| Title | Process Instrument Shutter Failure |
| Event Description | During a routine semiannual periodic inspection, a process gauge with a 15 milliCurie Cs-137 source was identified to have a stuck shutter. The gauge was an Ohmart Model SHF1-A45, S/N 09236K. The instrument is permanently installed on a distillation column about 30 - 35 ft. from the ground. The integrity of the gauge is fine. Surveys indicated that radiation levels surrounding the gauge were less than 1 millirem per hour.
The licensee plans on having the gauge repaired by the manufacturer. |
