Reliability of Risk Assessments for Geological Disposal of Nuclear Waste

FOR GEOLOGICAL DISPOSAL OF NUCLEAR WASTE Some aspects regarding the reliability of risk assessments for geological disposal of nuclear waste are investigated. The input for the study is given by the opinions of some interviewed Dutch experts and existing literature. The Dutch risk assessment PROSA is used as an example, but the conclusions are seen to be valid more generally. In the PROSA study...

Robotic Inspection of Nuclear Waste Storage Facilities

Introduction Safe disposal of nuclear waste is a difficult problem. Long-term plans are to house nuclear waste permanently in underground facilities. In the near-term however, nuclear waste is stored in temporary storage facilities at various sites around the country. Federal and state regulations require periodic inspection of these storage facilities to insure storage vessel integrity and ver...

Solid wastes from nuclear power production.

Radioactivity in nuclear power effluents is negligible compared to that in retained wastes to be disposed of as solids. Two basic waste categories are those for which shallow disposal is accepted and those for which more extreme isolation is desired. The latter includes "high level" wastes and others contaminated with radionuclides with the unusual combined properties of long radioactive half-l...

Partitioning-transmutation Technology: a Potential Future Nuclear Waste Management Option

Partitioning-transmutation technology (PT) will produce radioactive wastes of different physical and chemical properties and in different amounts from those generated in the current nuclear fuel cycle. To assess quantitatively the effects of PT on waste disposal, we first analyzed the amounts of the PT wastes, assumed conditioning for each type of the waste, and then made an attempt to estimate...

Nuclear Power and Resource Efficiency—A Proposal for a Revised Primary Energy Factor

Measuring resource efficiency can be achieved using different methods, of which primary energy demand is commonly used. The primary energy factor (PEF) is a figure describing how much energy from primary resources is being used per unit of energy delivered. The PEF for nuclear power is typically 3, which refers to thermal energy released from fission in relation to electricity generated. Fuel l...
