On 24 July 1964 at around 6:06pm, a fatal criticality accident occurred at the United Nuclear Corporation Fuels Recovery Plant near Wood River Junction.[1][2]

Opened on 16 March 1964, the nuclear fuel recycling plant was designed to recover highly enriched uranium from scrap material left over from fuel element production.[3][4] Technician Robert Peabody, intending to add a bottle of trichloroethane to remove organics from a tank containing radioactive uranium-235 in a sodium carbonate solution, mistakenly added a bottle of uranium solution instead. This produced a criticality excursion accompanied by a flash of light. About 10 liters (2.2 imp gal; 2.6 U.S. gal) out of 40 to 50 liters (8.8 to 11.0 imp gal; 11 to 13 U.S. gal) of the tank's contents were splashed out of the tank.[3][5] This criticality exposed the 37-year-old Peabody to a fatal radiation dose exceeding 10,000 rad.[3][6][7] He died 49 hours later from acute radiation syndrome.[7][8]

Ninety minutes later, a second excursion happened when a plant manager returned to the building and turned off the agitator, exposing himself and another administrator to doses of up to 100 rad (1 Gy).[3][6][9]

The local Hope Valley Ambulance Squad (HVAS) responded to render aid, initially transporting Peabody to Westerly Hospital; the hospital was not equipped for such a patient, so the ambulance was redirected to Rhode Island Hospital in Providence.[8][10]

As a result of the incident, the Atomic Energy Commission charged UNC with 14 violations of nuclear safety regulations, however no fines were ever levied against the company.[8] After decontamination, the plant reopened on 1965 and remained in operation until it was decommissioned in 1980.[8] A 1979 aerial survey found radiation exposure rates in the area to be consistent with natural background radiation, except directly over the UNC facility.[11]

Although commonly referred to as taking place in Wood River Junction, the incident actually occurred just across the river in Charlestown.[2]
