Monte Carlo Neutronic Analysis of A Loosely Coupled Reactor*

Neutronic Design of the Pb-ahtr

This study (1) investigates the neutronic characteristics of the Pebble Bed Advanced High Temperature Reactor (PB-AHTR); (2) compares the PB-AHTR neutronic performance against those of the alternative design options of He-cooled high temperature reactors using either pebble (PBMR) or prismatic (VHTR) fuel and against a liquid-salt cooled design version of the latter (LS-VHTR); (3) studies the p...

Numerical simulation of long and slender cylinders vibrating in axial flow applied to the MYRRHA reactor

Flow induced vibrations are an important concern in the design of nuclear reactors. One of the possible designs of the 4th generation nuclear reactors is a lead-cooled fast reactor of which MYYRHA is a prototype. The combination of high liquid density, flow velocity, low pitch-todiameter ratio and the absence of grid spacers makes this design prone to flow induced vibrations. Although most vibr...

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...

Coreless Hall Effect Based Current Sensing Technique with Magnetic Shielding

In this modern era, most of the equipment is electrostatic type. But still, in measuring current, we use conservative type. So, we developed a Modified coreless Hall Effect based current sensing method with magnetic shielding. The coreless Hall Effect based measurement method uses hall sensors without iron core. Hall sensors are firmly fixed on the insulated current carrying conductor. The magn...
