Dear Mr. McSweeney:
In response to an Institute of Nuclear Power Operations (INPO) recommendation for corrosion control of copper alloys, the Pilgrim Nuclear Power Station (PNPS) is requesting approval to add the corrosion inhibitor Tolytriazole to the reactor building and turbine building closed cooling water systems, station heating and the emergency diesel generator cooling water systems. During system maintenance activities requiring full and/or partial system drain downs, the cooling water from these systems would be directed to our neutralizing sump, (NPDES Permit Discharge Point #011).
Tolytriazole would be discharged from PNPS Discharge Point #011 only during scheduled plant outages, and during any unplanned system maintenance evolutions.
The maximum concentration of Tolytriazole in the neutralizing sump prior to dilution would be 20 mg/L (PPM). The concentration after dilution, prior to discharge to Cape Cod Bay, would be approximately 2.35 PPM with one Salt Service Water pump to just 0.03 PPM with one Circulating Water pump in operation. These concentrations are below the acute and chronic toxicities reported for this chemical.
L Attached are the technical bulletin and material safety data sheets for Cobratec TT S the brand of tolytriazole that would be used. Initial conditioning requires levels of 20 I PPM in the treated systems, but after this concentrations would be maintained at 2 PPM. Tolytriazole is commonly used in these concentrations for copper alloy corrosion control by many industries.
I We would appreciate your written approval for the use of this chemical at PNPS as described above, as soon as possible. Please contact Mr. Robert D. Anderson at (508) 830-7935 should you 1eed further information regarding this matter.
