BRUNSWICK STEAM ELECTRIC PLANT Status of Tritium Contamination As a result of past operations, residual plumes of tritiated water having concentrations exceeding the EPA drinking water limits [20,000 picoCuries.per liter (pCi/I)] exist in the shallow aquifer within the owner controlled areas.
The ultimate source of the elevated tritium (H-3) was the discharge of turbine building (TB) chiller condensate which contained H-3 resulting from extensive steam leaks to the TB atmosphere. Condensate released from the TB chillers contained H-3 concentrations exceeding 1 E+6 pCi/I. The chiller condensate was routed through storm drain piping (non-radioactive waste piping) to a storm drain stabilization basin and ultimately to the storm drain stabilization pond (SDSP). In CY 2007, the licensee stopped TB chiller condensate releases to the storm drain piping by routing the equipment discharge to the onsite radioactive waste (radwaste) system. The majority of sources for unmonitored tritium release to the subsurface aquifer currently appear to be addressed. However, residual water pumped from onsite-seismic structural gaps continue to have quantifiable tritium which continues to be discharged through the storm drain system.
Batch releases from the SDSP are described in the ODCM as part of the licensee's normal effluent pathways with those discharges made to the intake canal. However, until calendar year (CY) 2007, the licensee failed to recognize the potential unmonitored movement/discharge of tritiated water to the subsurface aquifer from the storm drain piping, from downward migration of SDSP water, or through evaporative processes to the surrounding environs. The licensee currently is monitoring and continuing to evaluate offsite doses from all of those pathways. To date, calculated release concentrations and resultant doses to offsite locations are significantly less than 10 CFR Part 20 Appendix B or 10 CFR Part 50 Appendix I criteria.
As a result of many years of direct releases of TB chiller effluents ultimately to the SDSP, the licensee has identified two distinct areas, beneath the SDSP and beneath the switch yard.
where subsurface (shallow) plumes of tritiated water exceeding the EPA drinking water limit exist. Sampling wells in the shallow, intermediate, and deep aquifer established to monitor discharges from the SDSP have confirmed that all tritium concentrations exceeding EPA drinking water limits remain confined to the shallow aquifer within the owner controlled property and are not currently having a significant impact on offsite locations, or on the drinking water supply for the local population. However, to mitigate any potential future problems from the SDSP, the licensee is moving forward with extensive active remediation activities including construction of a new double-lined stabilization pond, recovery of the contaminated water beneath the SDSP, and subsequent release of the resultant liquid through normal liquid effluent process pathways. The effort is planned for the next several years and currently is awaiting approval from the State of North Carolina to construct a new stabilization pond.
The licensee is exploring a second discrete plume located w/in the switchyard area but the investigation has just begun to map and determine the exact magnitude of this plume. Once additional data are available, the licensee decide any remediation activities for this plume.
