Gas-Cooled Reactor Technology

The Sodium-cooled Fast Reactor (sfr)

The Sodium-cooled fast reactor (SFR) features a closed fuel cycle for efficient conversion of fertile uranium and management of minor actinides. A full actinide-recycle fuel cycle is envisioned with two major options: One involves intermediatesized (150 to 500 MWe) sodium-cooled fast reactors with uranium-plutonium-minor-actinidezirconium metal alloy fuel, supported by a fuel cycle based on pyr...

Design of Chinese Modular High-temperature Gas-cooled Reactor Htr-pm

Modular high-temperature gas-cooled reactor (MHTGR) has distinct advantages in the sense of the inherent safety, economy property, high electricity efficiency, potential usage for hydrogen production, and etc. Chinese design of MHTGR, named as High Temperature Gas-Cooled Reactor-Pebble bed Module (HTR-PM), based on the technology and experiences of the HTR-10, is under the standard design phase...

A Particle-bed Gas-cooled Fast Reactor Core Design for Waste Minimisation

The issue of waste minimisation in advanced reactor systems has been investigated using the Particle-Bed Gas-cooled Fast Reactor (PB-GCFR) design being developed and funded under the U.S. Department of Energy Nuclear Energy Research Initiative (USDOE NERI) Programme. Results indicate that for the given core power density and constraint on the maximum TRU enrichment allowable, the lowest amount ...

Adaptive Polynomial Chaos Techniques for Uncertainty Quantification of a Gas Cooled Fast Reactor Transient

Uncertainty quantification plays an increasingly important role in the nuclear community, especially with the rise of Best Estimate Plus Uncertainty methodologies. Sensitivity analysis, surrogate models, Monte Carlo sampling and several other techniques can be used to propagate input uncertainties. In recent years however polynomial chaos expansion has become a popular alternative providing hig...
