Superheated Water-Cooled Small Modular Underwater Reactor Concept

Separations Using Superheated Water

Superheated water is liquid water under pressure between 100°C and its critical temperature of 374°C. The rationale for using superheated water is explained. An overview of the work on its use for separation processes is given. The work that has been carried out is mostly of laboratory scale, although some pilot studies and small industrial processes are described. INTRODUCTION It is useful to ...

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...

UWFDM-1256 A Lithium Self-Cooled Blanket Concept for the HAPL Conceptual Inertial Confinement Reactor

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...

Neutronic Study of Two Reactor Cores Cooled with Light and Heavy Water Using Computation Method

Most HWRs currently use natural uranium fuel. Using enriched uranium fuel results in a significant improvement in fuel cycle costs and uranium utilization. On the other hand, reactivity changes of HWRs over the full range of operating conditions from cold shutdown to full power are small. This reduces the required reactivity worth of control devices and minimizes local flux distribution perturb...
