20555 Attention:
Mr. Olan D. Parr, Chief Gentlemen:
Light Water Reactors Branch 3 Division of Project Management SECONDARY WATER CHEMISTRY CONTROL PROGRAM NO. 2 UNIT SALEM NUCLEAR GENERATING STATION DOCKET NO. 50-311 We are in receipt of your letter of January 31, 1980 in which you provided a satisfactory evaluation of the Salem 2 proposed secondary water chemistry control program.
In your letter you requested that, in addition to our proposed pro-gram, the steam condensate at the effluent of the condensate pump be monitoredo In response to your request, we are pro-viding our revised secondary water chemistry control program which incorporates the monitoring of the steam condensate at the effluent of the condensate pump, as requested.
Should you have any questions in this regard, please do not hesitate to contact us.
HIS Very truly yours~

SECONDARY WATER CHEMISTRY CONTROL PROGRAM NO. 2 UNIT SALEM NUCLEAR GENERATING STATION The Secondary Water Chemistry Control Program is designed to limit the corrosion of the tubing and internals of the steam generators.
The basis of the program is to control the lev-els of the critical parameters in the steam generator bulk water such that maximum protection to the steam generators is provided and tube integrity is maintained.
This is accomplished by maintaining the water quality of the condensate and condensate polishing effluent and adjusting the blowdown on each of the four steam generators.
The feedwater and steam generator bulk water treatment consists of introducing ammonia for pH control and hydrazine for oxy-gen scavenging.
This treatment is recommended by the West-inghouse Electric Corporation.
CRITICAL PARAMETERS The critical parameters measured in each of the four steam generator blowdown samples include:
pH, cation conductiv-ity, chloride and free hydroxide.
The critical parameters measured in the condensate as sampled at the condensate pump discharge and the condensate polishing effluent include:
cation conductivity and sodium.
CONTROL POINTS Normal limits of control are identified in Table 1.
SAMPLING SCHEDULE The sampling schedule selected to maintain the critical par-ameters within the normal limits of control as indicated on Table 1 consists of obtaining and analyzing blowdown samples from each of the steam generators, four times in each seven day period, with no more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> between samples.
The sample frequency is increased when the normal limits of con-trol are exceeded to assure that the Unit is operated within the limiting specifications as indicated on Table 2.
Thi condensate and the condensate polishing effluent will be monitored on a continuous basis with recording meters.
MEASUREMENT METHODS The critical parameters are measured as follows:
Meters -
pH, cation conductivity, sodium Titrations -
chlorides and free hydroxides SAMPLING LOCATION Periodic samples are obtained as indicated in the sampling schedule from each of the four steam generators as well as the condensate and condensate polishing effluent.
DATA MANAGEMENT The steam generator analysis is* recorded on the daily read-ing sheet.
The Technical Supervisor in charge of the Sec-ondary Water Chemistry Control Program has the specific re-sponsibility to direct the program.
The data is reviewed by the Senior Performance Supervisor in charge of Chemistry as well as the Station Performance Engineer.
Periodically, the data is reviewed by the General Off ice of the Electric Pro-duction Department as well as the Westinghouse Electric Cor-poration.
The daily reading sheets are incorporated into the permanent Station records.
CORRECTIVE ACTIONS Whenever the normal limits of control are exceeded, the Sen-ior Performance Supervisor in charge of Chemistry and the Station Performance Engineer review the data and initiate the necessary corrective actions to return the Secondary Water Chemistry to within the normal control limits as quickly as possible.
The off-control point chemistry must be returned to within the normal limits of control in the times specified in the limiting specifications contained in Table 2.
In the event that the limiting specifications cannot be maintained, the data is reviewed by the Station Manager who will initiate additional corrective actions which can include removing the Unit from service 'if conditions warrant this course of action.
Should a condenser leak be confirmed, the leak will be re-paired or the leaking tube plugged, within 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br />.
