VOGTLE ELECTRIC GENERATING PLANT EMERGENCY RESPONSE DATA SYSTEM (ERDS)
DATA POINT LIBRARY MODIFICATION In accordance with the requirements of 10 CFR 50, Appendix E, Section VI, item 3a, Southern Nuclear Operating Company submits Emergency Response Data System (ERDS) data point library changes which were completed on August 6,1997. These two data points L7502 and L7503, Containment - South and North Sump Levels respectively, no longer include a LOW ' ALARM limit, and the attached information also provides the Ill ALARM value for all modes ofoperation on both units.
Should you have any questions feel free to contact this oflice.
