VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 NORTH ANNA POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM NRC letter dated October 25, 1990 contained a survey requesting detailed hardware, communications, data point, and administrative information to assist the NRC's contractor in designing Emergency Response Data System (EROS) interfaces. In our letter dated April 11, 1991, Virginia Electric and Power Company submitted this requested information for North Anna Power Station and a partial listing of this information for Surry Power Station. Corrections have been made to some of the North Anna data base records that were previously transmitted in the April submittal.

These corrections include some typographical errors and some corrections made as a result of discussions with the NRC's EROS contractor. This letter forwards the remaining survey information and data point library for Surry Power Station as well as corrected North Anna data point library information as summarized in Attachment A.

Attachment B contains the detailed information.

t If you have any questions concerning this matter, please contact us.

The controller operates the charging water flow control valve (FCV-1122) to maintain a preset charging fl_ow in conjunction with a signal from the pressurizer level instrumentation. The two signals maintain pressurizer level within the proscribed band and limit the maximum and minimum charging flow rates .

The controller operates the charging water flow control valve (FCV-2122) to maintain a preset charging fl~w in conjunction with a signal from the pressurizer level instrllllentation. The two signals maintain pressurizer level within the proscribed band and limit the maximum and minimun charging flow rates .
