Fuel cycle simulators are used worldwide to provide scientific assessment fuel future strategies. Those tools help understanding the physics and determining most impacting drivers at scale. A standard scenario calculation is usually based on a set of operational assumptions, such as reactor Burn-Up, deployment history, cooling time, etc. Scenario output then evolution isotopes mass in facilities that composes nuclear fleet. The increase computing capacities use neutron data fast predictors...
The CNRS has been involved in molten salt reactors since 1997. Starting from the Molten Salt Breeder Reactor project of Oak-Ridge, an innovative concept called Fast or MSFR proposed, resulting extensive parametric studies which various core arrangements, reprocessing performances and compositions were investigated to adapt reactor framework deployment a thorium based fleet on worldwide scale. primary feature is removal graphite moderator (graphite-free core), breeder with fast neutron...
This paper present the measurements of VENUS-F kinetic parameters using Rossi-Alpha methods. The reactor is a zero-power based in Mol, Belgium at SCK-CEN [1]: its fuel made metallic enriched uranium with pure lead order to simulate behavior fast reactor. can be operated sub-critical state when it coupled GENEPI-3C neutron source [2]. At beginning 2014, measurement campaign was performed critical estimate In this paper, two are analyzed different powers (approximately 2W and 30W) 7 fission...
Gamma production cross sections have been obtained for 81 transitions in 232 Th from (n,n’γ), 11 231 (n,2nγ) and 7 230 (n,3nγ) reactions using prompt gamma spectroscopy. Incident neutron energies were determined the time-of-flight technique. Sources of uncertainty examined their correlations computed. Total on ranges 4 to 20%. Obtained are agreement with prior experiments, but not well reproduced by TALYS 1.8 reaction code default parameters. During analysis, discrepancies between our...
The GUINEVERE project was launched in 2006, within the 6th Euratom Framework Program IP-EUROTRANS, order to study feasibility of transmutation Accelerator Driven subcritical Systems (ADS). This zero-power facility hosted at SCK·CEN site Mol (Belgium) couples fast lead reactor VENUS-F with an external neutron source provided by interaction deuterons delivered GENEPI-3C accelerator and a tritiated target located core center. In test on-line subcriticality monitoring techniques, reactivity all...
Accelerator-Driven Systems (ADS) could be employed to incinerate minor actinides and so partly contribute answer the problem of nuclear waste management. An ADS consists coupling a subcritical fast reactor particle accelerator via heavy material spallation target. The on-line reactivity monitoring such an is serious issue regarding its safety. In order study methodology this monitoring, zero-power experimentswere undertaken at GUINEVERE facility within framework FP6-IP-EUROTRANS programme....
Most fuel cycle simulation tools are based either on fixed recipes or assembly calculations for reactor modeling. Due to the high number of and extensive computational power requirements, full-core computations often seen as not viable this purpose. However, leads additional hypotheses modeling biases, thus limiting realism resulting cycle. For several applications, current method is sufficient, but precise discharged composition may require further refinements. CLASS ( C ore L ibrary A...
This paper present basic nuclear reactor physics that may help to understand next challenges industry have face in the future. The ones considered this work are waste production and natural resources consumption. shows linked by plutonium status could be as principal or a valuable material should saved for future transition breeder reactors instance Sodium-cooled Fast Reactors (SFRs). kind of does not rely on resource supply, it produces its own fissile material, plutonium-239, after neutron...
