Wood River Junction, Rhode Island

Overview

The village is the site of the former Wood River Branch Railroad Station. The Wood River Branch of the New York, New Haven and Hartford Railroad was chartered in 1872 and completed in 1874. On April 19, 1873 a train disaster was caused by a bridge washout and burning of passenger cars.^[1] The Branch was built to provide service from the Hope Valley to the main line of the New York, Providence and Boston Railroad and was only six miles long. The New Haven Railroad took over operation of the Branch in 1892 and eventually abandoned it on August 8, 1947. The main line continues in operation today as Amtrak's Northeast Corridor.

Criticality accident

On 24 July 1964, a fatal criticality accident occurred^[2] at the Wood River Junction nuclear facility. This facility was designed to recover highly enriched uranium in scrap material from fuel element production. Technician Robert Peabody was working with a tank containing radioactive uranium-235 in a sodium carbonate solution, which was being agitated by a stirrer. Intending to add a bottle of trichloroethane to remove organics, he mistakenly added a bottle of uranium solution to the tank, producing a criticality excursion (uncontrolled chain reaction) accompanied by a flash of light and the splashing of about 20% of the tank's contents (about 10 litres (2.2 imp gal; 2.6 US gal) out of 40 to 50 litres (8.8 to 11.0 imp gal; 11 to 13 US gal), including the bottle contents) out of the tank.

This criticality exposed the 37-year-old Peabody to a fatal radiation dose of "more than 700 rem",^[2] which is 7 Sv. He died 49 hours after the incident.

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) without apparent ill effect.

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