Final answer:
True, the storage of radioactive waste is a critical concern in the nuclear industry. Lack of a permanent disposal method results in the accumulation of dangerous radioactive material in temporary facilities, posing environmental and safety risks.
Step-by-step explanation:
The statement is true: the storage of radioactive waste is indeed a significant and unresolved issue in the nuclear industry. High-level radioactive waste from nuclear reactors, such as spent nuclear fuel, remains dangerous for thousands of years and necessitates secure storage options. Currently, the primary methods of storage include submerged in pools of water to cool the waste and shield radiation, or in dry storage with special outdoor concrete or steel containers with air cooling. However, there exists no long-term disposal solution within the United States, and potential sites must meet strict geological stability requirements to prevent soil, air, or water contamination. Moreover, nuclear waste can pose safety risks, including the potential for making 'dirty' bombs if it falls into the wrong hands, and carries political challenges due to the 'not in my backyard' syndrome. Alternatives such as underground salt domes have been considered, but finding a universally accepted solution remains politically and technically challenging.
