8. Offsite Dose Calculation Hanual Revisions-The affected pages for Revsion 87 to C-288 (ODCH) are included as httachaent-h to this report. The reasons for the changes are as follows-
1) Generic changes of an administrative nature-(D/Q)> {X/Q), {X/Q) , Q , gt etc. were changed to read:

D D/Q > X/Q X/Q , QDOT , and dt to reduce entry of D typographical and double usage of these symbols through various word processor limitations and to eliainate the need for hand entered symbols. These changes should improve the Quality Control of the ODCM in this area.

2) Where references were made to the Technical Specifications and Limits, the ODCM was updated to the wording of the current
       . Technical Specifications. Several typos concerning limits were corrected. These errors had been introduced by Rev 86 on a word processor where the proof reader missed the typos.
3) The only methodology change of Rev. 87 concerns Section 1.4 and Appendix -B. A limited analysis dose method may be used based on seven nuclides etc. Based on early 1986 effluent results, Iron-55 dose contribution indicated that a conservatism factor of 8.8 would not be sufficient to cover possible dose contribution from Iron-55. Since the original ODCM Appendix-B was not evaluated for Iron-55, and that Iron-55 results from Quarterly Composite Samples are not immediately availabe, twenty percent is now allocated to Iron-55 alone. This lowers the 8.8. factor of Section 1.4 to 8.6, which should provide more conservatism in estimating dose by the method precribed by this Section.
                                                             /
9. Solid Waste and Irradiated Fuel Shipments-No irradiated fuel'hipiaents were made froa the site.. Common Solid waste from ST. Lucie Units 1 and 2 were shipped jointly.

A summation of these shipments is given in Table 3.9 of this report.

18. Process Control Program Revisions-No revisions were made during the reporting period.

I FLORIDA POWER 6 LIGHT COMPANY ST. LUCIE PLANT SEMIANNUAL REPORT JULY li 1986 THROUGH DECEMBER UNITS 1 AND 2 TABLE 3.9 (CONT.) 3li 1986 SOLID WASTE SUPPLEMENT The total curie quantity and radionuclide composition of solid waste shipped from the St. Lucie Unit 1 & 2 are determined using a combination of qualitative and quantitive techniques. In general, the St. Lucie Plant follows the guidelines outlined in the Low Level Waste Licensing Branch Technical Position (BTP,) on Radioactive Waste Classification (5/ll/83) for these determinations. The most frequently used techniques for determining the total curie quantity in a package are the dose to curie methods and the (concentration) x (Volume or Mass) calculations. Where appropriate, engineering type activation analyses may be applied. Since each of the above methodologies involves to some extent qualitative parameters, the total curie quantity is considered to be an estimate. The composition of radionuclides in the waste is determined by both on-site analyses for principal gamma emitters and periodic off-site analyses for other radionuclides. The on-site analyses are performed either on a batch basis or on a routine basis using reasonably representative samples as appropriate for the waste type. Off-site analyses are used to establish scaling factors or other estimates for, radionuclides such 3H< 14C~ 99Tct 129I ~ TRU241pu< 242Cm< 63Ni z and Fe "Principal Radionuclides" refer to those radionuclides contained in the waste in concentrations greater than .Ol times the concentration of the nuclides listed in Table 1 or .Ol times the smallest concentration of the nuclides listed in Table 2 .of 10 CFR 61. "Type of Waste is generally specified as described in NUREG 0782, Draft Environment Impact Statement on 10 'CFR 61 "Licensing Requirements for Land Disposal .of Radioactive Waste".. "Type of Container" refers to the transport package. 24

LUCIE PLANT CHEMISTRY OPERATING PROCEDURE NOe C 200~ REVISION 7 OFFSITE DOSE CALCULATION MANUAL (ODCM) APPENDIX B Limited Aznlysis Dose Assessment for Liquid Radioactive Efftuents The radioactive liquid efftuents for the years 1978, 1979, aud 1980 axe evaIusted to determtne the dose ccntributicn of the zadi~de distributicn. This analysis was perforaad to dose calculation to a few selected zadicnuclides that ccatribute the na)ority of the dose provides a sisplifked aathod of determining conpliance with the dose limits of Ted',cal Specificaitcn 3.11.1.2. Tables B-1 and B-2 present the results of this evatustim. Table B-1 presents the fzacticn of the adult total body dose c~ributed by the na)or zadiouuclides. Table B-2 pzusents the sana data for the adult GI-LLI dose. The adult total body and whit GI-LIZ were detexmfned to,be the limiting doses based m an evaluaticn of all age groups (adult, teenager, child, and infant) and all orgms (boue, liver, kidneyf tung/ and GI-LLI). As the data in the tables shaw, the zadicnuclides Fe-59, Co-58, ~, ZtHi5, Cs-134, aud Cs-137 dminate the total body dose; the In,all but zadicuuclides, Fe-59, Co-58, Co-60, Zrr65, and Nb-95 domhate the GI-LLX dose. cne case (197Mish, GI-LLI dose) these zadicouclides ccntribute 90K or nate of the total dose. If fa: 1979 the fish snd she1lfish pathways aze conhined as is dane to determtne the total dose, 'the ccntrlbution from these nuclides is 848 of the total GIWLX dose. 2xxefoze, the dose cottmitttant due to zadioactive ttaterial in liquid efQuents can be zessorably estimated by 1imiting the dose ca1culation to the zadicnuclides, Fe-59$ Co 58f Zn-65, Nb-95, Cs-134, aud Cs-137,.which cumlatively cuatribute the rra)ority of the total Rse calculated by using all zadicnuclides detected. 'Ibis limited analysis dose assessnant method is a sinplified calculaticn that pzovides a zeascnable evalusticn of doses due to liquid zadicective efftuents and allows for an estimate of Fe-55 ccntribution to dose.

                                                                                       /

Tritium is mt inctuded in the limited analysis dose sssessaant for liquid releases because the potential dose resulting from nornal reactor releases is xagligible md is essentially independent of zadwaste system opezatim. The straunt af tritium zelesses snmally is about 300 curies. At St. Lucie, 3R Ci/yr zeleased to the Atlantic Ocean produces a ca1culated whole body Rse of 5 X 10 7 mrem/yr via the fish snd shelIfish pathways. This anaunts to less than 0.001X of the des~ objective dose of 3 mzem/yr. Furtherneze, the release of tritium is a functim of operating tina snd parer level snd is essentially unzeIated to zahraste system operatic.
