L&D BATTERXES, DIVISION OF ELTRA CORPORATION ORGANiiATH3N: PLYMOUTH MEETING, PENNSYLVANIA REPORT NO.: 99900765/82-01 INSPECTION RESULTS: PAGE 2 of 3 A. VIOLATION: Contrary to paragraph 21.21 of 10 CFR Part 21, procedures had not been adopted to implement 10 CFR Part 21. B. NONCONFORMANCES: None C. UNRESOLVED ITEMS: None D. STATUS OF PREVIOUS INSPECTION FINDINGS: None. This wa; the initial inspection of C&D Batteries, Plymouth Meeting, Pennsylvania. E. OTHER FINDINGS OR COMMENTS: 1. Regional Requests a. A 10 CFR Part 21 report by Bechtel Power Corporation, Ann Arbor, Michigan, was made concerning battery rack defective welds. During modification and installation of the battery racks at the Palisades Nuclear Plant Site, several defective welds were observed. C&D, Bechtel, and Consumer Power personnel inspected the defective welds at the Palisades site on October 14-15, 1981. On October 16, 1981, Bechtel personnel inspected the prototype rack at Plymouth Meeting, Pennsylvania, (Prototype rack had been seismically tested by Wyle Laboratory, Huntsville, Alabama on Wyle Job No. 43450, December 7, 1976.) Subsequent to these inspections the following actions were taken in regard to the rack weld deficiencies: (1) C&D weld procedure attachments 1, 2, & 3 were added to C&D Welding Specification Section "B" W-1B by Rev. 2, on October 18, 1981; (2) the defective racks have been replaced at Palisades; (3) 20 RD-660 Frames, 8 RD-924 Frames, and 40 RE-2089 Brackets were returned to the East Greenville, Pennsylvania, C&D plant by Bechtel on C&D Return Material Authorization 22377; and (4) the USNRC RI and seven customers were notified by C&D of the battery rack deficiencies. (See Follow-up Item E.3.) b. A Licensee Event Report by the Diablo Canyon Plant Engineer was made relative to cracking observed in the cells of the station ~ batteries. A C&D field representative visually inspected 300 cells (5 batteries) at the Diablo Canyon Nuclear Plant. Ten of a
ORGANiiATION: C&D BATTER 1ES, DIVISION OF ELTRA CORPORATION PLYMOUTH MEETING, PENNSYLVANIA REPORT NO.: 99900765/82-01 INSPECTION RESULTS: PAGE 3 of 3 the cells were found to be cracked / crazed, and one active cell was determined to be seeping. Two other cells with seepage had been removed and were stored in the Diablo Canyon site maintenance shop. At Millstone Nuclear Generating Stations 1 and 2, 142 cells were visually inspected by C&D personnel, with 3 cells being found crazed and no dampness evident on the bottom of the cells. Twenty percent of the total rib areas in 120 cells at the Vermont Yankee Nuclear Generating Station were also inspected by C&D personnel with this inspection not revealing any leakana, dampness, or crazing / cracking of the containers. In a letter to the USNRC RI, C&D Batteries stated that as a result of the above nuclear site inspections, and field inspections of the condition over the past nine years in both utility and telephone sites, they did not believe the condition represented a " substantial safety hazard." In May 1972, the plastic cell container (type purchased in 1969 for use at Diablo Canyon) was redesigned and the integral rib block was replaced by a floating rib. Pacific Gas and Electric Company, P. O. 4R56705 (November 6, 1981), was placed with C&D Batteries to replace the integral rib block cell batteries with redesigned batteries. USNRC RI and 20 C&D custemers were notified of these deficiencies. c. A 10 CFR Part 21 report by Alabama Power Company's Farley Nuclear Plant was made concerning a defective post seal design that allowed electrolyte fumes to escape. C&D corrected this deficiency in early 1973; the new post seal utilizes a pure lead bushing molded into a hard rubber casing which, when cemented in place, reduces the electrolyte fumes which escape. Farley was the only nuclear site which used batteries with the original design, C&D replacement batteries utilizing the new seal design were shipped to Farley on December 26, 1980 (Alabama Power Company No. 68501). 2. Implementation of 10 CFR Part 21 - Posting in accordance with 10 CFR Part 21 was accomplished at the Plymouth Meeting, Pennsylvania plant. (See A above for violation on paragraph 21.21 notification requirements.) 3. Follow Uo Item - The adequacy of welding controls for battery rack fabrication was not reviewed during this inspection. This subject and responses from C&D customers in regard to battery rack deficiency notification will be examined in a subsequent inspection.
