Management of Radioactive Substances During Life-Cycle of Nuclear Energy

Radioactive by-products that result from the nuclear energy process include both materials from the nuclear fuel cycle and equipment used in the transformation of nuclear energy that becomes contaminated through continued exposure to radioactive fuel, impurity elements, and cooling media. Although these waste products, especially high-level radioactive wastes, are moderately to very hazardous, they are […]

Pathways to a Sustainable Energy Future: A Case Study

Following from the advantages of the portfolio approach, as discussed above, most projections of primary energy production for the twenty-first century recognize that the three endpoint technologies of Table 15-1 will all play a role in meeting demand, although the relative contribution of each resource varies from projection to projection. In this section we consider […]

Prospects for Geological Sequestration

Sequestration research up to the present time indicates that between subterranean and sea-bottom options, there is adequate capacity for sequestration of all foreseeable CO2 emissions from fossil fuel production, provided that we invest sufficiently in facilities to separate and sequester it. The risk associated with sequestration, both from leakage under ordinary conditions and from seismic […]

Definition of Solar Geometric Terms and Calculation of Sun’s Position by Time of Day

In the preceding section, we considered sunlight traveling through the atmosphere, without necessarily considering the effect of the sun’s position in the sky on the amount of energy available. In this section, we introduce several other terms used to discuss solar geometry, and then chart the sun’s position in the sky as a function of […]
