Neutronic Decoupling Characteristics of Large Fast Reactor Cores

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...

Monte Carlo Neutronic Analysis of A Loosely Coupled Reactor*

Neutronic Analysis on a Low Enriched Uranium Coupled Reactor Consisting of Pulse Cores and a Laser Module

A highly enriched uranium coupled reactor consisting of pulse cores and a laser module is known as one of the reactors for nuclear-pumped laser. Neutronic analysis on a low enriched uranium coupled reactor which consists of pulse cores and a laser module was performed. Calculation results showed that a low enriched uranium coupled reactor could achieve criticality by using several expanded puls...

Decoupling Cores, Kernels, and Operating Systems

We present Barrelfish/DC, an extension to the Barrelfish OS which decouples physical cores from a native OS kernel, and furthermore the kernel itself from the rest of the OS and application state. In Barrelfish/DC, native kernel code on any core can be quickly replaced, kernel state moved between cores, and cores added and removed from the system transparently to applications and OS processes, ...

Advanced Fast Reactor:

The AFR concept is being developed at Argonne National Laboratory, as an extension of earlier work done on the Integral Fast Reactor (IFR). That work was undertaken specifically to resolve some pressing technical issues in safety, waste management, nonproliferation, and economics. Also important, however, was the fundamental fact that the efficient utilization of uranium resources is crucial to...
