Special Report - North Plant Vent Radiation Monitoring System (RMS)

This special report is being submitted pursuant to the requirements of Hope Creek Technical Specification (TS) 3.3.7.5, "Accident Monitoring Instrumentation" Action 81, due to the North Plant Vent RMS being inoperable for greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

A data review determined that the North Plant Vent RMS was reading higher than expected on February 03, 2007. Upon investigation, the check source arm was found disconnected from the solenoid body, which resulted in the erroneous indication. The elevated background radiation levels from the check source rendered the monitor inoperable. This arm was repaired and the system was returned to an operable status on February 12, 2007 at 1618.
