CHANGES TO THE FSAR - REVISION 6.
The attached page changes of the Palisades FSAR have been reviewed and approved in accordance with 10 CFR 50.59~.
The changes are noted by a bar in the.right-hand margin on pages 11-.4 and 11-6.
The new pages dated ll/14/79 should "Qe inserted in ;your copy of the FSAR and are replacements.

The controlled c
liquid waste from sampling the primary coo ant for chemical and radiochemical analysis.
Liquid w te from the radio-chemistry lab drain tank is disc arged to the clean waste receiver tanks.
The clean waste receiver s provide a temporary storage to allow for natural decay f the collected liquid waste
. and sampling of liquid wa e activity. Liquid waste from the receiver tanks is di charged through the clean waste filter to remove insol le particulates and through the radwaste demineralize to remove soluble ions.
Under.normal condit ons, the effluent from the clean waste demineralizers pa&ses to the clean waste holdup tank or to the fourth clea~A:raste receiver tank and then to the rad-waste evaporat2/.
The evaporator has the capability to process both eontinuously as well as in a batch mode.
When operaty{g in the batch mode, transferring to the fourth clejli waste receiver tank allows larger batch sizes to Je processed.
The radwaste evaporator removes all radi-0active isotopes except tritium and separates
- the borlc acid from the processed waste and sends.it to the e;{aporator concentrate tank.
The boric acid is then pumped through a filter and into the recycled boric acid st rage tank where it is available to the chemical and
- v. lume control s.ystem for regulating the primary coolant.
f the boric acid is not needed, it is' sent to the solid waste station where it is prepared for offsite disposal.
The distillate from the radwaste evaporator is normally processed through a polishing demineralizer to further reduce the boron and, radioactivity concentrations and then sent to the primary system makeup storage tank where it is stored until used by the chemical and volume control system in making up the primary coolant. If volumes become.
excessive under abnormal operating conditions, it may be necessary to send the distillate from the evaporator to the treated waste monitor tanks for sampling and then to either the clean waste receiver tanks for further decay or to the circulating waster discharge for dilution and release to the environment after reduction to levels that are as low as practicable.
The maximum anticipated annual quantity of clean liquid waste of significant activity to be processed through the liquid waste system is 724,300 gallons.
As shown in
.Table 11-2, 586,600 gallons or 81% of the total quantity 11-4 Rev 12/15/73

>Liquid from the dirty waste drain tank is processed through the dirty waste filter to the miscellaneous waste holdup tanks for temporary storage before pumping to a radwaste evaporator identical to that in the clean waste. system.
The distillate from the evaporator is sent to the miscel-laneous waste distillate tank and then through two demin-eralizers to the utility water storage tank for reuse in the plant. If volumes become excessive under abnormal operating conditions, the output from the d.emineralizers
- can be sent to the filtered waste monitor tank for sampling and then be either discharged to* the environment or sent to
- the clean waste receiver tanks for f'urther decay.
The boric acid concentrate from the radwaste evaporator is sent to the evaporator concentrate tank.. The concentrate is normally sent to the solid waste station for solidifi-cation and offsite disposal, but the capability to recycle the boric acid for use in making up the primary coolant water is also present.
As with the clean waste system, the demineralizers are as-sumed to reduce the concentration of all nuclides by a factor of 10 except for noble gases and tritium.
The de3ontamination facto~ of the evaporator is assumed to be 10 for iodine and 10 for all other isotopes except tritium.
Table 11-3 summarizes the performance of the dirty waste system (by isotope) under design operating conditions of 13 defective f'uel.
No credit has been assumed for any*
decay in the miscellaneous waste holdup tanks. Still, the effluent from the demineralizers which will be recycled.
to the utility water storage tank is of negligible activ-ity as the table shows.
Laundry Waste System All liquid effluent from on-site laundry is collected in the laundry drain tank.
The liquid is sampled at the tank and then filtered.
The liquid is processed through the 11-6 Rev 12/15/73
