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.
The government of the Republic of Korea, as a contracting party to the Joint<br/>Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive<br/>Waste Management (hereinafter referred to as “Joint Convention”) which entered into<br/>force on June 18, 2001, and deposited the ratification of on September 16, 2002,<br/>described the state of implementing the contracting party’s obligations in the Third<br/>National Report, pursuant to Article 32 (Reporting) of the Joint Convention.<br/>This National Report was prepared in accordance wi
The Korean government has maintained a consistent national policy for stable energy supply by fostering nuclear power industries under the insufficient energy resources in the country. Nuclear power reached approximately 40 % of total domestic electricity generation. Since the commencement of the first commercial operation of Kori Unit 1 in April 1978, 20 units of NPPs are commercially operating as of October 2005. Four units out of the 20 operating NPPs are Pressurized Heavy Water Reactors (PHWRs) at Wolsong.
