Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract]
NuScale Reverse Recapitalization	NuScale Reverse Recapitalization In the second quarter of 2022, NuScale became a public company (ticker:SMR) through a reverse recapitalization with a public shell company, Spring Valley, resulting in the net receipt of $341 million of cash and the assumption of $48 million of warrant liabilities exercisable for shares of SMR. We continue to control and consolidate NuScale. The impacts of the transaction are recognized in our third quarter results. Under the reverse recapitalization, NuScale was the accounting acquirer of Spring Valley which held no significant assets or liabilities requiring fair value re-assessment (outside of cash and warrant liabilities).
