Abstract

The Modified Source Multiplication method is used to determine an unknown reactivity level of a reactor from a known one if one has access to the detector counting for both levels when the reactor is fed by a constant neutron source like an Am-Be source. When available, an accelerator driven source, in continuous mode, can be useful as its intensity can be tunable and then adapted to the experimental conditions. However, in that case, the MSM technique must be extended to account for an external source whose intensity, energy and angular distributions can vary from one measurement to another. In this paper, this Modified Multi-Source Multiplication (MMSM) method is applied to measurements done during the FREYA project in the GUINEVERE facility, operated with the GENEPI-3C accelerator providing a mixture of (D,T) and (D,D) neutrons. The monitoring of these sources through the detection of the associated charged particles allows the calculation of the MMSM factors and the estimate of the reactivity values. The results are compared in different configurations with the reactivity obtained with an Am-Be source or in dynamic measurements performed with GENEPI-3C. Their excellent agreement shows the possibility of using such accelerator-based neutron sources for MSM measurements when they are correctly monitored. This is of great interest for deep sub-critical level characterization for which detector count rates per source neutrons might be low.

Abstract

Three sub-critical (SC) core configurations were investigated in the VENUS-F zero power reactor coupled with the GENEPI-3C accelerator. The SC10 and SC12 were a mock-up of a MYRRHA start-up core and SC11 represented a more complex MYRRHA core loaded with various types of in-pile-sections. The sub-criticality of 11 variants of these VENUS-F cores was changed in several steps from -6$ down to -30$ using the safety and control rods. Their sub-criticalities were determined with the Source Jerk Integral (SJI) method using 11 fission chambers located all over the reactor. For the data analysis, the 8-group delayed neutron parameters from the JEFF-3.1.2 evaluated nuclear data library were used. Reliability and reproducibility of the experimental results were tested by repeating the measurements, swapping the detectors and varying the accelerator beam intensity, thus changing the detector count rates and verifying the validity of the dead time corrections. The obtained results are compared with MCNP calculations.

Abstract

VENUS-F is a fast zero power reactor with 30 wt% U fuel and Pb/Bi as a coolant simulator. Depending on the experimental configuration, various neutron spectra (fast, epithermal, and thermal islands) are present. This paper gives a review of the nuclear instrumentation that is applied for reactor control and in a large variety of physics experiments. Activation foils and fission chambers are used to measure spatial neutron flux profiles, spectrum indices, reactivity effects (with positive period and compensation method or the MSM method) and kinetic parameters (with the Rossi-alpha method). Fission chamber calibrations are performed in the standard irradiation fields of the BR1 reactor (prompt fission neutron spectrum and Maxwellian thermal neutron spectrum).

Abstract

Accelerator-Driven Systems (ADS) could be employed to incinerate minor actinides and so partly contribute to answer the problem of nuclear waste management. An ADS consists of the coupling of a subcritical fast reactor to a particle accelerator via a heavy material spallation target. The on-line reactivity monitoring of such an ADS is a serious issue regarding its safety. In order to study the methodology of this monitoring, zero-power experimentswere undertaken at the GUINEVERE facility within the framework of the FP6-IP-EUROTRANS programme. Such experiments have been under completion within the FREYA FP7 project. The GUINEVERE facility is hosted at the SCK-CEN site in Mol (Belgium). It couples the VENUS-F subcritical fast core with the GENEPI-3C accelerator. The latter delivers a beam of deuterons, which are converted into 14-MeV neutrons via fusion reactions on a tritiated target. This paper presents one of the investigated methods for ADS on-line reactivity monitoring which has to be validated in the program of the FREYA project. It describes the results obtained when Pulsed Neutron Source experiments are analysed using the so called Area Method, in order to estimate the reactivity of a few sub-critical configurations of the VENUS-F reactor, around keff= 0.96. First the GUINEVERE facility is described. Then, following general considerations on the Area method, the results of its application to the neutron population time decrease spectra measured after a pulse by several fission chambers spread out over the whole reactor are discussed. Finally the reactivity values extracted are compared to the static reactivity values obtained using the Modified Source Multiplication (MSM) method., Comment: International Workshop on Technology and Components of Accelerator Driven Systems (TCADS) OECD Nuclear Energy Agency, Nantes : France (2013)

12. Deep Subcriticality Determination Using the Source Jerk Integral Method in the SALMON Program

Author

Kochetkov, A., Krása, A., Messaoudi, N., Vittiglio, G., Wagemans, J., Bailly, A., Billebaud, A., Chabod, S., Lecolley, F.-R., Lecouey, J.-L., Lehaut, G., and Marie, N.

Abstract

AbstractThe Source Jerk Integral (SJI) method has been extensively used to determine the subcriticality in VENUS-F zero-power experiments since 2012. The obtained resultswere in the range from −5 $ to about −20 $ and concerned the subcriticalities of accelerator-driven system MYRRHA mockup cores. Within the SALMON program, which is dedicated to the safe loading procedure of pressurized power reactors, five subcritical core configurations were assembled and studied in the VENUS-F reactor in 2019. These cores simulated the loading process in inverse mode: from more reactive to deep subcritical. The subcriticality of five variants of the SC11 VENUS-F core was changed in steps from −20 $ to about −100 $ by replacing the fuel assemblies with lead reflector assemblies. The subcriticality levels were determined with the pulsed neutron source (PNS) and SJI methods. The GENEPI-3C deuterium accelerator coupled with VENUS-F was used as an external neutron source. The results of the measurements obtained with the SJI method are presented in this paper. Time-dependent Monte Carlo calculations were performed to simulate the SJI experiments and to determine spatial-energy correction factors. Static Monte Carlo simulations were performed to calculate neutron spectra and reactivity. The results of the measurements (both SJI and PNS) are compared with the static MCNP calculations.

Abstract

The MSM method is an experimental technique for determination of reactivity of a sub-critical reactor. It consists of one dynamic measurement followed by two static measurements, which use an extraneous neutron source. For the data analysis, the core averaged kinetic parameters need to be calculated as well as a spatially-dependent correction factor that corrects for the point kinetics approximation. In order to test the range for which the method is valid and to demonstrate the reliability of the correction factor calculations in a fast reactor, a dedicated experimental campaign was performed in the fast lead-bismuth VENUS-F reactor. The reactivity of a dozen of sub-critical configurations was measured with the MSM method using ten 235U fission chambers. The detectors were located at various distances from the active zone and from the extraneous neutron source, leading to a large range of values of a correction factor (calculated with the Monte Carlo MCNP5 code) used in the data analysis.

Abstract

During the GUINEVERE FP6 European project (2006-2011), the zero-power VENUS water-moderated reactor was modified into VENUS-F, a mockup of lead cooled fast spectrum system with solid components that can be operated in both critical and subcritical mode. The Fast Reactor Experiments for hybrid Applications (FREYA) FP7 project was launched in 2011 to support the designs of the MYRRHA Accelerator Driven System (ADS) and the ALFRED Lead Fast Reactor (LFR). Three VENUS-F critical core configurations, simulating the complex MYRRHA core design and one configuration devoted to the LFR ALFRED core conditions were investigated in 2015. The MYRRHA related cores simulated step by step design peculiarities like the BeO reflector and in pile sections. For all of these cores the fuel assemblies were of a simple design consisting of 30 % enriched metallic uranium, lead rodlets to simulate the coolant and Al2O3 rodlets to simulate the oxide fuel. Fission rate ratios of minor actinides such as Np-237, Am-241 as well as Pu-239, Pu-240, Pu-242 and U-238 to U-235 were measured in these VENUS-F critical assemblies with small fission chambers in specially designed locations, to determine the spectral indices in the different neutron spectrum conditions. The measurements have been analyzed using advanced computational tools including deterministic and stochastic codes and different nuclear data sets like JEFF-3.1, JEFF-3.2, ENDF/B7.1, ENDF/B6.8, JENDL-4.0 and TENDL-2014. The analysis of the C/E discrepancies will help to improve the nuclear data in the specific energy region of fast neutron reactor spectra.

Abstract

International audience; As a prolongation of the FP-6 GUINEVERE (Generation of Uninterrupted Intense NEutron pulses at the lead VEnus REactor)project at the VENUS-F facility at SCK• CEN, the FP-7 FREYA (Fast Reactor Experiments for hYbrid Applications) project was launched in2011. The FREYA project aims at validating the methodology for subcriticality monitoring of a subcritical core as proposed in the MUSEexperiments conclusions. This is needed for the reactivity monitoring of a powerful ADS (Accelerator Driven System) like MYRRHA.Experiments are also needed for sub-critical and critical ADS and LFR (Lead Fast Reactor) core characterisation for benchmarking andlicensing purposes. Several levels of sub-criticality of the first subcritical core were measured applying the integral Source Jerk methodand compared to the reference results obtained with the MSM (Modified Source Multiplication) method.

Abstract

International audience; Experiments with a subcritical core and an external pulsed neutron source (PNS) have been performed at the VENUS-F reactor of theSCK-CEN during the year 2012 within the frame of the FREYA project of the 7th European Framework Programme. Different reactivity levels,obtained by varying the position of the control rods and the safety rods, have been investigated, with values of kef f ranging between 0.9and 0.96. The area-ratio and the prompt decay constant techniques are well-known techniques to determine the reactivity of the systemfrom the results of PNS experiments. However, both techniques are based on the point kinetics model and hence they are affected by thespatial and energy effects present in real systems, which will cause them to produce biased values of the reactivity. In this work, we applya methodology based on Monte Carlo simulations to assess the spatial and energy effects present in the VENUS-F core and to determinerelationships between the reactivity and the measured parameters (area-ratio and prompt decay constant) that take into account these effects and allow the application of the reactivity determination techniques to obtain accurate reactivity values beyond the limits of the point kinetics model. The results of the validation of this methodology against the experimental results obtained in the VENUS-F reactor will also be discussed.

Abstract

Proc. CD Series IAEA-13-CN-173 ISBN 9789201504104; International audience; GUINEVERE, Generator-of-Uninterrupted-Intense-NEutrons-at-the-lead-VEnus-REactor, is a project of the Domain 2 of the FP6 EUROTRANS Integrated Project devoted to Accelerator Driven System (ADS) feasibility studies. Domain 2, ECATS, is related to specific Experiments for Coupling an Accelerator, a Target and a Subcritical core. GUINEVERE will investigate on-line reactivity monitoring, sub-criticality determination and operational procedures in an ADS. The project consists in coupling a modified VENUS facility at the SCK-CEN site in Mol (Belgium) to an upgraded GENEPI neutron source. SCK-CEN is transforming the water moderated VENUS reactor into a fast lead core facility, the fuel and lead rodlets being provided by CEA. The GEnerator-of-NEutrons-Pulsed-and-Intense is an electrostatic accelerator generating 14 MeV neutrons by bombarding a high intensity deuteron beam on a tritium target located in the reactor core. CNRS is designing and building a new accelerator, GENEPI-3C, to meet the new requirements of the experimental program: it will be capable of delivering alternatively 1 μs long deuteron pulses with adjustable repetition rate, as well as continuous beam with programmable interruptions. This paper will describe the design and commissioning of the GENEPI accelerator

Abstract

International audience; The GUINEVERE project is running since 2007 and is part of the EUROTRANS Integrated Project of the 6th EURATOM Framework Programme. It consists first in the construction of a lead fast ADS mock-up at SCK-CEN Mol (Belgium) for the purpose of ADS subcriticality monitoring experiments, and beyond in support to the design of a Transmutation Experimental Facility (MYRRHA/FASTEF). To do so the VENUS reactor (SCK-CEN) will be coupled with a new GENEPI neutron source under construction by CNRS (France). To accommodate this new source (a 250 keV deuteron accelerator) in a vertical coupling configuration, the VENUS building is being heightened. In parallel the reactor core is being modified to be loaded with fuel assemblies made of enriched Uranium and solid Lead moderator pins, and hold radial and axial Lead reflectors. A new safety and control rod system is also under development. The new GENEPI-3C neutron source is designed to be operated in pulsed mode but also in continuous mode to investigate the current-to-flux reactivity indicator in representative conditions of a powerful ADS. In this latter mode it will be also possible to make short beam interruptions at a fixed frequency to have access to the neutron population decrease as a function of time. The vertical beam line will have the distinctive feature to be retractile, allowing target changing or complete removal (for critical configuration for example). The accelerator will be first completely assembled at LPSC Grenoble for beam characterization before to be transferred in Mol. We will present in this paper the status of this experimental facility assembling, and foreseen experimental programmes in the framework of fast transmutation system studies.

Abstract

paper 9414; International audience; The GUINEVERE project is part of the EUROTRANS Integrated Project of the 6th EURATOM Framework Programme. It is mainly devoted to ADS on-line reactivity monitoring validation, sub-criticality determination and operational procedures (loading, start-up, shut-down, ...) as a follow-up of the MUSE experiments. The project consists in coupling a fast lead core, set-up in the VENUS reactor at SCK*CEN Mol (B), with a GENEPI neutron source under construction by CNRS. To accommodate the accelerator in a vertical coupling configuration, the VENUS building is being heightened. The fast core will be loaded with enriched Uranium and will be moderated and reflected with solid lead (zero power experiment). For the purpose of the experimental programme, the neutron source has to be operated not only in pulsed mode but also in continuous mode to investigate the current-to-flux reactivity indicator in representative conditions of a powerful ADS. In this latter mode it is also required to make short beam interruptions to have access to the neutron population decrease as a function of time: from this spectrum it will be possible to apply different analysis techniques such as "prompt decay" fitting techniques and "source jerk" techniques. Beam interruptions will be repeated at a programmable frequency to improve time spectra statistics. Different sub-criticality levels (keff=0.99, 0.97, 0.95, ...) will be investigated in order to obtain a full set of data points for the final overall validation of the methodology. This paper describes the status of the experimental facility assembling, and the foreseen experimental programme to be started.

Abstract

Proc. on CD Rom log315; International audience; The GUINEVERE project is an international project in the framework of IP-EUROTRANS, the FP6 program which aims at addressing the main issues for ADS development in the framework of partitioning and transmutation for nuclear waste volume and radiotoxicity reduction. The GUINEVERE project is carried out in the context of domain 2 of IP-EUROTRANS, ECATS, devoted to specific experiments for the coupling of an accelerator, a target and a subcritical core. These experiments should provide an answer to the questions of online reactivity monitoring, sub-criticality determination and operational procedures (loading, start-up, shutdown, …) in an ADS by 2009-2010. The project has the objective to couple a fast lead core, within the VENUS building operated by the SCK•CEN, with a neutron generator able to work in three different modes: pulsed, continuous and continuous with beam interruptions at the millisecond scale. In order to achieve this goal, the VENUS facility has to be adapted and a modified GENEPI-3C accelerator has to be designed and constructed. The paper describes the main modifications to the reactor core and facility and to the accelerator, which will be executed during the years 2008 and 2009, and the experimental programme which will start in 2009.
