Now, fallout from the global coronavirus pandemic is resulting in more challenges as the Waste Isolation Pilot Plant, the nation's only underground repository for nuclear waste, finished ramping down operations Wednesday, April 1, 2020, to keep workers safe.
The Energy Department has estimated that the repository would need to operate at least another three decades — if not longer — to meet disposal needs.
The GAO stated that there are significant risks that could delay the schedule and the Energy Department failed to compensate for the risks by including additional contingency time.
The GAO noted that both projects are facing challenges with identifying and overseeing contractors and getting necessary regulatory approvals.
