A recurrent multilayer perceptron (RMLP) model is designed and developed for simulation of core neutronic phenomena in a nuclear power plant, which constitute a non-linear, complex dynamic system characterized by a large number of state variables. Training and testing data are generated by REMARK, a rst principles neutronic core model 16]. A modiied backpropagation learning algorithm with an ad...

A preliminary comparative assessment relevant to the transmutation efficiency of plutonium and minor actinides has been performed in the case of ANSALDO’s Energy Amplifier Demonstration Facility based on molten lead-bismuth eutectic cooling, classical MOX-fuel technology and operating at 80 MWth. The neutronic calculations presented in this paper are a result of a state-of-the-art computer code...

A code called UNÌC is currently under development at Argonne National Laboratory (ANL). The aim of the code is to provide a neutronic solver with the same geometrical flexibility of Monte Carlo codes and without the approximations (homogenization and energy condensation) associated with the common multi-step approach currently used. Moreover, UNÌC will offer the capability of multi-resolution i...

It is proposed in this paper the automatic detection thresholds in the neutronic noise from a nuclear reactor chamber. The proposed method combines a pattern recognition algorithm, known as dynamic cluster and a linear programming algorithm. Euclidean distance, often adopted by default, in the dynamic cluster algorithm; is here replaced by the distance L1, also called least absolute deviations ...

The presented paper is related to introduction of the design and neutronic characterization start-up core developed for Gas cooled Fast Reactor (GFR) demonstrator. Slovak University Technology in Bratislava joined project ALLEGRO last decade within consortium middle-European institutions. In development plan GEN IV GFR demonstrator one most necessary steps. reactor small helium 75 MWth thermal ...
