Freeman TELEPHONE : (504) 464-3352 REPORTING PERIOD : May,1996 Date Duration Shutdown Cause, Comments and Number (yymmdd) Type (Hours) Reason Method Corrective Actions 96-01 960517 F 58.3 A 3 Failure of the voltage regulator in the 'A' MG (Motor Generator)

Set caused the exciter field current & resulting output voltage to increase. This caused the 'B' MG Set to trip off shortly before the fuse blew on the 'A' MG Set. All power was lost to the CEAs, allowing the CEAs to fully insert, scraming the reactor.

Refer to LER 96-006 for more details.
