Final Report of 10CFR50.55(e) Item on Grout Spill into y Penetration (#48)

Dear Mr. Keppler:

On December 3,1981, Detroit Edison's Mr. H.A. Walker, Supervisor-Con-struction Quality Assurance, telephoned Mr. J. Konklin of NRC. Region III to report on a problem with Grout Spill 'into penetration at tne Fermi 2 site.

In grouting around flued head structural steel, the form broke allowing grout to flow into the penetration sleeve of penetration X-43. Approxi-mately one half of the two to three inch clearance around the penetration was filled with grout, with additional grout believed to be between the liner plate and the concrete of the drywell.

The grout his been removed using a hydro-lance and a vacuum hose. Visual inspection utilizing a boroscope was performed to assure all grout had been removed. This matter has been discussed with the contractors res-ponsible for the grouting and the formwork and appropriate action has been taken to prevent recurrence.

If ycu have questions 'concerning this matter, . please contact Mr. H.'A. Walker, Supervisor-Construction Quality Assurance.

Very truly yours,
