Serpent-2 Reactor Model Validation at the Vienna Triga Mark Ii Reactor
نویسنده
چکیده
The Vienna TRIGA Mark II reactor was modelled by means of the Serpent-2 Monte Carlo burnup calculation code. The purpose of the modelling is the determination of core critical parameters and of nuclear fuel composition time evolution. This paper presents the Serpent-2 reactor model validation process carried out during the last year. Taking into account the irradiation history, the fuel composition was calculated for a certain number of fuel elements in the current core. The fuel elements were selected in order to sample the different core areas, rising from internal B ring to the external part of the core. Subsequently, the calculation results were compared with different fission product activity values measured in the corresponding fuel elements. The measurement campaign was previously performed by means of a fuel gamma-scanning machine installed at the reactor as presented at the RRFM 2016. The comparison of fission products activity values obtained by Serpent-2 model calculation and by direct measurements are presented in this paper.

Neutronics Analysis of the TRIGA Vienna Mixed Core
The 250 kW TRIGA Mark II research reactor, Vienna, operates since 7 March 1962. The initial criticality was achieved with the first core loading of 57 fuel elements (FE) of same type (Aluminium clad fuel with 20% enrichment). Later on due to fuel consumption SST clad 20% enriched FE (s) have been added to compensate the reactor core burn-up. In 1975 high enriched (HEU) TRIGA fuel (FLIP fuel = F...

This paper presents an algorithm for numerical simulations of nonsteady states of the TRIGA MARK II reactor in Vienna, Austria. The primary focus of this work has been the development of an algorithm which provides time series of integral neutron flux after reactivity changes introduced by perturbations without the usage of thermal-hydraulic / neutronic numerical code systems for the TRIGA reac...

In this work, it has been shown that the time dependent Xe inventory in the TRIGA Mark II reactor in Vienna, Austria can be measured via gamma spectrometry even in the presence of strong background radiation. It is focussing on the measurement of (but not limited to) the nuclide Xe. The time dependent Xe inventory of the TRIGA Mark II reactor Vienna has been measured using a temporary beam line...
متن کاملAccident scenarios of the TRIGA Mark II reactor in Vienna
The safety report of the TRIGAMark II reactor in Vienna includes three accident scenarios and their deterministic dose consequences to the environment. The destruction of the cladding of the most activated fuel element, the destruction of all fuel elements and a plane crash were considered scenarios in that report. The calculations were made in 1978 with the software program named STRISK. In th...
