This report describes a novel approach developed at the Oak Ridge National Laboratory
(ORNL) for the estimation of the uncertainty in the prediction of the neutron multiplication factor
for spent nuclear fuel. This technique focuses on burnup credit, where credit is taken in criticality
safety analysis for the reduced reactivity of fuel irradiated in and discharged from a reactor.
Validation methods for burnup credit have attempted to separate the uncertainty associated with
The objective of this calculation is to provide the uncertainty term for fission product and minor actinides which contributes to the determination of the critical limit for burnup credit calculations. The scope of this calculation covers PWR and BWR spent nuclear fuel. This activity supports the Criticality Department's validation of burnup credit. The intended use of these results is in future Criticality Department calculations and analyses.
Press release by STUK stating that it will be reviewing Posiva Oy's license application for constructing a repository for disposal of spent nuclear fuel.
Posiva webpage discussing selecting the site for final disposal of spent fuel.
Presentation by Posiva Oy at The Stockholm Talks on October 2, 2013 on the status of the Finnish nuclear waste management program.
The Finnish nuclear regulator needs another six months to review Posiva's application to build a waste encapsulation plant and a final repository at Olkiluoto.
