“…In recent work alpha was estimated with plant data using Detrended Fluctuation Analysis (DFA) [9], which was applied to a neutronic power signal of the Forsmark stability benchmark and Laguna Verde Nuclear Power Plant. According with these DFA results, a ranges between 0.1881 and 0.9399 were found, which consider different operation of the reactor, such as stationary operation, load changes and unstable conditions due to wave density phenomena.…”

“…In order to model the anomalous diffusion process, a new version of the diffusion equation has been developed based on the fractional derivatives. Neutron fractional diffusion equation was derived by Espinosa-Paredes [9]:…”

“…Moreover numerical solutions of conservation equations, with variable coefficients in the heterogeneous media, need to be matured. In order to core calculation in the nuclear reactors there is a new version of the neutron diffusion equation which is established on the fractional space derivatives (Maleki Moghaddam et al, 2014;Espinosa-Paredes et al, 2013).The neutron fractional diffusion equation, NFDE, uses the non-local gradient of Fick's law (J = ÀD a r a /) where the fractional derivative operator, r a , can be defined in the Riemann-Liouville, Caputo and Grünwald-Letnikov sense (Das, 2012;Oldham and Spanier, 1974;Hilfer, 2000;Miller and Ross, 1993) and a is the order of fractional derivatives. In the limit a ?…”
