REQUEST FOR ADDITIONALINFORMATION REGARDING COOLANT CHEMISTRY, NINE MILE POINT NUCLEAR STATION UNIT NO. 1 (TAC NO.
M99130)
Dear Mr. Mueller.
By letter dated July 16, 1998, you submitted a revised application for license amendment to change Technical Specification (TS) 3/4.2.3, "Coolant Chemistry," for Nine Mile Point Nuclear Station, Unit 1 (NMP1). The NRC staff is reviewing the revised application and finds that the following additional information is needed:
The proposed TS changes would add a new TS 3.2.3e requiring shutdown ifconductivity exceeds 0.19 micro mho/cm when chloride or sulfate ion concentrations cannot be determined.
Please provide and justify a database for the correlation between chloride and sulfate ion concentrations verses conductivity that supports this proposed change.
Identify and justifythe possible upper limits for sulfate and chloride coolant concentrations ifconductivity has not exceeded 0.19 micro mho/cm.
We also request that you edit proposed TS 3.2.3a and 3.2.3b by relocating the phrase "for > 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />" to followthe word "limits"and provide revised TS replacement pages.
Your response to this letter is requested within 30 days of its receipt.
Ifyou should have any questions regarding this request or are unable to meet the requested response schedule, please contact me by phone on (301) 415-3049 or by electronic mail at dshOnrc.gov.
