from plant safety systems, and that such isolation will be. adequately

verified, validated,~and documented.' (50-331/86020-02) (Section 1.2.2.3)_- -

4. Ensure that the'followingssix' factors, which can adversely affect'offsite

dose calculations, are corrected o'r;are: adequately compensated lfor:--

  • Wind speed and possibly wind direction measurements, for at least

the northerly direction are significantly affected by-meteorological '

tower wake effects;

  • The reliability of the onsite meteorological data isisuspect as the

senso'rs output signals are-processed by heat sensitive equipment ~

kept in a structure which is not air-conditioned; ,

  • The meteorological data reliability.is. suspect as signal' conditioning-

equipment is not electrically protected. from power-surges; ,

  • - Computerized meteorological data. quality-control checks are generally

~

too rudimentary to identify and eliminate highly suspect values;

  • The power-law relationship used'to estimate wind. speed at~the

offgas stack height is inappropriate; and

  • A Table in EPIP 3.3 that'could be used to convert a weath~er t

observation into an atmospheric stability class is incorrect.

5. . Develop procedures and provide related training to ap r riate emergency

response personnel to enable.them to retrieve and dis 1 historical-
