (OPyC) layer.
  
The objective of this study is to develop a 3D neutron kinetic (NK) and thermal hydraulic (TH) coupled model using the INL developed code RELAP5-3D©/PHISICS to study the load following operation of a Modular High-Temperature Gas-Cooled Reactor (MHTGR).
  
Today, the U.S. Department of Energy (DOE) announced more than $65 million in nuclear energy research, cross-cutting technology development, facility access, and infrastructure awards for 93 advanced nuclear technology projects in 28 states.
