/ This morning around 0700 hours, John Reynoso, NRC Inspector, met me at the 30' stairwell and wanted to know the status of 2B008 battery bank. I took him to 2B008 battery room and showed him the qualified spare jar in place where old pilot cell #13 used to be. The spare jar was renumbered M cells 13/14. Old cells 13/14 were renumbered 17/18 and presently stored on the lower tier where the spare jar used be. | |||
/ | |||
#13 is still on v-- John wanted to know why the jar containing degraded cell the rack and not shipped to the manufacturer for Failure Analysis. ?? | |||
I 1 explained that old cells 13/14 were kept on float charge by the single cell rail charger and will be shipped after we install a qualified spare jar with 2 good cells. I took John to the 2B010 battery room (next | |||
. ' door) where a total of 4 extra unqualified 1800 AH batteries are stored C 0 in a mini rack. Because of easy access, spare cells 1/2 should be tested to a Modified Performance test by a single cell tester and E | |||
Srecharge. Then this newly qualified spare jar will be installed in 28008 battery room for future use. | |||
