ASME AG-1-2009 pdf download.Code on Nuclear Air and Gas Treatment.
AA-1100 SCOPE This Code provides requirements for the performance, design, construction, acceptance testing, and quality assurance of equipment used as components in nuclear safety-related air and gas treatment systems in nuclear facilities. AA-1110 PURPOSE The purpose of this Code is to ensure that equipment used in nuclear facilities for nuclear safety-related air and gas treatment systems is acceptable in all aspects of performance, design, construction, and testing. AA-1120 APPLICABILITY This Code applies only to individual components in a system. This Code does not cover any functional system design requirements or sizing of complete sys- tems, or any operating characteristics of these systems. The responsibility for meeting each requirement of this Code shall be assigned to the Owner or assigned designee. AA-1130 DEFINITIONS AND TERMS Each Code section shall delineate the definitions and terms unique to that section. Definitions that have common application are listed in this section. acceptance test: a test made upon completion of fabrica- tion, installation, repair, or modification of a unit, component, or part to verify to the user or Owner that the item meets specified requirements. active component: any component that must perform a mechanical motion or change of state during the course of accomplishing a nuclear safety-related function. 4 air density: 0.075 lb /ft 3 (1.201 kg /m 3 ) for standard air. This corresponds to air at a pressure of 29.92 in. Hg (760 mm Hg) at a temperature of 69.8°F (21°C) with a specific volume of 13.33 ft 3 /lb (0.832 m 3 /kg). airflow (ACFM, SCFM, ACMS, SCMS): expressed in terms of CFM (cubic feet of air per minute). ACFM is a cubic foot of air with a density at actual existing conditions. SCFM (standard CFM) is a cubic foot of air with a standard density. ACMS and SCMS correspondingly apply to cubic meters per second under actual and standard conditions. allowable deflection (d all ): the deflection resulting from each of the component loading conditions defined in AA-4212. allowable stress value (S): the maximum stress limit to be used in the design. assembly: two or more devices sharing a common mounting or supporting structure. broadband response spectrum: a response spectrum that describes the motion indicating that multiple frequency excitation predominates. Certificate of Compliance: a written statement, signed by a qualified party, attesting that the items or services are in accordance with specified requirements and ac- companied by additional information to substantiate the statement. Certificate ofConformance: a written statement, signed by a qualified party, certifying that items or services comply with specific requirements. clean air system: an air cleaning system that is designed to maintain a definite level of air cleanliness within an enclosed working area. component: a constituent of any referenced item. For example, an adsorber is a component of an air cleaning unit. An air cleaning unit and ducts are components of the air cleaning system.
component conditions: operating conditions of a compo- nent referred to as Service Level A, Service Level B, Service Level C, or Service Level D. contained space: a building, building space, room, cell, glove box, or other enclosed volume in which air supply and exhaust are controlled. contaminated exhaust system: an air cleaning system that is designed to remove harmful or potentially harmful particulates, mists, or gases from the air or gas exhausted from a contained space or process. contaminated space: any enclosed or outdoor space with actual or potential airborne concentrations of haz- ardous or radioactive materials that may cause one or both of the following: (a) unacceptable damage or dose to personnel and equipment occupying the space (b) contamination of other spaces contamination: any unwanted material in the air or on surfaces. For the purpose of this Code, contamination is usually assumed to be hazardous or radioactive. contamination zone: an isolated area that is or that could become contaminated and that is designed to facilitate decontamination. Contractor: any organization under contract for furnish- ing items or services to an organization operating in compliance with this Code. It includes the terms Vendor, supplier, subcontractor, and Fabricator, and subtier lev- els of these where appropriate, but excludes Material Suppliers and Material Manufacturers. decibel (dB): a numerical expression of the relative loudness of a sound, which is a dimensionless quantity, used to express a level in logarithmic terms of the ratio of a quantity to a reference for sound pressure, which is 0.0002 dyne /cm 2 ; and for sound power that reference is 10 −12 W. decontamination: the removal of contamination from the air or surfaces. design specification: a concise document defining tech- nical requirements in sufficient detail to form the basis for a product, material, or process that indicates, when appropriate, the procedure or means that determines whether or not the given requirements are satisfied. The design specification includes requirements for per- formance and testing. design working pressure: the maximum allowable work- ing pressure for which a specific part of a system is designed. 5 device: an item, component, or accessory that is used in connection with, or as an auxiliary to, other items of equipment. driver: a prime mover that produces rotational power input to the driven equipment. For the purpose of this Code, the term driver will be understood to be an AC induction motor. Other types of drivers are not covered by this section of the Code. duct: an air or gas path enclosure. effective width: a reduced width of plate that is effective in carrying loads after the local buckling stress has been exceeded. These effective plate regions are adjacent to stiffeners, or at corners where two or more joined plates stiffen one another. Forty to fifty plate thicknesses are normally considered as effective in acting with the stiffeners. Engineer: as used in this document, the Engineer is the individual or organization designated by the Owner to be responsible for the original design or modification to the original design of air and gas treatment systems, and is responsible for determining the performance parameters for the system.
