i r7m, that when the lamp was being replaced, the socket turned and shorted. its g leads resulting in a blom fuse which disabled the 125v Dc supply and thus 3

the ability to start the B EDC.

The diesel was tested and returned to i

f7TD i servies within 3 hrs. The redundant A EDG was available to supply ESF t

, equipment as described in FSAR Section 8.
