liufmum Reactor Coalitnt Ouggn and Chloride and Flupride Concentration
[gr Power O gna_tig.a J
Specifig tion:
l 1.
The concentration of oxygen in the reactor coolant shall not exceed 0.1 ppm.
2.
The concentration of chloride and-oM1uoMde in the reactor coolant shall not exceed 0.15 ppm each.
3.
The concentration of fluoride in the reactor.cochnt shall not' ektsed 0.15 ppm.
4.
If the oxygen, concent-rat 4en-ano-lhe chloride or fluoride concentrations of in the reactor coolant simultaneouMy exceed the limits given in 1)', and 2) or 3) repect4vMy, corrective action is to be taken immediately to return the system to within normal operation specifications.
If the normal operational limits are not achieved within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> tif discovery of thdlout--

?
Basis:
By maintaining the oxygen, chloride and fluoride concentration in the reactor l+
coolant within the limits as specified by -E 1), 2) and 3), the functional
~
integrity of the materials of the Reactor Coolant System is assured under all aperating conditions.("
1, if these limits are exceeded, measures can be taken to cor rect the condition, e.g., replacement of ion exchange resin or adjustment of the hydrogen concentra-tion in the volume control tank", and further because of the time-dependent nature of any adverse effects arising from oxygen, chloride and flucride concon-tration in excess of the limits, it is unnecessary to shut down immediately since the condition can be corrected.
Thus t'no period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for corrective action to restore the concentrations within the limits has been established.
