Contrary to the above, licensee personnel f ailed to follow SI-83 on Septerrber 3, 1988, while performing work on 0-RB-90-101. As a result, an Auxilitry Building Isolation occurred.
l This is a Severity Level IV Violation (Supplement 1).
B.
Technical Specification 3.3.1 requires the reactor instrumentation listed j
in table 3.3-1 to be operable and that table notation 6 be entered as the Action Statement when less than 4 channels of Overpower Golta T Trip or less than 4 channels of Overtemperature Delta T Trip are.,cRABLE.
