INTRODUCTIONThis presentation is an overviewof the contents of the 2012 Editionof AG-1, which is the latestpublished version of this CodeBook.Dr. Ronald R. Bellamy, ChairASME CONAGTrrb1rrb1@verizon.net3
HISTORY– 1971 ANSI Nuclear Technical Advisory Board Created N45-8 To develop a standard for BWR Standby Gas Treatment Systems– Immediately Expanded to all Engineered Safety FeatureFiltration Systems Issued ANSI N510 in 1975 for Testing of Systems Issued ANSI N509 for Units and Components in 1976– ASME Committee on Nuclear Air and Gas Treatment(CONAGT) Established in February 1976 in New York City Small meeting of experts and US regulators– AG-1 first issued in 1985 as a component based document4
AG-1 USE ANDIMPLEMENTATION- Intended to replace N509 and N510- Create one recognized code for all nuclear facilityventilation and air cleaning requirements that isrecognized world-wide One codified document Endorsed by United States Nuclear Regulatory Commission- Used, recognized and incorporated either directly or byreference by countries worldwide. This effort mustcontinue as we work towards our goal of improvingpublic health and safety5
TRAININGOPPORTUNITIES– Many Opportunities to learn what is in AG-1 ASME computerized training on code use through the ASMEwebsite Harvard University School of Public Health In-Place FilterTesting Workshop Corporation-sponsored training Specific onsite training of AG-1 tailored to your needs International Nuclear Air Cleaning Conferences Become involved as a member of CONAGT– Two meetings per year, corresponding membership provides inputwithout attendance at meetings6
SCOPE AND PURPOSEAG-1SCOPEThis Code provides requirements for the performance, design,fabrication, installation, inspection, acceptance testing, andquality assurance of equipment used in air and gas treatmentsystems in nuclear facilities.PURPOSEThe purpose of this Code is to ensure that equipment used innuclear facilities for air and gas treatmentsystems is acceptable in all aspects of design and operation.7
APPLICABILITYAG-1AG-1 applies only to individual components in a system. The Codedoes not cover any functional system design requirements or sizingof complete systems, or any operating characteristics of thesesystems. The responsibility for meeting each requirement of thisCode shall be assigned to the Owner or assigned designee. Therequirements of AG-1 for air and gas treatment components may beused for engineered safety features systems and normal systems innuclear power generation facilities, and for air cleaning systems inother nuclear facilities. The design and procurement specificationsshall delineate the design, qualification and quality assurancerequirements appropriate for the application.8
CONTENT OF AG-1The ASME Code on Nuclear Air and Gas Treatmentconsists of Divisions I through IV. All Divisions arebroken down into Sections designated by two capitalletters. Division 1 – General Requirements Division 2 – Air Cleaning Equipment Division 3 – Gas Process Treatment Equipment Division 4 – Testing9

FUTURE CHANGES TO AG-1AG-1-2014(with editor for final publication) ASME Publications - Elimination of Addenda 2 Year AG-1 Code Publication Cycle Planned New Code Sections & Appendices:– Section FI – Metal Media Filters– Section FM - High Strength HEPA Filters– Section GC – Compressors (in 2014 edition)– Section GM - Adsorbers– Maintenance Revisions16
SUMMARYThis Code Book (AG-1 ) has over 40 years ofexperience built into its pages. Industry volunteerand ASME staff participation along with Owners,Regulators, Insurance Inspectors, Manufacturers,and the Public have all contributed to make thisCode Book the world’s choice for high reliability aircleaning equipment. We will continue to work onthis Code and respond to industry needs.17
