Operational Awareness Record, Design and Modification Progress Underground Interim Ventilation System at the Waste Isolation Pilot Plant
The U.S. Department of Energy (DOE) Office of Environment, Safety and Health Assessments, within the Office of Enterprise Assessments (EA), is reviewing the design, installation, and startup of upgrades to the WIPP Underground Ventilation System (UVS). These upgrades include an Interim Ventilation System (IVS), a Supplemental Ventilation System (SVS), and a Permanent Ventilation System (PVS). The IVS is a modification intended to increase ventilation through high-efficiency particulate air (HEPA) filters, from 60,000 cubic feet per minute (cfm) to 114,000 cfm by the addition of 2 skid-mounted 27,000 cfm HEPA filter units and fans. The SVS is a further modification of the UVS, with the addition of an underground fan to provide an unfiltered ventilation circuit that will increase capacity to support additional WIPP recovery tasks, including mining, maintenance, and waste emplacement activities. The PVS is intended to increase the capacity of the UVS to a nominal 540,000 cfm.
