QUESTION E451.8 (Section 2.3) ggQQ MYeh%b_R Five years (1972-1976) of data record have been submitted in joint frequency distribution form. Regulatory Guide 4.2 (Revision 2) states that the data set should include the most recent one year period for an operating license appli-cation. Provide the joint frequency distributions of wind direction and wind speed by atmospheric stability class (as defined by vertical temperature difference) for the most recent annual cycle of meteorological data (1980 or later) for all levels of wind and vertical temperature difference measurements based'on data from tower 1 and. if available, from the other towers. The data year selected should represent conditions which were unobstructed by temporary terrain modifications. Provide the frequency (hours and percent) of calms (as defined in Question E451.7 from Regulatory Guide 1.111) by stability class and do not include calms in the joint frequency distribution tables by wind direction.

RESPONSE

The requested information was transmitted to the NRC by letter from J. S. Kemper to A. Schwencer dated September 1, 1982. One copy of a magnetic tape of hourly data and five copies of joint frequency distributions were included with the letter. As required by Regulatory Guide 1.70, Section 2.3.3, this material represented the most recent one-year period of record for 1980 currently available.

The magnetic tape was resubmitted on October 13, 1983, by letter from J. S. Kemper to A. Schwencer in order to correct a deficiency in the original tape.

The joint frequency distributions submitted with the September 1, 1982 letter are unaffected.

In addition, one (1) copy of a magnetic tape containing hour-by-hour data and five (5) copies of the joint frequency distributions for the 1980 year on a " composite" system basis were included with the October 13, 1983 letter. The

" composite" system includes all of the primary tower (Tower No. 1) data, but uses secondary tower (Tower No. 2) wind speed and direction data from the same MSL elevation where Tower No. I data are missing. The justification for this substitution has been established by the Applicant and is presented in FSAR Section 2.3.2.1.1.2 and Table 2.3.2-30.

QUESTION 451.9 (Section 2.3.2)

?? ,

Five years (1972-1976) of data record have been submitted in joint frequency distribution form and hour-by-hour on magnetic tape. Regulatory Guide 1.70 (Revision-3) states that the data set should include the most recent one year period for an operating license application.

(1) Provide the joint frequency distributions of wind direction and wind speed by atmospheric stability class (as defined by vertical temperature difference) for the most recent annual cycle of meteorological data (1980 or later) for all levels of wind and vertical temperature difference measurements based on data from Weather Station No. I and, if available, from the other stations. The data selected should represent conditions which were unobstructed by temporary terrain modifications. Provide the frequency (hours and percent) of calms (as defined in Question 451.8 from Regulatory Guide 1.111) by stability class and do not include calms in the joint frequency distribution tables by wind direction.

(2) Provide a magnetic tape containing hour-by-hour

-data for the same annual cycle as in (1) above.

The data on the tape should be compiled in the NRC standard format for meteorological data as described in Appendix A of SRP 2.3.3 in NUREG-0800, Revision 2, July, 1981.

RESPONSE

Both items 1 and 2 were transmitted to the NRC by letter from J. S. Kemper to A. Schwencer dated September 1, 1982.

One copy of the magnetic tape and five copies of the joint frequency distributions were included with the letter. As

( requircd by Regulatory Guide 1.70, Section 2.3.3, this j material represented the most recent one-year period of

record for 1980 currently available.
