Meeting: uncertainty propagations in the nuclear fuel cycle
Time: 2013-04-24 - 2013-04-25
Place: Uppsala University
Uppsala University together with Vattenfall are hosting a meeting, where some of the different stakeholders and experts in reactor simulations and reactor safety are invited. The meeting has an emphasis on the Swedish nuclear sector.
The purpose of the meeting is to:
- identify how uncertainty propagations in the nuclear fuel cycle and reactor safety calculations are done today. How could it be improved?
- discuss if the requirements for uncertainty propagations are to be changed the future? What are the potential benefits?
- find out how the Total Monte Carlo methodology can be tested and possibly be implemented within existing commercial code packages.
- establish new relations between the nuclear engineering industry and academia within this field.
- explore how new methodologies can help to improve quality assurance issues.
This is the second meeting organized to adress these issues. The first was organized by CCFE: Workshop on Nuclear Data and Uncertainty Quantification – January 2012, Culham.
13:15 Stephan Pomp: Welcome. Presentation of participants.
14:00 Arjan Koning, NRG: "Nuclear data uncertainty propagation using a Total Monte Carlo approach"
14:45 Ewa Kurcyusz-Ohlofsson: "Vattenfall’s perspective on uncertainty analysis"
15:45 Jan - Christophe Sublet: "Reaction rate uncertainty quantifications and propagations"
16:15 Oliver Buss, Areva: "NUDUNA, Nuclear Data Uncertainty Analysis"
16:45 Dimitri Rochman: "Perturbation vs. Total Monte Carlo"
17:45 Closing remarks: Henrik Sjöstrand
19:30 Dinner at Villa Romana
09:00 Henrik Sjöstrand: "Uncertainty propagation work at Uppsala university"
09:30 Discussion: how to integrate TMC or other uncertainty methodologies into existing codes. Starts with a presentation from Maria Pusa VTT: "CASMO and SERPENT"
13:00 Closing remarks
Oddbjörn Sandervåg - SSM - "Computational Nuclear Power Safety and Uncertainties"
Peter Hessling - SP - "Methods for Modeling uncertainty - Model uncertainty" (not presented during the meeting)
Discussions: examples of planned topics
Computational requirements and limitations
Expected requirements from the safety authorities
What are the requirements on uncertainty estimates within the industry?
Representatives from the following institutions will participate:
Vattenfall nuclear fuel, Studsvik Scandpower, AREVA, SSM, SKB, VTT, Forsmark, CCFE, NRG, SP, Uppsala University
The meeting will be held at the Uppsala University, Ångström laboratory, Lägerhyddsvägen 1, Uppsala. Room 13167 (house 1, third floor, as far south as you can come, i.e. not on the same side as the reception, use the south entrance). Map.
