Nuclear physics model codes Nuclear physics experiments End-user applications Nuclear data evaluation Co-variances and uncertainty quantification

 Main goal: perform accurate measurements of

cross-sections in neutron-induced reactions.

 To be used at neutron research facility NFS

(Neutrons For Science) at GANIL (Caen, France).

 Development and upgrade of the detection setup

“Medley”, for different projects:

 Commissioning of the NFS neutron beam.  LIONS (Light ION production Studies).

 Reactor aging

 FISHES (FISsion vs Hydrogen Elastic Scattering).

 Reactor and criticality physics

The ongoing development of PPACs (Parallel Plate Avalanche Counters) and of the general setup led to different publications and student projects:

 D. Tarrío et al., “Characterization of PPACs’ time resolution for fission

studies”. Presented at the Int. Conf. On Nuclear Data 2019, Beijing (China). Submitted to EPJ Web of Conf. (2019).

 L. Lehtilä, “Implementation and characterization of Silicon detectors for

studies on neutron-induced nuclear reactions”, M.Sc. Thesis, 2019.

 K. Nakano, “Measurement of first Townsend coefficient of C3F8 for

characterization of PPAC”, internal report (2018). Visiting Ph.D. student from Kyushu University (Japan).

 Several projects for undergraduate students.

Development of the Medley setup for NFS

The renovated Medley chamber will be sent to NFS by the end of 2019 A PPAC detector

Medley -> NFS@GANIL

Stephan Pomp

Goal: Use the Medley setup at the Neutrons For Science (NFS) facility at GANIL (Caen, France): Perform studies of the fission process and light-ion production (dosimetry, gas production, etc.). Status: After many years of delay NFS finally starts commissioning during 2020. Medley has been dismantled, partly adjusted and renovated for NFS, cleaned, etc., and is ready for shipping. Next: Medley will be shipped to NFS end of Nov. Installation and first use in the commissioning is planned for Spring 2020.

Main compontents of Medley: ready to be packed for shipping

Evaluation and Uncertainty Quantification

Henrik Sjöstrand

• Focus 2019, model defects and unrecognized systematic

uncertainties. – More information by Henrik Sjöstrand, Machine learning regression for reactor-relevant nuclear data tomorrow at 11.05 – Continuation of MÅBiL funded research

• Code system available under GitHub

(http://www.nucleardata.com/) (open access)

• Methods applied to iron with relevance for reactor aging

and for criticality analysis.

• Results presented at ND 2019 – Beijing and as

contributions to NEA – WPEC

Future developments of GET

Peter Andersson, Vikram Rathore, Lorenzo Solis

• Higher spatial resolution

(hundreds of microns) is envisioned for next generation GET system.

• Improved data collection rate can

be achieved by – Using a multiple channel segmented detector – Optimized collimator geometry – Reduced cooling time of fuel prior to PIE

• A new detector concept has been

developed, with multiple detector channels, for faster interrogation, which in turn allows for higher resolution.

Nuclear Safeguards – Research

Sophie Grape, Erik Branger, Zsolt Elter, Vaibhav Mishra, Ane Håkansson, Li Pöder Balkeståhl

• Erik Branger defended his thesis October 12, 2018 and

currently is postdoc in the research group.

• Viabhav Mishra is a new Ph.D. student within
• safeguards. His research focus lies on verification of

spent fuel prior to encapsulation and novel technical safeguards approaches for Gen IV.

• The research has during the last year addressed

verification of non-regular fuels and the use of quivers.

• The work with machine learning techniques

continues now in collaboration with SCK•CEN in Belgium.

• We have, within a Horizon2020-project, offered the so-called course in

safeguards (Feb 4-8 in Mol, November 11-15 in Jülich)

• Collaborators are: SCK•CEN, FZJ and JRC Ispra.
• In addition to the course, four workshops are offered.
