SUBJECT:
RAC!lASTE SYSTEM PAP.A. ETERS FOR '.:?iP-7.
P.EFERE!'CE: !'erorandum, J. F. Don ~ hue to D. !!. f reeller, ACRS, October 4,1982 The referenced menorandun points out differences in raduaste syston parareters between those used in the evaluation of WP-7. and those used to evaluate three otber plants.
In one case, the difference was due to a typocraphical error.
In each of the other cases, differences are attributable to variables in systen desian and use of specific cornonents, as well as to acceptable variations in assur.ptions as to the fractions of nrocessed fluids to be released.
Systen parareters for P'.ms are detailed in t't:P.EG-0016, P.ev.1, January 197G.
Dif ferences pointed out in the acrorandum are discussed belo.4, in accordance with your request of Cctober 14, 1962.

Kr Adsorptio_n Coefficient 105 1.85x10 Kr lioldup Tine 1.8 0
Xe Adsorption Coef ficient 2410 3.0x10 Xe !!aldup Tire 42.6 P.ESPO!!SE:
There was a typographical error in tre LaSalle SER for the adsn..-
tion coef ficients for Xe and Kr. The correct values should be Xr: 18.5 cn /cm 3
(at an operatinq tencerature of 77*F and a dew coint of 45'F) and Xe: 330 cn /qn (at an operating temnerature of 77*F and a dew point of 45*F).
The di fference between the corrected values and those of !!!!P-2 lies in the design of the LaSalle systen, which operates with an anhient terperature charcoal hed, while the @sien of the !WP-2 svsten calls for a refriqerated charcoal bed eneratino at a nrinal OT and a -20*F deu point. The refrigerated charcoal bed Provides for 3 sub-stantially loncer boldup tire for Xe and l'.r.
See Mt! PEG-0016, rev.1, Janmry 1973 for discussion of parareter values.

Fren T1ble 1-4 of HUREG-0016, the staff's volumes attributabic to this systen total only 600 gpd, consisting of 500 god of lab drains and 100 gpd of chenical lab waste. Since the apolicant predicts a substantial portion of the input to be due to deter-cents and decontanination solutions, and plans to process detert!cnt laundry wastes in the sane systen, we assigned a 0F of 100 to the systen evaporator in accordance with Table 1-5 of HUREG-0016. 'n!P-2 does not reqenerate rad-waste deninerali:ers and therefore has no reqenerant solution inouts
(~ 3,400 cod) as in the cases of LaSalle, Hatch-2, and Zirrwr.
'!'IP-2, LaSalle,
and Zineer each predict the discharge of 10% of processed solutions and the recycle of 007..
Hatch-2 plans to discharne 10C", of processed solutions.
Also, the LaSalle systen values represent tuo units.
