Restricted Cash And Cash Equivalents [Abstract]
Restricted Cash and Cash Equivalents	24. Restricted Cash and Cash Equivalents As of December 31, 2023, restricted cash and cash equivalents totaled $3.5 million ($80.4 million as of December 31, 2022), and primarily consisted of net proceeds from the issuance of $197.0 million in August 2021 and $162.6 million in July 2020 of 40-year variable-rate Green Bonds. The restricted cash and cash equivalents related to the debt issuance are being held in a trust account and will be used to partially fund the capital costs, in particular the expenditures associated with pollution prevention and control (including waste recycling and waste reduction), of the construction of Nucor’s plate mill located in Brandenburg, Kentucky. Funds will be disbursed from the trust account as qualified expenditures for the construction of the Brandenburg facility are made ($78.9 million during 2023 and $64.2 million during 2022). Interest earned on funds held in the trust account is subject to the same usage requirements as the bond proceeds principal. Since the restricted cash, interest and dividends must be used for the construction of the Brandenburg facility and relate to a long-term liability, the entire balance has been classified as a non-current asset.
