- Response -i Liould Effluent Releases:
On October 17.-1990 low level concentrations of trititan were detected in plant secondary systems. A review of secondary plant
--leakage release points was. performed and indicated that trititan
-had been released from two locations.- low level concentrations
-of tritium were found at the 011/ Water-Separator Vault Nos. 2 and West Feedwater Pipe Chase, both of which discharge-to the=
settling basin.- Samples on the settling basin indicated no > detectable' tritium concentrations. q A review (90TSEV-0007) performed in accordance with NRC Bulletin 80-10 showed the maxinum dose ccanitment of 5.6E-09 mrem would-
-not pose A threat to the public. This review reccmnended that -
"the_ effluents from these-release points be directed to release
-pathways already--identified. The reconsnendations were
-implemented promptly and releases-to unrestricted areas were stopped.
