Linearity of reactor

Anionic and non-ionic surfactants have been detected in the influents to and effluents from wastewater treatment plants (WWTPs). Linear alkylbenzene sulphonates (LAS) and alkylphenol ethoxylates (APEO) are the most frequently detected anionic and non-ionic surfactants in urban wastewater. The aim of this study was to assess the effect of the presence of anionic and non-ionic surfactants in the influent to WWTPs on activated sludge processes.

We study axial core oscillations due to xenon poisoning in thermal neutron nuclear reactors with simple 1D models: a linear one-group model, a linear two-group model, and a non-linear model taking the Doppler effect into account.

In the present paper, firstly, we review our previous works on uncertainty quantification (UQ) of reactor physics parameters. This consists of (1) development of numerical tools based on the depletion perturbation theory (DPT), (2) linearity of reactor physics parameters to nuclear data, (3) UQ of decay heat and its reduction, and (4) correlation between decay heat and b-delayed neutrons emission.
