MAINTENANCE INSTRUCTIONS

QCP386 issue 2

Quarterly (routine) and annual (complete) maintenance requirements

Radiographic exposure devices and associated equipment must be maintained regularly by trained and qualified personnel to ensure consistent and safe operation of the radiographic system. The routine inspection and maintenance also ensures the integrity of the Type B(U) transport packages are maintained in compliance with the Type B(U) package, Certification Number USA/9296/B(U)-XX (for XX, enter either 85 or 96 according to the package certification).

Manufacturers base the recommended inspection and maintenance requirements on the system's design, application, materials, anticipated work cycles, environmental factors of use under the normal and abnormal conditions of industrial radiography and while in the transport system. A program of systematic maintenance will prolong the working life of the radiographic exposure device and associated equipment in addition to ensuring safety during use. By most national regulations, routine maintenance of the systems is required at intervals not to exceed 3 months in addition to the radiographer's daily inspections for obvious defects. The complete annual servicing ensures the integrity of the system.

Maintenance program administrators must recognize the need for maintenance intervals that are less than the required 3 month interval especially in cases where the systems are used in severe environmental conditions. Maintenance program administrators must ensure the systems are completely serviced immediately after certain jobs in severe conditions. Extreme or severe conditions may include, but is not limited to:

●Conditions where the equipment was immersed in water or mud.

●Subjected to high-concentrations of particulate such as fly ash or sand.

●Subjected to hot radiography conditions.

●Subjected to salt-water conditions, caustic or acidic materials.

●Subjected to accidental drops or falling objects.

●Whenever subjected to extreme environmental conditions.

The routine maintenance performed every 3 months requires partial disassembly, cleaning, inspection, re-lubrication and operational checks of the system. The complete maintenance (performed once a year) involves a complete disassembly, cleaning, inspection, re-lubrication and operational tests of the entire system.

Equipment maintenance can be performed by trained and qualified individuals within the licensee's organization. AEA Technology QSA service engineers are available to provide maintenance on the systems at the licensee's premises or at one of the service centers.

Routine (quarterly) maintenance requirements 1 Remote controls

Disassemble, clean, inspect and maintain the remote control crank, control conduits and control cable according to the complete service section. Record the results of the inspection and any repairs that are performed. Any components found to be deficient during the inspection must be removed from service until repaired or replaced. Deficient components must be labeled with a status indicator to prevent inadvertent use.

2 Source guide tubes

Clean and inspect the source guide tubes in accordance to the complete service section. Record the results of the inspection and any repairs that are performed. All source guide tubes found to be deficient during this inspection must be removed from service and sent to a service center for repairs. Deficient components must be tagged with a status indicator to prevent inadvertent use.

3 Radiographic exposure device

Clean and inspect the exposure device for wear and obvious damage. Record any defects that might affect safe operation of the exposure device. If deficiencies are found during this
