In plain terms. NRCAR is the Nuclear Regulatory Commission's supplement to the FAR, adding NRC-specific acquisition rules.
Who it applies to. Contractors serving the Nuclear Regulatory Commission.
What it requires. Comply with the FAR, then NRCAR additions. NRC work can involve safeguards and security information about nuclear facilities, so expect heightened information-protection and access requirements.
Why it matters. Nuclear safeguards information is highly sensitive, so protection requirements on NRC contracts can be stringent.
Citation. NRCAR, the Nuclear Regulatory Commission Acquisition Regulation supplement to the Federal Acquisition Regulation (FAR), codified in the FAR System at Title 48 of the C.F.R.
