I 1.0 APPLICABILITY This procedure is.used to gather the Kewaunee Nuclear Power Plant Meteoro-1ogical Data.
~
2.0 PRECAUTIONS--
2.1 As a minimum; the following meteorological parameters from the Kewaunee Nuclear-Power-Plant Meteorological tower are required to use this procedure..
One wind speed indication (60 meter elevation or 10 meter elevation).
a.
b.
One wind direction indication (60 meter elevatTon or 10 meter
~
elevation).
Vertical Temperature Difference indication (Delta T between 60 c.
meters and 10 meters)or Sigma Theta.
g If this minimum data is not available, acquire and use data from EP-ENV-3E, Manual Determination of meteorological data (Green Bqy Meteorological Data).
2.2 Meteorological data must be re-evaluated every 30 minutes or whenever significant changes occur.

FORM ENV-30.2 LAKE BREEZE EFFECT WORKSilEET DATE TIME Is local wind direction (WD 10 from Fonn ENV-3D.1 or WD 60 if WD 10 is not : -
I.
available) between 20* and 170* clockwise?
NO No lake breen effect (ignore the rest of form)
YES - Proceed.to _ step"II.

a.
Green Bay wind direction:
degrees
~,Q.
s' tenths b.
Average opaque sky cover from sunrise to present knots.
850 millibar wind speed from Green Bay norning sounding
]
c.
Is Green Bay wind direction between 210* and 330* clock' wise?
III.
NO No lake breeze effact (igrore rest of form) q
. YES '- There is a lake breeze effect (go to step IV)
Determine the onset time of the lake breeze from a review of the strip chart' IV.
wind direction data record in TSC. A sudden wind shift from the SW-NW sector to an easterly component will mark the onset time.
