Palisades Plant Bechtel Job 12447-057 10CFR21 Report QA-2991 (11/13/81)

Gentlemen:

C8:D Batteries has received and evaluated sectioned frame welds noted in the reference.

C&D is not able to determine a visual difference of those from the Palisades site and those welds on the similar frames involved in the Wyle Lab tests of 11/16/76. Further, it is obvious the modified installation procedure was contributory.

However, to preclude any subsequent situation, C&D has determined those sites have received similar frames for racks of "L" size cells.

The attached notices have been sent to those indicated.

With this report, we consider our obligations under 10CFR21 to have been fulfilled. We will keep you advised of any adverse con-ditions reported in response to the attached notices, Very truly yours,

/. l. / wP. E .

Dear Sir:

This communication is to advise you of a possible condition associated with a specific battery rack as supplied by CLD Batteries. The circum-stances causing us to call your attention to this matter involve a rack of similar design recently in the process of installation at a new nuclear generating plant. However, in this particular case, the installers chose to relocate the mounting holes for bolting the rack to the floor, and in some cases used metal shims only on one side of the anchor bolts to level the frames of the rack. This procedure introduced forces to the welds un-common to normal installation procedures. The result of this modified technique was to cause fractures in several welds, thereby reducing the structural integrity of the battery rack.

Since we cannot be certain that the weld fractures are directly at-tributable to the modified mounting of this particular rack or to deficient welds, we recommend that you inspect your rack (s) frame members in the specific areas described on the attached drawing.

Please advise us of any deficiencies which you may find so that we may take immediate corrective action.

We wish to thank you in advance for your cooperation in this matter, and apologize for any inconveniences which we may have caused you.

Please contact the writer by letter following your inspection or, if you require immediate assistance, call us at telephone number (215) 828-9000 extension 345 or Mr. David Emery on extension 321.
