/k INTRODUCTION The following summary has been prepared as a supplement to the Final Report dated 1 September 1967 which discussed the meteorological conditions at the Rancho Seco site. The summary is based on a reduction and analysis of wind data at the site for the period from September 1967 through January 1968. Copies of these data, reduced at three-hourly intervals, have been furnished to Bechtel Corporation.
In addition to the data recorded at the site, routine airport observa-tions at Stockton were collected for the same period for comparison with concurrent data at the site. Stockton data were also used to obtain frequencies of occurrence of various diffusion categories at Stockton for the period when wind records were available at the site.
Purpose of the summary has been to utilize the site data recorded since 1 September 1967 to update the earlier report and to definitize the appropriate diffusion model criteria on the basis of all currently available data.

SUMMARY
OF RESULTS
}
1.
Wind speed uccurrences for the site, Sacramento and Stockton are shown on the attached sheet. The differences between Stockton (SCK) and Sacra-mento (SAC) are attributable to height of the instrument (Stockton is 20 feet; Sacramento, 77 feet). Poor response of the instruments is shown at the low speeds by flat curves at velocities below 3 mph.
The site (53 feet) is intermediate between Sacramento and Stockton in the important range of 5 mph and less. The response of the instrument to low speeds is somewhat better. Some of this is due to the measure-ments being hourly wind averages rather than five-minute averages.
A second attached sheet shows a comparison between Stockton data and more recent Sacramento data taken after the observing location had been moved to a height of 20 feet. The two curves are brought more nearly into coincidence if corresponding heights are compared. The Sacramento data are from a relatively short period of record and should not be used in preference to the long-period Stockton data.
4 2.
Over the period of measurement record at the site, there were only two hours with calm winds recorded for the hour. Neither of these occurred with an F or G category. Thus, the worst case of calm winds for a two-hour period with moderately stable conditions did not occur.
3.
Diffusion categories have been listed on the attached sheet in terms of increasing dilution. The list refers to short releases and does not take account of the increased dilution for the F and G categories which arises from hourly releases. The values for the site have been esti-mated by decreasing the wind speed at SAC to correspond to a 53-foot height and by increasing the wind speed at SCK to adjust the 20-foot values to a higher level.
4.
On the basis of this tabic, I would recommend the use of category F and 2. 0 m/s for the SMUD site. More than 80 per cent of the expected diffusion conditions at the site will show better dispersion than repre-sented by these values. The selection of these values is thereby in accordance with the guidelines laid down by TID-14844. The wind speed of interest has been assumed to be the 53-foot level which should corres-pond closely to the cloud transport speed for a cloud 100 feet deep released from the site. If the cloud is released initially with this depth, there is no reason to consider a wind speed representative of a lower level for the purposes of obtaining realistic diffusion estimates.
5.
The conservative aspects of this selection can be expressed as:
a.
Conditions corresponding to F and 2. 0 m/s (or worse) occur only 15 per cent of the time at Sacramento and are estimated at less than 20 per cent at the site.
2 Amendment 2
~
f f
b.
A uni-directional wind has been assumed.
c.
No account has been taken of a meandering effluent cloud. Disper-sion data used in the calculations correspond to a 5 to 15 minute release period. An additional dilution factor of 1. 5 to 2 can be expected to result from two-hourly releases and the associated meandering under moderately stable conditions.
d.
Published experimental data have indicated that F and 1 m/s cal-culations tend to underestimate the dispersion for moderately stable conditions, even for short-term releases.
Transport wind speeds associated with a volume source resulting e.
from a hypothetical accident should move with a wind speed charac-teristic of a higher level than 53 feet. The values measured at 53 feet should represent a conservative estimate of the appropriate wind speed to use for diffusion calculations.
