NUM-G-2100 GENERAL The owner shall specify environmental conditions for operation and storage. This equipmentshall be designed to withstand the effects of the conditions specified herein. Where the ability of the equipment to withstand the effects is unknown or limited, the manufacturer shall specify such limitations and their basis for acceptance by the owner prior to order. NUM-G-2110 Clearances The crane or monorail shall be designed to provide clearance between the equipment and the building and surrounding obstructions. For traveling cranes, jib cranes, and monorails, at least 3 in. of clearance shall be provided between the highest point of a moving crane or monorail component and the lowest overhead obstruction after taking into account variables that affect the elevation of the overhead structure relative to the equipment, including, but not limited to, external loads such as snow, wind, etc. The clearance between the sides and ends of traveling cranes, jib booms, or hoist and trolley units and the building columns and other ob- structions shall not be less than 2 in. with the crane centered on the runway rails and the hoist and trolley unit centered on the operating flange. In addition, the equipmentmustclear the obstructions whenoperational variables including, but not limited to, maximum wheel float, crane skew, rail alignment, civil installation toler- ances, and thermal expansion are considered. NUM-G-2200 RADIATION (a) The owner shall specify the accumulated radiation dosage expected to be seen by the crane, hoist, or mono- rail, over the life of the nuclear facility. (b) Components whose normal life could be reduced bythe effects ofthe specified radiation shall be tabulated and submitted to the owner. (c) Components of equipment whose failure due to specified radiation could result in loss of load either shall be designed to withstand the specified radiation or shall have a specific replacement period. Where state of the art is such that sufficient data is not available, periodicinspections shallbemade bytheownertodeter- mine when replacement should be made. The inspection requirements and their bases are to be specified by the manufacturer and provided to the owner. 2 NUM-G-2300 TEMPERATURE (a) The owner shall specify the following temperature requirements inthe areawhere the crane, hoist, ormono- rail operates: (1) maximum operating temperature (2) minimum operating temperature (3) ambient temperature for motors (4) maximum construction temperature (5) minimum construction temperature (b) The crane, hoist, or monorail shall be designed to withstand the effects of the specified temperatures, or the limitation of the equipment’s design concerning these temperature conditions shall be specified by the manufacturer. The inspection requirements and their bases are to be specified by the manufacturer and pro- vided to the owner. NUM-G-2400 PRESSURE (a) The owner shall specify the following pressure requirements intheareawhere the crane,hoist, ormono- rail operates: (1) normal operating pressure (2) any test or abnormal event pressures including the rate of change of pressures (b) The crane, hoist, or monorail shall be designed to withstand the effects of the specified pressures, or the limitations of the equipment’s design concerning these pressure conditions shall be specified by the manufac- turer. Specifically where there are changes in pressure, enclosures shall be vented. The inspection requirements and their bases are to be specified by the manufacturer and provided to the owner. NUM-G-2500 HUMIDITY (a) The owner shall specify the humidity conditions in the area where the crane, hoist, or monorail operates. (b) The crane, hoist, or monorail shall be designed to withstand the effects of the specified humidity, or the limitations of the equipment’s design concerning the humidity condition shall be specified by the manufac- turer. The inspection requirements and their bases are to be specified by the manufacturer and provided to the owner.
