Dear Mr. O'Reilly:
STAFF POSITION ON ELECTRICAL PROTECTION OF CONTAINMENT PENETRATIONS FOR NORTH ANNA POWER STATION, UNIT 2 As stated in our December 21, 1979 letter, we are beginning our submittal of the requested information concerning electrical protection of containment penetrations.
Please find enclosed a binder entitled " Electrical Penetration Protection Pcwer Circuits, North Anna Power Station Unit 2."
This data represents:
1)
Penetration available fault current data.
2)
Contair. ment penetration 12t characteristics under LOCA conditions.
3)
Primary protection current-vs-time curves.
4)
Available fault currents.
5)
Penetration full load values.
6)
Tabular list of penetrations.
Reiterating, this submittal describes protection coordination for electrical pcwer penetrations only.
The remainder of the information reouired by your letter of November 30, 1979, will be submitted by February 15, 1980, as previously agreed.
