_Pa_g_e Coment F.D-12 In two locations, the sigma sign is missing.

In the equation, the division sign is not clear; it resembles a plus sign.

2.0-17 The division sign resem W a plus sign.

2.0-19 Add the units (mrem /hr ,: . uCi/m ) to the heading of Table 21-1.

2.0-21 Add the correct reference for the bio-accumulation factors for silver.

3.0-2 A line of text has been omitted at the top of page 3.0-2. " monitor setpoints.

That is, setpoint adjustments are not" 3.0-4 The top line on page 3.0-4 duplicates the last line on page 3.0-3.

3.0-4 The parameter (X/Q) is defined to be "the highest annual relative concentration

' atthesiteboundaryinanysecgor",with a numerical value of 2.65 x 10- sec/m3 at the exclusion area boundary (901m) in the northwest sector. Staff calculations indicate i 8.7x10-gnannualaverageX/Qvalueof sec/m3 in the northwest sector 1 at a distance of 901m. Slightly higher (10-15%) values are calculated in the southeast and south sectors for the same exclusion area boundary distance.

Provide ju 2.65x10-gtificationfortheuseof sec/m3 as the " highest annual relative concentration at the site boundary," considering specifically the appropriateness of the assumption of

, straight-line airflow without modifica-tion for spatial and temporal variations l

in trajectories.

3.0-8 In the RETS, in Technical Specifications and 3.11.2.1 and 4.11.2.1.2, I-133 is included

throughout with I-131, tritium and all radionuclides i

in particulate form with half-lives l greater than 8 days. 1-133 must be i

included in the ODCM Section 3.2 and correspondingly throughout the ODCM.

l - . _ _ _ - .

Page Coment 3.0-12 Numerical val -8 sec/m3

.a_n_d,4.4 x 10~y ~gf are 9.9 x 10 for presented X/Q' and D7iT', respectively, on page 3.0-12, with a cross r.gf.grence to Table 3.2-4. The value for X/Q' apparently was calculated at a distance of 8 km in the northwest sector, and this___

value is the maximum of all the X/Q values presented in Table 3.2-4.

However, the corresponding D3 at that location is exceeded by D7Q values in the west-northwest sector and in the northwest sector at 6.4 km. Provide justificagonfortheuseof 2

4.4 x 10- m as the value for D/Q' to be assumed "for other pathways and non-tritium nuclides" (as described on page 3.0-12).

3.0-46 Ge?erally, the X/Q and D/Q values presented in Table 3.2-4 (page 3.0-46) are in reasonable agreement $30%) with the values calcu-lated by the staff. However, some signi-ficant differences (ogr a factor of 3) are noted in several D/Q values. For example, the staff gas 2calculated a value of 8.3 x 10-i m in the east sector at a distance of 5 g @g compared to the value of 2.2 x 10-1 m presented in the table. Similar' discrepanci'es 'are noted for the east-northeast sector at 5.5 km and for the west-northwest sector at 5 4 km. Provide corroboration that the D/Q values presented in Table 3.2-4 accuratel reflect calculations.

Also, provide and D7U values for site boundary distances.

3.0-51 The atmospheric dispersion model described in general in Section 3.3 (Page 3.0-51) is simple enough to be fully described in two pages.

Cross-referencing to tables and sections in the FSAR is cumbersome, and could result in inconsistencies if the FSAR is amended without also amending the ODCM.

l l

In Section 3.3 of the ODCM, provide a complete description of the atmospheric dispersion model used for calculation of al average relative concentration X/Q and relative deposition ) values presented in the ODCM. Also, provide a description of the meteorological data used in the dispersion model (i.e., period of record, heights of measurement, and atmospheric stability indicator).

4.0-5 Show on these figures the location and 4.0-6 identity of the effluent radiation 4.0-7 monitors, i.e., the liquid radwaste discharge line monitor, the cooling tower blowdown effluent line monitor, the filtration, recirculation, and ventilation system noble gas monitor, the south plant vent noble gas monitor, and the north plant vent noble gas monitor.

4.0-17 It is recommended that this section be revised to state that, in the event that the annual land use census or other information should indicate that individual members of the public may be inside the site boundary more than a few hours each year, doses to such members of the public shall be calculated according to the methods of Sections 2.2 and 3.2.

4.0-18 We do not object to the elimination of the integrated population dose calculation.

5.0-3 In accordance with the RETS, samples for radiciodines and for particulates should be collected at the same locations; thus station IFl should be included in Table 5.1-1, section I.(b) as an iodine sampling station.

3.0-46 In accordance with the RETS and with 5.0-2 ODCM Table 3.2-4 ("The real receptor 5.0-3 with the highest exposure is an infant consuming the milk of a cow pastured at 4.9 miles in the W sector."), one sampling station collecting particulates and iodines should be located in the W sector at about 4.9 miles. At the time of the site visit, i

?

a list of sampling stations was provided the NRC/NRR/RAB representive; this list included a milk sampling station identified as 13E3, 4.9 miles W of vent, local fann. Such a sampling location 13E3 also appeared on Figure 6.1-2 of the HCGS ER0L. A sampling station in the vicinity of 13E3 is needed.

5.0-6 In Table 5.1-1, provide a legible sampling station identifer for the station at 7.4 miles NNE of the vent.

5.0-7 The infonnation on these pages of Table 5.0-8 5.1-1 should be put in the correct order; this involves both the page number and the designation "Page 6 of 9" and "Page 7 of 9."

5.0-7 In section VI.(a) correct the typo in the note on I-131 analysis.

5.0-8 In Table 5.1-1, section IV.(c), " gamma isotopic analysis on quarterly composite" must be changed to " gamma isotopic analysis on monthly composite."

5.0-11 Provide clear Figures 5.1-1 and 5.0-12 5.1-2. These maps are illegible.

5.0-11 Sampling stations 451 and 6S1 are shown on Figure 5.1-1; identify in Table 5.1-1 what samples will be taken at these stations.

5.0-11 In Figure 5.1-1, in sector 6, one of the two sampling station identifiers is illegible.
