REACTOR COOLANT SYSTEM No: O-CY-2310 Rev: 16 SPECIFICATIONS AND FREQUENCIES Page 4 of 25 1.0 PURPOSE 1.1 This procedure establishes the requirements for the sampling, analysis and control of the Reactor Coolant System.
1.2 This procedure applies to the Chemistry control of the Reactor Coolant and Residual Heat Removal Systems.
2.0 PRECAUTIONS AND LIMITATIONS 2.1 Precautions and Limitations 2.1.1 The frequency and specifications for tests other than those required by Technical Specifications or the SPDES permit are recommended by Chemistry Management. The frequency of these tests may be altered at the discretion of Chemistry Management. Analyses with associated NSSS vendor requirements shall be evaluated prior to being altered.
2.1.2 For parameters that do not have a defined frequency or specification Chemistry Management will assign a frequency as dictated by plant conditions or historical trend.
2.1.3 Initially, laboratory analytical results are interpreted by the Watch Chemist or by the Watch Nuclear Plant Operator during their tours.
Abnormal trends in the chemistry data either obtained or observed are evaluated by the Chemistry Technician given the status of that system at that time. Any significant abnormality or trend, as well as, out of specification or out of control band chemistry parameter shall be brought to the attention of the Shift Manager, Control Room Supervisor, and Chemistry Management.
2.1.4 Refer to Reference 5.3.4 for Dose Equivalent Iodine (DEI) and Dose Equivalent Xenon (DEX) and associated required actions for radiochemical analyses of RCS.
2.1.5 Prior to entering Mode 1, RCS aHemperature pH shall be greater than 6.9.
REACTOR COOLANT SYSTEM No: O-CY-2310 Rev: 16 SPECIFICATIONS AND FREQUENCIES Page 5 of 25 2.1.6 The process of reviewing chemistry data that is NOT within chemistry specifications is flowcharted in Attachment 1, Chemistry Data Review Flowchart.
2.1.7, Reactor Coolant Boron/Lithium Specifications, is used as directed in Attachment 3. Values for lithium limits other than those listed should be verified by use of the Chemistry database. Documentation for these calculations is found in the procedure basis file.
2.1.8 The critical procedures and sample points for monitoring the inhibition of steam generator degradation, as required by Plant Technical Specifications, are located in the Primary Strategic Water Chemistry Plan.
2.1.9 Data consistency checks may be performed using Chemworks Primary pH Calculator OR Smart Chemworks ensuring that the data set has been uploaded at the time of verification.
2.1.10 IF lithium is within specification listed in Attachment 7 for xenon equilibrium full power operation THEN at-temperature pH is within control and greater than 7.0.
