The employee was exposed to a radiation dose of less than 10 mrem, or millirem, which is about similar to getting a chest x-ray, according to Nuclear Regulatory Commission
Officials say a Holtec employee was splashed with radioactive water in late February when a lid came off a storage cask at the defunct New Jersey nuclear power plant.
The Oyster Creek nuclear power plant, which is undergoing decommissioning, was cited by federal regulators for a low-level safety violation, the Asbury Park Press reported Wednesday.
Officials say the employee was wearing protective gear and was checked for contamination before returning to work.
Neil Sheehan, a spokesperson for the Nuclear Regulatory Commission, said that a test of a lid seal resulted in a leak through the cask’s vent. The spill occurred when a device used to seal the casks became disengaged after snap rings failed, according to Sheehan.
The contaminated water spilled onto the worker and spread to two levels of the reactor building.
The employee was exposed to a radiation dose of less than 10 mrem, or millirem.
“To put that dose in perspective, the annual occupational dose limit for nuclear power plant workers is 5,000 millirems, or 5 rems,” Sheehan said.
