Dear Sir:
Subject:
Three Mile Island Nuclear Station, Unit 1 (THI-1)
Operating License No. DPR-50 Docket No. 50-289 Revised Emergency Response Data System (ERDS)
Data Point Library Sheets Pursuant to 10 CFR 50 Appendix E, Part VI, Section 3.a, attached are revised data point library sheets for the THI-1 Emergency Response Data System (ERDS).
These changes became effective on August 4, 1994, and do not affect the transmission format or computer communication protocol. The following is a summary of the attached changes:
Point ID
' Changes i
A0992 New point measures wind velocity at site between 0 and 100 mph.
A0993 New point measures wind direction at site.
A0995 New point measures temperature delta t between 150 ft. and 33 ft.
A1000 New point measures radioactivity in plant water discharge after dilution.
Sincerely,
[d W
