Section 223 of the Atomic Energy Act of 1954, as amended, provides for criminal sanctions for willful violation of, attempted violation of, or conspiracy to violate, any regulation issued under sections 161b, 161i, or 161o of the Act. For purposes of section 223, all the regulations in part 73 are issued under one or more of sections 161b, 161i, or 161o, except for the sections listed in paragraph (b) of this section.

The regulations in part 73 that are not issued under sections 161b, 161i, or 161o for the purposes of section 223 are as follows: §§ 73.1, 73.2, 73.3, 73.4, 73.5, 73.6, 73.8, 73.25, 73.45, 73.75, 73.80, and 73.81.

No person without authorization may carry, transport, or otherwise introduce or cause to be introduced any dangerous weapon, explosive, or other dangerous instrument or material likely to produce substantial injury or damage to persons or property into or upon a protected facility or installation. Willful violations of this provision are punishable by the criminal penalties set forth in sections 229b and 229c of the Atomic Energy Act of 1954, as amended.

As used in this section:

“Protected facility or installation” means any production or utilization facility, high-level waste storage or disposal facility, independent spent fuel storage installation, uranium enrichment, uranium conversion, or nuclear fuel fabrication facility, but does not include those portions of such facilities that are not required under § 73.75(b) of this part to be identified by notices posted at their pedestrian and vehicle entrances, and does not include facilities described in § 73.75(c) of this part.

“Without authorization” means not authorized as part of one's official duties to carry the weapon, explosive, or other instrument or material;

“Dangerous weapon” includes any firearm, as defined in either 18 U.S.C. 921 or 26 U.S.C. 5845, or dangerous weapon, as defined in 18 U.S.C. 930;

“Explosive” means any explosive as defined in 18 U.S.C. 844(j).

An item, such as a dangerous weapon, explosive, or other dangerous instrument or material, is considered to have been carried, transported, or otherwise introduced or caused to be introduced into or upon a protected facility or installation for purposes of paragraph (c)(1) of this section once the item has traveled past a notice posted pursuant to § 73.75 of this part at a vehicle or pedestrian entrance to the protected facility, or once the item has entered the protected facility or installation at a location that is not a vehicle or pedestrian entrance to the facility, whether such entry is accomplished through, over, under, or around a fence, wall, floor, roof, or other structural barrier enclosing the protected facility or installation or by any other means.

For all protected facilities or installations that do not possess special nuclear material, byproduct material, or source material as of the effective date of this rule, this provision shall take effect upon receipt of such material at the applicable facility or installation.
