Measurements of Subcritical Reactor Noise Spectra by Correlation Method

Cambridge 39 , Massachusetts MEASUREMENTS OF REACTOR PARAMETERS IN SUBCRITICAL

A new correlation method for high sensitivity current noise measurements.

The properties of a differential transconductance amplifier coupled with a four channel measurement system are exploited in order to reach a very high sensitivity in current noise measurements. In particular, it is demonstrated that, in proper conditions, the noise contributions coming from the active and passive devices that make up the transresistance amplifier can be virtually eliminated. Mo...

Understanding the amplitudes of noise correlation measurements

[1] Cross correlation of ambient seismic noise is known to result in time series from which station‐station travel‐time measurements can be made. Part of the reason that these cross‐correlation travel‐time measurements are reliable is that there exists a theoretical framework that quantifies how these travel times depend on the features of the ambient noise. However, corresponding theoretical r...

Modeling of the Hydrocracking Reactor by the CESE Method

In this article, the improved space-time conservation element and solution element (CESE) method are used to simulate the dynamic treatment of the hydrocracking reactor. The dynamic model consists of four lumps: vacuum gas oil (VGO), middle distillate, naphtha, and gas which is dissolved by this method. The offered method can solve the partial differential equations caused by the reactions insi...

Study on Neutronics Design of an Accelerator Driven Subcritical Reactor

Thorium fueled Accelerator Driven Subcritical Reactors have been proposed as a more comprehensive alternative to conventional nuclear reactors for both energy production and for burning radioactive waste. Several new classes have been added by the authors to the GEANT4 simulation code, an extension which allows the state-of-the-art code to be used for the first time for nuclear reactor critical...
