چکیده

This work deals with the assessment of burnup capabilities Serpent Monte Carlo code to predict spent nuclear fuel (SNF) isotopic concentrations for low-enriched uranium (LEU) at different levels up 47 MWd/kgU. The irradiation six UO2 experimental samples in three VVER-1000 reactor units has been simulated and predicted actinides 244Cm have compared corresponding measured values. results show a global good agreement between calculated concentrations, several cases within margins data uncertainties few even reported uncertainties. differences performances JEFF3.1.1, ENDF/B-VII.1 ENDF/B-VIII.0 libraries (NDLs) also assessed use newly released library shown an increased accuracy prediction C/E's some considered, particularly plutonium isotopes. represents step forward towards validation advanced simulation tools against post obtained provide evidence Monte-Carlo associated modern NDLs accurately compute SNF nuclide inventory type reactors.

A Monte Carlo Burnup Code Linking Mcnp and Rebus*

The REBUS-3 burnup code, used in the ANL RERTR Program, is a very general code that uses diffusion theory (DIF3D) to obtain the fluxes required for reactor burnup analyses. Diffusion theory works well for most reactors. However, to include the effects of exact geometry and strong absorbers that are difficult to model using diffusion theory, a Monte Carlo method is required. MCNP, “a general-pur...

Modeling the measurement of VVER-1000 reactor power by neutron and gamma radiation with MCNP code

The present study deals with a new method for measuring the power of a reactor. This method uses gamma and neutron radiation resulted from the entire reactor structure, without changing its structure (online). In terms of functionality, this method can measure the reactor power in real-time and report it instantly. In order to obtain the relationship between reactor power and gamma and neutron ...

Estimation of Photon Specific Absorbed Fractions in Digimouse Voxel Phantom using Monte Carlo Simulation Code FLUKA

Background: Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs.Objective: SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV...

Assessment of secondary particles in breast proton therapy by Monte Carlo simulation code using MCNPX

Background: The present study aimed to investigate the equivalent dose in vital organs, including heart and lung, due to secondary particles produced during breast proton therapy. Materials and Methods: The numerical ORNL female-phantom was improved and simulated using the Monte Carlo MCNPX code. The depth-dose profile of proton beams with different energies was simulated. The proper energy ran...
