DearMr.Miraglia:

TheBureauofRadiological HealthstaffhavereviewedtheDraftEnvironmental Statement (DES)relatedtotheoperation ofSt.LuciePlantUnitNo.2,NUREG-0842, datedOctober1981.TheproposedactioncoveredbythisDESisissuanceofanoperating licensetotheFloridaPowerandLightCompanyforthestartupandoperation ofSt.Lucie,UnitNo.2.CommentsontheDraftEnvironmental Statement

-Construction PhasewereprovidedbythisagencyinMarch1974(Appendix A-10,pageB-121)priortoissuanceoftheconstruction permitinMay1974.WenotethatasofAugust1981,theconstruction ofUnitNo.2wasapproximately 80percentcomplete.

Mr.FrankJ.Miraglia, NRC-Page23.Discussion inSection5.10.4ontheenvironmental impactofpostulated radiological accidents isconsidered tobeanadequateassessment oftheradiation exposurepathwaysandthedoseandhealthimpactsofatmospheric releases.

Wewillforegocommentsontheemergency preparedness section,sincewerealizethattheprocessofgrantinganoperating licensetothefacilitywillincludeanadequatereviewofemergency plans(FEMA-NRC Memorandum ofUnderstanding, RegionalRAC'scriteriainNUREG-0654).

Wehaverepresentation ontheRAC'swhoseevaluation relativetotheSt.LuciePlantwillspeakforthisAgency.Itisnotedthatanemergency operation facility(EOF)willbeconstructed (Section5.13.2)whichwillbeafocalpointfordirecting responses andcoordinating activities tomitigatetheconsequences ofaccidents.

4.Theradiological monitoring program,aspresented inSection5.10.3.4andsummarized inTable5.5,appearstoprovideadequatesamplingfrequency inexpectedcritical'exposure pathways.

Theanalysesforspecificradio-nuclidesareconsidered s'ufficiently inclusive to(1)measuretheextentofemissions fromthe"plant,and(2)verifythatsuchemissions meetapplicable radiation protection standards.

In,view,ofsomeofthemonitoring problemsthatwereidentified duringtheThreeMileIslandUnit'2accident, wesuggestthattheprogrammightbemodifiedtoaddress'inpaiticular theproblemsofmonitoring radiohalogens (especially radioiodines) inthepresenceofradionoble gases.Thiscouldbeaccomplished by,reference toFEMA-REP-2, adocumentoninstrumentation systemspreparedwithconsiderable inputfromNRC.5.Section5.11andAppendixIofthisDEScontainadescription oftheenvironmental impactoftheUraniumFuelCycle(UFC).Theenvironmental effects,prese'nted areareasonable assessment ofthepopulati.on dosecom-mitmentandthehealtheffectsassociated withreleaseofradon-222 fromtheUFC.ThereisnomentioninAppendixIoftheDESinEPA'sUraniumFuelCyclestandard, aspromulgated in40CFR190,andcitedinSection5.10.1,paragraph 1,onpage5-14.Astatement shouldbeincludedintheAppendixthattheenvironmental dosecommitment fromallfuelcycleoper-ationsmeetstheannualdoselimitsestablished byEPA.-Thankyoufortheopportunity toreviewandcommentonthisDraftEnvironmental Statement.
