  Publication Information
To develop, review, maintain, and coordinate codes and standards for design, fabrication, installation, testing, and inspection of equipment and systems used in air and gas treatment for nuclear facilities. 
As used herein “gas treatment” includes both HVAC and gas processing.

a.   HVAC – the moving and conditioning of air which is supplied, exhausted, or recirculated into and from an enclosed space to maintain prescribed ambient conditions. These conditions include pressure, temperature, humidity, and contaminants.

b.   Gas processing – the transportation of gas and the separation, isolation, and disposal of its constituents by physical, mechanical, chemical, delay, electrical, and thermodynamic means.


What’s new with the “Standards Committee on Nuclear Air and Gas Treatment - CONAGT”?

The ASME AG-1 Code on Nuclear Air and Gas Treatment provides the requirements for the performance, design, fabrication, inspection, and testing of air cleaning and conditioning components and appurtenances used in nuclear facilities. The AG-1 Code is used for nuclear power facilities, nuclear fuel cycle facilities, and the design requirements have been referenced for other types of air cleaning facilities where high reliability and performance are required. The 2017 Edition was published in early 2018.

The ASME Standard for In-Service Testing of Nuclear Air Treatment, Heating, Ventilating, and Air Conditioning Systems, ASME N511, was published in 2007, and reaffirmed in 2013. The 2017 Edition provided further revisions. The Standard provides the requirements for in-service testing of nuclear safety-related air treatment, heating, ventilating, and air conditioning systems in nuclear facilities. This Standard provides the means to verify that the nuclear air treatment, heating, ventilating, and air conditioning systems continue to perform their intended function. In-service testing is conducted to monitor the performance of the equipment and system(s) to provide assurance that they continue to function within their specified design basis limits. The tests enable the user to establish system performance trends by comparing the results to acceptance test reference Values and to previous in-service test results.
