i BASES J.
Condensate Demineralizers i
The criteria of the resin monitoring program and the resin replacement' program have been established to protect the reactor from high chloride level should'a seawater leak occur in the main condenser. Should a j
seawater leak occur when a resin has 5 pounds of capacity remaining,' this l
criteria will' allow a sufficient buffer for an orderly plant shutdown.
Therefore, the resin must be replaced before the calculated unused capacity of the resin reaches 5 pounds'of chloride ion.
The resin depletion can be calculated using the measured salt-splitti'ng capacity, the~ flow through the bed, and the average influent conductivity.
Based on this result, a depletion can be calculated which will assure a 5 pound chloride ion exchange reserve. Replacement prior to this level.
l of depletion will assure a sufficient ion exchange reserve for removal of j
chloride from the. condensate system.
These factors form the basis for the frequency of sampling, analyzing,.
calculation and logging surveillance requirements. A yearly or once per replacement sampling frequency will be sufficient to verify supplier resin specifications. As conductivity increases, the calculation and l-logging will be increased to a weekly basis and ultimately. on a daily-basis when and if influent conductivity reaches 0.3 umho/cm or greater.
K.
Mechanical Condenser Vacuum Pumo l
The purpose of selecting the mechanical condenser vacuum pump line-is to limit the release of activity from the main condenser in.the unlikely' event of a control rod drop accident. During the postulated accident, i
fission products would be transported from the reactor to the main steam lines to the main condenser. The fission product radioactivity would be-sensed by the main steamline radioactivity monitors and isolation would be initiated.
