Operathns hrmort for January 1969 1.
GT ";PG The scheduled plant outage which was begun on October 18, 1968, was continued throughout this report period.
The installation of the recirculation syste piping was empleted in January.
l The inspection of the main coolant systm was continued with internal inspections of the pressuricer and the primry side of the steam generaLor.
The rain ecolant prap suction and discharge piping, and the stexa generator outlet pipe were radiographed.
The 36 reactor vessel head bolts and acorn nuts werc inspected by the magnetic particlo method (Magna-glo).
No defects or irregularities were detected.
The control chassis for the new flux detector system was installed durin; the month.
Tnis new system will civo redundant flux mapping capability.
Two drive units vill enabic cither of two incoro detectors to raonitor cichteen flux thimbles in the core.
