ingress in the PWR secondary feedwater. The combination of impurity ingress with corrosion of copper containing alloys and corrosion product transport (Fe 0 , Ni0 , etc.) in the secondary 3 4 2 water system produces sludge that is difficult to remove and is reactive to steam generator materials. In reporting the program, the following guidelines should be observed: 79 (a) Monitor the condensate water quality at the condensate pump discharge as a minimum. Supplement as necessary by samples from the condenser hot well and condenser discharge. (b) Measure the cation conductivity and oxygen. (c) Maintain condensate impurity level at 0.1 ppm ± 0.05 ppm, oxygen at 5 ppb. (d) A cation conductivity increase of 5 to 10 µS/m (0.05 to 0.10 µmho/cm) justifies on-line investigation of possible 80 contamination. (e) An increase of 10 to 20 µS/m (0.10 to 0.20 µmho/cm) is 81 considered an indication of condenser leakage. (f) When a condenser leak is confirmed, the leak should be repaired or plugged within 96 hours, or before the total integrated conductivity increase reaches 2000 µS/m hrs (20 µmho/cm hrs). 82 The staff will consider other impurity-time limit proposals for limiting the quantity of impurities entering the steam generator. (2) Identify the procedures used to measure the value of each of the critical parameters. Provide the procedure title, the applicant/licensee's procedure number, and the basis (i.e., ASTM No.). (3) Identify sampling points. The program should consider sampling the steam generator blowdown, the hot well discharge, the feedwater, and demineralizer effluent as a minimum of sampling points. (4) State the procedure for recording and management of data. (5) State the procedures defining corrective action for various out-of-specification parameters. The procedures should define the allowable time for correction of out-of-specification chemistry. DRAFT Rev. 3 - April 1996 5.4.2.1-18 (6) Identify (a) the authority responsible for the interpretation
