Gentlemen:

Subject: Resident Inspection 50-423/85-12 (3/18/85 - 4/22/85)

This letter forwards NRC findings from a routine safety inspection of the Millstone

Nuclear Power. Station, Unit No. 3. These findings have been discussed by Mr.

T. Rebelowski, our NRC Senior Resident Inspector, with Mr. D. Miller and other

members of your staff.

During this inspection, testing and flushing evolutions resulted in flooding in

part of the Engineered Safety Features building. That flooding was found to in-

volve a violation of NRC requirements as cited in the enclosed Appendix A to this

letter. Please reply to_that violation in accordance with the instructions in

Appendix A. In addition,~please address in your reply the consideration that both

this' event and the October 1984 introduction of salt water into the auxiliary

feedwater system appear to have involved unforeseen activity interactions which

operational activity controls should have precluded.

Your cooperation with us in this matter is appreciated.

Sincerely,

Ori;;inal Signed By

Edward C. Wenzinger, Chief I

Projects Branch No. 3

Division of Reactor Projects
