N-Reactor Spent Nuclear Fuel Criticality Calculations
N-Reactor Spent Nuclear Fuel Criticality Calculations
The purpose of this calculation is to characterize the criticality safety aspects of N-Reactor fuel stored in a Department of Energy spent nuclear fuel (DOE-SNF) canister that contains four Multi-Canister Overpacks (MCO's). These calculations will be done to support the analysis that will be done to demonstrate concept viability related to pre-emplacement storage and use in the Monitored Geologic Repository (MGR) environment for the pre-closure time frame.
Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, National Report for Uruguay
Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, National Report for Uruguay
There are no nuclear power stations and no nuclear fuel cycle activities in Uruguay. There are only disused radioactive sources from medical and industrial practices and there is a disused conditioned neutron Pu-239 source with 185 TBq, waiting for its reshipment to the United States. This material is stored in the building in which it was an old research reactor. The application of the Convention is limited to radioactive waste arising from the medical, industrial and research applications of radioisotopes.
