NML - Rules for the Movement of Loads Using Overhead Handling Equipment in Nuclear Facilities

This Standard specifies requirements for the movement of loads using overhead handling systems at commercial nuclear and other high risk facilities.?Nuclear facilities can include nuclear power plants (NPP), small modular reactors (SMR), and advanced reactors. 

(a) For the purposes of this Standard, overhead handling systems are limited to the following: 
(1) those types covered by the following standards: 
(-a) ASME B30.1, Chapter 1-6, Telescopic Hydraulic Gantry Systems; and Chapter 1-7, Strand Jack Systems 
(-b) ASME B30.2 
(-c) ASME B30.5 
(-d) ASME B30.16 
(-e) ASME B30.17 
(-f) ASME B30.21 
(-g) ASME NOG-1 
(-h) ASME NUM-1 
(2) those defined as engineered temporary lift assemblies per subsection 1-5 
(3) those qualified as special designed equipment per ASME HRT-1 
(b) This Standard does not cover the individual movement of irradiated fuel assemblies that are bounded by a facility accident analysis. 
(c) Lifts licensed under 10 C.F.R. 72 are within the scope of this Standard.

Standard covers movement of loads using overhead handling systems at commercial nuclear facilities, limited to an Engineered Temporary Lift Assembly, Special Designed Lifting Systems which meet the requirements of HRT-1, or B30 standards.
