Question

A possible way to evaluate the extent of uranium resources is to build a probabilistic model that includes both known resources and possible unconventional sources of uranium and their relative cost of extraction, and then to project the cost of uranium as a function of the number of nuclear power plants.

 

 

Answer 1

Nuclear power plants generate steam by heating water. The steam is utilized to create energy by spinning large turbines. Atoms are broken apart to produce smaller atoms in nuclear fission, which releases energy. Fission takes occur within a nuclear power plant's reactor.

 

Light-water reactor uses regular water instead of heavy water as a neutron moderator and coolant and uses a solid form of fissile materials as fuel.

 

Uranium is a globally traded commodity with a number of dependable suppliers. Furthermore, nuclear reactors are costly equipment that utilizes easily obtainable fuel; there has been little worry in the United States about “Uranium Energy Independence.” Indeed, 80% percent of uranium has been imported without issue during the last decade.

 

The following research uses a 200 metric tons natural uranium demand per full-power gigawatt year as a baseline. The kind of reactor, enrichment plant tails specification, operator fuel management methods, plant capacity factor, and thermodynamic efficiency attained all influence yearly values. Ore demand is less unpredictable than uranium supply since it is strongly connected to nuclear-generating capability.

 

The major input is Deffeye’s uranium reserve model as a function of ore grade, which he developed in the late 1970s. The supply of uranium ores of practical interest rises by roughly 2% for every 1% reduction in average grade mined down to a grade of 1000 ppm. The research applied previously developed models to specific mined uranium resources to a global ensemble of uranium deposits. If one is willing to mine lower-grade uranium deposits, the uranium resources grow considerably.

 

The recovery of uranium as a co-product or by-product of other mining activities is an important aspect not taken into consideration in predicting uranium resources. Phosphate deposits are the most important category here. Finally, numerous scholars have pointed out that Deffeye’s evaluation was conducted before the discovery of rich ore resources in Canada with grades above 3%. This might indicate that the anticipated cost increase based on his findings will be postponed for a while.

 

In addition to uranium supply versus ore grade elasticity, the model contained three other features:

 

A steep learning curve: In all sectors, there is a learning curve in which production costs decrease as the industry gains experience.

 

Scale economies: Mining operations are subject to traditional economies of scale.

 

Probabilistic evaluation: Extrapolation into an ill-defined future is not a deterministic endeavor since the exact solution cannot be known. As a result, a probabilistic method was used in these models, following the example of Starr and Braun of Electric Power Research Institute in a similar effort in 1980.

 

Based on a study of published data and research, as well as current cost/resource modeling, there is a high degree of confidence that natural uranium will be available at affordable prices for a long time.
