The effects of fuel type on control rod reactivity of pebble-bed reactor

Nukleonika, 2019
As a crucial core physics parameter, the control rod reactivity has to be predicted for the control and safety of the reactor. This paper studies the control rod reactivity calculation of the pebble-bed reactor with three scenarios of UO2, (Th,U)O2, and ...

Isotope-producing control rods [PDF]

, 1959
In accordance with the NPR technical criteria which require that provisions be made for useful isotope production in the control rods, both isotope-producing and non-production rods have been designed. Design Analysis has been requested by Reactor Plant Design to specify the number and location of the isotope rods for the initial installation.

Design of a compact digital to analog converter with optical Kerr effect

Scientific Reports
This article presents a novel 2-bit digital-to-analog converter design based on photonic crystals. In this structure, a nonlinear Kerr effect has been considered to transfer the light intensity inside the ring resonator, which can control the optical ...
