SAFETY ANALYSIS
SUMMARY
1 No formal safety evaluation of the gauge was performed by NRC.
The device was evaluated when Harrel, Inc. was issued their general distribution license.
However, a registration l
certificate for the device was issued by NRC on February 10, l
1983, based on information submitted in Harrel's_ general l
distribution license application.
i The Model TG-603 was an earlier design of the Model TG-601 manufactured by Harrel, Inc.
The Model TG-601 superseded the Model TG-603 and, as of_the date of this document, the Model TG-601 is still being actively manufactured and distributed by Harrel, Inc. to general licensees.
l According to Harrel, Inc., Model TG-603 gauges exist in the field i
and Harrel, Inc. is still providing leak testing and maintenance j
for these gauges.
