Abstract
Techniques for storing nuclear waste hazardous material include identifying a storage area of a directional wellbore formed from a terranean surface and extending into a subterranean formation; circulating a slurry that includes a hardenable material and one or more portions of nuclear waste hazardous material into the storage area; forming a seal in the directional wellbore that isolates the storage area of the directional wellbore from an entry of the directional wellbore; monitoring at least one variable associated with the one or more portions of nuclear waste hazardous material from a sensor positioned proximate the storage area; recording the monitored variable at the terranean surface; and based on the monitored variable exceeding a threshold value, removing the seal from the wellbore and retrieving at least a portion of the slurry from the storage area to the terranean surface.
