How is high-level nuclear waste being handled presently in the United States?

• A. Yucca Mountain
• B. On-site Landfill
• C. Pacific Ocean Dump
• D. Reprocessing Facility in Savannah River

Answer: (A)

The important idea is long-term isolation of high-level waste. In the United States, the goal has been to place most spent nuclear fuel in a single deep geological repository so it is physically separated from people and the environment for very long times. Among the options given, the one that represents that centralized disposal plan is the idea of a national geologic repository at Yucca Mountain. That choice captures the intended approach of isolating high-level waste in a dedicated facility. The other options don’t fit how high-level waste is handled. An on-site landfill isn’t used for high-level waste, which must be kept secure and isolated. Dumping into the Pacific Ocean would be illegal and dangerous. A reprocessing facility in Savannah River pertains to reprocessing spent fuel to recover materials, not the disposal of the high-level waste itself, and the United States does not presently operate such civilian reprocessing for disposal purposes. In reality, there’s no active national repository at Yucca Mountain, so most high-level waste remains at reactor sites in storage until a disposal path is available.
