Content:
zones and all exterior areas within the protected area shall be provided with illumination sufficient for the monitoring and observation requirements of paragraphs (c)(3) , (e)(8) , (h)(4) and (h)(6) of this section, but not less than 0.2 footcandle measured horizontally at ground level. ( 5 ) Strategic special nuclear material, other than alloys, fuel elements or fuel assemblies, shall: ( i ) Be stored in a vault when not undergoing processing if the material can be used directly in the manufacture of a nuclear explosive device. Vaults used to protect such material shall be capable of preventing entry to stored SSNM by a single action in a forced entry attempt, except as such single action would both destroy the barrier and render contained SSNM incapable of being removed, and shall provide sufficient delay to prevent removal of stored SSNM prior to arrival of response personnel capable of neutralizing the design basis threat stated in § 73.1 . ( ii ) Be stored in tamper-indicating containers; ( iii ) Be processed only in material access areas constructed with barriers that provide significant delay to penetration; and ( iv ) Be kept in locked compartments or locked process equipment while undergoing processing except when personally attended. ( 6 ) Enriched uranium scrap (enriched to 20% or greater) in the form of small pieces, cuttings, chips, solutions or in other forms which result from a manufacturing process, contained in 30 gallon or larger containers with a uranium-235 content of less than 0.25 grams per liter, may be stored within a locked and separately fenced area within a larger protected area provided that the storage area fence is no closer than 25 feet to the perimeter of the protected area. The storage area when unoccupied shall be protected by a guard or watchman who shall patrol at intervals not exceeding 4 hours, or by intrusion alarms. ( d ) Access control subsystems and procedures. ( 1 ) A numbered picture badge identification subsystem shall
