As a domain expert in nuclear energy and resource management, I have a deep understanding of the dynamics and projections related to uranium as a fuel source for nuclear power. Uranium, a naturally occurring radioactive element, is the primary fuel used in nuclear reactors to generate electricity. The longevity of uranium as a resource depends on various factors, including the rate of consumption, technological advancements in uranium extraction and utilization, and the discovery of new reserves.

The Nuclear Energy Agency (NEA) has conducted extensive research and estimations on the planet's economically accessible uranium resources. According to their assessments, if the current consumption rates are maintained, the world's known uranium resources could sustain nuclear reactors for more than 200 years. This estimation takes into account the existing identified resources that are economically viable to extract with today's technology and market conditions.

However, it's important to note that this projection is subject to change due to several variables. The first is the rate of uranium consumption, which can be influenced by the growth of the nuclear power industry, technological advancements that increase the efficiency of uranium use, and the development of alternative energy sources. For instance, advancements in breeder reactors, which can generate more fissile material than they consume, could significantly extend the lifespan of uranium resources.

Secondly, the discovery of new uranium deposits can alter the availability of this resource. Geological surveys and explorations are continuously conducted worldwide, and with improvements in exploration technology, it is possible to identify new reserves that were previously inaccessible or unknown.

Thirdly, the recycling of spent nuclear fuel through reprocessing can recover a significant portion of the uranium and plutonium, effectively extending the life of uranium resources. This process, although complex and costly, is an area of ongoing research and development.

Lastly, the global political and economic landscape can impact the availability and distribution of uranium. International cooperation, trade agreements, and geopolitical tensions can all influence the supply chain and the accessibility of uranium resources.

In conclusion, while the NEA's estimation provides a solid foundation for understanding the current state of uranium resources, the actual lifespan of uranium will be influenced by a multitude of factors, many of which are subject to change over time. The future of uranium as an energy source will depend on our ability to innovate, discover, and manage these resources responsibly.
