(2 2i IWhile in mode 3, it was noticed d ing routine surveillance that the auxiliary,

,,,, ,feedwater flow gauge at the auxiliary shutdown coctrol panel was indicating a

o. 1 iflow rate of 50 GPM when no flow was present. It was subsequently declared in ,

,,,,, ;uperable per T.S. 3.3.3.5 which is reportable pursuant to T.S. 6.9.1.13(b). Be-i31,31cause of the availability of a redundant instrument located nearby on the auxil,-

,,,,,;iary feedwater turbine driven pump control board, the loss was not considered

,2,,, isignificant and the health and safety of the public were not affected.  ;
