I The purpose of this procedure is to identify a secondary water chemistry monitoring program to maximize the availability and operating life of ma-jor components such as the steam generators and the turbine.

,i 2.0 SCOPE The scope of .s program is limited to:

2.1 Unit One-2.2 Identifica; ion of a sampking schedule for the mininal critical para-meters and control points for these parameters; 2.3 Identification of the procedures used to measure the values of the critical parameters;j 2.4 Identification of sampling procedures and process sampling points, 2.5 Procedure for the recording and management of data; I

(\ 2.6 Procedure defining corrective actions for chemistry conditions out-side normal ranges; and ,

2.7 A procedure identifying the authority responsible for the interpreta-tion of the data, and the sequence and timing of administrative events required to initiate corrective action.

Parameters outside of their normal values represent conditions which could lead to corrosion. The action responses are designed to pro-vide a response in proportion to the severity of the situation en-countered.

4.2 Corporate Management - Utility management responsible for nuclear power plant operation but with offices which may be remote from the ~

plant site.

4.3 Plant MainEenance Staff - Plant personnel responsible for repair and modification of plant equipment.

4.4 Sample Sources - Those points in the system from which a sa.nple is drawn for analysis.

i 4.5 Station Management / Operating Staf f - On-site management responsible for overall station performance and plant personnel responsible for the day-to-day operation of a nuclear unit.

4.6 frended Chemistry Data - Chemistry data plotted vs time. Provides a rapid visual method of assessing plant chemistry.

The roles of corpor-ate management may include, periodic restatement of commitment to the operating policy, maintain"ing a long-term perspective of the plant operation, maintaining an awareness of the real and potential oper-ating problems as affected by plant chemistry, and assuring periodic review of the operating policy.

5.2 Station Management / Operating Staff: Responsibilities include un-derstanding the impact of the chemistry control on major component performance, availability, and expected life; understanding the chemistry control program and the management support for the pro-gram; and establishment of corrective action priorities.

5.3 Plant Chemistry Staff: Responsibilities include understanding the corporate management goals for the program implementation of the chemistry control program, timely data review to identify problems quickly, initiation of any required corrective actions, and making i any necessary changes in the chemistry monitoring requirements to

,,, improve the chemistry control program.

6 5.4 Plant Maintenar ce Staff: Responsibilities include prompt and ef fective repair of plant equipment required to maintain chemistry specifications.

5.5 Planning & Scheduling Staff - Responsibilities include timely issuance of corrective maintenance required to maintain chemistry within specifications.

6.0 SAMPLING AND MONITORING INSTRUCTIONS 6.1 A secondary chemistry monitoring program to maximize steam generator availability and operating 1.ife shall be carried out on the samples, parameters, and frequencies ' listed on Attachments 1, 2 and 3 accor-ding to the status mode of t he unit.

6.2 Sampling and analysis of the concerned parameters will be carried out using current approved procedures.

6.3 Analysis results shall be recorded on the Daily Clean Lab Water Report for Unit One.

If an out-of-spec condition is noted, request additional verification in the form of a confirmatory grab sample.

j 6.6 Any out-of-spec conditions or deleterious trends shall be promptly re-ported to the Chemistry and Environmental Supervisor or his assistant and also to the Shif t Supervisor. On a back shift, or in the absence of the Chemistry and Environmental Supervisor, the Shift Supervisor shall be promptly alerted of the findings by the Chemist.

i 6.7 The Chemistry and EnviroEmental Supervisor and/or the Shif t Supervi-sor shall proceed with a plan of corrective action to bring the parameter back into a normal value range. Typical corrective actions include:

6.7.1 Compare relults of confirmatory analyses to readings from continuous monitors.

6.7.2 Increase steam generator blowdown to maximum levels for the removal of specific impurities. (This can be done f during certain startup periods only.)

6.7.3 Isolate and identify sources of impurity ingress.

6.7.4 Compare results of various analyses for internal consis-tency.

6.7.5 Increase sample and analysis frequencies for short-term trending of critical chemistry parameters.

6.7.6 Refer to Attachments 4, 5 and 6 for corrective action of specific parameters.

6.8 All values from analyses and instrument readings should be archived for long-term trending and review.
