The capability to determine the age (time since irradiation) of spent fuel can be useful for verification and safeguards. While the age of spent fuel can be determined based on measurements of short-lived fission products, these measurements are not routinely done nor generally reported. As an alternative, age can also be determined if the uranium (U) and plutonium (Pu) isotopic values are available. Uranium isotopics are not strongly affected by fuel temperature, and bumup is determined from the 235U and 236U isotopic values. Age is calculated after estimating the 241Pu at the end of irradiation while accounting for the fuel temperature, which is determined from 239Pu or 24°Pu. Burnup and age determinations are calibrated to reactor models that provide uranium and plutonium isotopics over the range of fuel irradiation. The reactor model must contain sufficient fidelity on details of the reactor type, fuel burnup, irradiation history, initial fuel enrichment and fuel temperature to obtain accurate isotopic calculations. If the latter four are unknown, they can be derived from the uranium and plutonium isotopics. Fuel temperature has a significant affect on the production of plutonium isotopics; therefore, one group cross section reactor models, such as ORIGEN, cannot be used for these calculations. Multi-group cross section set codes, such as Oak Ridge National Laboratory's TRITON code, must be used.

This publication is the result of an IAEA technical meeting and reports on Member States' capabilities in modelling, predicting and improving their understanding of the behaviour of nuclear fuel under accident conditions. The main results and outcomes of a coordinated research project (CRP) on this topic are also presented.

This publication is a revision by amendment of IAEA Safety Standards Series No. SSG-15 and provides recommendations and guidance on the storage of spent nuclear fuel. It covers all types of storage facility and all types of spent fuel from nuclear power plants and research reactors. It takes into consideration the longer storage periods beyond the original design lifetime of the storage facility that have become necessary owing to delays in the development of disposal facilities and the reduction in reprocessing activities. It also considers developments associated with nuclear fuel, such as higher enrichment, mixed oxide fuels and higher burnup. Guidance is provided on all stages in the lifetime of a spent fuel storage facility, from planning through siting and design to operation and decommissioning. The revision was undertaken by amending, adding and/or deleting specific paragraphs addressing recommendations and findings from studying the accident at the Fukushima Daiichi nuclear power plant in Japan.

This book contains papers from a NATO-sponsored workshop in Almaty in September 2005, which discussed safety-related issues of storing spent nuclear fuel. Fifteen papers cover aluminum-clad fuel discharged from research reactors worldwide, while five papers examine stainless steel-clad fuel from fast reactors, and two Zircaloy-clad fuel from commercial light-water reactors.

With an increase of global security concerns over potential terrorist acts, the threat of WMDs, and increasing political issues with nations seeking nuclear capability, the need to track, detect, and safeguard nuclear material globally has never been greater. Nuclear Safeguards, Security and Nonproliferation is a comprehensive reference that covers cutting-edge technologies used to trace, track, and safeguard nuclear material. It is a contributed volume with sections contributed by scientists from leading institutions such as Los Alamos National Labs, Sandia National Labs, Pacific Northwest Nuclear Labs, and Texas A&M University, and the Monterey Institute of International Studies. The book is divided into 3 sections and includes 30 chapters on such topics as - the security of nuclear facilities and material, the illicit trafficking of nuclear materials, improvised nuclear devices, how to prevent nuclear terrorism. International case studies of security at nuclear facilities and illegal nuclear trade activities provide specific examples of the complex issues surrounding the technology and policy for nuclear material protection, control and accountability. Specific cases include analysis of the timely issues in the nuclear programs of countries such as North Korea, Iran, and Kazakstan among others. Nuclear Security is a must-have volume for the dozens of private and public organizations involved in driving Homeland Security, domestic, and international policy issues relating to nuclear material security, non-proliferation, and nuclear transparency. - Written by some of the world's top scientists including members of the Nuclear Division of Los Alamos National Labs (U.S.) - A timely discussion of current international nuclear security issues includes case studies on Iraq, Iran and North Korea - Book takes a global perspective on nuclear security and non-proliferation detailing the little-known real-world technologies used to secure, detect and track nuclear material
