ASME AG-1 REQUIREMENT EXEMPTION JUSTIFICATIONS FOR VENTILATION SYSTEMS AT NUCLEAR WASTE STORAGE TANKS AT THE HANFORD SITE
Washington State Department of Health regulations require compliance with the American Society of Mechanical Engineers (ASME) AG-1, ''Code on Nuclear Air and Gas Treatment,'' for all new radioactive air emission units. As a result, these requirements have been applied to systems that ventilate the radioactive waste storage tanks in the tank farm facilities on the U.S. Department of Energy's Hanford Site. ASME AG-1 is applied as a regulatory constraint to waste tank ventilation systems at the Hanford Site, even though the code was not intended for these systems. An assessment was performed to identify which requirements should be exempted for waste tank ventilation systems. The technical justifications for requirement exemptions were prepared and presented to the regulator. The technical justifications were documented so that select requirement exemptions for specific projects and systems can be sought through the regulator's permitting process. This paper presents the rationale for attempting to receive requirement exemption and presents examples of the technical justifications that form the basis for these exemptions.
