50 306 DPR 60 Revision to Emerrency Resr.onse Data System "Ata Point Library Revisions to the ')ata Point Libraries for the implementation of the Emergency Response Dat System at Prairie Island are attached. These revisions to the Prairie Island Emergency Response Data System Data Point Libraries clarify problem areas identified by the NRC Staff during their review of the original Data Point Libraries transmitted to the NRC by our letter dated October 28, 199%. The following changes were incorporated into the Prairie Island Emergency Response Data System Data Point Libraries by the attached revisions:

1. The following Data Point Library data points were clarified.

i Point ID 1U5011A - Reactor Vessel Level Point ID IU5007A Pressurizer Level Point ID 1U5153A Containment Sump Narrow Range Level Point ID IU5017A - Containment Rump Wide Range Level Point ID 1D5026A - Steam Genet r Blowdown Radiation Point ID 1D5068A - Refueling h er Storage Tank Level Point ID 1D4109A - Wind Direction

2. The Data Point Library high and low range headings were corrected.

Please contact us if you have any questions with respect to the attached information.
