Pacific Northwest National Laboratory Facility Radionuclide Emissions Units and Sampling Systems

Abstract

Battelle-Pacific Northwest Division operates numerous research and development (R&D) laboratories in Richland, WA, including those associated with Pacific Northwest National Laboratory (PNNL) on the U.S. Department of Energy (DOE)'s Hanford Site and PNNL Site that have the potential for radionuclide air emissions. The National Emission Standard for Hazardous Air Pollutants (NESHAP 40 CFR 61, Subparts H and I) requires an assessment of all emission units that have the potential for radionuclide air emissions. Potential emissions are assessed annually by PNNL staff members. Sampling, monitoring, and other regulatory compliance requirements are designated based upon the potential-to-emit dose criteria found in the regulations. The purpose of this document is to describe the facility radionuclide air emission sampling program and provide current and historical facility emission unit system performance, operation, and design information. For sampled systems, a description of the buildings, exhaust units, control technologies, and sample extraction details is provided for each registered emission unit. Additionally, applicable stack sampler configuration drawings, figures, and photographs are provided. Deregistered emission unit details are provided as necessary for up to 5 years post closure. v Acronyms, Abbreviations, and Terms AABC American Air Balance Council ANSI American National Standards Institute CAM continuous air monitor CAP88 Clean Air Act Assessment Package-1988 CFR Code of Federal Regulations cfm cubic feet per minute DEPO Deposition Computer Software Code deregistered A report of closure has been transmitted to the Washington State Department of Health indicating that operations of an emission unit with the potential-to-emit (PTE) radioactive materials has ceased.

“…Hydrogen is an energy carrier that can be produced from diverse domestic resources including fossil fuels, nuclear energy, and renewables such as biomass, wind, and solar. The U.S. produces approximately 10 million metric tons of hydrogen annually with over 90% produced from natural gas and used for petroleum processing and fertilizer production (1,2). While only a small percentage of this hydrogen is consumed by fuel cells, the amount is growing steadily, and worldwide shipments of hydrogen fuel cells increased by 30% between 2016 and 2017 alone (3).…”

Data Quality Objectives Supporting Radiological Air Emissions Monitoring for the PNNL Richland Campus

“…The characteristics of these units relevant to environmental modeling are tabulated (Table 3.4). The characteristics indicated are those based on present operations (Barnett et al 2015). Additionally, LSLII and RTL-520 currently have no active radiological laboratories; therefore, the pairs of stacks at these buildings comprising the emission units for these facilities were each assumed to be a single stack.…”
