50-250 and 50-251 A
endix I Information Question 1
Clarify the inconsistencies in information concerning the represen-tative of onsite meteorological measurements, particularly low level wind speed and direction, and. vertical temperature gradient.
Answer 1
The South Dade meteorological system is more modern and has better recoverability than the Turkey Point meteorological system.
- However, as stated in our letter of January 27, 1977 (L-77-33), the meteoro-logical equipment at Turkey Point is adequate to meet Appendix I requirements.
Even though the November 15, 1976 study pointed out that the Turkey Point measurements are less precise than the South Dade measurements and the South Dade terrain is less obstructed, we have nevertheless concluded that the Turkey Point 'data are representative of the Turkey Point site.
Question 2
Discuss which available onsite meteorological measurements would provide the "best estimate" of atmosphere transport and diffusion characteristics for an interim Appendix I evaluation.
Answer 2
As discussed in the attached Appendix A, the South Dade meteorological measurements appear at. this time to give the "best estimate" of atmosphere transport and diffusion characteristics.
APPENDIX A A COMPARISON OP METEOROLOGICAL DATA COLLECTED AT TURKEY POINT AND SOUTH DADE NUCLEAR POWER PLANT SITES~
AUGUST 24'976 The original data provided in the report on decommissioning was further analyzed for periods when wind conditions were onshore at Turkey Point and South Dade (clockwise from NE to SSE).
Cross tabulations for the low level wind direction and wind speed as well as the atmospheric stability are given in Tables l-3, respectively.
Additionally, a correlation analysis was performed on the vertical temperature gradient.
(normalized to 100 m) as provided in the original report.
During on-shore flow conditions, a consistent one sector shift in wind direction identified in the original report in Section 4.1.4.3 remained evident:.
A post calibration of the Turkey Point wind direction equipment identified a'
24'eparture from accuracy in the same direction as the one sector shift.
Therefore, at least a portion of the one sector shift is probably attributable to instrument inaccuracy.
The wind speed cross tabulations indicate overall similarity between the two sites.
The stability, which is of greatest
- concern, shows relatively good correspondence.
Considering the oceanic influence, the rate of traverse of sea breeze conditions, and the displacement from the coast of both sites (Turkey Point 1/2 mile; South Dade 2 miles),
the cross tabulation is not at all unreasonable.
In fact, the disparity between levels at which the vertical temperature gradient (hT) were computed (Turkey Point 5.00 35.45 meters and South Dade 11.67 58.13 meters) and the narrow range of several stability classes may well have been the governing factors in the stability differences between the two sites indicated by Table 3.
The correlation coefficient of 100 meter hT's between the sites is.799.
We anticipate that a comparison of bT's collected from a single tower at the levels 5.00 m 35.45 m and 11.67 m 58.13 m,
normalized to 100 m, would not yield a significantly higher correlation coefficient.
The NRC's concern that the stability criteria may exhibit a time lag between the two sites due to coastal effects is not apparent from the evaluations presented.
A summary of onshore flow stability conditions was then generated by hour of the day.
Tables 4 and 5 present the frequency of stability class versus time of day for Turkey Point and South Dade, respectively.
There is a slight tendency for more stable conditions at Turkey Point during the Bay;
- however, the shadowing of the lower temperature sensor by the building complex reduces insolation considerably
- and, thus, thermal turbulence.

Question 4
Explain the difference between the level of wind measurements indicated in Item c(1) of the 1/27/77 submittal and those indicated in Table 2 of Attachment, C to the same submittal.
Answer 4
The information given in Item c(1) of the 1/27/77 submittal was taken from an earlier study.
Xt does not reflect the more precise efforts made to obtain the information given in Attachment C to the 1/27/77 submittal.
Thus, the sensor placement information in Table 2 of Attachment C is more appropriate for a comparison of Turkey Point and South Dade meteorological data.
Question 5
Explain how "All meteorological tower wind speeds are reduced to a
10 meter level by the Pasquill definition of the vertical lapse rate (see Table 1 of Attachment B)."
Answer 5
All meteorological tower wind speeds were reduced to a 10-meter level by the Pasquill definition of the vertical temperature lapse rate and the following wind speed power law:
10 meters n
10 h
h meters where u = wind speed (mph) h = 9.1 meter height (30 feet) or the 71.6 meter height (235 feet) if the 9.1 meter wind speed was missing or invalid n =.25 for Pasquill A, B, C, D or.50 for Pasquill E,
F and G
The above technique is desired by the U.
S. Nuclear Regulatory Commission (USNRC) for standardization purposes so that different sites can be compared on equal terms.
