Radiography Exposure Device DESCRIPTION:
None of these devices have been distributed.
Nordion, after registering the source and device, decided not to market these items.
Therefore, this certificate is for information purposes only.
The Titan radiography exposure device (radiography camera) consists of a titanium shell, lock assembly, "S" tube cast within a painted depleted uranium shield, and a C-990 source assembly.
When the camera is not being used, the camera's entrance (lock assembly side) and exit ports can be sealed using the supplied source guide tube end cap and the bayonet end cap.
In order to use the radiography camera, appropriate guide tubes and controls (drive mechanism) need to be attached to the camera.
The unit is operated by using the drive mechanism to move the source assembly which is attached to a flexible cable from the shielded position to the end of a source guide tube and back into the shielded position.
A bayonet connector is used to attach the controls to the lock assembly.
The titanium shell houses the depleted uranium shield which contains the "S" tube.
Void spaces between the shield and the shell are filled with epoxy foam.
The housing is fabricated from 1.98 mm (0.078 in) thick titanium.
The overall dimensions of the exposure device are 305 mm (12.0 in) long by 171 mm (6.75 in) wide by 257 mm (10.13 in) high.
The source assembly is housed in the titanium "S" tube.
The source tube has an outside diameter of 12.7 mm (0.50 in) and an inside diameter of 9.4 mm (0.37 in).
i The exposure device is equipped with a locking mechanism to prevent motion of the source assembly when in the LOCK position.
It consists of three main components, tne inner plate assembly, i
the selector ring and the outer plate assembly. When the selector ring is in the LOCK position, the mechanism traps the minor diameter of the female connector attached to the source assembly preventing it from movement.
j The functions of the lock assembly are:
(a)
To secure the source assembly in all positions except OPERATE.

1 DESCRIPTION (continued):
}
(b)
To prevent entry into the OPERATE position unless the j
control cable has been properly connected to the source assembly..
l (c)
To prevent entry into the OPERATE position unless the drive control has been installed.
l (d)
To prevent entry into the OPERATE position unless the projection sheath has been securely installed.
a (e)
To prevent the removal of the drive control while the selector ring is in the OPERATE position.
(f)
To automatically lock the source assembly once it has returned from its working position.
At the start of an exposure cycle, the C-990 is secured in the i
S-tube, the selector ring on the lock assembly is in the LOCK position, the bayonet and source guide tube end caps are installed, and the push button 3.ock is engaged.
This is considered to be the transport mode.
To perform an exposure, the radiographer unlocks the camera by using a key to unlock the push button ?ock.
This allows the bayonet end cap to be removed from the lock assembly and allows access to the C-990 end connector.
The control cable is then attached to the end connector (female connector) on the C-990 source assembly.
Once the control cable is attached, the bayonet connector can be connected to the lock assembly.
At this point the controls are connected to the camera, however, it is not possible to move the selector ring into the OPERATE position until the guide tube (s) (projection sheath)is attached.
To install the guide tube (s) the source guide tube end cap needs to be removed.
Then the guide tube (s) can be installed.
Once correctly installed, the selector ring can be rotated into the OPERATE position.
In the OPERATE mode, the source assembly is free to exit from the primary lock and the shield.
The radiographer then uses the drive controls to project'the source to the appropriate site.
Once the exposure has been completed, the C-990 is retracted into the shield.
As it approaches its secure position, the source assembly's locking ball engages an actuator which causes the selector ring to return to the LOCK position.
The selector ring

DEVICE TYPE:
Radiography Exposure Device DESCRIPTION (continued):
must be manually rotated before you perform another exposure.
Regulations require that the drive mechanism (crank, cable, control' sheaths) and guide tubes meet certain performance requirements.
For ease in use in the registration, licensing and inspection processes, these components are registered with the exposure device.
Only associated equipment labeled with " QUALITY NDE Ltd.", or other components approved for use with the Titan as listed on a registration certificate are approved for use with the Titan camera.
See attachments for diagrams of the exposure device (camera', and approved associated equipment that comply with 10 CFR Part 34 requirements.
LABELING:
Two stainless steel labels meeting the requirements of Sections 20.1901 and 20.1902 of 10 CFR Part 20 are permanently &ttached, one on each side of the device.
A stainless steel identification plate is fastened to the top of the device which is labeled with the manufacturer's name, model number, serial number, capacity and radionuclide.
This label includes the weight of the depleted uranium shield and the mass of the unit without accessories (associated equipment).
Each approved guide tube, control tube and control housing is labeled with " Quality NDE Ltd."
The drive cable (male connector) is engraved "Nordion."
The manufacturer has made provisions for attachment by the user of a source identification label.
This label shall bear the following:
(1)
Chemical symbol and mass number of the radionuclide in the device; (2)
Activity and the date on which this activity was last measured; (3)
Model number and serial number of the sealed source; (4)
Manufacturer of the sealed source; and (5)
Licensee's name address, and telephone number.

CONDITIONS OF NORMAL USE:
The Operation and Service Manual supplied with the exposure device contains general information on all of the components of j
the device, recommended safety precautions, operating and emergency instructions, and a section on maintenance of the unit.
The Titan has been designed for the conditions likely to be encountered during use.
It is constructed from materials that do i
not break down in the -40*C (-40*F) to 55*C (131* F) temperature range.
The source guide tube and control cable sheath should not contact any surface having a temperature greater than 60*C (140*F).
These devices will typically be used in environments associated with industrial radiography.
These environs subject the component to extremely harsh environmental use conditions.
Caution should be taken when using these source assemblies so that the assemblies are not subject to conditions greater than those stated for an ANSI classification of 77C43313.
i PROTOTYPE TEST A prototype Titan and associated equipment (guide tubes, source assemblies, control tubes, drive cable and crank) were subjected to the tests prescribed in ANSI N432 (1980) and performance requirements listed in 10 CFR Part 34.20.
The Titan and associated equipment passed all the tests and performance requirements with the exception of the endurance test specified in Section 8.9 of ANSI.
The manufacturer subjected the prototype to a torque value representative of the actual load a radiographer could exert on the drive cable.
Based on the test data and engineering analyses provided by the manufacturer, this exposure device is deemed to meet the performance requirements of Section 34.20, 10 CFR Part 34.

requirements of ANSI N432-1980 and Section 34.21, 10 CFR part 34.
4 OUALTTY ASSURANCE AND CONTROL:
I Nordion employs a quality control program to insure that each component is manufactured to the specifications furnished to the NRC.
This program complies with the terms and conditions of Subpart H, 10 CFR Part 71 and conforms to the American National Standard's recommendations for quality assurance and control programs.
A copy of this program is on file with the Source Containment and Devices Branch.
LTMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
e This registration sheet and the information contained in the references shall not be changed without the written consent of the NRC.
