The Defense Nuclear Facilities Safety Board (DNFSB), an independent government organization responsible for overseeing public health and safety issues at Department of Energy defense nuclear facilities, has alerted the DOE because of safety concerns it has regarding the use of continuous air monitors (CAM) at the Waste Isolation Pilot Plant in New Mexico.

Part of WIPP’s new Safety Significant Confinement Ventilation System (SSCVS), the CAM system is intended to detect a radiological release in the repository and automatically close vent dampers to prevent the escape of radioactive particles to the outside environment. The SSCVS, which began commissioning in November 2023, is intended to increase airflow to the underground to allow for simultaneous underground waste emplacement, mining, and ground control work.

Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.
