The factor hs been set at 5 0.8 in Section 2.1.2.3.The nominal flow rates are 10 provided in Section 2.1.3.2.Provision for setting Radwaste Monitor set point concurrent with contamination of a dilution stream are provided in Section 2.1.2.2.Liquid Effluent Detectors Responses (Table 2-1)'t is not clear to what types of radiation (gamma, beta, or both)the detector responses provided in Table 2-1 are related.Liquid Effluent Detector 6 discussion provides this info.in Section 2.1.3.1'hat is the justification for considering only the isotopes listed in the tables?Are other isotopes ignored?Response of the detector 6 to liquid samples from appropriate waste streams is described in Section 2.1.3.1.Liquid Concentration
'o demonstrate that the Licensee's Technical Specification 3.11.1.1 is met, the surveillance requirements specify that the sampling and analysis program be implemented according to Table 4.11-1 of the RETS.According to the NRC Branch Technical Position, the Licensee should: Liquid Effluent Concentration will be calculated and compared to MPC in accordance with the equation of Section 2.2 for all effluent streams for all periods of release.This summation will therefore account for combined discharges to the same release point.12

Liquid pathways are not clearly identified for the dose calculation.
Section 2.5 addresses sample representativeness.
The results of sampling and analysis in accordance with Table 4.11-1 provide the concentration data used in Section 2.2.All efflluents are discharged via the same pathway.See figure 2-9 and Section 2.3 for discussion of the dose pathways to be included in dose calculation.

'he Licensee uses 1.7E-06 (sec/m3)for the highest calculated annual (X/Q), which is lower than 2.0E-06 (sec/m3)provided by the Licensee in Section 3.1.2.2 (p.7).Explain the discrepancy.
Section 3.2 identifies the 37 Dose Rate limits which apply.Changed X/Q to 2.0E-6 in 38, 39, Sections 3.2.1 and 3.2.2 to 31 be consistent with value used for setting alarm point (Section 3.1.2.2)which is also based on: dose rate at the Site Boundary.Plume Shine Parameters (Table 3-2)13'he Licensee has not provided a methodology to calculate the plume shine factors Bi and Vi.The methodology of calculation is provided in Section 3.4.1.45'he Licensee did not provide any data for Table 3-2.(The Licensee stated that"The values in this table will be provided at a later time".)The values have been provided in Table 3-2.62 Tables 3-4 to 3-21 Uranium Fuel Cycle 15 to 32 35 Provide equations in the ODCM for the parameters calculated in the tables.'he Licensee stated that fish consumption and shoreline sediment are the pathways used for liquid dose calculation.
However, the drinking water pathway is not considered.
Also, the methodology to calculate doses from shoreline sediment is not provided in the ODCM.The equations for calculating the parameters for Tables 3-4 to 3-6 are in Section 3.4.3 and those for Tables 3-7 to 3.21 are in Section 3.4.4.The drinking water pathway is not significant.
Methodology for calculating doses from shoreline sediment is provided in Section 4.1.47-58 90, 91
~Sub'ect Rev.0 Pa e Number 35 Rev.0 Comments No methodology is provided to estimate the direct radiation.
Rev.1~Res ouse The methodology using environmental TLD's is given in Section 4.3.Rev.1~b 92 Environmental Honi toring Program 36 41-43'he equation given for factor R is incorrect:
some typographic errors may have been committed.
'n Table 5.1 for sampling locations, the nature of the locations (such as on-site, control, or indicator) is not clearly specified for each location.Since Nine Mile Point Units 1 and 2 and the Fitzpatrick plant are located at the same site, the envrionmental sample locations, by agreement between the respective licensees, are supposed to be identical.
However, numerous differences are found between the sample locations of Nine Mile Point Unit 2 and the locations provided in the FitzPatrick ODCM (Rev.2 dated June 25, 1985).It appears that Nine Mile Point Unit 2 has a complete list of the most up-to-date information on sample locations.
However, the differences may reflect lack of coordination between the respective licensees on environmental sample programs.The differences in the equation given and the equations of Sections C-3 and C-4 of Reg.Guide 1.109 are identified in Section 4.4.(X/Q is in units of sec/m3).The equation is correct.No on-si te moni tori ng locations are required.Control locations are those located at map locations 30, 31, 38, 43, 47, 54, 55;all easily distinguished by distance and direction.
Unit 1 and Unit 2 ODCH's now indicate identical locations; the JAF recent revision should be the same.94 98-100

'he Licensee did not provide a section to describe the methodology for monthly liquid dose projection per the Licensee's RETS 3.11.1.3.Section 2.6 was provided 16 to address TS 3.11.1.3.Note that it is expected the liquid radwaste system will be fully utilized at all times, thus negating the need to make such a projection, except in unusual circumstances.
Liquid and Gaseous Effluent Flow Oiagrams'he NRC Branch Technical Position as issued in 1979 specifies needs for the licensees to provide effluent flow diagrams to clarify and explain the operability of the radwaste treatment systems.The Branch Technical Position states: "Provide a flow diagram(s) defining the treatment paths and the com-ponents of the radioactive liquid, gaseous and solid waste manage-ment systems that are to be main-tained and used, pursuant to 10CFR50.36a, to meet Technical Specifications 3.11.1.3, 3.11.2.4 and 3.11.3.1.Subcomponents of packaged equipment can be identi-fied by a list.For operating reactors whose construction permit applications were filed prior to January 2, 1971, the flow diagram(s) shall be consistent with the information provided in confor-mance with Section V.B.1 of Appendix I to 10CFR50.For OL applications whose construction permits were filed after January 2, 1971, the flow diagram(s) shall be consistent with the information provided in Chapter ll of the Final Safety Analysis Report (FSAR)or amendments thereto." Figures 2-1, 2-2 and 2-3 define the Low Conduc-tivity Liquid Waste System.Figures 2-4, 2-5 and 2-6 define the High Conductivity Liquid Waste System.Figures 2-7 and 2-&define the Regenerant Waste System.Sol i di f i cati on of waste is addressed in the Process Control Program, separately submitted (see TS 3.11.3).The figures provided are from the FSAR, Chapter 11.20, 21, 22 23, 24, 25 26, 27 I
~Sob ect Liquid and Gaseous Effluent Flow Diagram (Cont.)Estimation of I-133 Rev.0 Pa e Number Rev.0 Comments The flow diagrams should also contain information on the effluent monitoring instrumentation regarding the setpoint calculation.
Thus, the information as required by the Branch Technical Position includes: "The instrumentation for each alarm and trip setpoint, including radiation monitoring and sampling systems and effluent control features, should be identified by reference to the FSAR (or Final Hazard Summary).This information should be consis-tent with the recommendations of Section I of Standard Review Plan 11.5, NUREG-75/087 (Revision 1)." The licensee did not provide a method to estimate the release of I-133.On estimating the radio-activity of I-133, the NRC staff has specific guidance as follows: "Under appropriate conditions, the l-133 contribution could be impor-tant to the Part 20 dose rates and to the Appendix I doses.Therefore, Specifications 3/4.11.2.1 and 3/4.11.2.3 should be written as shown in the enclosures.
Rev.1~Res oose ODCM Figure 2-9 iden-tifiess the Service Water monitors (RE 146A and RE 146B), the Cooling Tower Blowdown monitor (RE157), and the Liquid Radwaste Effluent monitor (RE 206).Figure 3-5 iden-tifies the Gaseous Effluent pathways.Figure 3-6 provides a block diagram of the stack monitor (RE 170).The vent monitor (RE 180)is essentially identical.

~Sub'ect Estimation of I-133 (Cont.)Rev.0 Pa e Number Rev.0 Comments These speci f i cati ons wi 1 1 not explicitly require sampling and analysis to determine the I-133 releases.Therefore, Table 4.11-2 need not specify I-133.Conversely, the Specifications will require accounting for I-133 and the method for so doing must be detailed in the ODCM.Acceptable methods will be addressed in NUREG-0133, Rev.l.Rev.1~Res ouse Rev.1 Pa e Number Acceptable approaches to estimating I-133 releases are as follows: 1.Convert the samples for I-133 (as well as I-131)and assume a constant release rate so buildup is proportional to[1-exp(-At)]/A.2.Periodically take short-period samples to determine the ratio of I-131 to I-133 activity.Then, use this ratio to estimate I-133 re-leases based on measurements of I-131 releases.3.In special cases, where a plant lacks capability for measuring I-133, assume that the I-133 activity release is 4 times the I-131 acti vi ty." Method 2 or Method 3 will be used depending on analytical results obtained.Method 1 is ambiguous; we do not plan to use it.59 t
