- w Docket No. 50-346 Mr. Boyce H. Grier Regional Director U. S. Atomic Energy Commission Division of Compliance, Region III 799 Roosevelt Road Glen Ellyn, Illinois 60137
Dear Mr. Grier:
Toledo Edison acknowledges receipt of your November 5, 1971 letter and enclosure referencing Items 1 and 2, which appeared to be in nonconform-ance with statements in the PSAR, or in noncompliance with 10 CFR 50, Appendix B.
Following a thorough examination of the two areas of concern, Toledo Edison offers the following information regarding corrective actions that have been instituted.
Item 1.
Action taken to resolve the pumped concrete sampling point:
All pumped concrete placements made since the DOC October 13-15 inspection have been conducted under revised Davis-Besse specifications requiring sampling l
at the point of placement. The revisions to Davis-Besse pumped concrete sampling specifications and procedures are now in agreement with PSAR statements and applicable ACI requirements referenced therein.
/
Revised pumped concrete sampling methods have been reviewed thoroughly with the responsible concrete placement contractor and the independent site testing laboratory. In addition, the Davis-Besse construction management organization has been adequately indoctrinated with these specific sampling requirements and informed of the importance of close monitoring in the future.

Mr. Boyce H. Grier 2.
December 2, 1971 Item 2.
Action taken to resolve the improper handling of concrete after its placement:
a) The placing contractor was notified in writing of the violation and his attention focused on the appropriate specification, b) Before the next placement of concrete was made, a thorough planning session was conducted with the placing contractors' supervisory personnel and Davis-Besse Construction Management supervision. The purpose of this session was to ensure that the physical layout of concrete placements will be arranged so as to eliminate the possibility of nonconformances.
c) The placing contractor replied formal.ly, indicating that he has reviewed completely the pertinent specifications regarding placing concrete with his Quality Control Organization.
In addition, he has conducted a discussion with his supervisory personnel pointing out the specifics of the Davis-Besse require-ments and implementation of planning concrete placements so as to eliminate the possibility of nonconformances in the future.
d) The Davis-Besse construction management organization has been indoctrinated on this subject and reminded of their responsibility in maintaining close on-the-job supervision and strict adherence to Davis-Besse requirements by all concerned.
Yours very truly,
./
