In an Offsite Notification filing with the Nuclear Regulatory Commission (NRC), the Peach Bottom nuclear power station in Delta, Pennsylvania, reported the spill and release of Sodium Hypochlorite from a tank at the plant’s water treatment facility Monday morning.
According to the filing with the NRC the Peach Bottom nuclear station reported a spill and release of Sodium Hypochlorite from its water treatment plant’s Sodium Hypochlorite tank, which is currently in progress at an estimated rate of approximately 1 gpm to the surrounding soil area.
Sodium Hypochlorite is widely used for bleaching purposes, and to treat water and wastewater. Peach Bottom nuclear power station’s Unit 2 and Unit 3 use two General Electric boiling water nuclear reactors in which water, used as both a coolant and moderator, boils in the reactor core. The steam from the boiling water is then used to turn electrical turbine generators.
The leak began by entering the surrounding moat area and is believed to have subsequently impacted or potentially impacted the Susquehanna River due to release through a storm drain.
Measures being taken by Peach Bottom operators to control the leak include installation of additional barriers to the release and contacting the Lewis Environmental Hazard Mat team to address the incident at the site. In addition, a truck has been dispatched to the site to pump out the moat.
The cause of the leak is still under investigation by plant officials.
Peach Bottom nuclear power station produces more than 2,200-megawatts of electricity, powering more than two million homes.
