2014 Discharge Channel Tritium Summary
Dear Mr. Belnick:
This letter fulfils the Brunswick Steam Electric Plant's (BSEP) agreement to provide your office
with summary information regarding concentrations of tritium in discharges from the plant.
The BSEP is providing your office with a summary page containing analytical data regarding
tritium in conjunction with the development and submittal to the U.S. Nuclear Regulatory
Commission of the BSEP's annual Radiological Environmental Operating Report. This
information is being provided with the understanding that it is generated pursuant to the
requirements of the nuclear operating licenses issued by the Nuclear Regulatory Commission
and its predecessors to the plant and is not a requirement of the NPDES program.
If there are any questions please contact Mr. Shannon Langley, at [phone] or Mr. Marty

Enclosure: 2014 BSEP Effluent Tritium Sampling and Data

2014 BSEP Effluent Tritium Sampling and Data
Monthly samples are collected upstream of the ocean discharge pumps which pump water from the
effluent channel into the Atlantic Ocean. The samples are collected over a month time period using a
composite sampler with, typically, 50 milliliter aliquots being collected every 4 hours. One (1) of the
twelve samples from the effluent channel indicated the presence of tritium. The maximum tritium
concentration was 555 pCi/L which was expected due to plant operations at the time of sampling.
