Title

Inadequate Procedural Guidance which Resulted in Undemanded Control Valve Movements and Manual Scram

Description

The inspectors reviewed a self-revealed non-cited violation of Technical Specification 5.4.1.a, Procedures, associated with the licensees failure to provide appropriate procedural guidance while performing calibration of a steam line compensator. Specifically, Work Order 4449267, Task 14 did not contain adequate instructions to calibrate a steam line compensator circuit card potentiometer, which led to undemanded control valve opening and closing and a subsequent manual reactor scram.
