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.
This is the fourth National Report by Australia.1 The 2008 National Report and Australia’s presentation to the Third Review Meeting in 2009 highlighted the following major issues:
• progress on national uniformity;
• progress with development of a national waste classification scheme;
• radioactive waste management policy – achievements, consultation, strategy;
• spent fuel management and management of reprocessing waste;
• decommissioning;
• uranium mining waste management; and
• recruitment and skills management.
This is the third National Report by Australia1. The 2005 National Report and Australia’s presentation to the Second Review Meeting in 2006 highlighted issues as to how each of the nine Australian jurisdictions within Australia’s federal system are complying with the Joint Convention. A challenge identified for Australia in the Rapporteur’s Report for Country Group 3 was “ensuring a coherent approach to regulations and waste management practice in view of the complex nature of national and regional legislation”.
The responsibility for the governance of Australia is shared by the Australian government and the governments of the six states and two self governing territories. Responsibility for radiation health and safety in each State and Territory rests with the respective State/Territory government, unless the activity is carried out by an Australian government agency or a contractor to a Australian government agency; in those cases the activity is regulated by the Australian government.
The responsibility for the governance of Australia is shared by Australia's federal government (also known as the Commonwealth government) and the governments of the six states and two self governing territories. Responsibility for radiation health and safety in each State and Territory rests with the respective State/Territory government, unless the activity is carried out by a Commonwealth agency or a contractor to a Commonwealth agency; in those cases the activity is regulated by the Federal government (Commonwealth government of Australia).
