Dear Hr. Rhode:
Slangier Subject; Nine Hile Point 2
OL EnvironmentaV'RtView - Requests for Additional Information l<e have completed our initial review of the mete(orology, air quality, and-'adioactive waste systems sections (ESRP Sections 2.7, 2.9, 3.5, 5.3 3.1 and 6.8) in the Nine Hile Point 2 Environmental Report and have identified additional information required for our review in Enclosure 1,
lie have also completed our initial review of the radiological assessment sections in the Environmental Report for Nine Hile Point 2 and have identified additional information required for our review in that area in Enclosure 2.
Additional requests for information concerning the Environmental Report will be transmitted to you as we complete our reviews of the remaining sections.
Me are taking this approach in order to allow the maximum time for you to respond to our questions.
Consistent with the licensing review schedule for Nine Hile Point 2 responses to these requests for additional information should be submitted as changes to the FSAR by October 21, 1983.
If you have any questions concerning the enclosed requests for additional information please call the licensing project manage,r,,
Hary F. H~aghey, at (301) 492-7897.
Sincerely,

2 Meteorol ogi cal Data E451. 16 (a) 2.7.4 NUREG-0555 2.3 Submit for accident consequence assessments one complete rep-resentative year (8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br />) of hour-by-hour meteorological data (wind speed, wind direction, stability, and precipitation) for a ground level release.
Include data substitutions for all missing periods.
a)
Transmit the data on magnetic tape in the recommended SRP 2.3.3 Appendix A format.
b)
Include a description of the method used to substitute for the mi ssing data.
E451. 16(b) 2.7.4 NUREG-0555 5.3.3.1 Submit at least one recent representative annual cycle of meteorological data on magnetic tape in the recanmended format with at least 90$ joint data recovery for the essential cool-ing tower modeling input parameters (wind speed 61(m), wind direction 61(m), stability 61-9(m), temperature 9(m),
and dew point 9(m)).
a)
Include all meteorological parameters measured at the primary tower.
b)
If necessary, substitute missing values with local/NWS data to achieve the 90$ joint data recovery.
Explain the methods used to substitute missing values.

E451. 17 2.7.4 a)
Present the period of record used in Table 2B-40.
b)
Indicate which meteorological measurement levels are tabulated i n Table 2B-52A.
c)
Explain the methodology used to substitute missing hourly relative humidity and dew point temperature measurements in Tables 28-44 and 28-51, respectively.
Present the relative humidi ty and dew point tempera-ture data recovery by month for 1974-1976 as shown in Table 28-52A.
E451. 18 6.8 (Regula-tory Guide
- 1. 23)
Environmental Measurement and Monitorin Pro ram l.
Explain what corrective action was taken to resolve the poor data recovery (less than 90$ ) for measures of atmos-pheric moisture prior to 1978.
What maintenance and calibration procedures are currently being used to insure adequate data recovery?
2.
Present the most recent available onsite measurements of atmospheric moisture (dew point) since 1978.
The data summaries should show diurnal and monthly averages and
- extremes, including the data recovery by month.

Radi oacti ve-Waste Systems E460. 25 (ER 3.5)
Provide the input parameter used for the fraction of feedwater processed through the condensate demineralizers to calculate expected annual gaseous and liquid effluent releases (BWR-GALE Code) from Nine Mile Point,. Unit No.
2 (NMP-2).
For a
BWR with pumped forward feedwater heater drain design (such as NMP-2), the BWR-GALE Code executes the ratio of condensate demineralizer flow rate to steam flow rate of 0.18 for iodines and 0.01 for other nuclides.
It appears that you have used a ratio value of 1.0 (full flow condensate demineralizers) in the BWR-GALE Code while your actual designed ratio value is approximately 0.7 for which the BWR-GALE Code automatically executes 0.18 and 0.01 instead.
