ASME NML-1 pdf download.Rules for the Movement of Loads Using Overhead Handling Equipment in Nuclear Facilities.
Movement of loads covered by this Standard shall be in accordance with the Standard’s requirements but not necessarily with its recommendations. The word shall is used to denote a requirement, the word “should is used to denote a recommendation, and the word may’ is used to denote permission, which is neither a requirement nor a recommendation.
1-2 SCOPE
This Standard specifies requirements for the movement of loads using overhead handling systems at commercial nuclear facilities.
(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 1330.2
(-c) ASME 1330.5
(-d) A.SME 1330.16
(-e) ASME B30.17
(-D ASME 1330.21
(.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
j’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.
1-3 APPLICABILITY
This Standard applies to all lifting and handling operations at nuclear facilities, including the training and certification of personnel, and the maintenance, inspection. testing, and rework and modification of overhead handling systems and other lifting devices.
The application of this Standard shall begin at the point of initial fuel load at the affected unit under construction.
(0) The crane operator shall be familiar with the equipment and its proper care. If adjustments or repairs are necessary or any defects are known, the crane operator shall report them In accordance with the program described in subsection 4-3.
（U) Contacts with runway stops or other cranes shall be made with extreme caution. The crane operator shall do so with particular care for the safety of persons on or below the crane, and only after making certain that any persons on the other cranes are aware of what is being done.
(k) When the wind-indicating device of a cab-operated outdoor crane gives a wind excessive alarm, crane opera. tion shall be discontinued at first opportunity, any suspended loads shall be landed, and the crane shall be prepared and stored for excessive wind conditions.
(I) Prior to the performance of any maintenance work on the crane, the crane shall be locked and tagged out (crane disconnect) in the de.energized position in accordance with facility procedures unless maintenance or troubleshooting activity cannot be performed without power. Additional caution should be used when additional personnel are present on the crane.
(m) Before beginning a new shift or at the earliest opportunity if a mid-evolution turnover is made between the new and leaving operators and it is impractical to perform the tests due to the crane configuration, the crane operator shall test control master switches, push buttons, and, if provided and scheduled for use, radio controls.
(n) If at any time controls do not operate properly, the crane operator shall report the malfunction in accordance with the program described in subsection 4-3.
(o) The crane operator shall enter and exit overhead cranes only at authorized locations and designated boarding entrances except in emergency situations.
(p) lithe crane has more than one hoisting unit, the operator shall lift only loads that are within the rated load capacity of the hoist and crane structure.
3-1.3 Crane Operator Physical Requirements
Crane operators and crane operator trainees shall meet the following physical qualifications:
(a) vision of at least 20/30 Snellen in one eye and 20/50 Snellen in the other, with or without corrective lenses.
