NRC Letter, Ziemann to Linder, dated December 21, 1978.
Gentlemen:
Your letter (Reference 1) requested verification of correctness of data presented in the reference table as well as additional information pertaining to Safety Topic V-ll.A.
We have revised the enclosed table and verified accuracy and completeness of the information as it applies to isolation of Low Pressure Systems from Reactor Coolant Systems.
If there are any questions regarding this submittal, please con-tact us.
Very truly yours, DAIRYLAND POWER COOPERATIVE va k
