Sampling with a rotary drill could potentially cause a fire in some Hanford tanks. If the rotary drill experiences a failure while in fuel-rich, dry waste, the waste could be ignited by the hot drill bit. For the saltcake tanks subject to this hazard, this report presents a methodology for calculating the probabilities of fire due to core drill failure. The methodology utilizes sampling data from tank characterization studies to determine the amount of reactive waste in the tanks
