{ DESCRIPTION: ,
I I j
The purpose of the Crawler Control Pot is to indicate to the l radiation sensors in the Crawler logic that the crawler has
! reached its required destination within the pipe. It then ',
4 signals to the sensors that the crawler is required to move either forward or backward. The " torch" as it is commonly called ,
is constructed basically of a " Pot Main Shield" and inside that
- the source itself. The. shield is made of depleted uranium .
! encased in stainless steel and has overall dimensions of 2.56 l
! inches (1.00 cm) in length and 2.625 inches (1.03 cm) in '
j diameter. The source is fitted directly into this shield and i emits a beam at a 90 angle thus making the Control Pot device.
I l 1 This device is currently in storage pending disposal.
l LABELING:
1 i The Crawler Control Pot device is etched with a label that meets the requirements of Section 20.1901 and 20.1904 of the 10 CFR.
I DIAGRAM:
See Attachments 1 and 2.
, CONDITIONS OF NORMAL USE:
I The control pot will be subjected to minimal vibration and/or ;
- environmental conditions associated with the operation of the
- device. The device is handled by persons properly trained in its use and in radiation protection.
PROTOTYPE TESTING:
1 The manufacturer reported that the source used within the device achieved an ANSI N452 classification of 77C64544. The device 4
initially was not tested, but had been used in England for at
- least 2 years without any reported incidents.

DEVICE TYPE: Gamma Indicator Device EXTERNAL RADIATION LEVELS:
The reported dose rate on the side surface of the " torch" is -
20 ares /hr (0.2 mSv/hr) . Dose rates at varying distances in the beam path calculated from the manufacturer's reported data are:
Distanca Dose Rate nar 10 mci Sourca 2 in. (5 cm) 1290 Rem /hr (12.9 mSv/hr)-
11.8 in.(30 cm) 36 Rem /hr (0.36 mSv/hr) 39.4 in.(100 cm) 3.2 Rem /hr (0.032 mSv/hr)
OUALITY ASSURANCE AND CONTROL:
Custom Devices do not require quality control programs because they are built to the unique specification of the user.
Y,TMTTATIONE AND/OR OTHER CONSIDERATIONS OF USE:
- The device is authorized for possession only by the custom user pending disposal.
- The device shall be leak tested at 6 months intervals using techniques capable of detecting 0.005 microcuries of removable contamination.
- Handling, storage, use, transfer, and disposal: To be determined by the licensing authority.
- This registration sheet and the information contained within the references shall not be changed without the written consent of the NRC.
SAFETY ANALYSIS
SUMMARY
Based on our review of the information and test data cited below, we conclude that the crawler pot design is acceptable for possession by the custom user.
