Revision to Emercency Response Data System Data Point Library Revisions to the Data Point Libraries for the Emergency Response Data System at Prairie Island are attached. These revisions to the Prairie Island Emergency Response Data System Data Point Libraries clarify and update the revised Data Point Libraries transmitted to the NRC by letter dated July 10, 1992. The following changes were incorporated into the attached revisions of the Prairie Island Emergency Response Syste= Data Point Libraries:

i

1. The following Point ID's were changed as shown below:

2. The units for the following points have been changed from "Deg F / Ft" to

+

"Deg F / 50' Meter" or just Deg F.

These points are calculated by I

subtracting the 60 meter height temperature from the 10 meter height temperature:
